Typically, the renewal letter comes in a plain envelope. A few paragraphs of legalese, a blue logo, white paper, and the new number somewhere on the second page. That number was dull for a while. Like property taxes, it increased by a few percent annually, and the majority of homeowners signed it without giving it any thought. That is no longer true. The envelope has begun to feel like something completely different in Tampa, Pacific Palisades, and some areas of the Texas Gulf—a judgment on whether you can still afford to live where you live.
Although the change took time, it happened more quickly than anyone in the industry seems willing to acknowledge. Since 2019, the cost of homeowners insurance in the United States has increased by about 38%, with some areas seeing much larger increases. The average annual premium in Florida is currently about $15,000, which is more than three times the national average—that is, if a private carrier is willing to write the policy at all. For years, national insurers have been quietly pulling out of the state. Six of them simply filed for bankruptcy following Hurricane Ian in 2022, and the public Citizens program took up the excess, unintentionally becoming Florida’s biggest insurer.

Reinsurers have begun to use the term “the new normal” almost casually. Years with insured catastrophe losses exceeding $100 billion are now described by Swiss Re as the norm rather than the exception. The sixth year in a row above that threshold was 2025. However, the character of the losses is just as remarkable as their magnitude. Although hurricanes continue to garner media attention, approximately 92% of last year’s insured catastrophe losses were caused by what the industry refers to as secondary perils, such as urban floods, hailstorms, and wildfires, which were previously priced as background noise. The Los Angeles wildfires alone caused insured damage estimated at forty billion dollars, making it the biggest wildfire incident Swiss Re has ever documented.
Insurance companies are reacting just like any other company under duress. They are requesting larger deductibles, tightening terms, increasing prices, and completely avoiding the worst exposures. Speaking with industry insiders gives the impression that the outdated method of pricing using past loss data is no longer viable. Not much is predicted by the past these days. Underwriters are uncomfortable with the results of models that now predict warming trajectories, soil moisture, vegetation dryness, and building codes. Some of these models might be overly pessimistic. They might also not be sufficiently pessimistic. No one seems to know.
It is more difficult to depict this in a chart at the kitchen table level. After the fires, a retiree in Paradise, California, is now paying more in premiums than in property taxes. A Cape Coral family decides between insurance and groceries, so they let their policy expire. Low-income homeowners are particularly price-sensitive, according to research from Brookings; when premiums rise, they don’t shop around; instead, they simply cut back on coverage and bear the risk. As this develops, it’s difficult to ignore how subtly a private financial product has begun to carry out the duties of public policy, creating imperceptible boundaries that allow neighborhoods to continue serving as places to live, inherit, and age.
It’s unclear where this lands yet. If mortgage lenders begin pricing climate exposure the same way insurers do, some economists fear a slow-motion housing crisis. Others think that after carriers have finished recalibrating, the market will stabilize. In any case, the renewal envelope is no longer tedious. A yearly reminder that the climate, whatever else it is doing, is now showing up in the mail, it has become one of the more honest documents that the average household receives.
