In Wednesday’s Brief 50, the protective feature was Japan’s local construction workforce, the crews who strengthen buildings before an earthquake and repair them after one, except that workforce is shrinking. Today, the economic moat is the flood protection Copenhagen residents agreed to pay for through their wastewater bills.

Copenhagen’s cloudburst plan has been cut, but not in the way the word suggests. The budget wasn’t cut. It rose, and the plan now costs DKK 15 billion. (DKK is the Danish krone.) What was cut is the protection standard that water bills cover. For future work funded by water tariffs, it dropped from a 100-year storm to a 10-year storm. Projects already underway keep the 100-year standard.

Here’s what that means in practice. The protection standard was the biggest storm the system is built to handle without flooding.

A 100-year standard sizes pipes, tunnels, and green streets to handle a 100-year cloudburst. That includes every 10-year rain event, since those are smaller.

A 10-year standard sizes them to carry only rain up to the 10-year level. Any storm bigger than that overflows onto streets and into basements, whether it’s a 20-, 50-, or 100-year storm.

The result is that protection shrinks. The old standard, designed to handle huge water volumes, already covered small, frequent storms by default. The loss is protection for the big, rare ones, which do most of the damage.

A 100-year rain, or cloudburst, implies a severe flood in water volume, and it has about a 1 percent chance of falling in any given year. A 10-year rain is less significant but has about a 10 percent chance of occurring in any given year. The U.S. Geological Survey points out that 100-year floods can happen two years in a row.

So if the model city for self-funded flood defense can scale back its defenses, who’s safe?

The Moment

On August 25, 2026, Copenhagen’s Finance Committee recommended long-term loans of DKK 82.9 million to pay off six climate adaptation projects already finished and running.

In public finance, cities often pay for a project with short-term money while it’s being built. Once it’s finished and the final cost is known, the city borrows new money to move that cost into a long-term loan of up to 25 years. The city passes the interest and repayments on to HOFOR, the utility whose wastewater tariffs fund the plan, so the city incurs no borrowing costs.

Three weeks after recommending loans to pay off those six completed projects, the City Council, the Borgerrepræsentationen, approved five new projects worth DKK 74.9 million in 2027 prices on September 17, 2026, also financed through HOFOR’s wastewater tariffs. However, the minutes state that the service level for tariff-financed climate adaptation has now changed from a 100-year event to a 10-year event. The vote was 43 for, with 12 abstaining.

Under the original plan, no more than 10 centimeters of water could stand at the boundary between public and private space during a 100-year rain.

The Story

Why did Copenhagen set the bar so high in the first place? On July 2, 2011, a cloudburst hit the city. A year later, Forsikring & Pension, the Danish insurers’ association, revised its tally of insured damages from an initial estimate of DKK 3 billion to about DKK 6 billion. The revised figure covered 90,644 claims, with 20,564 commercial claims accounting for roughly half the cost.

A Nordic insurance trade journal reported in 2011 that, after that event, some insurers told flooded customers such damage wouldn’t be covered in the future, and some customers had their policies canceled. At the same time, other insurers raised prices or deductibles. In other words, Copenhagen has already repriced once.

The community responded by paying for its own protection.

On November 26, 2015, the City Council adopted a 20-year cloudburst plan. HOFOR financed its above-ground surface projects through wastewater tariffs. The plan’s investment framework totaled DKK 11 billion in 2015 prices and also included private money, such as what landowners pay to disconnect their buildings’ rainwater from the sewer. The city originally planned about 300 surface projects. By 2023, it had reduced that to 242 because some weren’t needed and others were moved underground into pipes.

Then the national rules changed. In May 2020, politicians agreed on how wastewater utilities would pay for climate adaptation. The Folketing, the Danish parliament, passed the law in December 2020, and it took effect on January 1, 2021, after Climate, Energy and Utilities Minister Dan Jørgensen signed it. Under the new rules, a project paid for by water tariffs must be cost-effective and, under certain conditions, set at a socio-economically appropriate level.

Vandsektortilsynet, Denmark’s water sector regulator, says the purpose was to help protect consumers against unnecessarily high water prices. That was a cost decision. It wasn’t a finding about how often floods happen.

For Copenhagen, the city says water bills can now pay for physical construction to protect against a storm with about a 10% chance of hitting in any given year. In the inner city, it expects to protect against heavier, rarer storms, with about a 3% to 5% chance in a given year. Under the old standard, the system was built for a storm so severe it had only a 1% chance of occurring in a given year. The old rules still apply only to projects that began construction before January 1, 2027.

On December 12, 2024, the city formally dropped 179 planned projects at the planning stage, most because they could not start before the national deadline. The City Council approved that without a vote. Seven parties added a joint remark to the record, saying they agreed with great regret to annul 179 cloudburst projects, and that most were annulled because new legislation no longer lets the city protect to the level it expected.

In September 2024, Line Barfod of Enhedslisten, the city’s Mayor for Technical and Environmental Affairs, told the Danish news site Altinget the downgrade was completely absurd.

A draft status report from November 2025 says that before the law took effect, about 240 surface projects were planned to the 100-year standard. About 58 will be built to it, and 23 are in operation; six opened in 2024 and 2025. Of the DKK 4.6 billion frame for surface projects, DKK 1.7 billion (37%) had been committed in 2025 prices.

The word ‘cuts’ is what misleads most about the budget. The frame rose from DKK 11 billion in 2015 prices to DKK 15 billion in 2025 prices. The city’s own report says DKK 2.4 billion of that rise is simply an adjustment for higher prices. About DKK 1.6 billion of the rise is real, mostly because the tunnels cost more than assumed and some surface projects are being built as pipes instead.

The tunnels are the plan's backbone, and they come late. The Kalvebod Brygge tunnel is expected in 2027 and will drain about 200 hectares from Frederiksberg Øst and Vesterbro. The Valby tunnel is expected in 2028, and the Svanemøllen tunnel in 2033.

The CIP Foundation, in a June 2026 report on climate adaptation in Denmark, says Copenhagen’s cloudburst tunnels have been in the pipeline for 15 to 20 years, not because construction takes so long. The delay is in the decision-making, not the engineering.

Structural Forces

What holds a community’s flood defense up, and what pulls it down? I see four forces.

Force one: the community’s balance sheet works. The August 2026 loans weren’t the first. In June 2025, the city’s Technical and Environmental Committee approved DKK 82.6 million of long-term loans for three finished projects, at interest rates from 2.41% to 2.62% and terms of up to 25 years. HOFOR pays the costs through the wastewater tariffs, and the loans don’t count against the city’s available borrowing frame. In other words, residents’ water bills carry the debt, not the city budget.

Force two: the nation sets the ceiling. Across Denmark, utilities commissioned 104 climate adaptation projects from 2021 to 2025 for about DKK 2.1 billion, and 85% of that investment was in the Copenhagen area or Aarhus, according to Vandsektortilsynet. Water consumers cover those costs overwhelmingly through their tariffs. And in 2025, 57% of the capital investment was built to protect only against storms that have about a 20% chance of hitting in any given year. The community still pays, but the rule decides how much protection that buys.

Force three: the storms haven’t stopped. The CIP Foundation, relaying an estimate by DTU, the Technical University of Denmark, puts Denmark’s flood damage today at about DKK 9 billion per year, mostly from heavy rain. It says cloudbursts are now the largest annual cause of flood damage. DTU’s model expects about DKK 400 billion of flood damage across Denmark over the next 100 years, in fixed 2024 prices. Those are modeled national figures for every source of flooding, not Copenhagen alone. The 2021 rule was about what consumers pay. It didn’t make the rain any less dangerous.

Force four: insurers carry what the defenses don’t. In Denmark, ordinary home and contents insurance covers cloudburst damage. Storm surge from the sea is different, and owners can be covered through Naturskaderådet, the state’s natural damage council. Private insurers price cloudburst risk. Forsikring & Pension says Denmark saw almost 23,000 cloudburst claims in 2023, the highest number since the Copenhagen storm of 2011.

Back in September 2024, Pia Holm Steffensen, the association’s deputy director, told Altinget that insurance prices would, all else being equal, rise, and that the industry’s worst case would be homeowners who could no longer buy cloudburst coverage. Then in January 2025 she told Bolius, a Danish homeowner information service, that insurers differed on whether to raise premiums for everyone or price each property separately. The one bright side was that the cancellations after 2011 hadn’t returned as a trend.

As of 2026, the CIP Foundation expects premiums for cloudburst coverage to rise in the most exposed areas, and it warns that some areas and properties may no longer be insurable in the long term.

The Next Chapter

The next date that matters is January 1, 2027.

I suspect that after January 1, 2027, Copenhagen will appear as two cities on a flood map. Some catchments, meaning the areas that drain into the same set of pipes and surface projects, keep protection built to the old 100-year standard. Others will meet the new 10-year protection standard. I expect the first market sign in the downgraded catchments to come as cloudburst deductibles or exclusions at insurance renewal, not a headline premium change. That’s our forecast, not a sourced fact.

In Copenhagen, after a major cloudburst event in 2011, residents agreed to pay for their own protection through their wastewater bills. A national rule in force since 2021 made that protection shallower for future work. The moat isn’t gone, but it’s shallower and less effective than the community planned. But in the short term it kept their utility bills from increasing…

The Strategic Question

If the model city for self-funded flood defense scales back its protection, whose defenses remain safe?

I suggest you evaluate the following:

First, for each Copenhagen asset, determine which side of the 2027 line its catchment falls on. Is it served by one of the 23 projects in operation, by a project started before the deadline, or by a tunnel due in 2027, 2028, or 2033? Or was its project dropped?

Second, at the next insurance renewal, read the cloudburst deductible and the exclusions, not just the premium.

Third, look beyond Copenhagen. Wherever your assets rely on flood protection that residents or ratepayers fund, ask who sets the ceiling on what they may spend, and when that rule last changed.

The lesson isn’t that community defense fails. A community can agree to the protection, yet someone else may still choose short-term protection (capped water prices) over longer-term protection (preparation for the 100-year water).

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

The plan’s cost—the cloudburst plan’s investment frame — rose from DKK 11 billion in 2015 prices to DKK 15 billion in 2025 prices; DKK 2.4 billion of the rise is price adjustment, and about DKK 1.6 billion is real, mostly due to more expensive tunnels and surface projects built as pipes.

In Monday’s Brief 49, decades of community water conservation in Las Vegas built a cushion, and we found that the moat has depth. Today the moat isn’t water in a reservoir. It’s local crews who can strengthen a building before an earthquake and repair it after.

So for the owner of a 1970s warehouse on Osaka Bay, does a capped, shrinking workforce change the choice between retrofitting and rebuilding?

Market Signal

An earthquake is not a climate hazard, and we don’t count it as climate evidence. It belongs in this series because Japan is the clearest case we’ve found of a community’s labor supply setting the price of resilience, and that’s the risk we’re underwriting today.

On September 26, 2025, the government’s Earthquake Research Committee replaced its 30-year probability for a Nankai Trough megaquake, about 80%, with two model-based ranges: 60% to 90% or higher, and 20% to 50%. The Japan Meteorological Agency’s Osaka office says this reflects a review of calculation methods, not a sudden rise in danger.

The Cabinet Office’s maximum-class estimate, published in March 2025 and modeled by the government, puts the worst case at up to about 298,000 deaths, about 2.35 million buildings destroyed or burnt, and about ¥224.9 trillion in asset damage, across 31 prefectures. That’s a national figure, not one specific to Osaka.

Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT), working from the national labor force survey, counted 6.85 million people employed in construction in 1997. MLIT’s Chubu regional bureau puts the count at 4.78 million in 2025, about 30% lower—skilled workers number 2.96 million, down about 35% from 4.55 million in 1997. And the crew is older. In 2024, 36.7% were aged 55 or over, and only 11.7% were 29 or under.

Since April 1, 2024, Japan’s overtime caps apply to construction. In principle, that’s 45 hours per month and 360 hours per year. Under special agreements, the ceiling is 720 hours per year, under 100 hours in any month (including holiday work), and an average of 80 overtime hours over two to six months.

Notably, Japan’s labor ministry exempts disaster recovery and reconstruction from the 100-hour monthly limit and the 80-hour average. So after a quake, the monthly caps are partly lifted for rebuilding. Before a quake, they aren’t, and preventive retrofit has to happen beforehand.

The crews are also moving to a five-day week. The Japan Federation of Construction Contractors, known as Nikkenren, reports that in the first half of fiscal 2025, 57.4% of building sites closed eight or more days every four weeks, up from 49.3% a year earlier. Those are large general contractors’ own sites, not the whole industry. Fewer working days on a site means a longer schedule for the same work.

Deal Scenario

Let’s look at a modeled scenario, meaning the numbers are not pulled from an actual deal. The asset is a multi-story logistics warehouse of 20,000 square meters on the Osaka Bay waterfront, built in 1975 under Japan’s pre-1981 seismic standard and fully let. In Japan, floor area is priced in tsubo (about 3.3 square meters each), so this building is about 6,050 tsubo.

The owner has three choices.

• Option A retrofits in place, with the building half occupied during the work.

• Option B demolishes and rebuilds.

• Option C holds and does nothing for now.

Japan amended its Construction Business Act in June 2024, and MLIT says the amended law has been fully in force since December 12, 2025. It extends the ban to contractors and owners on significantly short schedules and unjustly low prices, safeguarding both labor conditions and operational feasibility. It creates a mechanism to adjust the contract price when material costs spike during the required contract term. It also requires private owners only to make best efforts to negotiate in good faith, while public owners have a firm duty.

Notice what the Act doesn’t do.

It bans contracting a very short schedule, but it doesn’t assign cost escalation to the owner. In our modeled scenario, we assume the owner bears escalation on half the contract value for any extra months. That’s our assumption, an interpretation of what a required price-change clause plus a banned short schedule does in practice. And it’s enforced. MLIT’s Chubu bureau reports 164 inspector investigations in fiscal 2025.

Now the inputs. For the retrofit, we use ¥62,700 per square meter, the top of MLIT’s fiscal 2024 subsidy-eligible unit cost for buildings at high risk of collapse. It’s a cost reference, not a market quote. The national retrofit program also doesn’t list warehouses as an eligible use. It names commercial facilities, hotels, offices, factories, and similar buildings. Anyone checking Osaka City’s own program would need to ask the city, so we model no subsidy.

For the rebuild, we use ¥840,000 per tsubo. That’s the fiscal 2025 planned average price for steel-frame warehouses started in Osaka, from MLIT’s building starts statistics as tabulated by Nomura Real Estate Solutions. It excludes demolition, which understates rebuild costs.

We assume rent on the existing building is ¥4,000 per tsubo per month. The rebuilt building earns ¥4,390 per tsubo per month, the effective rent for large multi-tenant warehouses in the Kinki region around Osaka in the second quarter of 2026, according to CBRE, as reported by the trade paper LNEWS. Kinki vacancy was just 2.4%, so this market is tight.

Our other assumptions are a 12-month retrofit and a 24-month rebuild; half the rent is lost during the retrofit and all of it during the rebuild; and escalation at 5% per year, the low end of the 5% to 6% annual index rise Nomura reports.

In our modeled scenario, the retrofit costs ¥1.254 billion in work plus ¥145.2 million in lost rent, about ¥1.40 billion in total.

The rebuild costs ¥5.082 billion plus ¥580.8 million in lost rent, about ¥5.66 billion.

The gap between retrofit and rebuild costs is about ¥4.26 billion before labor.

Underwriting Analysis

Test one. How far a labor squeeze stretches the schedule. Each stretch in this test compares the same site before and after it moves to five-day weeks, meaning eight closures every four weeks and 20 working days. The five-day version of the job is slower. A site that closes six days in every four weeks works 22 days. In the US, that's two five-day weeks and two six-day weeks per month. Move it to five-day weeks, and the same work takes 22/20, or 1.10x as long. That’s our illustration. A site with seven closures works 21 days, so the same work takes 1.05x as long. Flip it around, and a six-day schedule finishes the job in 20 divided by 24, or about 0.83x the time a five-day schedule takes. A site that works six-day weeks every week, with only four closures, gives up four working days when it moves to five-day weeks, so the same job takes 1.20x as long. That’s the ceiling we model, and it applies to about 10% of building sites. Weighted across Nikkenren’s building sites, the average stretch is about 1.05x.

Test two. What the stretch costs. In our modeled 1.10x scenario, with a capped 5-day workweek, the retrofit runs 13.2 months instead of 12, and its cost rises by ¥17.7 million due to lost rent and escalation. The rebuild runs 26.4 months instead of 24, and its cost rises by ¥83.5 million. The rebuild absorbs 4.73 times the retrofit’s hit, because it runs twice as long, loses all its rent while it runs, and carries a bigger contract. So labor tilts the choice toward retrofit.

But look at the size. The stretch widens the gap by ¥65.8 million, about 1.5% of it. Even at the 1.20x ceiling, the widening is ¥131.7 million; at the weighted average, it’s ¥33.5 million. Labor is the tilt, not the lever.

Test three. What sets the gap. Construction cost does. Price the rebuild at Osaka’s reinforced-concrete warehouse figure, ¥1.53 million per tsubo, and the gap at 1.10x is about ¥8.5 billion in our modeled scenario. Using a 2022 broker range rolled forward at an assumed 5% per year, about ¥669,000 per tsubo, the gap’s about ¥3.3 billion. That’s a ¥5.2 billion swing compared to about ¥99 million across the whole range of schedule stretches. Rebuild cost is the most sensitive input in this model.

Test four. Who bears escalation? If the owner carried escalation on the whole contract rather than half, the widening would be ¥88.1 million at 1.10x instead of ¥65.8 million. No single assumption moves the widening more, and it’s still small next to the gap.

Test five. Does the rebuild’s rent premium pay for it? In our modeled scenario, the rebuilt building’s ¥4,390 is a 9.75% premium over the ¥4,000 we assume for the old one. With an assumed 85% margin, net operating income rises by ¥24.1 million per year. Recovering the ¥4.26 billion gap from that alone takes about 177 years before discounting. The rent premium doesn’t pay for a rebuild.

Test six. Value and the hold. Valued at 4.2%, the Japan Real Estate Institute’s expected cap rate for multi-tenant logistics at Osaka Port, the rebuilt building is worth ¥6.45 billion in our modeled scenario, or about ¥787 million net of the rebuild’s cost. At an assumed 4.5% cap rate, the retrofitted building is worth ¥5.49 billion, or about ¥4.09 billion net of the retrofit. For Option C, the retrofit costs 25.5% of the building’s value. Holding is rational only if buyers and lenders discount the unretrofitted building by less than that, and only until one of them asks for seismic evidence the building can’t show.

This model ignores the remaining life of a 1975 building after a retrofit compared with a new one. That isn’t modeled, and it’s the real case for a rebuild. If your building has little useful life left, or the wrong floor heights for today’s tenants, the answer can change.

Strategic Implications

Here the moat is the local construction workforce, and it’s draining. There are fewer workers, they’re older, and each one has fewer legal hours.

First, you’re competing for the same crews as the rest of the economy. Nomura reported in July 2025 that electrical contractors’ backlogs ran about 1.6 times pre-pandemic levels, and it tied that to semiconductor plant and data center construction. A warehouse retrofit draws on the same shrinking pool of skilled workers.

Second, labor now has a public price. MLIT raised its public works design labor rate by 4.5% from March 2026, its fourteenth consecutive increase, and a contractor can point to that number in a negotiation. Nomura also reports that actual construction prices run 8 to 9 points above the index, and some large projects reach 1.5 to 2 times their original budgets.

Third, read the contract as a risk transfer. A short schedule can’t be bought, so model the escalation share you’ll actually carry.

Looking ahead, I anticipate that owners of pre-1981 stock who commit crews early will finish first and keep their buyer pool. In a tight Osaka market, a modern box rents at a premium, but that premium is small next to what a new box costs. So retrofit first is the default, and a rebuild has to be justified by remaining life and use, not by rent.

Takeaway

Price the crew, not just the concrete.

In our modeled scenario, labor tilts the choice toward retrofit by about 1.5% of the gap, construction cost sets the gap, and the rebuild’s rent premium doesn’t pay for it.

So remember three things. First, put labor days and the closure calendar into your schedule, and run retrofit against rebuild with the stretch on. Second, get a contractor’s quote for the rebuild before you trust any gap, because construction cost decides it. And third, if you’re counting on a subsidy for a warehouse, ask the city before you underwrite it.

The deal scenario — a 20,000 square meter (about 6,050 tsubo) 1975 warehouse; retrofit ¥1.254 billion in work plus ¥145.2 million in lost rent, about ¥1.40 billion; rebuild ¥5.082 billion plus ¥580.8 million, about ¥5.66 billion; a gap of about ¥4.26 billion.

CRREI modeled scenario · Method: CRREI arithmetic. Retrofit work is floor area times ¥62,700 per square meter, and rebuild work is tsubo times ¥840,000.

A hypothetical building, not a deal. Demolition, subsidies, and the remaining life of the 1975 building.

The stretch ladder and the tests — at 1.10x the retrofit runs 13.2 months and costs ¥17.7 million more, the rebuild 26.4 months and ¥83.5 million more, 4.73 times the retrofit’s hit, widening the gap by ¥65.8 million, about 1.5%; ¥131.7 million at 1.20x and ¥33.5 million at the weighted average of about 1.05x; gaps of about ¥8.5 billion and ¥3.3 billion at ¥1.53 million and about ¥669,000 per tsubo; ¥88.1 million with escalation on the whole contract.

CRREI modeled scenario · Method: CRREI arithmetic. Each step assumes the same site moves to five-day weeks, 20 working days in every four weeks, so the stretch is (working days before ÷ 20). Escalation is contract value times the share exposed times extra months times 5% per year. The ¥669,000 rolls a 2022 broker figure of ¥550,000 per tsubo forward at 5% per year. · Modeled — not a specific asset

A scenario ladder, not a finding. The weighted average uses Nikkenren’s chart shares for its members’ building sites.

The rent premium and the hold — a 9.75% rent premium raising net operating income by ¥24.1 million per year, about 177 years to recover the gap; ¥6.45 billion rebuilt at 4.2%, about ¥787 million net; ¥5.49 billion retrofitted at 4.5%, about ¥4.09 billion net; the retrofit at 25.5% of value.

The premise is that social infrastructure, the habits and institutions a place builds together, helps make an asset durable. On Thursday, we asked whether heat is really pushing European hotel guests north, and found that measured demand didn’t match what travelers told surveys. Today we move from guests to residents, and to an official population forecast.

In July 2026, the growth forecast for Las Vegas lost a decade. Is water the reason, and how much growth can the valley’s water actually carry?

Market Signal

On July 22, 2026, the University of Nevada, Las Vegas (UNLV) released the annual population forecast for Clark County, home to Las Vegas, from its Center for Business and Economic Research (CBER). A year earlier, CBER projected the county would reach 3 million residents by 2045. Its 2026 forecast moves that milestone to 2055.

CBER now expects the county to add about 204,000 residents between 2026 and 2036. Last year’s forecast had about 347,000 over the same period. That’s about 143,000 fewer people, a 41% cut in the decade’s expected growth. In other words, it’s a cut in a forecast, not a loss of people.

CBER projects the county’s annual growth rate to fall from 1.6 percent in 2026 to about 0.6 percent in 2029, then hold relatively steady through 2060. CBER also expects natural change, meaning births minus deaths, to turn negative around 2032. All of it is modeled, not observed.

