Private Insurance Can't Price Climate Disaster

Climate risk isn't just an environmental problem. It's threatening the future of private insurance and housing affordability.

According to a recent report by Coalition for an Insurable Future and Mandala Partners, homeowners' insurance premiums have increased 38% since 2021, growing faster than both inflation and wage growth. In some places, like Florida, these rates have increased by 75% since 2021.

Climate change doesn’t only become expensive after a hurricane destroys a neighborhood or a wildfire burns through a town. The financial consequences begin far before these disasters strike, and insurance companies exist to price risk. As climate change makes natural disasters more frequent and severe, private insurance markets are struggling to operate profitably.

Evidence already shows rising premiums, higher non-renewal rates in high-risk areas, insurer withdrawals, and growing pressure on taxpayers and public backstops. This isn’t just an insurance problem. It’s an economic warning sign that housing markets, public finances, and economic stability are becoming increasingly vulnerable.

The Crisis is Already Here

The insurance industry is quietly changing across the nation. Homeowners in Louisiana, California, and Florida have watched premiums rise dramatically, while some insurers have stopped writing new policies or left the market entirely. Others have chosen not to renew existing policies, leaving families scrambling for alternatives.

This is a reaction to losses, uncertainty, and rising reinsurance costs. The U.S. Department of the Treasury found that in 2018-2022, homeowners in the highest-risk ZIP codes paid far more on average than those in the lowest-risk ZIP codes, and nonrenewal rates were about 80 percent higher in the riskiest areas. According to recent reports, insurance premiums in Florida could rise between 33% and 75% by 2035, and in South Carolina, rates could increase by up to 200%. And this is not just a worry for our future; the effects are already visible, with wildfire threats spiking California home insurance costs by 84% over the past 5 years. This is a warning that risk is concentrating faster than the private market can comfortably absorb.

Who Takes the Fall?

The problem is that insurance is supposed to spread risk, not abandon it. When coverage becomes too expensive or impossible to buy, the consequences extend far beyond a single homeowner. Mortgage lenders require insurance, so housing becomes harder to buy and sell, property values weaken, and local governments lose tax revenue. Families get trapped in places they cannot afford to protect, while businesses back out of investing in regions where climate losses keep rising.

The retreat of private insurers shifts the risk rather than eliminating it. State-backed plans such as Florida’s Citizens and California’s FAIR Plan show that the government becomes the insurer of last resort when markets pull back. That may be necessary, but it also means taxpayers are increasingly covering climate losses that the private market no longer wants to bear. We are socializing the cost of climate damage without adequately reducing the damage itself. That is the real warning. Climate change is not just making disasters worse; it is making large parts of the economy harder to insure, finance, and maintain. Policymakers can’t just treat rising premiums as a nuisance instead of a crisis signal, or else they will wake up to a deeper problem: neighborhoods that are functionally unfinanceable, financially overextended governments, and families left holding the bill for risks they never created.

Potential Solutions

We cannot just subsidize risk — we must make efforts to reduce it. That means states should prioritize making homes less likely to be damaged in the first place. Wind-resistant roofing, fire-resistant siding, hail-resistant shingles, and similar upgrades can reduce losses enough to justify broader adoption, especially when paired with code requirements for new construction. EIOPA also notes that insurers can lower premiums for policyholders who implement adaptation measures like flood doors or early warning systems. Public insurance backstops do not solve the underlying math if disasters keep getting worse. Broad subsidies in high-risk areas can blur the real price of living in harm’s way and push more exposure onto households elsewhere. That makes subsidies a bandage on a bullet hole.

Climate risk could push home insurance premiums up by 107% by 2050 if action isn't taken. The best solution to curb these rates is to fortify infrastructure. If policymakers want to prevent insurance premiums from skyrocketing further, they should focus on helping homeowners retrofit roofs, siding, windows, and other weak points so that houses are less likely to suffer major losses in the first place. A stronger building stock lowers claims, makes insurers more willing to stay in high-risk markets, and gives families a real chance to keep coverage without forcing taxpayers to absorb the full cost of repeated disasters.
