The Property Insurance Retreat: Florida, California, and the Climate Repricing of US Real Estate

California: State Farm, Allstate, and the FAIR plan growth #

State Farm General Insurance, the largest homeowners insurer in California with roughly 21 percent of the market, announced in May 2023 that it would stop accepting new homeowners applications in the state. In March 2024 it announced non-renewals for approximately 72,000 existing policies, including 30,000 homeowners policies concentrated in wildfire-exposed ZIP codes. The California Department of Insurance approved an interim 22 percent rate increase for State Farm General in May 2024, conditioned on a USD 400 million capital infusion from State Farm Mutual. A subsequent rate increase to a cumulative 30 percent above the 2023 baseline was approved on appeal in early 2025. Allstate had already stopped writing new California homeowners policies in November 2022.

California's FAIR plan, the residual market mechanism for high risk properties, grew from roughly 200,000 policies in 2018 to 555,000 by September 2024 according to the FAIR Plan Association quarterly disclosures. The total insured value rose past USD 460 billion. The FAIR plan paid out roughly USD 4 billion in claims following the January 2025 Eaton and Palisades fires, against a surplus that pre-fire stood near USD 700 million. The shortfall was filled by mandatory assessments on admitted carriers, with statutory authority for the Insurance Commissioner to apportion losses across all California-licensed property and casualty insurers. The Sustainable Insurance Strategy issued by Commissioner Lara in December 2024, which permits forward-looking catastrophe modeling and conditional rate adequacy in exchange for high risk policy commitments, is the regulatory pivot the market had asked for since the 1988 Proposition 103 framework.

Florida: Citizens at 1.4 million, the depopulation push, and the litigation reform #

Florida's Citizens Property Insurance Corporation, the state-backed insurer of last resort, grew from roughly 420,000 policies in 2018 to a peak of 1.41 million in November 2023 as private carriers withdrew or became insolvent. The Office of Insurance Regulation supervised insolvencies of FedNat, Lighthouse, Southern Fidelity, UPC, Avatar, and Bankers in the 2021 to 2023 cycle. Senate Bill 2A, signed December 2022, restructured the assignment of benefits regime, eliminated one-way attorney fees, and extended Citizens reinsurance support. Senate Bill 7052, signed May 2023, layered additional consumer protections and tightened public adjuster rules. The litigation reform allowed admitted carriers to contemplate Florida re-entry by 2025.

Citizens executed depopulation rounds in 2024 and 2025 that moved roughly 350,000 policies to private carriers, including new entrants Slide Insurance, Vyrd, and Manatee. Residual Citizens policy count fell to roughly 850,000 by year end 2025. Reinsurance pricing improved year over year in the June 1 2024 and June 1 2025 Florida renewal cycles, with the Florida Hurricane Catastrophe Fund retention layer easing as cumulative reserve fund built. The market remains fragile: the 2024 hurricane season delivered Helene and Milton with combined insured losses near USD 50 billion per Aon and Swiss Re estimates, the highest insured loss season since 2017. The reform held; the catastrophe load did not test it past the breakpoint.

The reinsurance hardening: Swiss Re, Munich Re, and the retro layer #

Global property catastrophe reinsurance pricing rose sharply at the January 2023 renewal cycle and continued at elevated levels through January 2025 and the June 1 2025 Florida renewal. Guy Carpenter's global property catastrophe rate-on-line index registered a roughly 35 percent rise in 2023 followed by smaller increases in 2024 and 2025; Howden Re's global retrocession index registered a sharper rise. The drivers were a multi-year run of catastrophic losses (Hurricane Ida 2021, the European floods 2021, the Turkey earthquake 2023, Hurricane Ian 2022, the Maui wildfires 2023, the January 2025 California fires), retrocession capacity withdrawal as ILS and sidecar capital reset terms, and a recalibration of US severe convective storm models after multi-billion-dollar tornado, hail, and derecho seasons in 2023 and 2024.

Swiss Re reported its property and casualty reinsurance segment combined ratio at 84 percent in 2024 against a 5-year median near 100, reflecting the hardened pricing and benign catastrophe distribution. Munich Re reported a similar pattern. The mid-cycle question, posed at the Monte Carlo Rendez-Vous in September 2025, is when the rate-on-line reset begins to soften. Property reinsurance remains the most disciplined segment in the cycle, with cedents and reinsurers alike still aware of the post 2017 to 2018 false-bottom that gave back gains too quickly. Cedent retentions remain at multi-decade highs.