Why the slowdown? CBER gives three reasons. Birth rates in Clark County run below the national average. Net migration, both domestic and international, is expected to be lower than past forecasts. And a higher share of the migrants who do arrive are retirees, which CBER calls a change from previous decades.

Water isn’t on that list. Despite the headlines, I couldn’t find hard data showing that water, heat, or the new Colorado River rules are causing the slowdown.

Where does the county stand today? The Census Bureau estimates Clark County’s population at 2,407,226 on July 1, 2025. USAFacts, relaying the Census Bureau’s estimates, puts the county’s growth from 2024 to 2025 at about 21,500 people, or 0.9%. Roughly 8,900 came directly from another country, about 8,500 came from elsewhere in the US, and births exceeded deaths by about 4,000.

That mix matters. The Census Bureau reported in January 2026 that net international migration to the US was 1.3 million in the year to June 30, 2025, down from 2.7 million the year before, a decline of 53.8%. In March, it reported that the 50 counties with 1 million or more people, including Clark County, had a combined net domestic migration loss of 637,634.

While the Census Bureau does not make this point, it seems reasonable to me that a county leaning this much on international arrivals will feel that drop.

Case Study

In five weeks this past summer, Clark County got a slower forecast, a new federal rulebook for its main water source, and a lawsuit.

The Las Vegas Valley runs on the Colorado River. In a complaint filed on August 24, 2026, Nevada says its share is 300,000 acre-feet per year, or a relatively meager 3.3% of the water apportioned to the Lower Basin states and Mexico. The Lower Basin states are Arizona, California, and Nevada. An acre-foot is enough water to cover one acre of land one foot deep. The complaint also says the river supplies 90% of the valley’s water.

On August 21, 2026, the Bureau of Reclamation, the Interior Department agency that runs Lake Mead and Lake Powell, released its Record of Decision, the formal decision on how the two reservoirs run from 2027 through 2036. For 2027 and 2028, it cuts Lower Basin deliveries by 1.25 million acre-feet in each year. Arizona takes 760,000 acre-feet of that, California 440,000, and Nevada 50,000.

The operating guidelines for 2027 and 2028 apportion 250,000 acre-feet to Nevada, a 16.7% cut to Nevada’s share. According to Alex Hager at KJZZ, the new rules officially took effect on October 1, 2026, and the Lower Basin states are still finalizing an implementing agreement.

Does a 50,000 acre-foot cut bind today’s taps? No. Headroom is the gap between what you’re allowed to use and what you actually use. Nevada’s complaint puts the state’s 2025 consumption at 198,570 acre-feet. The Southern Nevada Water Authority (SNWA), the valley’s wholesale water agency, says on its own site that Nevada’s consumptive Colorado River use was 212,400 acre-feet at the end of 2024.

Set against the 250,000 acre-foot allocation, that leaves a margin of about 37,600 to 51,430 acre-feet, depending on which year you use. In other words, the adopted cut lands inside the cushion.

Where did that cushion come from? Decades of conservation by the people who live there. But each source counts it differently.

Nevada’s complaint says consumption fell from 325,000 acre-feet in 2002 to 198,570 acre-feet in 2025, despite an increase of 875,000 new residents.

Separately, SNWA says Southern Nevada reduced its per capita water use by 58 percent between 2002 and 2025. Both come from parties to the lawsuit, and they measure different things—the former looks at total use and the latter at per-person use.

So what is Nevada suing over? The complaint alleges the decision would let the Interior Secretary impose an annual reduction on Nevada of 213,556 acre-feet, based on a 3.6 million acre-foot shortage, which it says is about 71% of Nevada’s entitlement.

That number isn’t invented. Reclamation’s own Final Environmental Impact Statement (EIS), the analysis behind the decision, gives Nevada 5.93% of shortages in its long-run modeling. 5.93% of the modeled 3.6 million acre-foot maximum matches the complaint’s number within rounding.

But the Record of Decision says the Department is not adopting the specific shortage volumes, shortage distributions, or conservation activities reflected in assumptions used to analyze the Preferred Alternative. It adopts a maximum potential shortage of up to 3 million acre-feet for the Lower Basin states for 2027 through 2036, allocated under applicable law. In other words, the 71% is Nevada’s description of the deepest modeled case, not a cut anyone has ordered.

And if that case did happen? Taking 213,556 from 300,000 leaves 86,444 acre-feet, which is 43.5% of 2025 use. The governor’s office puts it at less than 86,500 acre-feet per year.

That’s where the cushion runs out. The moat has a depth. The adopted cut sits inside it, and the deepest cut in Nevada’s complaint would go well past it.

Nevada, its Colorado River Commission, and SNWA filed suit in federal court in Nevada against Interior Secretary Doug Burgum and others. They ask the court to vacate the decision, the Final EIS, and the 2027 and 2028 guidelines. KJZZ reported on October 1, 2026, that the lawsuit is still working its way through the legal system, and as a reminder, every claim in the complaint is only an allegation at this point.

Strategic Implications

Driver one is that the base case should be the new forecast, not the old trend. The rental market this lands on is already soft. Lee and Associates, a commercial real estate brokerage working from CoStar data, reports Las Vegas multifamily vacancy at 10.8% in the second quarter of 2026. Asking rent was $1,473 per unit, down 2.25% from a year earlier, with 70% of properties offering generous concessions.

Net absorption, meaning units newly occupied minus units vacated, was only 1,327 over 12 months, against 3,366 units of new supply. That’s about 39% of what was delivered. Another 4,456 units are under construction, with an expected 3.4 years of absorption at that pace. These are a broker’s figures, but next to a forecast that cut a decade of growth by about 41%, lease-up and rent assumptions built on the 2010s growth path look too generous.

Driver two is that water is both a ceiling and a forecast input, not the cause of projected slower population growth for Las Vegas. Since 1996, CBER has produced the forecast with the Regional Transportation Commission of Southern Nevada, SNWA, and a group of regional forecasting partners. SNWA spokesperson Bronson Mack says the forecast supports Southern Nevada’s 50-year water resource plan. So water feeds the forecast as an input and sets the ceiling on how far growth can run. It isn’t what’s slowing growth down.

Driver three is that the water agency is a public-finance counterparty. Nevada Governor Joe Lombardo called this a matter of survival for a community that represents about two-thirds of our state’s citizens. On Census figures, Clark County is 73.3% of Nevada’s population, so the governor understates his case.

His office says the federal analysis skipped the impact of what it calls draconian curtailments on southern Nevada’s $180 billion economy, not a loss estimate. SNWA’s general manager, John Entsminger, said conservation has limits, and the reduced water volume Interior has proposed makes it impossible to meet even this community’s basic needs.

Driver four is the community itself. A valley that cut its total water use while adding hundreds of thousands of residents shows that shared habits can stretch a fixed supply. That record lets Nevada argue in court that it has already done its share, and it keeps the adopted 250,000 acre-feet above current use.

CBER director Andrew Woods says growth isn’t guaranteed; it’s earned through long-term planning and investment in jobs, education and workforce training, healthcare, and other quality-of-life improvements. In other words, the valley’s frugality built the cushion, and that cushion leaves room for growth.

Driver five is that an older inflow changes who rents. CBER says a higher share of new arrivals are retirees. For multifamily owners and build-to-rent developers building single-family homes to lease, that points to smaller, accessible units and away from the young-household renter pool many pro formas assume.

Future Signal

I don't expect the adopted cut to directly affect rents, because the allocation still sits above current use. It shows up at the exit. A 2030 buyer will face tighter market conditions than Las Vegas had in the 2010s. They will have to navigate a slow-growing county (0.6% annually), upcoming regulatory guidelines, and the court’s stance on the decision.

Watch five things.

• First, the next guidelines process, which the Interior Secretary must begin no later than October 1, 2027.

• Second, Nevada’s lawsuit, for an answer, an injunction motion, or a ruling.

• Third, the Census Bureau’s next county estimates, which will show whether international arrivals held up.

• Fourth, CBER’s next annual forecast, which will say whether 2055 holds.

• And fifth, Nevada’s 2026 water use against the 250,000 acre-foot line. The narrower the gap, the shallower the moat.

Stakeholder Takeaway

If you own or develop multifamily or build-to-rent in Las Vegas, replace trend-based absorption with CBER’s July 2026 path. Model the adopted 250,000 acre-feet as today’s ceiling, and treat the complaint’s deepest case as a stress test, not a forecast.

If you lend in the valley, ask the sponsor which population forecast sits under the rent growth, and which year’s water use sits under any headroom claim. That choice alone moves the cushion by 13,830 acre-feet.

On Wednesday, we priced one hailstorm against a Dallas-Fort Worth apartment loan. Today we close the month in Europe, with the question everyone in hospitality has been asked this summer. Is extreme heat moving hotel demand north? The data gives a clear answer, and it isn’t what the headlines say.

The Moment

Heat costs a hotel owner money without breaking anything. In Padua this summer, the local hospitality association said more than 80% of about 600 member businesses reported turnover down around 20% during the heatwave, as terraces emptied and customers moved indoors. Those are restaurants and outdoor seating, and the figures are self-reported, but the same mechanism applies to hotels. Revenue is lost with no physical damage, no insurance claim, and no guest going anywhere else. Reuters reported a Moody’s estimate that the summer 2025 heatwaves cost Europe about €43 billion in lost economic output, against roughly €500 million in insured payouts.

That’s the loss. The capital is doing something else. Nordic hotel deals hit a record in 2025, and the people doing them credit weaker local currencies, revenue-based leases, and hotels that fill in both winter and summer. Cool summers aren’t on their list.

The heat itself is not in question. The Copernicus Climate Change Service is part of Copernicus, the European Union’s Earth observation program. It says western Europe had its warmest June on record in 2026. The month averaged 20.74 degrees Celsius, which is 3.06 degrees above the 1991 to 2020 June average, and beat the previous year’s record.

The Story

The media named the response the “coolcation,” meaning a summer vacation taken somewhere cooler. It’s built mostly on searches and surveys. In July 2026, TT, Sweden’s national news wire service, reported that searches from the UK for July and August stays in Sweden on Trivago, the hotel price comparison site, were up 57% on the year. Those are searches, though, not stays.

So what happened when people actually booked? On September 22, 2026, Spain’s national statistics office published its August 2026 hotel figures. August is the peak of the season, and this was one of Europe's hottest summers on record. Spanish hotels recorded 48.7 million overnight stays, up 1.4% on August 2025, and non-resident nights, meaning foreign visitors, rose 2.8%. The average daily rate (ADR), the average price paid for each occupied room, rose 7.3% to € 166.90. Revenue per available room (RevPAR), which divides room revenue by every room in the hotel, sold or empty, rose 7.0% to €133.10. In other words, foreign demand for Spain rose in the year’s hottest month, and each room earned more.

Eurostat, the European Union’s statistical office, says the EU set another record in 2025, with nearly 3.1 billion nights in tourist accommodation, up 2.2%. Spain alone took 513.6 million of them. In the first half of 2026, Ireland, Malta, and Slovakia were Eurostat’s biggest movers. That isn’t a north-south pattern at all.

The north is growing faster in percentage terms, but from a much smaller base. Statistics Norway counted 8,108,778 guest nights in July 2026, up 6.0%. Greece’s statistical authority counted 31.70 million overnight stays, up 2.0%. Restoring the base, Greece added 621,569 nights to Norway’s 458,987, or 1.35 times as many, in the month the northward story should be strongest.

And the north isn’t heat-proof. In July 2025, sub-Arctic Fennoscandia, meaning Norway, Sweden, and Finland north of 60 degrees latitude, had a 21-day heatwave, the longest on record for the region. A northern premium bets on cool summers.

Has demand moved north, then? Not in any booked measure, at least not yet. What has moved is price in the south, and capital in the north.

Structural Forces

So if the map isn’t moving, what is? I see four forces.

Force one: the season is stretching, not the map. In Spain in 2025, Eurostat’s monthly series show June nights grew 4.02% and September nights grew 2.24%. August grew only 1.22%. In other words, the peak month grew the slowest, and June grew 3.31 times as fast as August. That’s measurable in the country with the EU’s largest tourism base. It affects staffing, capital expenditure (capex), and the timing of covenant tests, the financial ratios a lender requires a borrower to meet.

There is a complication. In Spain, June 2026 fell 1.42%. Was that the heat? UN Tourism, the United Nations agency, recorded a 3% drop in global arrivals in June. It named Middle East flight disruptions, mixed consumer confidence, and elevated oil prices. Heat isn’t on its list. Easter also moved from April 20, 2025, to April 5, 2026, which pulled nights into March. So we don’t attribute the June 2026 decline to heat.

Force two: the growth is price, not volume. Spain’s August revenue per available room grew five times faster than its night count. In Greece, GBR Consulting, a hotel consultancy, says resort revenue per available room rose 11.2% in the second quarter, on occupancy up just 0.5%. ITEP, the Greek tourism research institute, put the average July nightly rate at €190, up from €168. That’s 13.1% more per room, with occupancy up one point. In other words, rate now drives the southern revenue base. Rate can reprice in a single season, while occupancy takes years to rebuild.

Force three: the concentration is the risk, not the location. Eurostat says 31.1% of all EU nights in 2025 fell in July and August. In Croatia, it was 54.5%; in Greece, 41.6%; and in Finland, 24.1%. In Croatia, August nights were 41.1 times January’s. So a Croatian resort earns more than half its year in two months, and the other ten months carry 45.5% of its revenue. Why does that matter to a lender? Heat doesn’t have to empty that hotel to threaten its loan. It only has to shave the peak and push revenue into shoulder weeks, the quieter weeks around high season when the hotel isn’t staffed, priced, or fully open.

Force four: heat isn’t an insured peril, so the loss stays with the owner. That €43 billion of lost output against €500 million of insured payouts is the gap. Swenja Surminski of Marsh, the global insurance broker, said heat itself isn’t a traditionally insured risk.

The market’s answer so far is parametric insurance, which pays out automatically when a measured index such as temperature crosses a set threshold, with no loss adjuster and no proof of damage. Aidan Kerr, who leads public sector solutions for the UK and Ireland at Swiss Re, told Reuters that parametric insurance “can really play a role.” So far the products are mostly in agriculture, and we found none written for a hotel’s peak-season revenue.

The Next Chapter

What did move north? Capital. Cushman and Wakefield, the real estate services firm, puts Nordic hotel transaction volume up 87% in 2025, to €2 billion. CBRE, a rival firm, reports a similar figure of €1.85 billion. Two brokers measuring one market in one year came out 8.1% apart. The direction isn’t in dispute. The number is.

Why are the buyers there?

At a Nordic investment panel, Christian Kielgast of Nordic Hotel Consulting credited the recent fall in local currencies. A weaker local currency makes the same hotel cheaper for a foreign buyer. Robin Stenlund of CapMan Real Estate, a Nordic investment manager, said urban hotels with revenue-based leases offer strong risk-adjusted returns. In a revenue-based lease, the operator’s rent rises and falls with the hotel’s revenue, so the owner shares in the upside.

Jasmine Hopkins of Savills called dual seasonality the differentiator. In other words, the hotel can fill rooms in both winter and summer. Colliers put hospitality at 2% of Nordic real estate deals in 2022 and 2023, and at 6% by 2025. Currency, lease structure, and an under-owned sector explain that deal flow without a thermometer.

Meanwhile, the south is still booking. Meliá, the Spanish hotel group, reported revenue per available room up 11.7% in the first half of 2026. It told the market its third-quarter bookings at its Spanish and other resorts were growing at double-digit rates. Its €7.5 million net loss came from €79.4 million of provisions on leaving Cuba. The loss has nothing to do with heat.

The movement operators actually describe is inside Spain. Stefan de Goeij of Cushman and Wakefield described a move from the concrete jungle cities toward coastal hotels. That’s a shift between assets in the same country and the same currency. For a city-hotel owner, I’d argue it’s worse news than a guest flying to Oslo.

Values haven’t moved either. HVS, a hotel valuation firm, says European hotel values rose 0.2% through 2025. That doesn’t mean nothing is happening. It’s evidence nothing has been priced yet. The appraisal gap this series has tracked since Brief 36 is now arriving in hotels.

Over the next 12 to 24 months, I expect southern hotel income to keep growing on rate. I expect the first stress to show up in shoulder weeks and covenant tests, not arrivals. I expect Nordic hotel pricing to keep rising on currency and lease structure, while demand grows from a small base. And I expect the first lender to ask for monthly revenue concentration at the asset level to set the terms for everyone else. I’ll also be watching the climate insurance alliance the European Commission said it will launch on September 16. By the EU’s own figures, only a quarter of the bloc’s climate-related losses are insured.

The Strategic Question

If you own or lend against a southern European resort, is your debt service earned in eight weeks that heat can shave? And does anyone in the deal know the number?

I suggest you evaluate the following:

• First, ask for the monthly revenue split at the asset level. Eurostat publishes seasonality by country, but we found no European rule requiring a hotel owner to disclose it by asset. That makes it a diligence question.

• Second, split the last three years of growth into rate and occupancy. An income line built on rate is more fragile than one built on filled rooms, whether or not a single guest ever moves north.

• Third, if you’re buying in the north, price the asset on what the buyers themselves named. That means currency, revenue-based leases, and two seasons, not cool summers the Arctic has already shown it can’t promise.

Heat is real, and so is its cost. It just isn’t showing up where the headline says. It’s showing up in the price, in the calendar, and on the owner’s own balance sheet.

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

On Monday, we asked who keeps the savings when a grocery store’s cooling bill falls. Under a triple-net lease, where the tenant pays operating costs, the grocery did. Today the savings are the landlord’s, because apartment insurance is getting cheaper. What is that worth, and what does one hailstorm take back?

Market Signal

The Council of Insurance Agents and Brokers (CIAB), the trade association for large US commercial brokerages, reports that commercial property premiums fell an average of 6.3% in the second quarter of 2026. That’s the fourth straight quarterly decline, the biggest since the second quarter of 2010, when it was 7.0%. Seventy-five percent of respondents saw more property capacity, meaning greater willingness to write coverage. The council also reported that softer conditions led to lower deductibles, in particular for wind and hail.

Three years earlier, Lockton reported average commercial property premium increases of 20.4% in the first quarter of 2023. For apartments, Lockton’s February 2026 update puts renewals on wood frame or better construction down 5% to 15%.

Mid-America Apartment Communities (MAA), a publicly traded apartment real estate investment trust, told investors on July 30, 2026, that its premiums fell by over 12% at its July 1 renewal. It was the third year of reductions, reflecting the national trend, not what a single garden asset gets.

Moody’s says United States severe convective storm losses in the first half of 2026 track roughly half of recent years. Those are thunderstorms that bring hail, tornadoes, and damaging wind. In 2023, 2024, and 2025, they each topped $50 billion. Hail reports for Texas are down roughly 70% from the 2023-2025 average. Nationally, first-half hail reports fell from 7,290 in 2025 to 3,706 in 2026.

The reinsurance broker Gallagher Re put industry storm losses at $22 billion as of June 18, 2026. That’s below the five-year average of $38 billion, and it’s still the eleventh year in a row above $20 billion. Those are nominal dollars. Verisk puts the average residential roof replacement at $17,631 in 2025, about a third above its 2021 to 2024 average, so the same hail now costs more to fix. Labor is doing most of the pushing. In a September survey by the Associated General Contractors of America, more than eight in 10 contractors said they had raised hourly pay, and 29 percent reported effects from immigration enforcement, such as workers leaving or not showing up.

Moody’s also cautions that earlier studies connect El Niño, a periodic warming of the tropical Pacific, to less hail in Texas and Oklahoma, and this year fits that pattern. This suggests a quiet year is a draw from the distribution, not a new distribution. Forecasters expect this El Niño to peak this winter. That research points to another quiet hail spring in Texas, and if La Niña follows, the rebound would reach the 2028 renewals, not the next one.

And the exposure didn’t move.

The data firm Cotality counts more than 235,000 Texas homes hit by damaging hail in 2025. It puts more than $2.2 trillion in reconstruction costs across the Texas Triangle of Dallas-Fort Worth, Houston, Austin, and San Antonio at moderate or greater hail risk.

Isn’t the state helping?

The Governor’s September 16, 2026, action on insurance costs targets homeowners and doesn’t reach apartment policies. The soft market is coming from carriers competing for business.

Deal Scenario

Let’s look at a modeled scenario, meaning the numbers aren't pulled from an actual deal.

The asset is a 262-unit garden-style apartment community in Dallas-Fort Worth. Picture low-rise buildings with many separate roofs. Bought in mid-2024, it faces its refinancing decision in September 2026.

Cushman and Wakefield’s second-quarter 2026 report puts Dallas-Fort Worth effective rent, meaning rent after concessions, at $1,470 per unit per month, with vacancy at 9.6%. Other operating costs are $8,314 per unit per year.

Insurance at purchase is the input nobody publishes.

A Texas broker, Donegan, says the credible data doesn’t support a single Texas per-unit number. So we anchored it to research. A Brookings Institution working paper puts multifamily insurance at 4.7% of rent by 2024. That covers more than 100,000 properties financed through Fannie Mae or Freddie Mac. On this rent roll, that works out to roughly $749 to $829 per unit, depending on whether you count vacancy, and we use $800.

In our modeled scenario, net operating income (NOI), which is income minus operating expenses before debt payments, is $1,790,131 at purchase. At a 5.25% capitalization rate (cap rate), which is the NOI a buyer accepts as a share of the price, the price is $34,097,728. That’s about $130,144 per unit, financed with a 65% interest-only bridge loan of $22,163,523. A bridge loan is short-term debt meant to be refinanced, and interest-only means you repay no principal.

Then we run three insurance paths on the same building.

Path A. The hard market persists. The premium rises 24.3%, the Dallas increase Yardi Matrix measured in 2023, to $994.40 per unit.

Path B. The soft market arrives as reported. The premium falls 12% to $704.00. That’s the middle of Lockton’s range, in line with MAA, and steeper than the 6.3% all-property average in the broker survey.

Path C. The soft market reverses. Path B’s premium climbs 24.3% again, to $875.07.

Underwriting Analysis

Test one. What the soft market is worth in income. In our modeled scenario, the gap between Path A and Path B is $76,085 of net operating income per year. That’s 4.2% of Path B’s income. This assumes every premium dollar reaches the owner. The Federal Reserve estimates that a dollar of insurance costs cuts owners’ net income by about 72 cents, which would reduce the gap to $54,781. We keep full pass-through because Brookings, the later reading, finds the rent response had nearly disappeared by 2024. So $76,085 is the model and $54,781 is the floor.

Test two. Value. At a 5.25% exit cap rate, our modeled scenario adds $1,449,234 in value. It turns a $970,149 loss against the purchase price into a $479,086 gain. But what moves value more? Moving the cap rate 25 basis points either way, from 5.00% to 5.50%, swings Path B’s value by $3,300,514. That’s 2.28 times the whole insurance story.

Test three. Refinancing. The 10-year Treasury yield was 4.96% on September 21, 2026. Our refinance rate is that plus 139 basis points, or 6.35%, on a 30-year amortization. The Federal Reserve raised its benchmark rate on September 16 and signaled one more increase this year, so the pressure on this refinance is more likely to build than ease. Lenders size this loan on the debt service coverage ratio (DSCR). That’s net operating income divided by the annual loan payment. A ratio of 1.25x means income covers the payment 1.25 times. In our modeled scenario, the existing bridge balance would put the coverage ratio at 1.051x on Path A and 1.097x on Path B. Both are under Fannie Mae’s 1.25x minimum.

