That matters far beyond insurers: where you can't insure a home, you often can't mortgage it, and that chain reaches into property values, bank balance sheets and financial stability. A quiet but consequential strain is building under the world's housing markets: insuring a home against the weather is getting more expensive, and in the most exposed places it is becoming impossible. What looks like an insurance-industry story is really an economy-wide one. ## The math is breaking down Insurers price risk by looking at the past. Climate change is making the past a poor guide: floods, storms and wildfires are striking harder and more often than old models assumed. The result is a run of very costly years — global **insured** losses from natural catastrophes have topped roughly **$100 billion a year for several years running**, according to the [Swiss Re Institute](https://www.swissre.com/institute/research/sigma-research/sigma-2025-01.html), which has warned that rising exposure and risk will keep pushing prices up. Reinsurers such as [Munich Re](https://www.munichre.com/en/company/media-relations/media-information-and-corporate-news/media-information/2026/natural-disaster-figures-2025.html), which insure the insurers, report that a large share of total disaster damage each year is **not** insured at all. ## The 'protection gap' That uninsured slice has a name: the **protection gap** — the difference between total losses from a disaster and the portion someone had insured. It is widest in poorer countries, where the bulk of catastrophe losses fall on households and governments rather than insurers. But it is now opening up in rich economies too, as insurers raise premiums sharply or pull out of high-risk regions entirely — stretches of wildfire-prone California, flood-prone England, hurricane-exposed Florida — leaving owners scrambling for cover. ## Why this reaches the whole economy Here is the chain that turns an insurance problem into an economic one. Mortgage lenders require buildings insurance as a condition of the loan. If a property can't be insured affordably, a buyer often can't get a mortgage on it — which means fewer buyers, falling values, and homeowners stuck with assets they can't sell at the price they expected. Whole neighborhoods can be repriced by the withdrawal of cover. Banks feel it next. They hold those mortgages on their balance sheets, so when insurance retreats from a region, the credit risk on the loans there rises. This is why central banks have started treating climate as a financial-stability issue, not just an environmental one: the [Bank of England](https://www.bankofengland.co.uk/climate-change) now expects banks and insurers to **stress-test** their exposure to climate scenarios — modeling how repeated floods or storms would hit their capital. ## The reinsurance ratchet Premiums for households are driven, ultimately, by **reinsurance** — the cover insurers buy to protect themselves against catastrophic years. As claims mount, reinsurance gets scarcer and pricier, and insurers pass that cost down the line. It is a ratchet: each bad season feeds into the next year's prices, and the increases concentrate exactly where the risk is highest. ## Backstops, and their limits Governments have built stopgaps. Britain's **Flood Re**, running since 2016, is a pool funded by a small levy on all home policies that subsidizes cover for flood-prone houses — but it is designed to wind down by **2039**, on the assumption that the market can take over by then, a deadline that looks increasingly optimistic. The United States leans on the federally backed National Flood Insurance Program, itself repeatedly in deficit. These schemes spread the cost; they don't make the underlying risk go away. ## The bottom line The insurance industry can reprice risk — that is its job. What it struggles with is risk that no longer behaves predictably, which is precisely what a warming climate delivers. Left unaddressed, the danger is a slow feedback loop: rising premiums and shrinking cover depress property values and tighten lending in exposed areas, which weakens local economies and, at the extreme, the financial system that underwrites them. The cost of climate change, in other words, is already showing up on insurance renewal notices — and from there it spreads. ## Sources - [Natural catastrophes and insurance losses](https://www.swissre.com/institute/research/sigma-research/sigma-2025-01.html) - [Climate change: what are the risks to financial stability?](https://www.bankofengland.co.uk/climate-change)