The non-renewal pattern beyond the headline states #

North Carolina's Beach Plan and Coastal Plan together insure roughly 250,000 properties for wind and storm risk, with cumulative exposure past USD 80 billion. The North Carolina Rate Bureau filed for a 42 percent statewide homeowners rate increase in early 2024; the Department of Insurance reached a settlement at 15 percent staged through 2026. Louisiana lost approximately 15 percent of its homeowners market between 2020 and 2023 to insolvency or withdrawal following hurricanes Laura, Delta, and Ida. The state Insure Louisiana Incentive Program, which provides matching grants to admitted carriers writing new business, has attracted roughly USD 80 million in commitments through 2025. Colorado, after the December 2021 Marshall fire that destroyed approximately 1,000 structures, has seen carrier withdrawal in the wildland urban interface mountain counties.

Texas, the largest US homeowners market by premium, has remained better supplied than the headline retreat states but shows pressure on the wind-storm-belt. The Texas Windstorm Insurance Association, which insures coastal Tier 1 and parts of Tier 2 for wind and hail, carried roughly 250,000 policies and USD 100 billion of insured value at year end 2024 against a Catastrophe Reserve Trust Fund near USD 600 million. The 2024 reauthorization debate moved through the Texas Sunset Commission. Hawaii's Lahaina insurance recovery, after the August 2023 wildfire, has surfaced subrogation claims against Hawaiian Electric that exceed the company's market capitalization. The pattern in each case is the same: catastrophe loss frequency outruns underwriting margin, residual mechanisms absorb the displaced demand, and rate adequacy litigates.

Climate repricing on real estate values and mortgage credit #

The First Street Foundation 2024 Property Risk Report estimates that climate insurance repricing will reduce US residential property values by USD 1.47 trillion in net present value through 2055, with a disproportionate concentration in coastal Florida, the California wildland urban interface, and the Gulf Coast. Federal Reserve Bank of San Francisco research and Federal Reserve Board working papers have begun to incorporate insurance non-renewal as a credit channel. Fannie Mae and Freddie Mac require force-placed coverage if a borrower's policy lapses, with premium markups that reduce post-tax income. The conforming mortgage 30 year fixed rate gap between high-climate-risk ZIP codes and matched control ZIP codes has begun to widen in micro-data from the Home Mortgage Disclosure Act 2023 and 2024 vintages.

The political question is whether federal climate adaptation finance, including the National Flood Insurance Program reauthorization (perpetually extended through short-term continuing resolutions) and the proposed Climate Resilience Block Grant under the Bipartisan Infrastructure Law, scales fast enough to underwrite the residual mechanism's growth. Citizens, FAIR, the NCJUA, and TWIA together carry insured value past USD 1 trillion, with statutory authority to assess private carriers if reserve funds fail. The implicit federal backstop, never quite formalized, is the elephant in every state insurance commissioner's office. Sisyphus models the assessment-cascade probability under three catastrophe scenarios; Argus tracks carrier filings, M and A activity, and the residual mechanism balance sheets.

Implications for insurers, lenders, real estate, and policy #

For admitted insurers, the Florida re-entry cycle and the California Sustainable Insurance Strategy have repriced two of the three largest state markets. The new entrant insurtech model (Slide, Vyrd, Kin Insurance, Branch Financial) trades scale for selectivity, leveraging granular property attribute data and conditional underwriting at the parcel level. The legacy carriers that retained presence (Travelers, Liberty Mutual, Chubb, Farmers in select segments) face the question of whether higher rate adequacy is sustained across the next catastrophe cycle. For mortgage lenders, force-placed coverage volume and origination concentration in high climate risk geographies are first-order risk metrics. For real estate, the cap rate adjustment to insurance cost growth is most visible in coastal Florida and California urban-wildland-interface, where buyer search has begun to reweight away from fire and storm exposed parcels.

For reinsurers, the soft cycle entry point has been deferred at every renewal since January 2023. ILS and catastrophe bond issuance reached records in 2024 and 2025, signaling capital wants in at current spreads but is not yet pressuring discipline. The mid-cycle inflection will likely be triggered by a benign 2026 to 2027 catastrophe distribution and the willingness of one large reinsurer to lead a softening. For policy, the federal question is whether the NFIP reform, the Climate Resilience Block Grant scaling, and the implicit residual mechanism backstop are formalized through legislation or remain ad hoc. The insurance industry has run the climate repricing further than any federal climate policy has authorized; whether that holds is a 2027 to 2030 question.