So what does the owner do? The new loan is sized down to the 1.25x floor, and the owner brings cash to retire the rest of the bridge. That’s $3,529,664 of new equity on Path A and $2,714,487 on Path B. Cheaper insurance saves $815,177 of new equity, and it still doesn’t close the gap. The rate did most of that damage.

Test four. Deductible. Wind and hail deductibles are usually percentage deductibles. Instead of a flat dollar amount, the owner keeps a percent of the total insurable value (TIV), not a percent of the price. Because it’s a percentage of insured value, the deductible grows with rebuilding costs even if the percentage never changes. Fannie Mae’s guide defines that value as the full value of the covered property plus property-related business income, meaning rent lost during repairs.

We assume $150,000 per unit, or $39,300,000 for the whole property. That’s more likely low than high, since Northmarq puts the median Dallas-Fort Worth sale price in early 2026 at $175,300 per unit.

In our modeled scenario, a 2% deductible is $786,000 per occurrence (per storm). Three percent is $1,179,000, which is 64.9% of Path B’s annual net operating income. Five percent is the maximum Fannie Mae and Freddie Mac allow for wind and hail, and it comes to $1,965,000. That’s 108.2% of one year’s income. In other words, one hail event at the agency ceiling costs more than a full year of income.

Test five. Same building, two lenders. Fannie Mae and Freddie Mac, the government-sponsored enterprises known as the agencies, cap the wind and hail deductible at 5% of insurable value, with no dollar cap. The Department of Housing and Urban Development (HUD), in its Mortgagee Letter 2024-05, caps the deductible at the greater of $50,000 or 5% of the insurable value per location, up to $475,000 per occurrence.

On this asset, that’s $1,965,000 against $475,000. The owner keeps 4.14 times the loss on the same roofs, and the loan program, not the building, decides it.

Test six. The hail year. In our modeled scenario, the owner refinances on Path B, and coverage settles at 1.219x after the premium reverses. In the storm year, a 3% deductible takes net operating income down to $591,462 and coverage to 0.407x. At the 5% agency maximum, coverage goes negative, to -0.134x. The building can’t pay its own retention out of the year it happened.

On the same loan with HUD’s cap, coverage is 0.892x. Loan-to-value (LTV), the loan balance as a share of the property’s value, is 60.4%. So the lender’s problem is cash flow, not collateral.

In our modeled scenario, moving the deductible from 2% to the 5% ceiling swings hail-year coverage by 0.812x. A one-third move in insured value per unit is worth 0.271x. The whole premium band is worth 0.012x. The deductible percentage is the input.

Strategic Implications

So what does an owner do with a soft market?

I would spend it on the deductible.

The premium cut is real, and in our modeled scenario it’s worth 4.2% of income. But the risk that breaks the loan is retention, the share of a loss the owner keeps before insurance pays. The broker survey says softer markets are already lowering wind and hail deductibles, so ask for that trade at renewal.

It also runs counter to the recent trend. PwC’s Veronika Torarp told Multi-Housing News that average deductibles rose 22% in 2025. In other words, premiums fell after retention rose.

Second, read your loan program as an insurance decision. The same roofs carry a $1,965,000 ceiling under an agency loan and $475,000 under a loan insured by the Federal Housing Administration (FHA), HUD's multifamily mortgage insurer. Check whether your deductible is written per unit, per building, or per location. The wholesaler Amwins warns owners about that, because one hailstorm can hit every roof on a garden site at once.

Also check how the roofs are valued. Replacement cost pays for a new roof. Actual cash value (ACV) pays replacement cost minus depreciation, so an older roof collects less.

Third, expect to be scored building by building. In January 2026, General Star, a specialty commercial insurer, adopted ZestyAI’s property-level storm model for multi-structure apartment and condominium portfolios. ZestyAI rates individual structures from aerial imagery. The Texas Department of Insurance, the state’s insurance regulator, approved ZestyAI’s hail models for rating back in 2024.

Two assets on the same street with different roofs can now be quoted differently. Age matters, and so does impact-resistant roofing, meaning shingles or panels that passed the industry’s toughest hail test.

For lenders, the distress is already in the data. CRED iQ, a commercial real estate data platform, found 39 of 98 multifamily loans it evaluated below 1.0x coverage, with a 13% multifamily distress rate. I would size the loan on the hail year, not the average year.

Takeaway

Price the retention before you bank the premium.

The soft market is riding on a hail season that didn’t happen.

CRREI modeled scenario · Method: CRREI arithmetic on the sourced inputs. Effective income is units times rent times 12, less vacancy. Net operating income is effective income less other operating costs and insurance, and value is net operating income divided by the cap rate. · Modeled — not a specific asset

Insurance at purchase is anchored to the Brookings share of rent, which gives $749 to $829 per unit, because no published Texas per-unit figure exists. Rent, other costs, and the cap rate stay flat within each path, so insurance is the only variable.

The refinance, deductible, and hail year — Path A to Path B gap of $76,085 of net operating income per year (4.2%), or $54,781 at 72 cents on the dollar; $1,449,234 of value; a 6.35% refinance rate on a 30-year amortization sized to 1.25x, bridge coverage of 1.051x and 1.097x, and new equity of $3,529,664 and $2,714,487; insured value of $150,000 per unit ($39,300,000); deductibles of $786,000, $1,179,000, and $1,965,000 at 2%, 3%, and 5%; hail-year coverage of 1.219x recurring, 0.407x at 3%, -0.134x at 5%, and 0.892x under HUD’s $475,000 cap; loan-to-value 60.4%.

CRREI modeled scenario · Method: CRREI arithmetic. The refinance loan is net operating income divided by 1.25 and by the loan constant for 6.35% over 30 years. The deductible is insured value times the percentage, per occurrence, paid out of the storm year’s net operating income on the Path B loan after the premium reverses to Path C. · Modeled — not a specific asset.

Insured value is an assumption on a replacement-cost basis that includes business income, not the price, and is more likely low than high. One event in one year is modeled, with no recovery above the deductible. Loan-to-value uses the Path C value at a 5.50% cap rate.

On Thursday, we followed catastrophe risk into the bond market, a record market with almost no property owners. Today we come down to a single roof.

When a building costs less to run in the heat, who keeps the money?

Market Signal

The National Oceanic and Atmospheric Administration (NOAA), the federal weather and climate agency, has published cooling degree days for California since 1895. A cooling degree day measures how far the average temperature sits above 65 degrees Fahrenheit on a given day. Added up across the year, it measures heat the way a utility bill feels it, and it’s the standard yardstick for how hard cooling equipment has to work.

The six highest years in that 131-year record are 2020 at 1,206, 2022 at 1,205, 2024 at 1,192, then 2017, 2015, and 2021. All of them have come since 2015.

The same series puts 2023 at 866 and 2025 at 951, both well below the recent ten-year average of about 1,075. So this is a rising trend with wide yearly swings, not a ratchet. An operator budgeting off last summer will be wrong either way. Over the long view, California has warmed almost 3 degrees Fahrenheit since the start of the 20th century.

Pacific Gas and Electric (PG&E), the utility serving much of Northern and Central California, uses Schedule B-19. B-19 is the time-of-use tariff for large commercial customers, so prices change by the hour and the season. Energy costs about 18.6 cents per kilowatt-hour during summer peak (4 to 9 p.m. every day) and 12.0 cents off-peak. On top of that, B-19 charges $46.16 per kilowatt for the store’s highest draw during summer peak, and $37.37 per kilowatt for its highest draw at any hour.

Those are demand charges. In other words, the store pays for both the energy it uses over time, measured in kilowatt-hours, and its highest moment of power draw. B-19 is mandatory once a customer’s billing demand has run above 499 kilowatts for three months in a row. Stores still on the older E-19 schedule must move to B-19 when E-19 expires, currently scheduled for 2027, and their peak window shifts from noon to 6 p.m. on weekdays to 4 to 9 p.m. Supermarket refrigeration runs around the clock and can’t choose between peak and non-peak.

The demand charge is where a cooling technology earns its keep, or doesn’t.

Case Study

The case involves a company called SkyCool Systems, founded out of Stanford by Shanhui Fan, Aaswath Raman, and Eli Goldstein. They have adapted a technology called radiative sky cooling for use on buildings. Their rooftop panels carry a multilayer optical film that reflects sunlight and sheds heat to the sky. That cools fluid without electricity or evaporating water.

The field test ran at two operating supermarkets. One is in Red Bluff, in the northern Sacramento Valley. The other is in Milpitas, south of San Francisco Bay. SkyCool switched the array’s pump on and off at a working store, measured the refrigeration system’s power and capacity, and normalized for weather. Eli Goldstein, SkyCool’s co-founder, prepared the report. The California Energy Commission (CEC), the state’s energy policy and planning agency, published the results in January 2025 as report CEC-500-2025-002.

The Electric Power Research Institute (EPRI), an industry research nonprofit, wrote the measurement plan but had limited involvement in the final analysis because it lacked available project funds. In other words, these figures are SkyCool’s own measurements, published by the state, not a state evaluation.

At Red Bluff, an 80-panel array fed the refrigeration condenser, which dumps the heat pulled from the display cases. SkyCool reports a maximum energy saving of 15%. That’s the best case over the hours the array was working, not an annual average. Refrigeration power demand fell 5 to 7 kilowatts. The array added 30 to 45 kilowatts of heat rejection, a 34% increase. It cut discharge pressure, which the compressor pushes against, by up to 50 psi (pounds per square inch). Over the test period, it saved 27,000 kilowatt-hours.

At Milpitas, a 60-panel array added 10 to 25 degrees Fahrenheit of subcooling. Subcooling chills the liquid refrigerant further, so it absorbs more heat in the cases. The report states a 15% to 20% reduction in energy use, and a 14% efficiency gain when the outside air was below 75 degrees.

The annual figure of nearly 20,000 kilowatt-hours is extrapolated from 340 days of data. It was not measured over a full twelve months. SkyCool also says that, as a precooler, the array only saves energy when the ambient air is roughly 80 degrees or warmer. So the savings come in summer.

Two numbers an owner or a lender needs first are missing. Neither store’s total annual electricity use or cost appears in the report, so we can’t express the savings as a share of the bill. No source we found includes installed cost, price per panel, or payback. Without a cost, there’s no return to underwrite.

So we applied the B-19 rates to the measured kilowatt-hours and kilowatts. This is a tariff illustration, not either store’s bill, since neither tariff is published, and a demand cut only earns the peak charge if it lands on the store’s own peak.

Based on the company’s reported results from its own technology, savings are worth between $2,856 and $7,374 per store per year. Kimco Realty, a large owner of grocery-anchored shopping centers, reports buying $109 million of property through July 31, 2026, at a 5.7 percent weighted-average cap rate. A cap rate is net operating income divided by price, so a lower cap rate means a higher price. At 5.7 percent, the savings capitalize to $50,102 to $129,365.

But whose value is it?

Strategic Implications

Under the lease that dominates US retail, the grocer keeps the savings, and the landlord never sees them.

That lease is the triple-net, or NNN, lease. The tenant pays base rent plus its share of the property’s taxes, insurance, and maintenance, the “nets” that give the lease its name. Maintenance usually arrives as common area maintenance, or CAM, charges for shared spaces such as the parking lot. The landlord typically pays those costs and bills tenants back. Those bill-backs are called pass-throughs, or recoveries.

The law firm Holland & Knight wrote in March 2026 that triple-net leases are most common in retail spaces, and that utilities sit in the tenant’s column. Even a full-service gross lease, where rent covers operating costs, commonly carves out separately metered utilities to the tenant. A supermarket’s refrigeration rack is the anchor’s own equipment on its own meter. The Department of Energy (DOE) named the mechanism back in 2016. The owner covers capital costs, and the tenant covers operating costs.

If you’re like me, that sounds backward, because a cheaper-to-run building should be worth more. Regency Centers, another grocery-anchored owner, defines property net operating income in its 2025 annual report as tenant recoveries, other lease income, and other property income, less operating and maintenance expenses, taxes, ground rent, and termination expense.

A landlord-paid expense gets billed back as a recovery. A tenant-metered utility never appears on the landlord’s statement, either side.

In other words, the savings never reach the landlord’s net operating income. The $50,102 to $129,365 from the case study is value built on money the property owner doesn’t receive.

Kimco reported its same-property net operating income rose 3.5% in the second quarter of 2026, and Regency reported 3.8%. The market is paying full price for grocery-anchored income, and none of that value rests on the anchor’s refrigeration bill.

So where do the savings go? To the grocer, where it matters most.

FMI, the Food Industry Association, reports that grocery profit margins averaged 2.1% in 2025. At that margin, saving a dollar on energy is worth about $47.60 in extra sales.

That sounds large, but a grocer keeps only a sliver of each sales dollar, while a dollar not spent on electricity is full profit. On today’s margin, our $2,856 to $7,374 band is the profit on roughly $136,000 to $351,000 of groceries per store per year.

An owner captures the savings in exactly three structures.

One: the owner occupies the box.

Two: the lease is full-service gross, and the utility is not carved out.

Three: a contract moves the meter.

Energy-as-a-service providers such as Budderfly take over the customer’s utility bill under a standard 10-year contract, so the provider keeps the savings. There’s also an indirect route. Lower occupancy costs strengthen the anchor, which is worth something at renewal. But against a supermarket’s rent, it’s small and slow, and we found no source that puts a number on it.

Does efficiency lift net operating income in general?

The one study that tested it against real owner operating statements is both outdated and not relevant to retail grocery. It is DOE/EE-1568, from May 2017, almost ten years ago. It found a 28.8% rise in net operating income per square foot and a 17.6% cut in operating expenses per square foot for green buildings. But it covers one owner’s 131 office properties, controlled only for building size, and the authors say it wasn’t designed to show causation. No study we found reports the same measure for grocery-anchored retail.

Future Signal

Watch for three things over the next 12 to 24 months.

First, the refrigeration clock just moved. In May 2026, the Environmental Protection Agency (EPA) finalized changes to its technology transitions rule for hydrofluorocarbons (HFCs). HFCs are common supermarket refrigerants and potent greenhouse gases. The changes are effective July 27, 2026.

New supermarket systems may use refrigerants with a global warming potential of up to 1,400 starting January 1, 2027. Global warming potential compares a gas’s heat-trapping ability to that of carbon dioxide. The stricter limits of 150 or 300 now start on January 1, 2032. For remote condensing units, the deadline moved six years, from 2026 to 2032. The grocer usually owns that rack, so the decision to replace it has more time and still rests with the tenant.

Second, watch where retrofit money goes. Commercial PACE, or Property Assessed Clean Energy, is financing repaid through the property tax bill. PACENation, the industry’s trade group, counts $13.5 billion of cumulative commercial PACE investment across 3,837 projects through December 2025. Of that, 55% went to energy efficiency and 3% to resiliency. PACE is overwhelmingly an efficiency instrument, whatever it’s called in a pitch deck.

Third, watch for the independent result. The DOE’s Advanced Research Projects Agency-Energy (ARPA-E) still describes demonstrated energy savings from supermarket installations as a goal of the SkyCool project on its program page. The often-quoted 21% saving from the original Stanford work in 2017 was a simulation of a hypothetical office building in Las Vegas, not a measurement. A full-year, weather-normalized, independently verified result on a commercial building would change this conversation. As of this writing, none exists.

I expect landlords will sell cooling technology on retail roofs through the tenant and via energy-as-a-service contracts, not directly, as long as the triple-net lease holds. Landlords who capture value will be the ones who wrote the meter into the deal.

Stakeholder Takeaway

If you own grocery-anchored centers, read the lease before modeling a cooling retrofit into value. If the anchor is separately metered on a triple-net lease, the grocer gets the savings. Your angle is the renewal, not the net operating income.

If you are a grocer or an operator, the economics are yours, and on a 2.1% margin they’re large. Ask any vendor for two numbers. One is the installed cost. The other is a full-year, weather-normalized result on a store like yours. A vendor that can’t supply both is asking you to buy on faith.

If you are a lender or a buyer, don’t put a pitch deck’s savings into a landlord’s underwriting until you know who pays the utility bill.

If you provide or invest in energy-as-a-service, the lease is the product. You’re buying the meter.

On Wednesday, we looked at New Zealand’s new national rule for building in areas with natural hazards. Today we go to the other end of that question. Once the building is up, who carries the catastrophe, and what do they charge for it?

More and more, the answer is a bond market most property owners have never used.

The Moment

On July 28, 2026, Wrigley Re, Series 2023-1, reached its scheduled redemption date. It was a $250 million catastrophe bond sponsored through a captive insurer (an insurer owned by the business it insures) covering real estate funds managed by Blackstone affiliates. Very few property owners have ever issued one.

The sponsor sets up a stand-alone legal entity between itself and the investors, called a Special Purpose Vehicle (SPV), that holds their investment in trust as collateral and pays regular interest payments (premiums) to investors. These interest payments are called ‘the spread’. When a qualifying catastrophe occurs (like a specific-magnitude earthquake or a hurricane causing a certain level of industry damage), the collateral pays the sponsor’s claims, and investors may lose some or all of their principal. If not, they get it back at maturity.

The trigger decides what counts as a qualifying catastrophe.

An indemnity trigger pays on the sponsor’s actual losses.

A parametric trigger pays on a measured feature of the event, such as an earthquake’s magnitude.

Catastrophe bonds are the best-known insurance-linked securities (ILS), investments whose returns depend on insured losses rather than on markets.

According to Artemis, a specialist news and data site for this market, outstanding catastrophe bonds totaled $65.6 billion as of June 30, 2026. Artemis tracks every Rule 144A deal (bonds sold privately to large institutions without public registration) and the private deals in its own directory. Aon Securities, the investment banking arm of the broker Aon, puts it at $63.4 billion, and Swiss Re’s count sits between the two.

The first half of 2026 set records on every count. Artemis counts $17.98 billion of new issuance across 83 transactions, with 12 first-time sponsors. May alone brought $6.93 billion, the biggest month on record.

Swiss Re names two ILS funds, two national governments, a German insurer, United States primary insurers, and two Lloyd’s syndicates, the underwriting groups inside the Lloyd’s of London market.

Not one is a property owner.

The Story

Blackstone came in small. In June 2021, its captive, Gryphon Mutual, sought $50 million of notes covering the California earthquake on a parametric basis. Price guidance, the spread range floated before pricing, was 2.75 percent to 3.25 percent, against a modeled expected loss of 0.99 percent. Expected loss is the average share of principal the risk model says investors will lose per year.

Two years later, it came back bigger. Swiss Re, which structured the $250 million Wrigley Re 2023-1, called it two ‘market firsts’. It was the first corporate catastrophe bond to cover named storms (hurricanes and tropical storms) on an indemnity basis, meaning that the bond’s payout is triggered and calculated directly by the actual, incurred losses experienced by the bond’s issuer. It was also the first to cover more than one country.

Class A was $100 million, covering the United States and Canada, named storms, and earthquakes in every state except California. It attached at $350 million of losses and ran out at $650 million. The modeled chance of touching that layer in a given year was 0.95 percent, and the modeled expected loss was 0.56 percent. It priced at 6.5 percent, the bottom of its guidance, meaning investors accepted the lowest possible interest rate, of 6.5 percent to 7 percent.

Class B was $150 million of California earthquake, attaching at $750 million and running to $900 million. It priced at 7.0 percent on a modeled expected loss of 1.03 percent. Both classes priced at the bottom of guidance in July 2023, the hardest point of the pricing cycle.

In October 2024, Prologis’s captive, the other real estate sponsor, renewed a $95 million earthquake bond, Logistics Re 2024-1. It attaches its stack of coverage layers at $400 million in losses to the Prologis insurance tower. It covers losses up to $550 million, with a modeled expected loss of 2.6 percent. Against guidance of 6.75 percent to 7.25 percent, it priced at 6.0 percent, 75 basis points below the range. California contributes as much as 95 percent of the expected loss.

A catastrophe bond doesn’t insure a portfolio. It insures a concentration. That bond runs to mid-December 2027.

Each has a captive that can pass risk on. Each portfolio is deep enough, and insured deeply enough, that losses of $350 million to $400 million come before the bond pays a cent. And each sits high enough that traditional insurers price it thinly and capital markets price it competitively.

Structural Forces

Force one: the price of catastrophe risk is falling. Artemis puts the average catastrophe bond spread at 6.63 percent in the second quarter of 2026, down from 7.12 percent in the first quarter and 7.23 percent in the same quarter last year. The average price multiple, spread divided by modeled expected loss, fell from 3.14 to 2.29 over the same period. The average spread above expected loss was 3.74 percent, the lowest since the first quarter of 2023 (3.19 percent). The spread fell 8.3 percent, and the multiple fell 27.1 percent. In other words, investors now accept more modeled risk for each dollar of spread.

Based on Artemis’ numbers, Class A is priced at about 11.6 times its modeled expected loss. Besides the 2.29 market average, it looks as if Blackstone overpaid by five times. It didn’t. That average spans every expected loss in the market, and Class A sat far out in the tail, where investors charge a minimum premium, however remote the risk.

Class B at 1.03 percent priced at 6.8 times. Prologis at 2.6 percent priced at 2.3 times. In every deal we looked at, the multiple falls as modeled risk rises.

Force two: the money keeps arriving. Aon Securities puts total alternative reinsurance capital (capital markets money rather than reinsurers’ own balance sheets) at $144.5 billion as of June 30, 2026. Catastrophe bonds account for $63.4 billion of that, up 17 percent year on year. Twelve-month issuance hit a record $24.9 billion, beating $21.8 billion.

What draws the investment is returns. The Swiss Re Global Cat Bond Total Return Index returned 11.4 percent in 2025, which Artemis calls the third double-digit year in a row, and Swiss Re reports 4.12 percent for the first half of 2026.

Force three: some of that capital reaches ordinary owners, but only indirectly. The broker Marsh reports United States property insurance rates down 13 percent in the second quarter of 2026, the eighth quarterly decline in a row. Catastrophe-exposed programs with premiums above $1 million fell 20 percent. That index reflects one broker’s book, and Marsh names four drivers: strong insurer profits, surplus capital, cheaper reinsurance, and higher investment returns. Catastrophe bond capacity feeds the reinsurance price, which is only one of the four.

Florida is the one place the link is direct and measured. At the June 1 renewals, reinsurance broker Guy Carpenter reported risk-adjusted property catastrophe reinsurance pricing down 15 to 20 percent across many layers, with $3.2 billion of Florida catastrophe bond cover placed for 12 sponsors this year.

Force four: the loss trend hasn’t moved. At September’s annual reinsurance meeting in Monte Carlo, Swiss Re said insured natural catastrophe losses continue to grow 5% to 7% per year. It modeled a 2026 peak-loss scenario of around $320 billion. The calm is real, but narrow. Swiss Re counted $42 billion in insured catastrophe losses in the first half of 2026, 16 percent below the ten-year average and the lowest first half since 2020, even as severe storm activity in the US ran above average. Urs Baertschi, who runs property and casualty reinsurance at Swiss Re, told Insurance Business that 2026’s calm is the luck of the draw.

Soft pricing is a cycle. The loss trend is not.

