US homeowners insurers swung from a $1.3 billion net underwriting loss in 2024 to a $16.5 billion gain in 2025, the line's first annual underwriting profit since 2019, on a net combined ratio of 87.8 improved from 99.2 (AM Best, September 2026). Almost $4.1 billion of favorable prior-year development sits inside that result, worth 2.5 points of the calendar-year combined ratio, so the 2025 accident year on its own closed near 90.
AM Best's segment report, "A Myriad of Factors Lead to Markedly Improved Homeowners Results," reached the trade press at the end of September and anchors Insurance Journal's October 19 feature on the segment. Five groups, USAA, American Family, Liberty Mutual, Chubb and RenaissanceRe US, booked about 47% of the release, more than $1.9 billion, and AM Best ties a share of it to Florida's 2022 and 2023 tort reforms. No hurricane made US landfall in 2025. Isaias has already changed that for 2026.
Key Takeaways
- 2.5 points of the 87.8 calendar-year combined ratio came from almost $4.1 billion of favorable prior-year development on the homeowners and farmowners multiperil line, which AM Best calls unusual at this scale for a short-tail line.
- 47% of that release, more than $1.9 billion, was booked by five groups, so the industry figure is a concentrated event at a handful of national and Florida-exposed writers rather than a broad redundancy across the line.
- 13.5% to 7.6% to 4.3%: the average approved homeowners rate increase fell across 2024, 2025 and the first half of 2026, with Florida's dropping from 5.7% to 0.5%, so the premium base that absorbed 2025's losses is now growing on a fraction of the earlier rate action.
- 48.4: the industry's direct incurred loss ratio for homeowners through June 2026 was the lowest first-half reading in five years, before the third quarter's central US hail and the first hurricane landfall of the season.
- 61.5 against 94.6: Allstate's second-quarter homeowners underlying combined ratio rose 2.9 points on higher loss costs while the reported figure improved eight points on lower catastrophes, the same calendar-year versus underlying gap AM Best's industry number carries.
The Release Inside the Calendar Year
AM Best's calendar-year combined ratio series runs 110.9 in 2023, 99.2 in 2024 and 87.8 in 2025, with a 2025 net loss and loss adjustment expense ratio of 61.1 (IA Magazine, October 2026). The $4.1 billion of prior-year development enters that 61.1 directly: it is a reduction in incurred losses for accident years 2024 and earlier, booked in the 2025 calendar year. Strip it out and the accident-year combined ratio is about 90.3, which is still 8.9 points better than 2024 and the best figure in the series by a wide margin.
Dividing $4.1 billion by 2.5 points implies roughly $164 billion of net earned premium, which is the denominator every other figure in the report shares. On that base the $16.5 billion underwriting gain is about 10 points of premium, and the $1.3 billion loss of 2024 was under one point. The line did not move from a small loss to a large gain on the strength of one benign catastrophe year alone; it moved on rate earned in from 2022 to 2024, a quiet hurricane season and a reserve release that is worth a quarter of the swing.
The concentration is the detail that locates the release. Five groups booked 47% of it (Insurance Journal, September 2026), and AM Best links the Florida portion to the tort reforms of December 2022 and March 2023, which cut property lawsuit filings and let insurers lower reserves on open Florida claims. Florida's 2025 loss and LAE ratio and combined ratio both fell sharply from each of the two prior years and were the lowest of any top-ten state by a wide margin. The site traced the same litigated-inventory runoff in the Florida OIR stability report, where lawsuit share fell to 41%.
Why a Short-Tail Line Released $4.1 Billion
Homeowners reserves at a December 31 valuation are mostly case reserves on open claims from the last two accident years plus IBNR on the latest catastrophe events. A release of this size on that inventory means the case estimates and the catastrophe IBNR carried at the end of 2024 were set against a severity and litigation environment that 2025 settlements did not reproduce. Florida is the clearest instance: a claim reserved in 2022 with a one-way attorney fee exposure settles in 2025 under a statute that removed the fee, and the difference is released.
The second mechanism is the earned-premium lag the site set out in September's approved-rate analysis. Approved increases averaged 13.5% in 2024 and 7.6% in 2025 (Insurance Business, September 2026), and an annual policy approved in mid-2024 is still earning at the new rate through mid-2025. The 2025 calendar year earned the full weight of two years of double-digit filings against a loss year with no hurricane landfall. AM Best's own framing credits a third factor: property catastrophe reinsurance pricing peaked in 2023 and has softened at every renewal since, with Howden Re measuring the January 2026 risk-adjusted decline at 14.7% (Reinsurance News, September 2026).
Carrier results through 2026 show the three factors separating. Allstate's second-quarter homeowners combined ratio improved to 94.6 from 102 a year earlier on catastrophe losses down 12.8% to $1.4 billion, while the underlying combined ratio rose 2.9 points to 61.5 on higher loss costs (Allstate, July 2026). Travelers' Personal Insurance segment ran 83.5 in the third quarter against 81.3 a year earlier, with catastrophes adding 9.2 points, mostly central US tornado and hail, on net written premium down 7% (Travelers Form 8-K, October 2026).
For a pricing actuary the consequence is in the indicated rate. An experience period that includes 2025 carries a calendar-year loss ratio flattered by 2.5 points of release and a catastrophe load from a year with no landfall. Both belong outside the indication: prior-year development is removed by restating the period on an accident-year basis, and the catastrophe provision comes from the modeled load rather than the 2025 actual. A filing built on the reported 61.1 instead of the accident-year ratio understates the indication by about three points before the catastrophe adjustment, and the approved increases now running at 4.3% leave no room to recover that.

The Litigated Inventory Behind the Release Is a One-Time Draw
The Florida portion of the $4.1 billion is a one-time conversion. Every claim reserved under the pre-2023 fee statute and settled under the post-2023 one releases its litigation margin once, and the inventory of such claims shrinks with each settlement. Accident years 2024 and 2025 were reserved under the reformed regime from the start, so their case estimates carry no comparable margin to give back. The Universal second-quarter result, a 33.2% adjusted return on capital alongside rate give-backs, shows where that cycle lands: the saving is passed into the 0.5% approved increase rather than retained.
The catastrophe side has already turned. Isaias made landfall near Destin on October 9 as the first hurricane of 2026, with insured loss estimates from $1 billion to $4.5 billion across Verisk, Cotality, KCC and Moody's RMS, and AM Best calling it an earnings event (AM Best, October 2026). The site's Isaias analysis put the Panhandle exposure in context. Add Travelers' $538 million of third-quarter catastrophes from hail alone and the 48.4 first-half loss ratio will not survive the year.
Rate filings slowed first. AM Best reports that filings for increases fell off in the second half of 2025 and kept falling through the first half of 2026, so the premium base entering 2027 grows at 4.3% approved against loss costs that Allstate's underlying ratio shows rising about three points a year. The 2025 result was built by two years of double-digit rate, a landfall-free season and a litigation runoff, and each has now been spent, reversed or passed back to policyholders. The 87.8 is the ceiling of the cycle, and the release that supplied 2.5 points of it came from accident years no new filing can restock.