The Next Chapter

The entry ticket is a balance sheet. Blackstone’s two classes carried $17.00 million per year of spread on $250 million of cover, a blended 6.8 percent. Prologis pays $5.70 million per year on $95 million. Those are spread costs only. Unpublished structuring, modeling, legal, and fronting costs come on top. (Fronting means a licensed insurer issues the policy and passes the risk on.)

The bonds also don’t fill their layers. Class A’s $100 million covered 33.3 percent of a $300 million layer. Logistics Re filled 63.3 percent of its layer. A catastrophe bond is a slice of a tower, not the tower. That structure explains why a year full of disasters can look calm to bond investors. Artemis reports that 78 percent of cat bond limits issued in 2026 use indemnity triggers, a record, and 63.9 percent of outstanding risk is now per-occurrence, meaning it pays only when a single event is large enough, rather than adding up many smaller losses over the year. In 2025, the Los Angeles wildfires caused about $40 billion in insured losses, the largest wildfire loss on Swiss Re’s record, yet cat bond prices fell by only about $200 million. In other words, a year of fires, floods, and tornadoes can leave most cat bond investors untouched.

So the market is dominated by risk it already knows. Swiss Re says more than half of first-half 2026 issuance drew more than 90 percent of its modeled expected loss from United States wind. Insurers and state plans are passing that wind risk on. This suggests a wind-exposed United States property portfolio is the natural next sponsor. For now, most owners buy this capacity secondhand, through their insurer.

The Swiss Re Institute estimates that about 40 percent of United States data center capacity may sit in zones with significant to very high numbers of tornado days. It projects global data center insurance premiums rising from $10.6 billion now to $24.2 billion by 2030, about 2.28 times in four years.

Gianfranco Lot, Swiss Re’s chief underwriting officer for property and casualty reinsurance, told Artemis that infrastructure catastrophe bonds are a very interesting tool the market hasn’t yet seen much of. He added that the economics have to work, and he estimates 80 percent to 85 percent of large hyperscale projects (the giant campuses of major cloud companies) are already reinsured.

Over the next 12 to 24 months, I expect the soft price to attract more non-insurance sponsors, led by infrastructure owners with one huge concentrated exposure rather than diversified real estate funds. Blackstone’s next move will be the most-watched real estate decision here. The price should stay soft only as long as the big single losses stay away from the layers these bonds cover.

The Strategic Question

With capital markets pricing wind risk at the thinnest spread over expected loss since early 2023, are you buying that capacity directly, or secondhand through your insurer?

The following are worth evaluating:

First, the retention. Both real estate bonds paid nothing until an event had cost $350 million to $400 million. Could your balance sheet, captive, and other cover carry that much first, and can your captive send the risk above it somewhere?

Second, the pass-through. Ask your broker how much of this year’s softer reinsurance pricing reached your program, and on which layers. In Florida, risk-adjusted pricing fell 15% to 20% across many layers. If your renewal didn’t move, find out why.

Third, the concentration. Prologis told the market that California carried as much as 95 percent of its bond’s expected loss. Which single region drives your own modeled loss, and would a lender or insurer read that number the way you do?

Blackstone’s bond was scheduled to run off in July, and nothing has publicly replaced it. If you’re in that position, the market has never been more open to you, or more crowded with sponsors who already know how to use it.

On Monday, a court asked whether a firm’s climate words matched its own holdings. Today the test comes from a national planning rule in New Zealand. We’ll price it for a developer before the first shovel hits the ground.

Market Signal

For the last thirty years, New Zealand’s planning and building systems followed a tiered structure. National directives set the overarching framework via National Policy Statements (NPS) and National Environmental Standards (NES). Local councils (regional and district/city councils) wrote rules to implement those national policies.

Currently, New Zealand is undergoing its most significant planning system transformation in over three decades. A split-framework system is replacing the Resource Management Act 1991 (RMA). The first half is the Planning Act, which controls how land is used, developed, and enjoyed. The other half is the Natural Environment Act, which focuses exclusively on environmental protection and enhancement.

Public submissions closed on September 24, 2026, on Auckland Council’s Plan Change 120, which would limit development in areas at high flood, landslide, and coastal risk. And according to the Resource Management Law Association, the bills that replace the RMA passed their third reading in Parliament. They take effect on royal assent, the formal final step that turns a bill into law, with the new system intended to be fully operational by 2030.

Under the new split system, the government is consolidating national policy statements and environmental and policy standards into a single, comprehensive framework: the National Policy Direction (NPD) and National Standards. At a local level, more than 100 separate local plans are being collapsed into just 17 Regional Combined Plans (one comprehensive plan per region).

New Zealand’s National Policy Statement for Natural Hazards (NPS-NH) 2025 was gazetted (officially published in the New Zealand Gazette) on December 18, 2025, and came into force on January 15, 2026.

The NPS-NH risk matrices, hazard criteria, and rules will eventually be permanently integrated into the new statutory tools under the Planning Act (which governs land use and subdivision) to guide long-term development decisions. NPS-NH is central government direction that local councils must follow in planning decisions during the transition. It covers seven hazards: flooding, landslips, coastal erosion, coastal inundation, active faults, liquefaction, and tsunami.

The Ministry for Cities, Environment, Regions and Transport (MCERT)’s National Policy Statement on Natural Hazards – Implementation Guide sets likelihood in seven bands. These bands run from almost certain (10% or greater annual chance) to very rare (less than 0.02%). Likelihood is crossed with consequence to rate risk as low, medium, high, or very high. In other words, how often could the hazard happen, and how bad would it be?

Two policies do most of the work for a developer. Policy 3 says that where development is assessed as very high risk, that risk must be avoided. Policy 6 says climate impacts to at least 100 years into the future must be considered.

New Zealand’s councils are its local governments, and each kept a district plan, the council’s land use rulebook, much like a US zoning code. Building something the plan didn’t allow outright required a “resource consent”. The council granted that permit under the former Resource Management Act (RMA). According to law firm Wynn Williams, councils must now consider NPS-NH when deciding on resource consents.

The Treasury, New Zealand’s finance ministry, estimates the 2023 extreme weather events cost between NZ$9 billion and NZ$14.5 billion. Those were the Auckland Anniversary floods and Cyclone Gabrielle. Private insurers paid about NZ$4 billion, leaving a shortfall of NZ$5 billion to NZ$10.5 billion. The 2020 National Climate Change Risk Assessment put about 675,000 people in inland flood hazard areas, with an estimated 411,500 buildings exposed.

Deal Scenario

Let’s look at a modeled scenario, meaning the numbers are not pulled from any actual deal.

The project is twenty townhouses on a 2,000-square-meter brownfield site (previously developed and usable after cleanup) in Henderson, West Auckland, built to sell. We chose West Auckland because it flooded in January 2023.

Land is priced at three suburb-average houses at NZ$862,700 each, or NZ$2,588,100. Build cost uses the Auckland average from Stats NZ, the national statistics agency, of NZ$3,270 per square meter over 139 square meters, or NZ$454,530 per unit. We add Auckland’s development contributions, council infrastructure fees similar to US impact fees, of about NZ$20,000 per unit, plus a NZ$12,000 consent deposit.

Finance comes from a published non-bank range. The rate is 9.5%, at 65% loan-to-cost, meaning the lender funds that share of the total project cost. There’s a 2% establishment fee and a 1.2% annual line fee on the full limit. We allow six months before construction and eighteen months of build. Each unit sells at the Henderson average of NZ$862,700.

Scenario A is before the hazards rule change. In our model, it makes NZ$2,612,094, a 15.14% margin on gross development value (total sales revenue from all units).

Scenario B adds the policy, i.e., New Zealand’s National Policy Statement for Natural Hazards, or the planning rule. That means a NZ$100,000 quantified risk assessment (the Ministry’s own impact statement says it could cost more for a multi-site development), floor raising to elevate for flood levels at the Ministry’s mid figure of NZ$50,000 per unit, and three months of consenting delay. In our modeled scenario, the margin falls to 7.77%, a profit of NZ$1,340,074.

At the Ministry’s low floor-raising figure, the margin is 11.51%. At the high figure, with a six-month delay, the project loses NZ$259,880.

Of the NZ$1,272,020 in national policy or hazards rule costs, floor raising is NZ$1,076,862, or about 84.7%. The risk assessment is 8.5% of it, and just 0.58% of gross development value. The delay costs NZ$87,667. The paperwork is cheap. The concrete is expensive.

Scenario C tests the buyer.

Cotality, a property data and analytics company, measured upfront discounts of NZ$70,000 to NZ$100,000 on flood-susceptible homes in Mount Albert. If we apply the low end to every unit, the modeled project loses NZ$14,698, a margin of -0.09 %. Applying another suburb’s discount to Henderson is strictly an assumption.

It isn’t the policy. It’s the sale price.

In our modeled scenario, a 10% higher price takes Scenario B to 15.95%, and a 10% lower price takes it to -2.30 %. That swing is bigger than the whole hazards rule policy package, and at Henderson’s 12-month median asking price of NZ$800,750, the margin is 0.88%.

Current listings show smaller two-bedroom new builds in Henderson asking roughly NZ$540,000 to NZ$650,000. Those are asking prices, not sales, but they suggest NZ$862,700 per unit is a generous, not safe, assumption.

Underwriting Analysis

One. Buy the assessment before the site.

Under Policy 3, a resource consent for very high-risk development isn’t available at any price. In our modeled scenario, a failed site leaves the developer out NZ$100,000 for the assessment plus NZ$184,402 in land interest over nine months. That’s NZ$284,402 before any land write-down, which no source quantifies.

The Ministry’s interim analysis in April 2025 said most regulated parties would face marginal costs unlikely to exceed NZ$10,000. A multi-site project is well past that.

Two. Price the floor, not the form.

The impact statement puts floor raising at NZ$20,000 to NZ$50,000, and NZ$50,000 to NZ$120,000 per dwelling. It calls for the total cost, not the marginal cost. We treated it as fully additional, which overstates the hit. It still does the most damage, so get a real quote at feasibility.

Three. Read the insurance tail, because it has grown.

In May 2024, the Reserve Bank of New Zealand, the country’s central bank, found that about 20% of quotes for high flood risk properties carried extra flood premiums averaging NZ$250 or more per year. A newer Treasury data collection, prepared by the consultancy Finity and published in February 2026, found that just under half of quotes in high flood-risk locations carried significant flood pricing. The largest estimated flood premium was NZ$9,250, against NZ$4,250 the year before.

Capitalized at Henderson’s 3.6% yield, NZ$9,250 per year is worth about NZ$256,944 of house value in our modeled example. That’s 3.7 times the Mount Albert discount.

In other words, the insurance premium alone can now set a house price.

The Natural Hazards Commission, formerly the Earthquake Commission (EQC), is the government-owned insurer that sits underneath private home insurance.

For earthquakes, landslides, volcanic activity, and tsunamis, it covers a dwelling’s building to generally NZ$300,000 plus GST (Goods and Services Tax), New Zealand’s sales tax equivalent.

For storm and flood, it covers land only. So landslip damage to the building has a public backstop, while flood damage falls to private insurers. The Treasury’s Cabinet paper also proposes lifting the Natural Hazards levy, the charge on home insurance that funds the Commission, from NZ$554 to NZ$828 per dwelling.

Four. Know which lender you’re in front of.

According to a 2021 guide by broker Lateral Partners, traditional main-bank development lending required a minimum 25% development margin alongside 30% equity, whereas non-bank hurdles sat at 20% or more. Against these benchmarks, the modeled Scenario A never qualified as bankable “main-bank paper,” even before the policy change.

The Reserve Bank raised the Official Cash Rate, its benchmark policy rate and roughly equivalent to the Federal Reserve’s federal funds rate, by 25 basis points to 2.75% on September 2, 2026. It has also told banks to scrutinize the ongoing insurability of what they lend against. If a lender cuts loan-to-cost to 55%, the modeled project needs NZ$1,829,877 more equity than Scenario A.

Five. Don’t underwrite the statutory clock.

Non-notified resource consent applications maintain a 20-working-day statutory processing timeframe under the Resource Management Act, but the clock stops whenever the council asks for more information. Auckland reports about 15,000 resource consents per year, with 80% processed within statutory timeframes and 98% approved. But how councils handle information requests will soon shift dramatically if a property is exposed to any of the seven covered natural hazards, per planners at Davis Ogilvie.

Strategic Implications

The council applies the national matrix. The insurer applies its own model.

The insurer Tower says it prices earthquake, flood, sea surge, and landslide risk property by property, not by area averages. Since July 1, 2026, its hazard data has appeared in Westpac New Zealand’s banking app when you request an insurance quote.

Cotality sells a flood score for every address to lenders and insurers, but its product page publishes no model date and no methodology. The Natural Hazards Commission’s public portal lets anyone look up claims nationally, while its hazard maps cover only the Bay of Plenty region. The new national hazards policy asks everyone to rely on the best available information. Right now, that’s three private ratings and one statutory matrix, none of them reconciled.

Does a levee, or stopbank, make the question go away? No.

Ruth Feist of Hayson Knell, writing for Property Council New Zealand, the industry group for commercial property owners, says consent applications must include an assessment of residual risk and how to manage it. (Residual risk is what remains after the defense is built.) She adds that premiums in protected, or defended, areas will be affected. A site behind a defense still needs its own evidence.

The market hasn’t decided either. The same Cotality research that found the Mount Albert discount also found that flood-impacted Auckland zones grew 18.4% in value since 2020, against 13% in nearby buffer zones. Its chief data officer, Craig Dargusch, put it this way. Affordability wins today, but risk shapes tomorrow.

This tells me there’s an opportunity in the cost. The rating the council, lender, and insurer all trust will decide which sites are financeable. A developer who commissions the assessment first, designs the floor level in, and hands the lender and the insurer the same evidence the council saw is selling certainty, and certainty is scarce.

Takeaway

The new hazards rule isn’t the real risk. In our modeled scenario, complying with it costs about 7.4 percentage points of margin, and most of that is concrete, not consultants. The bigger risk is the exit. A flood rating can move the sale price more than the rule’s compliance costs combined.

On Thursday, we watched a city’s water supply become a credit rating. Today the question comes home to our own industry, in a place most of us never think of as climate exposure: a real estate firm’s own retirement plan.

Market Signal

On March 3, 2026, a former Cushman and Wakefield employee, Renee Kvek, filed a proposed class action lawsuit under the Employee Retirement Income Security Act (ERISA), the federal law governing retirement plans. It was filed in the Western District of Washington, in Seattle, before Judge John H. Chun.

The case is pending, and no court has ruled on the merits. Every claim about the plan, the fund, or anyone’s conduct is an allegation in the complaint or an argument in the defendants’ motion. We take no view on who should win.

The complaint alleges that the Cushman and Wakefield 401(k) plan held about $1.7 billion for 23,448 participants at the end of 2024, and that employees paid in nearly $115 million of their wages that year alone.

By contrast, the fund at the center of this case held just under $39 million, or about 2.3% of the total plan’s assets, and fewer than 4,000 participants held it. In other words, this is a small fund inside a big plan.

So why does it matter to anyone who manages, advises on, lends against, or insures commercial real estate (CRE)?

The plaintiff’s theory is that a firm that sells climate risk analysis to clients can’t ignore it when it comes to its own employees’ money. The price is the legal and reputational cost of a gap between what you sell and what you hold.

Case Study

The first allegation is performance.

The complaint alleges that the Westwood Quality SmallCap Fund returned -0.06% for the year to December 31, 2025, while the Russell 3000 Index, a broad US stock market benchmark, returned 17.15%. The complaint puts that shortfall at 17.21 percentage points. Over five years, it alleges a 6.57% return versus 13.15%.

The second allegation is fees.

A fund’s expense ratio is its annual fee as a share of the money invested, with the net figure reflecting any fee waivers. The complaint alleges the fund added its Ultra share class in 2021 with a gross expense ratio of 108 basis points and a net expense ratio of 79 basis points. The fund it replaced, the DFA Small Cap Value Fund from Dimensional Fund Advisors, charged 51 basis points, so that’s a step-up of 28 basis points.

The complaint calls 0.79% unreasonably high for a plan this size, against a 0.35% average for domestic equity funds in the largest plans, from 2019 benchmarking.

The third allegation is climate.

By the fourth quarter of 2025, the complaint says, the fund held 74.35% in sectors the Task Force on Climate-related Financial Disclosures (TCFD) identifies as climate vulnerable, against 32.73% for its benchmark. TCFD was an international body that disbanded in 2023 and set a widely used climate reporting framework. The complaint says the fund in question was 127% more exposed than the benchmark.

The fourth allegation is disclosure.

The Principles for Responsible Investment (PRI) is a United Nations-supported investor network. The complaint alleges that the fund manager’s 2020 PRI Transparency Report disclosed that its investment policy did not cover climate change. The report also said the manager did not run scenario analysis on climate-related risks. According to the complaint, the plan’s investment committee allegedly had that report when the fund went onto the menu in 2021.

What does the plaintiff want, beyond money?

According to the Sabin Center for Climate Change Law at Columbia Law School, the complaint asks the court to appoint a special master, an official who supervises a task on the court’s behalf. That official would oversee a revised investment policy statement with standards for climate competency and assessment of emerging risks.

In other words, it asks a court to write a climate standard into a CRE firm’s fiduciary document. To date, it’s relief sought, not relief granted.

In March, Cushman and Wakefield told ESG Dive, a trade publication on environmental, social, and governance (ESG) issues, that it has thoughtful processes in place that are designed to give plan participants a variety of prudent investment options. On May 7, 2026, the defendants filed a motion to dismiss, along with a motion to change venue (move the case to a different court) and a motion to strike the jury demand.

As the National Association of Plan Advisors reported, the defendants moved to dismiss, arguing the plaintiff lacked proper process and standing, meaning no legal right to bring the claim. Amy Roy of the law firm Ropes & Gray, who has no stake in the case, told Bloomberg Law in March that beyond the broad statements, the case seemed like a run-of-the-mill ERISA case about underperformance and excessive fees. In other words, in her view, it’s a fee-and-process case that uses climate language.

On July 23, 2026, Judge Chun granted the venue motion. Per Bloomberg Law, he reasoned that Illinois administers the plan, and about 6% of participants live in Illinois, compared with fewer than 2% in Washington. On August 11, 2026, the Northern District of Illinois docketed the case before Judge John Robert Blakey. As of this writing, I have not found a ruling on the motion to dismiss, though public dockets can lag.

Strategic Implications

Four drivers carry this case well beyond one plan.

Driver one is that your marketing might become the exhibit.

The complaint quotes Cushman and Wakefield telling clients they must fully understand the level and type of hazards an asset or portfolio faces, and that this requires a tactical response. The firm’s live Climate Risk Global Cities Outlook page promises to help clients understand and disclose their climate-related risks. That outlook covers 100 global cities and eight hazard types, projected to 2050 under a high-emissions scenario.

GRESB, a sustainability benchmarking organization that many real estate funds report to, lists Cushman & Wakefield among its global assessment partners, with climate risk assessment and resiliency as its primary service. In November 2025, the firm’s Portugal business announced that Fidelidade Property had hired it for climate risk mapping and building-resilience work aligned with European Union (EU) Taxonomy standards. The EU Taxonomy classifies which economic activities count as sustainable.

Most professionals, such as those in fiduciary roles or licensed professionals like insurance agents or lawyers, are ‘held to a higher standard’, meaning they know more than someone outside their profession and should act accordingly. So the more a firm earns from providing climate advice, the sharper any consistency test becomes. Legal risk depends not on whether it believes the science, but on whether its claims and holdings align.

Driver two is that federal rules are retreating, but the paper trail isn’t.

On May 29, 2026, the Securities and Exchange Commission (SEC) proposed rescinding its 2024 climate disclosure rules, which never took effect. Chairman Paul Atkins said, “SEC disclosure obligations should comply with the Commission’s statutory authority . . . [and] avoid the practical effect of dictating corporate behavior.” The Federal Register notice estimates annualized savings of about $4.9 billion per year for registrants over ten years. The comment period closed August 3, 2026, and the Department has taken no final action to date.

The Department of Labor’s replacement rule on fiduciary investment duties went to the White House regulatory office on June 30, 2026. PLANSPONSOR, a trade publication for retirement plan sponsors, reports it may revert to a standard based solely on risk-adjusted returns.

That cuts both ways. The defense can argue climate isn’t a permitted factor, while the plaintiff frames it as a financial one. For a CRE firm, the safe ground under either rule is written financial reasoning. A retreating mandate doesn’t remove what you’ve already published.

Driver three is that other markets are raising the detail bar, and your pitch book gets read against them.

Mirvac is an Australian real estate investment trust (REIT). Its fiscal 2026 annual report, approved on August 19, 2026, says its climate disclosures follow AASB S2, the Australian Accounting Standards Board’s climate standard, and the Corporations Act. The accounting firm PwC provided limited assurance over select environmental and social data covering the 12 months to June 30, 2026.

In Singapore, an MSCI study reported by The Straits Times found that 98% of Singapore-listed companies mention physical climate risk. Only 22% disclose in detail how it affects their business. The global disclosure rate was 27%. In other words, most companies name the risk without showing its effect, the same gap this lawsuit puts on trial.

Meanwhile, Singapore’s Accounting and Corporate Regulatory Authority (ACRA) is consulting on new sustainability disclosure standards until October 25, 2026, with the climate standard proposed as mandatory.

Driver four is that allocators can run the same test, and they’ve started to say so.

On September 17, 2026, the Net-Zero Asset Owner Alliance, a group of 85 asset owners convened by the United Nations (UN), published a call to action to private market managers that explicitly names real estate. One recommendation is to integrate physical risk and adaptation analysis into investment decisions, management, and resilience planning.

While the Alliance does not make this point, it seems reasonable to expect that a manager that fails a consistency test will face this question in a diligence questionnaire long before it faces a court.

Future Signal

The next decisive event is the Illinois ruling on the motion to dismiss. I anticipate that if the court lets any prudence claim proceed, copycat complaints will follow against advisory firms whose client marketing is louder on climate than their own plan menus. If it’s dismissed on standing, the consistency argument moves out of ERISA and into diligence questionnaires.

What would prove that wrong? It would take a ruling that a plan fiduciary has no duty to consider climate-related financial risk at all.

California’s Senate Bill (SB) 253 requires large companies to report their Scope 1 and 2 emissions, meaning direct emissions and those from the energy they buy. Under the California Air Resources Board’s proposed extension, the first reports are due November 10, 2026. Its sister law on climate risk reports, SB 261, has been blocked by the Ninth Circuit, the federal appeals court for the western states, since November 18, 2025, and no decision has come since argument on January 9, 2026. And Singapore’s consultation closes October 25, 2026.

The data vendors cut both ways too. MSCI, the index and analytics provider, closed its purchase of First Street, a physical climate risk modeler, on August 3, 2026. That put property-level modeling of more than 2.4 billion structures on its platform. Persefoni sells carbon accounting, and Workiva sells reporting software with audit trails. Those tools help a firm prove its climate statements match its data. They also make inconsistencies easier for a plaintiff or allocator to find.

Stakeholder Takeaway

For CRE managers, advisers, and REITs raising capital, put your client-facing climate statements next to your own plan menu, your balance sheet, and your sponsored funds. Then document the financial reasoning for any gap. You don’t need to accept climate science to do this.

For plan committees inside real estate firms, a plaintiff may now ask a court to rewrite your investment policy statement. Record in the minutes the reasoning behind every fund you add or keep, with fees and performance first.

For allocators and consultants, 85 asset owners' call to action gives you the questions. Ask managers to reconcile their climate marketing with their own holdings, in writing.

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

On Wednesday we read France’s CatNat surcharge as a price signal, an insurer telling the market what clay soil and dry summers cost, before any appraiser does. Today the signal comes from a different desk. In Corpus Christi, Texas, the price of dry weather showed up first in municipal bond ratings, and those ratings sit upstream of every industrial lease, tax bill, and loan in the metro.

The Moment

Just a few weeks ago, ahead of a utility bond sale of about $300 million, S&P Global Ratings took the Corpus Christi utility system off CreditWatch and affirmed it at A, with a negative outlook. The same day, September 15, 2026, Fitch affirmed it as A-minus and moved its outlook to ‘stable’. Bank of America Securities is the lead underwriter.

The last time this utility came to market, in June 2025, Fitch and S&P both rated that deal AA-minus, and for the first time, the City bought bond insurance to lift it to AA. Corpus Christi priced $296.87 million of senior lien utility bonds as ‘stable’. It drew more than $1.3 billion of orders from 53 institutional investors.

What happened during those fifteen months between June 2025 and September 2026 to drop the credit rating two notches lower at S&P and three notches lower at Fitch? It wasn’t a pension, a recession, or a bad audit. It nosedived because of water.

But this story isn’t that a city got downgraded. It’s the sequence. In just over a year, a water supply question became a cost-of-capital question. And if you had been looking, you might have seen it coming.

The Story

In the early hours of September 3, 2025, after a 13-hour meeting, the Corpus Christi City Council voted 6 to 3 to cancel the $1.2 billion contract for its Inner Harbor seawater desalination plant. This came amid severe water shortages and a prolonged drought in South Texas, when the city projected water demand would outpace supply by spring 2027.

Within weeks, Fitch and S&P both moved the utility’s “outlook” to negative. Moody’s had already opened a review in September. Outlooks are a polite warning.

Then, on December 11, 2025, Moody’s cut the general obligation limited tax and sales tax ratings - bonds backed by the city’s general taxing power, like property and sales taxes - to A1 from Aa2. For context, Aa2 and Aa3 represent high quality and very low credit risk, and A1 represents upper-medium grade and low credit risk. The city remained in investment-grade territory and was highly unlikely to default, but its financial cushion and risk profile weakened. Due to the environmental risk - low water supply - Moody’s downgraded the combined utility rating to A1 from Aa3 on approximately $2 billion of the city’s outstanding municipal debt.

The City’s press release said the rating agency highlighted the potential to curtail industrial operations, a key component of the regional economy. Industrial demand is more than half of the region’s water use. Hence, a water shortfall became a credit problem because refineries and chemical plants that buy the water anchor the tax base.

By April 2026, the city was projecting mandatory cuts of 25 percent for every customer if a Level 1 water emergency were declared. Moody’s put the city under review again that month.

On May 4, S&P lowered the utility from AA-minus to A, two notches, and put it on negative CreditWatch for three to six months. The City’s release says S&P pointed to acute drought risk and the possibility of a Level 1 water emergency later that year.

The Bond Buyer reported S&P also flagged $1.4 billion of additional debt needs over three years. S&P applied the same cut to Nueces River Authority and Lavaca Navidad River Authority debt tied to Lake Texana and the Mary Rhodes Pipeline, which brings in water.

On June 1, Fitch downgraded the utility three notches, from AA-minus to A-minus. In the City’s release, Fitch cited the system’s weakened revenue defensibility and the continued strain on its financial profile from acute water supply constraints. Fitch also cited industrial customer concentration as a factor limiting system improvement.

When a few customers dominate your revenue, a curtailment order cuts income at exactly the moment it protects supply.

Then it rained.

Late July floods lifted the combined level of Choke Canyon and Lake Corpus Christi to 26.2 percent, and the projected water emergency moved from September 2027 to September 2028. By September 1, the City’s reservoirs were at 48 percent, up from 15 percent six months earlier. On July 1, Moody’s confirmed both A1 ratings with a negative outlook and a 15- to 18-month window to resolve it.

The project didn’t go away. On June 30, 2026, the council voted 5 to 4 against applying for up to $120 million of federal desalination grants for it. Then, on September 1, 2026, the council voted 5 to 3 to reject the Inner Harbor desalination plant a second time. (Note that this project is different from the Harbor Island active project.) The facility carried a preliminary guaranteed maximum price of $978.8 million and was projected to supply 30 million gallons daily, roughly one-third of the city’s water demand.

According to a city memo reported by The Bond Buyer, formally terminating this long-term supply project not only poses a structural credit risk that may trigger negative action from rating agencies, but also forces the city to resolve how to manage or defease $235 million in outstanding state-financed debt already issued for the project.

Structural Forces

Four forces turn a Texas water story into an underwriting problem anywhere.

Force one: industrial concentration cuts both ways.

The same companies that make the tax base valuable make the utility fragile. Corpus Christi is a major energy export gateway. The port reported 66.0 million tons of crude oil moved in the first half of 2026 alone. Those customers anchor the port, the supply chain, and the warehouse demand behind it. They also drink the water.

Force two: water is being repriced for industry, and industry pays first.

Back in 2023, the Corpus Christi council voted 8 to 1 to raise large-volume rates. One example of that vote’s impact: Valero’s annual water bill went from $9 million to $18 million. In July 2026, the council gave first-reading approval to new rates effective January 1, 2027. Those rate increases sit alongside planned utility borrowing of $292 million in fiscal 2027, $428 million in fiscal 2028, and $364.5 million in fiscal 2029.

In most industrial leases, water and sewer charges flow through to the tenant. That’s an occupancy cost tenants compare across metros at renewal.

Force three: the city’s credit is the tax base’s credit.

Moody’s cut the general obligation rating to A1. Fitch and S&P still rate the city’s general obligation debt AA, with negative outlooks. One of the three agencies moved the tax-backed rating. When the city sold $115 million of general improvement bonds in June 2026, it priced 85 basis points below the rate it had budgeted.

In November 2024, Breckinridge Capital Advisors wrote that only 10 percent of the broad-market Bloomberg Municipal Bond Index faces high physical climate risk, on data it attributes to Intercontinental Exchange (ICE), a third-party provider of climate risk data and analytics. Further, Breckinridge wrote that municipal credit spreads remain insensitive to climate risk in any measurable way.

Keep in mind, a rating is a credit opinion. A spread is a price. In Corpus Christi, the opinion moved three times in six months while the broad market shows no measurable price penalty. If you’re waiting for the spread to tell you, you are reading the slower instrument.

Force four: state capital is rationed, even as it grows.

In April 2026, the Texas Water Development Board received 27 applications for its main low-cost water financing program and could invite only the ten highest-ranked. The Harbor Island desalination project, the private plant Corpus Christi is now counting on, ranked eleventh. It didn’t make the cut.

In July 2026, the board adopted a state water plan carrying a $174 billion price tag over 50 years.

The Next Chapter

So what replaces the plant they rejected?

A plant that is only half private. The Nueces River Authority picked IDE Technologies in May 2026 as development partner for a seawater plant at Harbor Island. It would produce about 100 million gallons per day to start, with first water to Corpus Christi targeted for December 2029.

The total cost is roughly $6.4 billion, split in two. Private partners would finance and run the $3.2 billion plant. The other $3.2 billion is the public share: a pipeline network carrying water up to 200 miles inland, and that part is in trouble.

In July 2026, KRIS 6, the Corpus Christi NBC station, reported that design work on the pipeline had halted and that the river authority could run out of desalination money by the end of August. The state then put in $7 million for pipeline planning, and on September 24, 2026, the state’s environmental regulator approved the plant’s offshore discharge permit.

But no construction has started, no federal money is committed, three reservation contracts lapsed without renewal, and the executive director who championed the project retires at the end of October.

Cities that reserve capacity will be asked to sign take-or-pay contracts. Corpus Christi already paid $2.7 million in October 2025 to reserve about 50 million gallons per day. A take-or-pay contract for water is a fixed obligation on the utility’s income statement whether or not the rain comes back. It’s the same trade a commercial tenant makes signing a long lease on space they might not need. And the state money that would have cheapened it went to ten other projects this year.

Back in January 2020, a startup called risQ launched municipal-bond climate analytics as ICE Climate Risk. Intercontinental Exchange bought the company in December 2021, and its co-founder, Evan Kodra, was its chief executive at the time.

S&P Global Sustainable1 launched its own municipal dataset in April 2024, covering more than 3,100 US counties and 47,000 general obligation bond issues across nine hazards, including water stress and drought.

The aggregate picture should get a credit committee’s attention. In October 2025, Grist published ICE Data Services figures for municipal debt by climate risk category as of 2040. Drought accounted for $790 billion. Hurricanes, floods, and wildfires together accounted for $700 billion.

Those aren’t loss figures. That represents debt needed to face each hazard, and a bond can sit in more than one bucket. It is an exposure map, not a default forecast.

Over the next 12 to 24 months, expect the agencies to judge Corpus Christi on execution such as groundwater, reuse, and signed take-or-pay contracts, rather than on rainfall. S&P has already said it could lower the rating if the utility doesn’t diversify supply over the next two years. Expect lenders on Coastal Bend industrial assets to start asking for tenant water intensity and the water clause in each lease.

And expect the spread to stay flat for a while longer. The rating moves first.

The Strategic Question

If your industrial portfolio sits in a metro whose water utility has lost its AA rating, are you underwriting the tenant, or the tenant’s water?

I suggest you evaluate the following:

First, list which tenants would face a curtailment order, and whether the lease lets them abate or exit. In Corpus Christi, the number is already written down. Under the emergency ordinance the council adopted in June 2026, a Level 1 emergency cuts every customer class by 25 percent, with surcharges of $4.00 and $8.00 per 1,000 gallons over allocation and baseline.

Second, treat utility and general obligation ratings as leading indicators in your credit memo, the way you’d treat an anchor tenant’s credit. Three agencies moved this city inside six months, and every one of those actions was public the week it happened.

Third, ask who pays for new supply. Here it’s large-volume users, through rates set out to 2036, and those costs reach industrial occupiers first.

Rain moved the emergency to 2028, and the ratings stopped falling. But the buyer of your asset in 2028 will read the same rating reports you can read today.

On Monday, the European Central Bank showed us Eurozone buyers marking down high-risk offices in the sale price itself. Today that repricing arrives as a bill. France charges every property policy a statutory natural catastrophe (CatNat) surcharge, and that surcharge went up. The question for an underwriter isn’t what it costs. It’s what the increase tells you.

Market Signal

Every French property damage policy, household and business alike, carries a compulsory CatNat surcharge based on article A125-2 of the insurance code.

The French Parliament officially established the compulsory CatNat surcharge (or national natural disaster compensation scheme) on July 13, 1982, following disastrous national floods the previous year.

On January 1, 2025, the rate for that mandatory coverage rose from 12 to 20 percent of the property damage premium, applying to all contracts concluded or renewed from that date. This added €1.2 billion per year of coverage capacity.

One rate exists for all perils, including droughts, floods, earthquakes, cyclones, and land movement. France has no subsidence-only surcharge. Because the same 20 percent lands on every policy in the country, it tells you nothing about your building.

But instead of floods, drought is now the primary driver of the bill. CCR, the state-backed reinsurer behind the regime, reports in its Bilan (balance sheets) for 1982 to 2025 that drought accounts for 41.2 percent of cumulative non-motor CatNat losses, second only to flood at 50.4 percent.

Banque des Territoires, reporting on CCR in June 2026, puts drought at 53.1 percent of losses over the last ten years, and records 2022 as the costliest year, close to €3.9 billion of claims, with more than 95 percent of it drought-related.

For 2025, CCR estimates insured drought damage of €770 million to €1 billion. Of €3.71 billion of Cat Nat premiums that year, €1.54 billion came from businesses, representing 44.3 percent once motor is stripped out.

The first strictly uniform, legally binding nationwide RGA (the French-language version of the clay shrink-swell abbreviation) exposure map was created on July 22, 2020. Almost exactly one year after the 20% surcharge increase took effect, the first major overhaul to that clay shrink-swell exposure map since 2020 was imposed on January 9, 2026. It took effect on July 1, 2026.

If you aren’t familiar with the soil type, clay-rich soil shrinks when it dries out. Conversely, when it gets wet, it swells. Think back to pottery class - or Silly Putty that you failed to put away. This weather-driven soil movement is a leading cause of structural damage to buildings in France.

Medium to strong exposure now covers 55 percent of mainland France, up from 48 percent on the 2020 map, based on 446,000 claims from 1989 to 2022. That’s 12.1 million houses in the exposed zones. Centre-Val de Loire went to 90 percent of its territory, up from 82 percent. Remember that data point because we’re about to buy a warehouse there.

Deal Scenario

Let’s look at a modeled scenario to show how you might run your own numbers on a deal.

A 40,000-square-meter single-let logistics warehouse near Orléans, in Centre-Val de Loire. Rent is €50 per square meter per year, anchored on CBRE, which puts new warehouses in the Orléans, Blois and Tours market at €50 to €56 for the fourth quarter of 2025.

BNP Paribas Real Estate’s first-quarter 2026 chart reads €40 prime for Orléans. Assume landlord non-recoverable costs are €100,000. That yields rental income of €2,000,000 and NOI of €1,900,000.

The exit yield in our modeled scenario is 5.50 percent, within the field bounds and not solved for. At 5.50 percent, the value is €34,545,455. Debt is €19 million, interest-only at 4.5 percent, so €855,000 of debt service per year. In our modeled scenario, that’s a 55.0 percent loan-to-value and a debt service coverage ratio of 2.22 times.

JLL puts prime French warehouse yields at 4.90 percent in the second quarter of 2026. Cushman and Wakefield says leased secondary assets trade above 6 percent. A regional box is neither.

The first shock, then, is the premium.

The base property damage premium is assumed at €60,000, since nobody publishes a rate for large warehouses. At the old 12 percent, the surcharge was €7,200. At 20 percent, it’s €12,000. So the statutory step is €4,800 per year, which, capitalized at 5.50 percent, is €87,273 of value, or 0.25 percent of the asset. Noise.

Shock two is the renewal.

Lift the base premium 25 percent after the asset lands in a strong zone, and you pay €90,000 against €67,200 before, up €22,800 per year. Almost all of it is market, not statute.

Shock three is the repair nobody else pays for.

Assume a slab and foundation repair of €1.5 million at a 2 percent annual probability. That 2 percent is a deliberately harsh stress. If a drought recognition order is issued, CatNat pays, but the owner keeps the professional deductible, 10 percent of the damage with a floor of €3,050. In this model, that’s €150,000.

With no order, the owner pays the whole €1.5 million. At a 60 percent chance of recognition, the expected cost is €13,800 per year. At a 0.5 percent probability, the worst-case scenario is 5.67 percent, not 6.19 percent.

The landlord covers that repair cost. Structural work under Article 606 of the Civil Code, such as frame, roof, load-bearing walls, and weatherproofing, can’t be recharged to the tenant, whatever the lease says.

Our model shows three possible outcomes for a warehouse that is remapped into a high-risk climate zone:

Case A. Insurance is recharged to the tenant and the landlord holds the repair reserve. Net operating income is €1,886,200, and value is €34,294,545, down 0.73 percent.

Case B. Insurance is not recharged because the lease is silent or the box is empty. NOI falls to €1,863,400 because the landlord can’t pass a €22,800 annual insurance premium increase on to the tenant. Consequently, the property’s asset value drops by 1.93 percent to €33,880,000 when capitalized at the standard 5.50 percent rate, erasing €665,455 in equity compared to the baseline scenario.

Case C: Case B plus a 25 basis point widening of the exit yield, because buyers have seen the same map. At 5.75 percent, it’s €32,406,957, down €2,138,498, or 6.19 percent, with coverage at 2.18 times and loan-to-value at 58.6 percent.

Summarizing, the statutory surcharge moved value by 0.25 percent. The yield widening moved it by 4.26 percent on its own, which is €1,473,043.

For an insurance bill to do that much damage, it would have to rise €81,017 per year.

The premium is not the cost.

The premium is the evidence you use to set the yield.

And the input that hurts most isn’t clay. Run it at BNP’s €40 of rent instead of CBRE’s €50, and Case C value is €25,450,435, coverage 1.71 times, loan-to-value 74.7 percent.

That’s the covenant conversation.

Underwriting Analysis

So here are five tests to run before you price the exit.

One. Recognition history. CatNat pays for drought damage only after an interministerial order recognizes the municipality, and since January 1, 2023, a professional has 30 days from publication to declare.

Over a long enough window, it is near universal. The brokers’ body PLANETE CSCA reports that 99 percent of local administrative districts, known in France as communes, have been recognized at least once since 1982, for some peril. So the question is how often, and how fast?

The answer? Slow!

For the 2025 drought, CCR counted 345 communes recognized as of May 26, 2026, with 22 percent of requests approved. For 2022, once the campaign had run its course, 5,010 communes were recognized, with 739 refused, representing about 87 percent.

Two. Map zone. Pull the parcel against the 2026 clay map, and be precise about what that map legally does. It binds promises of sale on buildable, undeveloped land and individual house-construction contracts. For a warehouse, it’s free public information. Centre-Val de Loire moved to 90 percent from 82 percent, Bourgogne-Franche-Comté to 74 percent from 58 percent. The state re-rated an asset that changed zone, whether or not its premium has caught up.

Three. Separate the statute from the market. The CatNat layer is fixed by law. The market layer is falling. Marsh reports global commercial rates down 6 percent in the second quarter of 2026, property down 12 percent, and Europe down 9 percent. The French brokers’ body, reporting AMRAE’s 2026 study, says cuts can reach up to 20 percent depending on the account. So if your base premium or deductible rises at renewal while the market is cutting, that is an underwriter telling you something specific about your building.

Four. Read the lease for who pays what. Insurance premiums pass to the tenant only where the lease expressly provides for it. Article 606 structural work never passes through.

Be aware that an anti-negligence penalty is designed to pressure local town halls into taking climate risks seriously. If a town repeatedly suffers natural disasters but its local government refuses to implement an official Risk Prevention Plan (Plan de Prévention des Risques or PPR), the state forces property owners to pay exponentially higher out-of-pocket deductibles for every subsequent disaster claim.

In a commune with no risk prevention plan, that 10 percent deductible doubles at the third order recognizing the catastrophe, triples at the fourth, quadruples after that. In our modeled scenario, 20 percent moves the Case C loss to 6.28 percent and 40 percent takes it to 6.46 percent. While that seems small, it wires Test One straight into cost.

Five. Watch the regime’s own balance sheet. The rate can move again. CCR says 2025 let it begin rebuilding reserves, aiming to withstand a one-in-forty-year event by 2035. Its own 2050 study projects geotechnical drought’s average annual cost rising 83 percent from the hazard alone, €606 million per year, and 103 percent with exposure growth. Those are CCR’s modeled numbers.

The Barusseau bill on adaptation passed the National Assembly at first reading on April 8, 2026. It is PROPOSED, not law, with Senate debate set for October 19, 2026. It would allow, by decree, premium modulation for professional property worth more than €20 million in risk prevention plan zones.

Our modeled warehouse is worth more than that.

Strategic Implications

On September 7, 2025, the reinsurance intermediary Howden Re partnered with the climate modeling firm Reask to combine climate data and subsidence modeling with local meteorological institute data for the United Kingdom and France. Jamie Rodney is Reask’s chief executive, and Tim Edwards is Howden Re’s head of international analytics. Reask’s co-founders, Thomas Loridan and Nicolas Bruneau, presented the work in Paris in December 2025.

The method is the part an investor can copy. They use the Soil Water Index from ERA5, a public monthly reanalysis dataset, which lets them project a drought year as early as October. Their preliminary read said about 11,500 municipalities could meet the drought criteria for 2025, and that recognitions would have run about 32 percent lower had the year followed the 2018 spatial pattern.

Those are their own preliminary modeled numbers. The data is free, monthly, and months ahead of the paperwork. The state hands you the rest for nothing. CCR publishes claims by peril and premiums by payer. Géorisques publishes the clay map.

Meanwhile, Descartes Underwriting, a Paris parametric insurer founded in 2019, writes drought but not subsidence. A parametric trigger on a soil moisture index could fund the deductible and the no-recognition case, independently of any order.

Know, however, that the costliest insured event, $1.3B insured, across Europe, the Middle East and Africa in 2025 wasn’t drought at all. It was a convective storm outbreak on June 25 and 26. French insurers carried that, and rates still fell.

Takeaway

Read the premium before you price the asset.

The 20 percent surcharge is not the risk. It’s the state telling you the drought bill is structural.

The risk sits in the deductible, in the recognition gap, and in article 606. And that risk shows up in the exit yield.

The surcharge step — the CatNat rate on property damage contracts raised from 12 to 20 percent, and on motor theft and fire premiums from 6 to 9 percent, from January 1, 2025, adding about €1.2 billion per year of capacity. Article A125-2 of the insurance code (Légifrance) carries the rates.

One rate for all perils. It is the same on every policy and says nothing about any single building.

The regime’s origin — Loi n° 82-600 of July 13, 1982, created the regime after the winter 1981 floods in the Saône, Rhône and Garonne valleys.

On Friday, in Johor, a state water test decided which data centers get built. That was a permit. Today we move from permits to prices. The question is whether office buyers in the EU have been repricing climate risk on their own, deal by deal. The European Central Bank went and measured it.

Market Signal

Three authors at the European Central Bank, Kai Foerster, Ellen Ryan and Benedikt Scheid, published Working Paper 3059 in May 2025. They took 24,386 office sales across the Eurozone, plus Bulgaria, and matched each one to a physical climate risk score. These are large office deals, mostly €10 million or more. The deals they examined ran from 2007 to 2023, but the price results stopped in 2022.

The headline said the discount on a high-risk building increased by 24 percentage points between 2007 and 2022. But what does that actually reflect?

High-risk offices actually sold at a small premium in 2007, once you control for location and the local economy. By 2022, that had turned into a discount of about 13 points, roughly 12 percent below comparable offices. So the historical story is a swing from a premium to a discount.

And it wasn’t a straight line. The discount first became consistently significant in 2012. It was deepest in 2013. It was back close to zero in 2021, and it opened up again in 2022. Why is this even relevant?

What matters for a lender is how it happened. About a quarter of the offices sold each year had a high risk score. Buyers didn’t walk away. They just paid less.

Case Study

Let’s open the study up, because the data behind it is today’s fintech story.

Robert M. White, Jr. founded Real Capital Analytics. Later, Emilie Mazzacurati founded Four Twenty Seven, a Berkeley, California climate data firm. She named it after 427 million tonnes of carbon dioxide, California’s 1990 emissions level, which the state had set as its target for 2020. In 2019, Moody’s took a majority stake in Four Twenty Seven. Then, MSCI bought Real Capital Analytics in 2021 for $ 950 million. Finally, in 2023, the reinsurer Swiss Re bought Fathom, a flood modeler in Bristol whose data builds the flood part of those hazard scores.

Deal prices from one company, hazard scores from another, flood maps from a third. That stack made this measurement possible.

Four Twenty Seven scores six hazards: floods, heat stress, earthquakes, water stress, sea level rise, and wildfires. The scores are an annual snapshot for a postal code or city. When measuring specific hazards like river flooding, heat stress, or wildfires, the working paper group evaluated regions based on their maximum risk levels. On that measure, the paper finds rising discounts for flooding where the worst score anywhere in the region is Red Flag, and for heat stress and wildfire where it is High or Red Flag. The authors read the difference as geography. Heat stress covers a whole region, so a regional average catches it. Flooding and wildfire are local, so an average washes them out and only the worst score shows the damage. The flood result is the smallest and the least certain of the ones they report. But it is there, and it is there precisely where the worst score sits.

Their model compares office buildings sold in the same year and the same country. It accounts for whether the office is in the central business district, as well as regional income, growth, house prices, and population. The price it explains is price per square foot, so scale is already netted out. What it doesn’t account for is the building itself, its age or its condition. So in this result, comparable means a comparable location, not a comparable building.

The paper does look at building age, but in a separate test and for a different risk. On 15,184 transactions, it uses age and time since last renovation as a stand-in for energy efficiency, and finds the spread between new and old buildings widened by 18 percentage points. That’s transition risk, not storm risk. From 2018, activity shifted toward newer buildings.

In the final two years of data examined in the study, 2021 and 2022, the working paper reviewed hazards individually. They found heat stress and sea level rise both carried a significant extra discount during that timeframe. They used earthquake risk as a control. It showed no rising discount, unlike other hazards more directly related to climate risk. Water stress showed no discount at all, in any year from 2007 to 2022.

Physical risk showed up in price. Transition risk showed up in who could find a buyer.

Who were those buyers? Investment funds represented just under 60 percent, while about 20 percent were companies. About ten percent of buyers were pension funds and insurers.

Institutions are on the buy side of nearly every deal in this sample, so their pricing is what sets the comparables for everyone else.

Strategic Implications

The paper’s data stopped in 2022. This is where the market stands in 2025 and 2026.

The market is coming back, slowly. CBRE counted €59.1 billion in European real estate investment in the second quarter of 2026, up 10 percent year over year.

MSCI’s own Real Capital Analytics data shows €10.5 billion of European office deals in the first quarter, down 3 percent.

The European Central Bank’s May Financial Stability Review says commercial property prices point to a return to positive annual growth. But Eurozone deal volumes are still about 60 percent below their 2019 peak by value, and the Bank says financial stability vulnerabilities remain elevated.

As deals return, they’ll clear against whatever discount buyers now apply, except there is no current measure of that discount. But factors are driving it.

Driver one is the exit yield. In our modeled scenario, apply the 2022 discount of about 13 points to an office. If rent holds, a lower price is a higher yield. An assumed 5 percent exit yield becomes about 5.69 percent, some 69 basis points wider. On an office worth an assumed €50 million, that’s about €6.1 million of value. For context, Savills puts the average European prime office yield at 4.9 percent in the second quarter of 2026. There, the same step yields 5.58 percent, for illustration.

Driver two is liquidity. In the baseline, high-risk offices kept selling. The cost came through price, not through a longer marketing period. For a seller, that’s a pricing question, not a timing one.

Driver three is the lender. The European Banking Authority’s guidelines on managing ESG risks have applied since January 11, 2026, to every bank except small, non-complex ones. They list, among the things banks should monitor, exposures and collateral in high-flood-risk, water-stressed, or wildfire-risk areas. And in the ECB’s July lending survey, banks named physical risk to real estate as the dominant climate reason for tightening credit on housing loans. That’s housing, not commercial property, but the direction is clear.

Driver four is the policy-maker. RICS published the fourth edition of its global standard on ESG and sustainability in commercial property valuation on January 28, 2026. It took effect on April 30. It provides guidance on how to assess ESG where it’s significant to value, and it adds an EU section. It doesn’t name flood or physical risk.

Driver five is the hazard itself. The current evidence here is strong. In late June 2026, Aon reports that 17 European countries broke their all-time June temperature records, with more than 1,000 deaths across France, the UK, Spain and Belgium. Swiss Re says Europe now averages 21 to 26 days per year at 30 degrees Celsius or more, against 10 to 17 days in the 1950s. The European Environment Agency puts EU weather and climate losses at €822 billion from 1980 to 2024, and floods were 47 percent of that. So floods drive losses, even though they didn’t clearly drive office prices in this study.

Insurance cuts both ways right now. Marsh says commercial property insurance rates in Europe fell 9 percent in the second quarter of 2026. That’s a soft market. But Munich Re and JLL report that premiums for office buildings in Germany have risen 8 to 12 percent per year on average since 2018.

Future Signal

Back to the founders, and where they are now. Emilie Mazzacurati left Moody’s in 2022 and is now founding partner of Tailwind Futures. MSCI still publishes the Real Capital Analytics deal data. And in January, Fathom said Swiss Re had built its flood data into Swiss Re’s own flood catastrophe model. The insurer that owns the flood model now uses it in its own view of flood risk. The data that measured this discount now sits inside the firms that price risk.

The wider market keeps building.

In August, Climate X partnered with the consultancy IBD Sustain to take physical-risk data into real estate advisory work. Deepki bought three firms and says it now monitors more than €4 trillion of client assets. Notably, the voluntary net-zero pledges behind the 2023 new-building premium have since weakened, while the building rules for offices have not.

As Eurozone office volumes recover, expect hazard scores to move from the ESG appendix into the valuation report and the lender’s credit file. That directional forecast would be discredited if a new ECB or MSCI reading after 2022 shows the discount flat or gone. The baseline for that test is the 2022 figure.

Stakeholder Takeaway

If you are an investor or developer, pull the hazard score for every office you plan to sell, and test the exit against a discount, not a flat market yield.

If you are a lender, ask whether the appraisal reflects hazard before you size the loan.

If you are an insurer, the data behind this discount is the data your pricing competes with.

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

On Wednesday we put a Vancouver rental building through a lender’s flood test, and watched one insurance renewal shrink a loan. Today the water problem runs the other way. In Johor, in southern Malaysia, just across the causeway from Singapore, there isn’t enough of it. And the state has started screening which data centers get approved.

The Moment

On August 28, 2026, Malaysia’s national water regulator, SPAN, reported on the 49 major dams that feed the treatment plants of Peninsular Malaysia and Labuan. Thirty-seven were at normal levels. Nine were at warning level, six in Johor, and one was critical.

SPAN warned that supply disruptions could worsen if levels kept falling. All the treatment plants are still running, and nobody’s taps are dry, so the warning is data-driven, not panic-driven.

Three weeks later, driven by the data center boom, the Malaysian broker RHB Research valued Ranhill Utilities, the listed parent of Johor’s water operator. RHB counts about 8.5 gigawatts of incoming data center capacity in Johor, on top of 1.1 gigawatts already running, which means water is no longer a utility line item in the operating budget. It’s an approval condition.

For investors, lenders and insurers, that turns a water contract into something that looks like a closing condition.

The Story

The state hasn’t frozen data center approvals. It screens them.

In the November 2025 sitting of the Johor state assembly, housing and local government chairman Mohd Jafni Md Shukor said Johor would no longer approve Tier 1 and Tier 2 data centers. That’s how both The Star and Bloomberg reported it.

In March, 2026, the Menteri Besar, the state’s chief minister, put it on the record through Bernama, Malaysia’s official news agency. The committee will only approve Tier 3 and Tier 4 data center developments that use air-cooling technology.

A word for data center readers. Tier in this context refers to the industry’s reliability grade, Tier 1 to Tier 4, which measures redundancy and uptime. It isn’t a water tier. The state is using the reliability label as a screen, and tying it to water used for cooling.

The state’s own written answer to that same assembly sitting sets out the rest. It’s translated from Malay so that some nuance may be lost.

• The approving committee considers first the applications that don’t use the public supply from Ranhill SAJ.

• It makes alternative water a condition of approval.

• It requires water-use efficiency below 1.8.

• It approves small volumes of water, with 2031 as the year of use.

• And it follows SPAN’s water supply guideline, in force since September 1, 2025, which puts reclaimed water for data center cooling ahead of treated drinking water.

There was also talk of a pause. In November 2025, the South China Morning Post reported that investors had been asked to hold off water-cooled expansion for at least 18 months, until mid-2027. But in February, the federal trade ministry, MITI, told Parliament that as of January 2026, no data center investment in Malaysia had been deferred because of water.

Meanwhile, approvals continue.

In May, the state assembly heard that 5,628 megawatts had been approved across 28 data center projects, and that the twenty centers already running were using about 920 megawatts. That’s definitely not a freeze. But it is a screen, and one that’s getting tighter.

In February, households in Benut, Pontian and Simpang Renggam were moved to scheduled water supply. The state’s works chairman said the cause was drought, and that no data center takes water in those areas. But even a correct denial costs something. Every dry spell now puts data centers in the headlines, and the approving committee answers to the same voters.

Structural Forces

Four forces turn this into an underwriting consideration.

First, water now has its own price.

Since August 2025, Johor charges data centers a dedicated rate of RM5.33 per cubic meter. That’s about 50 percent above the old top commercial rate of RM3.55. At the same time, the top rate for every large commercial user rose by 49 percent to RM5.30. So data centers pay three sen more than everyone else at the new rate.

The category is new. The price is mostly the market repricing of water for everyone.

What does that cost an existing plant? In our modeled scenario, take a 100-megawatt data center that still cools with mains water. Mains water is the municipal drinking supply, piped from the local utility and used to cool high-heat servers. The Straits Times figure for that design is about 4.16 million liters per day. At RM5.33, that’s about RM8.1 million per year for water. That’s a legacy design Johor would no longer approve, so it’s the exposure only an existing owner carries.

Second, the approval gate is a compliance test.

By November 2024, officials reported rejecting almost 30 percent of applications for weak sustainability practices. For land held for data centers, the entitlement now depends on a water test. That feeds straight into land and resale value.

Other places are writing similar tests.

For example, New York’s Executive Order 62, signed in July, pauses incomplete state environmental applications for data centers of 50 megawatts or more. Pennsylvania’s order in August requires operators to report annual water use and peak-day demand, and sets strict conservation requirements for developers who want state support.

Third, headroom is thin where the servers are. By headroom, I mean the gap between what the treatment plants can produce and what the state is already using. In Greater Johor Bahru and Kulai, the state told its assembly in September 2025 that design capacity was 1,274.1 million liters per day and average production had reached 1,129.1 million liters per day. That’s a reserve margin of 11.4 percent.

Statewide, the margin is wider, 14.5 percent in the same state data and 12.8 percent in RHB’s estimate. The zone is what matters for data centers.

Against that margin, the federal minister told Parliament that Johor’s data center water demand is projected to reach 384 million liters per day by 2030. RHB’s ceiling may be about 400, based on the old water-cooled figure scaled across every megawatt.

And fourth, public money is years behind. The state has 38 water projects worth RM15.3 billion planned out to 2050. Johor and the federal government are putting about RM5 billion into three reservoirs and three treatment plants. None of that is running yet.

Until it is, a site’s water contract is the scarce thing.

The Next Chapter

So where’s the capital?

This is where the fintech and finance stories come in.

Robin Khuda founded AirTrunk, an Asia-Pacific data center platform, and still runs it as CEO. Blackstone and the Canada Pension Plan Investment Board, CPP Investments, bought it in December 2024, valuing the company at over A$24 billion.

In August 2025, AirTrunk closed a sustainability-linked refinancing round, backed by more than 60 banks and financiers. It covers assets in Australia, Hong Kong, Malaysia and Singapore.

AirTrunk puts the refinancing at about A$15.76 billion excluding Japan, 100 percent of it ESG-linked, and total ESG-linked debt at over A$17.75 billion including Japan. Khuda’s point was that linking the whole global financing structure to sustainability is what a long-term commitment to scaling responsibly looks like.

But let’s look at what Blackstone and CPP Investments actually bought. Not buildings. Growth. And growth here meets the utility before it meets the capital.

In May, 2026, Blackstone used a sophisticated risk-mitigation strategy, bringing in the International Finance Corporation (IFC - part of the World Bank Group) for a US$175 million debt-and-equity injection into AirTrunk’s Johor campuses. IFC’s disclosures verify that at full capacity, the facilities are projected to consume 910 million liters of water annually. Its action plan requires the project to upgrade its monitoring of natural resource consumption to IFC standards, which cover water. That is a monitoring condition, not a cap. The lender bought visibility.

Now, the part that ties this month together, because here the financing writes the engineering spec. AirTrunk published a Green Financing Framework in April 2025. It names three eligible categories for green money, and one of them is water efficiency. For a new data center in a warm climate like Johor, it sets an annual PUE target of 1.4.

PUE stands for Power Usage Effectiveness and measures a data center’s energy efficiency. The global average is 1.52, per the Uptime Institute. Meanwhile, Germany’s Energy Efficiency Act mandates new builds achieve a PUE of 1.2 or lower.

In February 2025, AirTrunk announced JHB2, its second Johor campus, at a design PUE of 1.25 using liquid cooling. Publicly available data from Johor and AirTrunk vary. It seems the actual PUE ranges somewhere between 1.25 (the target) and 1.4 (the green loan threshold).

Here’s the gap a lender should ask about. AirTrunk’s portfolio water usage effectiveness for FY25 is 0.89 liters per kilowatt-hour, comfortably inside Johor’s 1.8. But the first Johor campus is excluded from that figure, because the report counts only sites with twelve months of operation, and the framework reports water at portfolio level. So there is no published Johor water number yet. The first one arrives in the FY26 report.

One more thing worth your attention. AirTrunk’s own FY25 table sorts water withdrawal by water stress level. Melbourne and Sydney sit in the high band. Johor sits in the medium-high or lower band, grouped with Hong Kong, Osaka, Singapore and Tokyo. That is the operator’s classification, while the state rations supply and screens approvals. Underwrite the asset, and you underwrite that disagreement.

And yet outliers still exist, at least on transparency. In August, STT GDC, the Singapore operator, secured up to US$1.37 billion of green financing for a campus of up to 166 megawatts in Iskandar Puteri, Johor. The only water fact in the announcement is a 41.2 percent improvement in company-wide water-use efficiency since 2020. No water condition is disclosed. That doesn’t mean none exists, because the loan agreement isn’t public. But the state screens every approval on water, and the biggest Johor green loan in 2026 says nothing about it.

Meanwhile insurers are watching the soaring cost of risk transfer. The Swiss Re Institute warns that if cities cut water supply in a drought, a data center may have to shift cooling modes or temporarily shut down. It expects global data center insurance premiums to grow from US$10.6 billion to US$24.2 billion by 2030. In other words, it will more than double within the next four years.

One might read the news and think data centers are a tech play with a PR problem. But from an operator’s side, the considerations are a much bigger balancing act before even considering the end product. Site prep and building maintenance, local and regional policy restrictions, lender targets and reporting transparency, and insurance considerations all factor in, while you also face the possibility of not having enough power to run or water to cool.

A data center stops being valued on megawatts and starts being valued on its water contract. Sites with a signed non-drinking, industrial water supply should trade above sites without one, and lenders should treat that contract the way they treat a grid connection, as a condition of drawdown. The upside is the treatment plants landing on time. The downside is a dry year arriving first.

The Strategic Question

So here’s the question for you. If you own, finance, or insure a Johor data center, or land zoned for one, can you show the committee, the lender, and the next buyer four things?

• A signed source of non-drinking water?

• A water usage effectiveness below 1.8?

• A PUE in alignment with local targets?

• And an operating budget that holds at RM5.33 per cubic meter?

If you can’t, the risk isn’t a flood or a fire. It’s an approval you can’t get, or a campus that can’t expand.

And if you invest outside Malaysia, the question travels. In every market where you underwrite data centers, who decides how much water the site gets, and on what test?

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

Canada’s bank regulator ran flood maps across the country’s lenders and published its findings. Over 250 institutions took part, covering CA$904 billion in mortgage and real estate assets and CA$3 trillion in insured property values, about 40 percent of the mortgages in Canada.

Only 12 percent of deposit-taking institutions require or collect information on flood insurance coverage for the properties they lend against. That is the single most useful sentence in the report for a borrower.

It means the file your lender is missing is one you can hand it, before the credit committee prices the gap as unknown.

Market Signal

In September 2025, OSFI, Canada’s bank regulator, and Quebec’s regulator, the AMF, published the results of a standardized climate scenario exercise. The flood module covered eleven urban regions from Vancouver to Fredericton. Toronto was not one of them.

Two findings matter to a borrower. The first is the collection gap: 12 percent of deposit-taking institutions require or collect flood insurance information on the properties they lend against, in a country where only 40 percent of homeowners buy optional flood cover. The second is concentration. Between 10 and 12 percent of in-scope exposures sit in high-risk flood areas, and OSFI projects commercial exposures to stay more concentrated in those zones than residential ones.

Fire is the secondary hazard. OSFI projects the share of lenders’ exposures in high or very-high wildfire zones rising from 16 percent today to 29 percent by 2050.

The regulator also said what comes next. Future work will focus on whether institutions can measure and adequately price catastrophic and climate risk. OSFI’s climate guideline, B-15, is in force now, and it names the channel this brief is about. Physical risk means higher loan-to-value and loss given default because collateral values decline.

The losses are already moving collateral values. Insured severe-weather damage in Canada reached CA$8.55 billion in 2024, the first year above CA$8 billion. The remnants of Hurricane Debby flooded Quebec for about CA$2.7 billion of that, and flash floods in the Toronto area added about CA$990 million.

This is Signal 5, acute climate hazard, flowing into Signal 2, credit and mortgage markets, through Signal 1, insurance.

Deal Scenario

This is a modeled scenario, which means the numbers are not pulled from an actual deal.

A 60-unit older rental building in Vancouver, financed on CMHC-insured terms. Rent is CA$2,100 per unit per month, assumed at about 89 percent of CMHC’s October 2025 average for a purpose-built two-bedroom in Vancouver, which was CA$2,363. Vacancy is 3.7 percent, CMHC’s Vancouver figure. Operating costs are 38 percent of income, including insurance at 5 percent. That 5 percent is a U.S. benchmark from the Federal Reserve, used because no public Canadian series exists for apartment insurance; Canada’s multifamily commercial market runs on private data, broker reports, and specialized corporate tracking indices.

The loan is sized at CMHC’s minimum coverage of 1.20 on a ten-year term, with 40-year amortization and Canadian semi-annual compounding. The interest rate is 4.58 percent, an indicative ten-year CMHC-insured rate from Colliers, about 0.71 points over the Government of Canada ten-year bond. The cap rate is 4.25 percent, the middle of CBRE’s Vancouver range for older low-rise buildings.

On those inputs, net operating income is about CA$902,755, and the building supports a loan of about CA$13.9 million.

Now the renewal. Canadian commercial property insurance is getting cheaper right now. Marsh reports Canadian property rates down 8 percent in the second quarter of 2026, the ninth quarterly decline in a row, and Applied Systems puts real estate property renewals up just 1.02 percent in the first quarter. So a 50 percent jump is not the market. It is what happens to one building when its insurer identifies it as sitting in a high-risk flood zone at renewal. That is the stress being tested here.

• Insurance up 25 percent. The loan this building supports falls by about CA$280,000.

• Insurance up 50 percent. It falls by about CA$559,000. Net operating income drops 4 percent, and the loan drops 4 percent.

• Insurance up 100 percent. It falls by about CA$1.12 million.

Same building, same rent, same tenants. Then put the ladder next to the rate. If the ten-year rate rises half a point, to 5.08 percent, this building loses about CA$920,000 of loan capacity, more than the 50 percent insurance shock. Climate is one input. The rate is the one that gets you.

Underwriting Analysis

Five tests to run before your lender runs them. They are not all Canadian, and they are still valid data points for evaluating a deal or a portfolio at renewal.

First, know which test binds. The title of this brief names DSCR and LTV, and in this modeled scenario only one of them bites. The coverage ratio sets the loan. The loan sits at about 65 percent of value, well under CMHC’s 85 percent ceiling, before and after the shock. That 85 percent limit would only bind above a cap rate of about 5.53 percent, or if a lender cut the building’s value by more than about 23 percent for flood risk. Under insured terms in Vancouver, rising climate costs cut net income, which drops the deal below its permitted covenant ratio, and that is what costs loan proceeds.

Loan-to-value comes into play only with a large collateral haircut. How large can that get? A Bank for International Settlements working paper modeled a loan secured on commercial property in Mobile, Alabama. With a 3 percent annual chance of a major hurricane, the property lost 16 percent of its value, and loss given default rose from 10 percent to 24.8 percent. Even 16 percent stays under this building’s 23 percent threshold. That is an illustration from a working paper, not observed data, and it is a U.S. hurricane case.

Second, find out whose hazard map the lender uses, because the maps disagree. A study for the U.K.’s Climate Financial Risk Forum, written by Jo Paisley and Maxine Nelson at the GARP Risk Institute, compared 13 physical-risk vendors on the same 100 properties. For a one-in-200-year flood, the correlation between the damage estimates of eight of those vendors ran from 0.2 to 0.9. In one geocoding test, a vendor placed a property 1,507 kilometers from the median of the other vendors’ locations. Four vendors gave clients no measure of uncertainty. Which vendor your lender bought is a material fact about your loan.

Third, put insurance inside the coverage ratio, not in a footnote. The Federal Reserve estimates that in U.S. apartment buildings, a dollar increase in insurance costs cuts owners’ net income by about 72 cents. That is U.S. data, and Canada’s rent rules leave even less room to pass costs through. Your lender sizes the loan on the income that remains after that cost.

Fourth, expect the lender to act on the map, not just the price. Since February 2024, Desjardins, the largest mortgage provider in Quebec, has halted financing for property purchases inside the province’s highest-risk floodplains, even though that represents less than 5 percent of its mortgages, per La Presse. National Bank told La Presse it decides flood-zone loans case by case, including whether the property can be insured, how resilient the construction is, and the borrower’s financial strength.

The terms move, not only the price. From January 2026, European regulators expect banks to consider adjusting loan terms, tenor, and pricing based on a borrower’s ESG and climate criteria. Singapore introduced something similar in 2020, allowing banks to consider environmental covenants and to price the risk. In other words, a lender looking at a hazard-exposed property can charge more, shorten the term, or write conditions into the contract.

Fifth, hand the lender the file it does not have. Only 12 percent of lenders collect flood insurance data on their collateral. National Bank is already asking. Its 2025 sustainability report says it sends a climate questionnaire to corporate and commercial real estate borrowers, asking what percentage of their assets sit in regions vulnerable to extreme weather, and it discusses the answers at least once a year, at origination, review, and renewal. In its own table, residential mortgages, a quarter of its loan book, rate Moderate for physical risk. National Bank also says it is integrating an outside climate data solution, without yet saying whose.

So bring a hazard report, the flood coverage you have in force, and any mitigation you have done. Answer the question before it gets priced as an unknown.

Strategic Implications

Watch where the data is going, because it is arriving on the underwriting side first.

• The insurers moved first. In September 2025, Revau, a Canadian agency writing commercial lines, announced it is building the flood and wildfire models of Geosapiens, a Quebec City climate-risk modeling company led by co-founder and CEO Hachem Agili, into its underwriting platform. Revau promises more accurate underwriting from locally calibrated, building-level data.

• Then the carriers. In December 2025, Co-operators announced a long-term flood partnership with Geosapiens to sharpen risk assessment at the property and portfolio level, citing B-15. Co-operators says it has been an investor since the company’s first round.

• And the regulator. OSFI’s flood maps for the scenario exercise came from Riskthinking.AI in Toronto, founded by Ron Dembo. MSCI now owns First Street, the U.S. modeler.

• The caveat. Revau and Co-operators are insurers, not lenders, and neither release says whether the partnership covers commercial buildings or residential property. They show where pricing is heading, not where it has arrived.

What this means is that the same data now sits on both sides of the table. A borrower who buys the data before applying can dispute a bad score, show the mitigation, and argue for loan proceeds instead of accepting a blanket discount. A borrower who does not will be underwritten on somebody else’s map.

So underwrite yourself first. Before you refinance, run your coverage ratio at your insurance cost plus 25, 50, and 100 percent, and at a rate half a point higher. Get a hazard report and a flood insurance quote into the file. And ask your lender which vendor’s map it uses.

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

The regulator’s flood and wildfire findings — the OSFI and AMF standardized climate scenario exercise, covering over 250 institutions, CA$904 billion in mortgage and real estate assets and CA$3 trillion in insured property values, about 40 percent of Canada’s mortgages; 12 percent of deposit-taking institutions require or collect flood insurance information on collateral; 40 percent of homeowners buy optional flood insurance; 10 to 12 percent of in-scope exposures sit in high-risk flood areas, with commercial more concentrated than residential; wildfire exposure in high or very-high zones rising from 16 percent to 29 percent by 2050.

The rent is an assumption set at about 89 percent of CMHC’s October 2025 Vancouver two-bedroom average of CA$2,363, and the 5 percent insurance share is a U.S. Federal Reserve benchmark because no public Canadian apartment insurance series exists. The 50 percent shock is not the Canadian market; it is a single-building repricing case.

Lenders size a commercial mortgage on net operating income. When the insurance line rises and rent does not follow, the income the lender lends against shrinks, and the loan shrinks with it.

That is how climate data reaches a commercial mortgage today. Not through an announced climate premium on the rate sheet, but through the insurance line, the deductible rules, and the coverage ratio.

The storm shows up in the loan file before it shows up in the price.

Market Signal

A July 2026 working paper by Stefany Burbano and Nils Kok at Maastricht University and Rogier Holtermans at the University of Guelph puts a number on the insurance line. They reviewed 24 hurricanes that made landfall in the United States between 2010 and 2023 and cross-referenced the landfalls against the operating statements of large, institutionally owned commercial properties, measuring insurance as a share of total operating expenses. Across the sample, that share averaged 5.7 percent.

After a hurricane, exposed properties saw the share rise by about 1.2 percentage points nationally — roughly a fifth of the average. In hurricane-prone states, the estimate is about 1.7 points, closer to 30 percent of the average. Where properties took hurricane-force winds, the rise was 5.1 to 9.1 percentage points.

The paper also tested forward-looking hazard scores, and the result is the one underwriters should read twice. A wind score moved insurance costs. A flood score did not. Wind is what the insurance market is pricing, per the authors — although the paper has not been peer-reviewed, and the hazard scores it used were supplied by a commercial vendor.

In the same sample, insurance rose from about 3.0 percent to almost 6.8 percent of total operating expenses between 2017 and 2024, and from about $8,000 to nearly $24,000 per property per year. Scale turns out to be a hedge. Properties run by managers concentrated in one state saw post-storm increases of 2.3 to 2.9 percentage points. Properties with highly diversified managers saw 0.8 to 1.4.

Case Study

The best public numbers are national, so read what follows as national evidence applied to one market — Miami multifamily — rather than as a measured Miami result.

Start with the cost. Minjoo Kim, Prateek Mahajan and Zirui Wang at the University of Texas at Austin, writing for the Brookings Hutchins Center, studied more than 100,000 multifamily properties financed through Freddie Mac and Fannie Mae securitizations. Average growth in insurance costs exceeded 15 percent per year in every year since 2019, and reached nearly 30 percent in 2023. By 2024, insurance was about 9.9 percent of operating expenses, about 8 percent of net operating income and about 18 percent of debt service. Florida sits at the hard end of that range: a Federal Reserve note from September 2025 found per-unit insurance costs in 2024 were much higher in Florida and on the Louisiana and Texas coasts than in most of the country.

To be fair to the market, the latest Florida reading has eased. CRE Daily, reporting Trepp data, says the median insurance cost for securitized Florida apartment buildings fell 6.2 percent in 2025, after a 42.1 percent jump in 2023.

Then ask who pays. On average, the Texas team found about 49 percent of insurance-cost increases showed up in rents. But that response has faded to nothing. In 2014, a 10 percent rise in insurance costs went with a 0.35 percent rise in rent. By 2024, it went with 0.02 percent. The rest comes out of the owner’s income, and the Federal Reserve’s own estimate agrees: a dollar of extra insurance cost cuts apartment owner net income by about 72 cents.

That is counter-intuitive until you name the mechanism. Since 2024, a large supply of new rental apartments has come online, damping rent growth, and landlords face regulatory limits on how much and how often they can raise rents. They absorb the increase.

Buyers have noticed. After 2018, riskier properties sell at lower prices and higher cap rates — for each one-log-point step up in FEMA’s expected building losses, the same property trades about 6.5 percent lower per unit, with a cap rate about 11.8 basis points higher.

Now the lenders. In July 2025, Freddie Mac Multifamily raised the largest named-storm deductible it will accept from 5 percent to 7.5 percent of total insured value, and restated its wind and hail maximum of 5 percent on the same basis. Fannie Mae’s guide sets the same ceilings. HUD had already moved, in April 2024: for new FHA multifamily loans the maximum wind or named-storm deductible went from the greater of $50,000 or 1 percent, capped at $250,000, to the greater of $50,000 or 5 percent per location, capped at $475,000 per occurrence.

Put that on one asset, as an illustration and not a deal. Take a Miami apartment property insured for $40 million. Under Freddie Mac’s ceiling, the borrower can carry up to $3 million of loss per named storm before the insurer pays. Under HUD’s current cap, the same property would carry at most $475,000. That is more than six times the retained loss.

A bigger deductible can bring the premium down. It also moves the first loss onto the borrower’s equity — which is the lender’s cushion. HUD explains its own move differently, saying coverage at the old deductible could be hard to get or “may be unreasonably expensive”, and pointing to “the realities of climate change”.

Strategic Implications

Climate data now reaches the loan in five ways, and all five run through credit and mortgage markets.

• The coverage ratio does the pricing. Where insurance cannot be passed to tenants, it comes straight out of NOI, and the loan is sized on NOI. The Texas team estimates the cumulative 2014–2024 effect at about 5.1 percent lower NOI on average, and an implied 26 percent decline at the 95th percentile of insurance-cost growth — a modeled estimate for the hardest-hit tail, not an average. Their data also show higher insurance cost per unit going with a weaker debt coverage ratio. No bank has to announce a climate premium. The coverage test does the work.

• Banks told supervisors they lack the deductible data. In the Federal Reserve’s 2024 pilot climate scenario exercise, the six participating banks listed data gaps that included “levels and types of coverage, deductibles and replacement cost values”, and some “used external vendors to run simulations of thousands of potential hurricane events”. The storm model is available. What is missing is the borrower’s insurance schedule.

• Lenders move volume before they move price. Ralf Meisenzahl at the Chicago Fed studied the loan books of 35 bank holding companies and found a one standard deviation increase in flood risk reduced commercial real estate lending in the riskier area by about $5 million, or about 12 percent of the sample mean, between 2014 and 2019. That is flood rather than wind, and it measures how much banks hold rather than what they charge.

• Coverage failures are already in the distress numbers. Multifamily Dive reported in August that CRED iQ’s founder and chief executive, Michael Haas, pinpointed year-on-year increases of as much as 100 percent in insurance and property tax, which pushed the debt coverage ratio below 1.0X on 39 of the 98 multifamily loans CRED iQ evaluated. That is trade reporting, it combines insurance with tax, and it does not say which loans — but it is the loan-level version of everything above.

• Index providers are buying the data. In June 2026, MSCI agreed to buy First Street, the physical climate risk modeler, for a $120 million cash payment at closing, plus possible payments over two years tied to revenue targets. MSCI completed the deal on August 3, and First Street’s data now covers more than 2.4 billion structures.

There is a gap worth naming. We looked for a public study of commercial loan spreads against hurricane exposure and did not find one. What exists points the same way — Holtermans, Kahn and Kok have tied hurricanes to higher commercial mortgage delinquency, and other work ties flood and sea-level exposure to CMBS deal spreads — but nobody has yet published the loan-level rate. The pricing channel is visible in the coverage test and in lending volume, not yet in a measured spread.

Future Signal

Matthew Eby, founder and chief executive of First Street, framed the acquisition this way when MSCI announced it: joining MSCI “puts our property-level science in front of the world’s leading investors, lenders, and insurers, and turns climate risk from a disclosure exercise into a daily input for how capital is priced and allocated.” It is a founder’s statement at sale, and should be read as one. But the direction is not in dispute.

Rich Sorkin, co-founder and chief executive of Jupiter Intelligence, has put his company’s analytics inside JLL’s risk advisory platform so that professionals can, in his words, “quantify physical climate risks with the same rigor they apply to market and credit risk”. And the detail that closes the circle: the Burbano, Holtermans and Kok paper that opens this brief used Jupiter’s hazard scores. That is where the wind-versus-flood result comes from.

At the other end of the chain, CRED iQ tracks more than $2.3 trillion in commercial loans by aggregating property, financial, loan, tenant, and ownership data — which means it can already see the loans where the coverage ratio is breaking.

One more signal sits on the agency side, and it is still only a proposal. HUD has a draft out for public comment that would drop the $475,000 cap it now calls “too restrictive”, keep the 5 percent limit, measure it per building, and require owners to show cash of two to three times the deductible. As of this writing, it has not been finalized as a rule, and you should not plan around it.

The next change is unlikely to be a rate premium announced by a bank. It is a hazard score and an insurance schedule sitting beside the rent roll in every commercial loan file, with the deductible sized to the storm model rather than to a flat percentage.

So underwrite the deductible, not only the premium. Before you refinance a coastal asset, price the retained storm loss the new rules allow. Model NOI with insurance growing and rent not following. And bring the hazard data to your lender before your lender brings it to you.

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

Hurricanes and the insurance line — across 24 U.S. hurricane landfalls from 2010 to 2023, insurance as a share of total operating expenses rose about 1.2 percentage points at exposed properties nationally and about 1.7 points in hurricane-prone states, against a sample mean of 5.7 percent; under hurricane-force winds the rise was 5.1 to 9.1 points; a forward-looking wind hazard score moved costs while a flood score did not; and the ratio rose from about 3.0 percent to almost 6.8 percent, and from about $8,000 to nearly $24,000 per property per year, between 2017 and 2024.

Florida per-unit costs and owner income — per-unit apartment insurance costs in 2024 were much higher in Florida and on the Louisiana and Texas coasts than in most of the country, and a dollar of extra insurance cost reduces apartment owner net income by about 72 cents.

The agency deductible ceilings — Freddie Mac Multifamily raised its maximum named-storm deductible from 5 percent to 7.5 percent of total insured value and restated its 5 percent wind and hail maximum on the same basis, effective for new loans from July 24, 2025; Fannie Mae’s Multifamily Guide sets the same 7.5 percent and 5 percent ceilings.

The HUD FHA deductible cap and its stated reason — for new FHA multifamily transactions from April 17, 2024, the maximum wind or named-storm deductible is the greater of $50,000 or 5 percent of insurable value per location, up to $475,000 per occurrence, replacing the greater of $50,000 or 1 percent capped at $250,000; HUD said coverage at the old level “can be difficult to obtain ... or ... may be unreasonably expensive” and cited “the realities of climate change”. A draft HUD mortgagee letter out for comment would drop the $475,000 cap as “too restrictive”, keep 5 percent measured per building, and require owner liquidity of two to three times the deductible.

Welcome to Climate-Ready Real Estate Investing.

Real estate is the world’s largest store of wealth. Savills puts the value of all global real estate at USD $393 trillion at the start of 2025, more than all global equities and debt securities combined. That asset class is undergoing a structural shift that is reshaping values, development strategy, and capital flows.

This publication is about that shift, not as ideology, but as market structure.

What Climate-Ready Real Estate Investing is

CRREI treats climate change as a financial transmission mechanism. It reaches a property through insurance, operating costs, migration, financing, and regulation, usually well before it reaches the headlines. The question here is never whether you believe in it. The question is whether it is already in your numbers, and whether you know it.

The framework under every brief is the Climate-Ready Deal Framework™, the CRDF. It tracks twelve anchor signals across four groups: capital and credit, physical risk, regulatory and policy, and structural economic forces. Every brief names the signals it is reading.

Three intelligence briefs each week translate those signals into analysis you can use:

• Market Intelligence, Mondays: what is moving in insurance, credit, capital and markets, and why.

• Strategy & Underwriting, Wednesdays: how to put that signal into a pro forma, a loan or a hold decision.

• Story & Future Thinking, Fridays: the places and precedents that show where the market is heading.

Two companion tools take the signals down to the deal. The CRDF Signal Tracker™ records what you are seeing in your own market against the twelve signals. The CRDF Deal Stress Test™ runs a specific asset through a climate-adjusted underwriting, from insurance and operating costs through to exit value. Every Market Intelligence brief comes with a worked Signal Tracker example, and every Strategy & Underwriting brief with a worked Deal Stress Test, so you can see the method before you apply it to your own deal.

Who it is for

Real estate investors, developers and investment firms. Private equity real estate. Lenders, insurers and fintech professionals. Supply chain companies and climate tech founders. And the municipal planners, architects and community developers whose decisions set the conditions everyone else underwrites.

The frame is global. Valencia, Rotterdam, Sydney, Tokyo, Medellín and Mexico City show up here as often as Florida and Phoenix, because the signal usually appears somewhere else first.

Why I write it

I’m Jamie Wolf, a WSJ bestselling author. I have been active in real estate, founded businesses, appeared on the NASDAQ billboard, and I hold an MBA. What’s most relevant today is that I’m a writer, an observer, and a synthesizer who frames climate risk in terms of market structure through the Climate-Ready Deal Framework^TM.

I am not your lawyer, broker, lender, or underwriter. I provide commentary, not advice, so that you can know your signals and be Climate-Ready. Translation - ALWAYS do your own due diligence.

I don’t intend to debate the cause or existence of climate change. Recycling, green manufacturing, species protection, clean soil, air, water, and oceans, and the growing number of climate refugees all matter. But the most direct route to changing behavior is the cost-benefit argument.

Personally, I would choose not to cut down a tree or a forest simply for the sake of that tree . . . its beauty, its longevity, and all the fungi, insects, plants, birds, and mammals that depend on it. That argument won’t change the math or sway a politician, a corporation, a hedge fund, or a developer. It won’t stop the burning or the bulldozers.

So this is a conversation in the language real estate already speaks - risk, return, cost of capital, and exit value. The aim is for you to be profitable today while ensuring there is a tomorrow, and to help you realize that supporting resilient communities and resilient returns does not have to be an either/or choice. The desire supporting all of this conversation comes from the Hippocratic Oath - please - first, do no harm. What we develop, and how, shapes the future viability of both real estate and our one planet.

Peer-reviewed measurement puts subsidence in the worst parts of Mexico City at 50 centimeters per year, close to twenty inches, and finds the rate “mostly constant since at least 1950” and “almost fully irreversible.”

Properties in those districts keep changing hands at prices set by comparable sales that assume the land is stable.

That is not a failure of diligence. It is what an appraisal is built to do, and it is the single most under-examined gap in real estate valuation.

The Moment

From orbit, NASA’s NISAR radar can watch the city drop.

Between October 25, 2025 and January 17, 2026, the mission measured parts of the metropolitan area “subsiding by more than half an inch, more than 2 centimeters, per month,” with Benito Juarez International Airport sitting near the center of the mapped area. By the 1990s and 2000s, NASA notes, parts of the city were sinking at around fourteen inches per year.

This is not a slow-motion abstraction, and it is not a forecast. It is a measured rate under a functioning international airport in one of the largest cities on the planet, taken this year.

The physical mechanism is well established. The city sits on the bed of an ancient lake. Decades of extraction have drawn the aquifer down faster than it recharges, and the clay beneath compacts as the water leaves, so the ground subsides unevenly, building by building.

The peer-reviewed work that established the rate did so by integrating 115 years of leveling with 24 years of satellite radar and 14 years of GPS. Its conclusions are noteworthy. The rates have been broadly constant for seventy years. The compaction is almost fully irreversible, so recovering the aquifer would not raise the ground. And the authors forecast roughly 150 years of continued compaction, with up to 30 meters of additional subsidence still to come.

A hazard that is measured, constant, irreversible, and forecast a century and a half forward is about as legible as physical risk ever gets. And it is still not in the comps.

The Story

To understand why, look at what an appraisal actually is.

A comparable-sales appraisal records what other people recently paid. By construction, it is a backward-looking instrument. That is not a flaw. It is the entire methodology, and it works extremely well for any risk that is already reflected in transaction prices.

It fails on exactly one class of risk, that of a hazard that is knowable in advance, changes slowly, and has not yet produced a transaction that prices it. Chronic subsidence is the purest example available.

Compare it with a flood zone. A FEMA designation is a published, parcel-level, forward-looking statement about hazard, and because it is published, and because lenders require it, it reaches the price. The information does the work only because a rule forces it into the room.

Subsidence has the measurement, not the rule. There is no designation, no mandatory disclosure at the point of sale, and no lending requirement to obtain a reading. So the data exists and never meets the transaction.

Insurance quietly widens the same gap. Earth movement, which standard property forms cover as earth sinking, rising, and shifting, is excluded from most US property policies, including all-risk forms. The federal flood policy excludes “land subsidence” by name. The cost of foundation and utility damage therefore migrates from the carrier back to the owner, which means it never appears in a claims history either, and a claims history is one of the few forward-looking inputs an underwriter actually reads.

And there is a second-order effect, one that’s almost too obvious to be mentioned. Ground that has subsided sits lower than it did, and lower ground collects water. A district can face damage from too little water in the aquifer and too much water at the surface, from the same cause.

How large is the price effect? Nobody has published a defensible answer for Mexico City. The physical measurement is excellent, and the valuation research is thin to absent, which is itself a finding. When someone does measure it, the number will land in a market that has been transacting without it for decades.

The policy machinery has started moving on the cause, though not on the pricing. Mexico published a new General Water Law in the Diario Oficial de la Federación on December 11, 2025, which took effect the following day, reorienting the system toward basin-level governance. It both creates the new law and reforms the 1992 National Waters Law, which remains in force. Several provisions widely attributed to the new law, including the national water registry, sit in the reformed older statute instead. It addresses extraction. It does nothing to help a buyer price the effect.

Structural Forces

Three forces hold the gap open, and a fourth is starting to close it.

One: comps are backward-looking by design. When the hazard is chronic rather than a dated event, the comparable set encodes a world that no longer exists, and value lags physical reality until a transaction finally reprices it. No mechanism inside the appraisal can anticipate it.

Two: chronic hazards have no trigger date. Unlike a flood or a fire, there is no single day the loss occurred, so there is no claim, no headline, and no moment that forces a number down. Damage accrues to foundations and systems continuously, beneath the appraisal’s line of sight and beneath the policy’s.

Three: the supply side has no answer to sell. This month’s briefs have followed builders and suppliers certifying a shingle, engineering a frame, or shaping a tower against the wind. Every one of those answers works because the hazard produces a testable performance standard a manufacturer can certify to. Subsidence does not. No rating exists for a foundation that outlasts a sinking aquifer, and no carrier offers a discount for one.

That asymmetry is itself an investment signal. Where a hazard has a certifiable product, the cost of managing it is shared with a manufacturer and priced through a warranty. Where it does not, the burden falls on the owner and the lender.

Fourth, and this is the one that changes: the measurement has arrived. The United States now has a peer-reviewed baseline. Researchers using space geodetic data from 2015 to 2021 found that in all 28 of the most populous US cities, at least 20% of the urban area is sinking, affecting roughly 34 million people, with more than 29,000 buildings in high- or very high-damage-risk zones. Houston is the fastest, with 42% of its land area subsiding faster than five millimeters per year.

That is the same hazard, in the same asset classes, under the same appraisal methodology.

The Next Chapter

The gap will close. The only question is how violently, and the sequence is predictable because every priced hazard has run it.

First a hazard becomes measurable.

Then it becomes disclosed.

Then it becomes priced.

Flooding took decades to move through that sequence and needed a federal program to force the middle step. Wildfire is somewhere in the middle of it now, pushed along by carriers rather than regulators. Subsidence has just completed step one.

So watch the disclosure requirement, not the satellite. The technology to measure this at parcel level on a schedule already exists, and NISAR’s public data release began in July 2026. What is missing is the rule that puts the reading in front of a buyer before closing, or in front of a credit committee before funding.

When that rule arrives, it will not arrive gently, because there is no partial version. The day a lender begins requiring a subsidence reading is the day every asset in a fast-subsiding district reprices at once, and the repricing will reflect a hazard that has been accumulating, measurably, for seventy years.

The transferable pattern runs from Mexico City to Houston’s western suburbs, to Jakarta and Dhaka, to the US coasts. Any market where the ground or water is moving faster than the comp set is carrying value that hasn’t been marked.

So the question for investors, lenders, and appraisers is this. If the ground itself is moving and your comparable set cannot see it, are you buying an asset or a liability the market has not yet dated?

The number on the appraisal reflects the past. The risk is a fact about the future. The investor who prices the second before the market reprices the first is the one not holding the gap when it closes.

And the discipline generalizes past subsidence, which is why it closes four weeks spent on what buildings can be made to survive. Measure the thing before you are forced to price it, whether that thing is a shingle’s impact rating or a foundation’s sinking rate. Building science asks what survives.

The harder question, and the one this publication turns to next, is who decides what that survival is worth and how quickly the money works it out.

Colorado has just legislated a 0.5% fee on multiperil homeowners premiums, with at least 85% of the revenue going to hail and wind retrofit grants, and a new requirement that insurers report what they actually credit for a resilient roof.

That reporting requirement is the tell. The state is legislating to find out what the discount is, which means nobody currently knows.

If you are modeling a Class 4 roof upgrade against a premium discount, you are modeling a number that is not published anywhere in the country.

Market Signal

Two Colorado statutes changed the ground under this decision within fourteen months, and both are routinely cited incorrectly.

The first is House Bill 25-1182, signed May 28, 2025, creating a new section of the insurance code. It requires that where an insurer does not build property-specific and community-level mitigation into its models, the insurer “shall provide discounts to policyholders who can demonstrate that property-specific mitigation actions have been undertaken on the property.” It took effect July 1, 2026.

The requirement is conditional, biting only where the carrier has not already modeled mitigation. It triggers on a wildfire risk model, catastrophe model, or scoring method. And it prescribes no discount size at all.

The second is Senate Bill 26-155, signed June 4, 2026, and effective August 12, 2026. Its title is “Increase Access Homeowner’s Insurance Enterprise,” and it creates the Strengthen Colorado Homes Enterprise, a government-owned business within the Division of Insurance.

From calendar year 2027, the enterprise levies a fee equal to 0.5% of the total multiperil homeowners premium an insurer collected in the immediately preceding calendar year. At least 85% of that revenue must fund grants to Colorado homeowners retrofitting residential property against hail and windstorm loss.

Three qualifiers matter and are almost always dropped.

• The fee is capped at $100 million per year for the first five years.

• It may not be passed through to policyholders.

• And the reporting duty begins “no sooner than January 1, 2027, and upon the commissioner adopting rules,” so it depends on rulemaking rather than being automatic.

The reporting is designed to collect the following: policies in force, the number of homes with a resilient roof system, the discount applied for one, wind and hail claim frequency, and the severity for homes with and without.

Colorado is about to publish the first systematic dataset on what a resilient roof is actually worth. Until it does, anyone quoting a percentage is quoting a carrier’s marketing or someone’s guess.

The geography justifies the effort. The Front Range sits inside Hail Alley, and the regional insurance association describes residents as able to “count on three or four catastrophic hailstorms every year,” defining catastrophic as at least $25 million in insured damage. The May 8, 2017 Denver metro storm remains the reference event at $2.3 billion, stated in nominal 2017 dollars.

Deal Scenario

Model a 96-unit garden-style multifamily asset in the Denver metro Hail Alley corridor, organized across eight buildings on a $19.2 million basis, with each building carrying a roof at the end of its useful life. This modeled scenario tests one decision.

At the reroof, the choice is a standard architectural shingle or a UL 2218 Class 4 impact-resistant shingle.

Note the standard’s definition, because the two most common shorthand phrases are wrong. UL 2218 is a steel-ball drop test that assigns a pass-or-fail class. The Insurance Institute for Business and Home Safety runs a different program entirely (here in my adoptive home state of South Carolina). It propels laboratory-manufactured hailstones at roofing products and reports graded, relative performance across dents, tears, and granule loss, “structured to distinguish relative performance” rather than to pass or fail.

IBHS built that protocol precisely because the UL class does not discriminate real-world hail performance. A Class 4 designation therefore does not confer, predict, or guarantee any particular IBHS rating. If you want both, you specify both, and you check the product on both lists.

No defensible public price series exists for a Class 4 upgrade. The figures that circulate trace to contractor lead-generation sites, and the Class 4 half of the comparison, which is the entire point, has no source at all. So take the delta from your own bids, and for the illustration assume $40,000 across the eight buildings, about 0.2% of basis. Replace it with your number. The argument below intentionally does not depend on the price.

Underwriting Analysis

There are four parts, in the order they decide which shingle type to use when you reroof.

First, the discount cannot carry the case, because the discount is not knowable. Colorado’s own legislature has just required insurers to begin reporting resilient-roof discounts, meaning the regulator does not currently collect them. HB25-1182 mandates that a discount exist in certain circumstances but sets no size. No filed schedule for multifamily hail mitigation exists anywhere in the United States.

So write the discount into the model as an unknown with a range you can defend to yourself, and then test whether the deal works at zero. If it only works at 30%, the deal is a bet on a number the state is currently trying to discover.

Second, the real return is claims frequency, and that is what the hail cannon exists to measure. IBHS built an impact protocol because roof performance under impact directly predicts claims frequency and severity. A roof that generates fewer claims produces a better loss ratio, and carriers renew better loss ratios.

On the benefit-cost side, use the right cell. The National Institute of Building Sciences puts private building retrofit at $4 per $1 nationally across all hazards, and above-code design at the same $4 per $1. The widely repeated $13 per $1 is the seismic retrofit figure, and no hail-specific published ratio exists. Treat $4 as an order-of-magnitude sense check on avoided loss, not as a hail return.

Third, the grants are coming, and they are bounded. From 2027, the Colorado enterprise directs at least 85% of a 0.5% premium fee to retrofit grants, capped at $100 million annually. That is real money arriving on a known date into a known peril, and it is the first item in this analysis with a statutory number attached. It is also a homeowner grant program, so check eligibility against your asset class before it enters a pro forma.

Fourth, and decisively, the ceiling is insurability, not price. As in the wildfire and hurricane-wind markets covered in earlier briefs, the case that ends the argument is not a bigger discount. It is non-renewal. A documented Class 4 roof, verified against a published performance rating and evidenced with a permit, a certificate, and a manufacturer’s record, is what keeps a Hail Alley asset insurable at all in the hardest-hit ZIP codes.

Run the sequence in that order, and the decision usually resolves before you reach the discount line, which is the point.

Strategic Implications

• Build the paper trail, not the argument. From 2027, a Colorado insurer will file the discount it applied for a resilient roof. The owner who can produce the permit, the certification, and the installation record is the one whose credit appears in that filing. Documentation is the asset.

• Specify to the peril your market actually has. Hail in Colorado is not wind in Alabama and is not fire in California. Each has its own standard, testing body, and state architecture, and none of the three benefit-cost ratios is interchangeable.

• Watch the fee’s incidence, not just its size. SB26-155 bars the 0.5% from passing through to policyholders, making it a charge against carrier margin in a state where several carriers have already narrowed appetite. The second-order effect on availability is worth watching more closely than the grant program itself.

• Assume the first published dataset changes the market. When Colorado publishes claim frequency and severity for homes with and without a resilient roof system, that becomes the first public evidence base for hail mitigation economics in the country. Whichever way it comes out, every model built on an assumed discount gets repriced against it.

• Don’t let a manufacturer’s class stand in for a performance rating. Ask for the UL 2218 class and the IBHS impact rating separately, in writing, with the product name and version on each.

A wider shift underlies all of this. A design choice that used to be a voluntary underwriting credit is becoming state-tracked through reported rate factors, state-funded through a dedicated enterprise and, from 2027, state-audited through mandatory insurer reporting.

For an owner, that changes who the spec sheet conversation is with. It used to be one underwriter. Increasingly, it is the underwriter, the state regulator, and a future buyer’s diligence team, all reading the same public record.

As always, KNOW YOUR SIGNALS and BE CLIMATE READY!

In the first half of 2026, storm activity ran about 20% above average and global insured catastrophe losses came in at $42 billion, the lowest first half since 2020.

West of Houston, a regional water authority has raised the fee it charges per thousand gallons from $0.50 in 2004 to $3.95 today because the ground beneath its service area is sinking and the regulator has ordered it to stop pumping.

The first number is what an acute year looks like when the storms miss the insured footprint. The second is what a chronic hazard looks like when it finally reaches an operating statement. Neither produced a claim, and only one is in your model.

Market Signal

Physical climate risk arrives on two clocks.

Acute risk is an event. A storm, a fire, a flood, on a single date, producing a single claim and a single repair bill. It is volatile, it is insured, and because it is insured, it is measured, reported, and priced within a year of happening.

Chronic risk is drift. Sinking ground, rising heat, retreating water. It accrues continuously as a slightly higher operating cost, a slightly earlier capital replacement, a slightly lower valuation, and it never produces the moment that forces a number down. It is rarely insured, so it is rarely measured, and what is not measured is not in the comps.

Start with the acute side, because 2025 and 2026 together show how little a loss total tells you about hazard.

Swiss Re Institute puts 2025 global insured natural catastrophe losses at about $107 billion against economic losses of about $220 billion, with the Los Angeles wildfires at roughly $40 billion and severe convective storms at $51 billion. Secondary perils accounted for 92% of insured losses. Aon’s separate tally runs higher, at $127 billion insured, with severe convective storms at $61 billion, the third-highest annual total on record for that peril.

Then the first half of 2026 arrived below trend. Swiss Re counts $42 billion of insured losses against a long-term trend estimate of $66 billion, with severe convective storm at $28 billion, the lowest since 2021. Aon puts first-half economic losses at $111 billion, 25% below the twenty-first-century average, with the United States accounting for 75% of global insured losses in a half-year whose largest single event was an earthquake sequence in Venezuela.

It carries different weight when you look at the two-year combination. Swiss Re’s own explanation for the quiet half is that storm activity ran about 20% above average and yet relatively few of the highest-impact events affected densely populated and highly insured areas. High frequency, low insured loss. That is not a calm year. It is a year whose losses landed where the insurance was not.

Which is the point about acute risk that most underwriting misses.

The loss total says where the storms went and who was insured. The hazard did not move. Swiss Re attributes more than 80% of the long-term rise in weather-related insured losses since 1970 to exposure growth, meaning more development with higher asset values in harm’s way, rather than to the climate signal itself.

So carriers price acute risk annually, based on a loss history that is itself noisy. Nobody prices chronic risk, and it arrives through a different door.

Case Study

Houston’s western suburbs show what that door looks like.

The Harris-Galveston Subsidence District runs a network of more than 190 GPS stations across the metro. Station P029, in Katy, has recorded about 35 centimeters, or about 14 inches, of subsidence since 2007, and from 2021 to 2025 it was still sinking at 2.64 centimeters a year. The fastest station in the network is P111, near Fulshear in Fort Bend County, at 3.31 centimeters a year. Both are on the western side of the metro, where growth has been fastest. The District’s Regulatory Area One, closer to the coast and converted off groundwater decades ago, shows rates below half a centimeter a year, so quoting the fastest stations as a regional rate overstates it several times over.

The peer-reviewed picture agrees on where the problem sits. Space geodetic measurements from 2015 to 2021 find Dallas, Fort Worth, and Houston have the highest proportion of sinking area among the largest US cities, with over 70% of their land subsiding faster than three millimeters a year.

Houston is the fastest of the group, with 42% of its land area subsiding faster than five millimeters a year and 12% faster than ten. San Antonio, Austin, and Houston together hold more than 82% of the buildings that the study rates at very high risk.

The cause is groundwater withdrawal, and that detail turns a geology story into an operating-cost story, because the regulator’s response to the cause is what reaches the property.

The District regulates by area. Regulatory Area One may draw no more than 10% of its annual water demand from groundwater, and Area Two no more than 20%. Area Three, which is the western growth corridor, has been on a conversion schedule that states no more than 70% groundwater through 2025, 40% from 2025, and 20% from 2035 for permittees on a certified reduction plan.

That schedule is why the West Harris County Regional Water Authority exists. It has no taxing authority. It buys and pipes surface water, estimates its conversion program at more than $1.5 billion, and recovers the cost through a fee on every thousand gallons its member districts pump or receive. In 2004, that fee was $0.50 per thousand gallons of groundwater. It rose in almost every year since, to $1.25 in 2010, $2.05 in 2015, $3.20 in 2020, and $3.95 in 2023, where it has stayed through 2026. Surface water is $4.35. The 30% conversion milestone was met in 2010 and the 60% milestone in 2025. The 80% milestone falls in 2035, and the fee schedule is the funding instrument.

Put that on a building. The following is a modeled illustration, not a transaction. A 300-unit garden apartment community in Katy using 100 gallons per unit per day draws about 11 million gallons a year. At the 2004 fee, the authority charged about $5,500 a year for that volume. At the 2023 fee it is about $43,000 on groundwater, or about $48,000 if the district has converted to surface water. That is roughly $40,000 a year of operating cost that did not exist when the asset was underwritten in 2004, before the property’s own utility rate. At a 6% capitalization rate, it is about $630,000 of value.

No storm produced it. No claim was filed. No catastrophe report lists it. A regulator ordered a region to stop sinking, and the cost of that order arrived on a water bill, in increments of twenty-five cents, for nineteen years.

That is chronic risk, and it is dangerous not because of its size. It is that every increment was small enough to absorb, and no one ever re-derived the line.

Strategic Implications

• Model the two tempos in two columns that never merge. Underwrite acute risk for volatility, using the hazard multiplier, the deductible, the carrier count, and the claims history. Underwrite chronic risk for compounding drift, in the utility, insurance, and capital reserve lines, even when nothing hands you the number.

• A compounding hazard modeled as a flat input is the most common error in a long hold. A pro forma carries a wind or fire multiplier because the last catastrophe-model update priced one. It rarely carries a drift for subsidence, cooling load, or water because those arrive as a trend that has to be modeled actively rather than inherited from last year’s template. It is the single most common reason a five-year hold underwrites cleanly and a ten-year hold does not.

• Follow the regulator, not the geology. Subsidence, water stress, and heat reach an operating statement through a rule: a groundwater conversion schedule, an allocation cut, a cooling standard. Physical data usually precedes the rule by years, and the rule reprices the asset. The Harris-Galveston conversion milestones have been public since the 1990s. The 2035 step is already on the calendar.

• Read the loss total as a map of who was insured, not as a measure of hazard. A below-trend year with above-average storm activity is not evidence that exposure fell. It shows the events missed the insured footprint that year. The next year’s renewal will not be priced off that half.

• Date every dataset in the same paragraph. The geodetic study measures 2015 to 2021, the District’s station rates cover 2021 to 2025, the loss figures are full-year 2025 and first-half 2026, and the fee schedule runs 2004 to 2026. Mixing vintages is how a fast station becomes a regional rate and a quiet half becomes a trend.

Future Signal

Watch the modeling industry split its own product line, because that is where the two clocks are being separated for sale.

Cotality, formerly CoreLogic, now sells a chronic-perils product distinct from its catastrophe models. It notes 84 indices with property-level scores on a 1-to-100 scale across four chronic perils: cold wave, heat wave, extreme precipitation, and drought. Acute hazard - meaning flood, hurricane, earthquake, and severe convective storm - sits on a separate line. A client who has bought one has not bought the other, which is a vendor’s way of saying the two tempos are different risks with different data, and the industry has stopped pretending one model covers both.

The same separation is appearing on the insurer side. Moody’s catastrophe-modeling group published its own paper on heat and water stress in August 2026, sampling roughly 159,000 water-intensive US facilities and finding nearly 49,000 facing high or very high water stress in the coming decades, with Texas and California the most concentrated. Its head of catastrophe modeling described heat and water as perils that “are converging, and doing so quickly.”

What follows from that is a sequence, and it runs the same way for every hazard. A vendor scores a chronic peril. The score reaches a lender’s screen. The screen reaches a term sheet. Flood risk took decades and a federal program to run it. Chronic perils now have the vendor scores. They do not yet have the screen.

There are three things to watch.

Whether a lender writes a chronic-peril score into a credit policy, because the first one to do so sets the template.

Whether the Harris-Galveston 2035 milestone produces a fee step in the western authorities’ schedules, because that is the next chronic-cost increment already on a public calendar.

And whether the second half of 2026 returns acute losses to trend, because if it does, the first half will be remembered as what it was, a lucky map rather than a quiet climate.

Brief 5 ran the acute side through a levered Sun Belt deal and found the covenant broke before the return did. Brief 36 takes the chronic side to its conclusion and asks what an appraisal does with a hazard the comps cannot see.

In 2023, the United States appropriated $2.15 billion to buy low-embodied-carbon concrete, steel, asphalt, and glass, assigning $2.0 billion to 154 federal projects, with global warming potential limits and environmental product declarations required at the bid stage.

By January 31, 2025, $767 million had been obligated. Disbursements were frozen on February 13, 2025. That July, Congress repealed the authorizing section and rescinded the unobligated balance, which the allocation and obligation figures put at roughly $1.38 billion.

The building-science revolution is real, the performance evidence is strong, and the policy that was going to lock it in just went backward in the world’s largest procurement market. Both are true, and an investor has to hold them at once.

The Moment

Start with a photograph from Mexico Beach, Florida, in October 2018.

Hurricane Michael made landfall near Tyndall Air Force Base on October 10, 2018, at 140 knots (about 160 miles per hour), with a central pressure of 919 millibars. The National Hurricane Center recorded a storm surge of 14.7 feet above mean higher high water at Mexico Beach. In post-storm analysis published in April 2019, Michael was upgraded to Category 5, the first hurricane to make landfall in the United States at that intensity since Andrew in 1992.

An aerial shot shows a mile of coastline scraped to the slab. One house stands almost alone.

It is reinforced concrete on 40-foot piles driven 28 feet into the ground, with the first floor lifted about 15 feet to let the surge pass underneath. Independent reconnaissance engineers who surveyed it recorded a home “built above code minimums for Bay County, at a cost of roughly double per square foot,” which “lost only its stairs and breakaway walls, with some minor water damage.”

That last clause is the part usually left out. The breakaway walls broke away. That is what they are for, much like modern cars, which are designed with outer crumple zones that collapse in a controlled way to absorb crash energy and lower the peak force that reaches the occupants. The building was designed so that the parts below the design flood elevation would surrender and the structure above would not, and both halves did exactly that.

Fifteen feet of finished floor against fourteen point seven feet of surge is not luck. It is a decision made on paper, years earlier, by somebody who read the flood map and then added margin.

Of note, the 250-mile-per-hour rating belongs to the insulated concrete form product used in the walls. It is a manufacturer’s wall rating, not a whole-building design wind speed. Engineers don’t design a house to a wind speed rating. The two verified numbers are the doubled cost and the survived surge, and they are enough.

The Story

Widen the lens, because the same principle applies to every hazard, and the best evidence is not American.

In Maasbommel, on the banks of the Meuse in the Netherlands, 32 amphibious houses sit on a concrete base with a timber frame above, moored on steel guideposts. When the river rises, they float up to 5.5 meters and settle back as it falls, like every dock on coastal water subject to daily tide changes. The European Environment Agency recorded the first real test. In 2011, the Meuse rose far enough for the amphibious houses to float for the first time, and “in floating condition there were no problems detected.”

In Shanghai, one of the world’s tallest towers carries a façade that curves through 120 degrees from base to crown. The structural engineer of record said refining the form in a wind tunnel “reduced building wind loads by 24 percent, which resulted in a lighter structure and reduced material cost.” Not by resisting the wind. By letting it slide past.

And in May 2023, engineers put a full-scale ten-story mass timber building on a shake table at the University of California San Diego. They hit it with records from the 1994 Northridge and 1999 Chi-Chi earthquakes, the second a magnitude 7.7. The building “remained damage-free after two major design-level earthquakes back to back.” Peak interstory drift reached 2.33%, and the post-tensioned rocking walls returned the structure to plumb with negligible residual displacement.

That last result matters most, and it is routinely undersold as “it stayed standing.” A steel or concrete building of that height would be expected to survive. But wood? The timber building survived and re-centered, with damage confined to replaceable steel fuses—a low-carbon material performing like a high-performance one.

Which brings the tension into focus. The Mexico Beach house bought its survival with carbon-heavy concrete. It proved that resilience is a design choice, and it proved it using one of the most emissions-intensive materials available.

The quiet revolution is delivering that same multi-hazard survival at far lower carbon, and the reason structural materials are the battleground is calculable.

The Institution of Structural Engineers’ benchmarking data puts the superstructure at 40% to 47% of a building’s capital carbon and the substructure at a further 11% to 17%. Together, this typically accounts for over half and up to about two-thirds in heavy-frame buildings, though the share falls sharply for low-rise timber housing and fit-out-heavy refurbishments.

The market is moving. The Business Research Company, a private market-sizing firm, puts the global market for low-carbon construction materials at about $281.8 billion in 2025, rising toward $306.5 billion in 2026. The caution with these figures is that, as yet, “low-carbon construction material” has no agreed boundary.

Structural Forces

Three forces decide who wins, and the first one just reversed direction.

Force one: regulation pulls the material, and it does not pull steadily.

The United States is the example at the top of this brief, and what replaced the $2.15 billion program is nothing. Projects that had money obligated before the February 2025 freeze still have to meet the low-carbon material requirements. No new projects are being funded, and no successor program exists. The same July 2025 act also repealed the Environmental Protection Agency’s $250 million fund that helped manufacturers produce the environmental product declarations those requirements depend on.

In Europe, the Ecodesign for Sustainable Products Regulation, adopted in June 2024, is the horizontal framework for digital product passports, but it does not currently cover construction products. Its own text bars cement requirements before December 31, 2028, and the first working plan prioritizes textiles, furniture, tires, mattresses, iron and steel, and aluminum. The construction passport arrives instead through the recast Construction Products Regulation, in force since January 2025 and applicable from January 2026, delivered through delegated acts phased across 2026 to 2029.

Canada is often described as tying infrastructure funding to embodied-carbon audits. Its Treasury Board standard requires federal construction contracts of $10 million or more to disclose and cut the embodied carbon of ready-mix concrete by at least 10% against a baseline mix. One material, its own procurement, is in force since the end of 2022.

So the accurate picture is three jurisdictions moving at three speeds in two directions, and an assumption that synchronized regulatory pull will be wrong somewhere.

Force two: durability changes the lifecycle math. A material that survives the event and lasts longer produces lower insurance cost, lower replacement cost, and higher residual value. That is the adaptation-capex-as-asset argument pushed back up the supply chain to the factory.

McKinsey estimates that a set of ten themes and forty-nine named technologies represents “a $600 billion to $1 trillion addressable market by 2030,” which their authors define as forecast spending on equipment and infrastructure plus projected software and services revenue. That is a scoping decision, not a measured market. It is McKinsey’s estimate of an addressable market, not the size of an industry.

Force three: deliverability becomes a product feature. The events themselves, plus the tariffs and shipping constraints tracked all month, reward materials and supply chains that are regional, substitutable, and resilient. The next great building material may win less on raw performance than on whether it arrives on schedule when a canal is throttled or a tariff lands.

Running underneath all three is the digitization of the material itself. Mass timber arrives with a fabrication record. Low-carbon concrete arrives with a documented mix design and an environmental product declaration. That data layer lets a regulator, an underwriter, and a buyer read the same building from the same record, and documentation is exactly what a carrier needs before it will reward anything.

The Next Chapter

Over the next decade, building science becomes the competitive front in real estate, and the mechanism is exclusion rather than premium.

The supplier who controls a low-carbon, resilient, code-compliant material will not be selling a premium product. They will be selling the only compliant one. Conversely, the high-carbon or unrated product becomes stranded inventory, designed out of projects the way an uninsurable asset gets designed out of a portfolio.

For a century the cheapest-to-build material won, and durability and carbon were somebody else’s problem - the insurer’s, the next owner’s, or the planet’s. The revolution closes that gap only where carbon and performance are both measured, priced, and required. Take the requirement away, and the externality goes straight back out of the balance sheet.

So the firm that sees this early does not bet on regulation. It bets on the two forces that do not reverse. Physics does not reverse. A building that survives a 14.7-foot surge survives it under any administration. And insurance does not reverse. A carrier writing a coastal risk cares about the roof deck attachment, whatever the procurement rules say.

The question to leave with builders, suppliers, and the investors who back them is this. Are the materials sitting in your portfolio right now on the right side of the building-science revolution, or one code cycle away from obsolescence?

The revolution does not announce itself with a breakthrough or a ribbon-cutting. It shows up as the slow re-sorting of which materials, methods, and firms are still allowed in the building at all.

The house at Mexico Beach already told us the ending. Survival is a choice made at the spec stage. The only open questions are whether you will make it low-carbon, and whether you will make it before the market insists.

Federal low-embodied-carbon procurement — $2.15 billion appropriated, with $2.003 billion assigned to 154 projects covering asphalt, concrete, glass, and steel; $767 million obligated by January 31, 2025; disbursements on hold from February 13, 2025; the authorizing section repealed and unobligated balances rescinded in July 2025

US Government Accountability Office, GAO-25-107349 and General Services Administration, low-embodied-carbon projects fact sheet · Data as of Jan 31, 2025 · Published Nov 3, 2023 and Apr 29, 2025 · Accessed Aug 2026

The Environmental Protection Agency’s $250 million environmental product declaration assistance fund was repealed in the same act. The technical material requirements still govern projects obligated before the freeze. The $2.15 billion is the Inflation Reduction Act appropriation to the General Services Administration to acquire and install low-embodied-carbon materials. The $1.38 billion is derived by subtracting the $767 million obligated by January 31, 2025, from that allocation; neither cited document states a rescinded amount directly.
