The U.S. property and casualty (P&C) insurance industry wrote <\/span>$975.8 billion<\/b> in net premiums in 2025, up 5% year over year, and posted a net combined ratio of <\/span>92.9<\/b>, its lowest in more than a decade. The net underwriting gain roughly tripled to about <\/span>$63 billion<\/b>. These property and casualty insurance industry statistics, drawn from <\/span>AM Best,<\/span><\/a> NAIC,<\/span><\/a> Verisk and APCIA,<\/span><\/a> and <\/span>Triple-I and Milliman data,<\/span><\/a> show an industry that consolidated its recovery in 2025, helped by the first Atlantic hurricane season in 10 years with no U.S. landfall.\u00a0<\/span><\/p>\n Below are the numbers that matter for 2026, organized by market size, profitability, catastrophe exposure, line of business, and the largest carriers.<\/span><\/p>\n Based on full-year 2025 results and first-quarter 2026 data:<\/span><\/p>\n A combined ratio below 100 means an insurer paid out less in claims and expenses than it collected in premiums. At 92.9, the 2025 result clears that mark by more than 7 points.\u00a0<\/span><\/p>\n The U.S. P&C market is measured most reliably by premiums, and net premiums written reached <\/span>$975.8 billion<\/b> in 2025, up 5%, <\/span>according to AM Best<\/span><\/a>. On a direct basis, <\/span>AM Best puts 2025 direct premiums written by line<\/span><\/a> at <\/span>$1.11 trillion<\/b>, also up 5%.\u00a0<\/span><\/p>\n Globally, estimates vary by research firm because of differing definitions and currency assumptions. <\/span>Swiss Re Institute puts the global P&C market at about <\/span>$2.4 trillion<\/b><\/a>, having doubled over the past 20 years, and forecasts global non-life real premium growth at a <\/span>cyclical low of 0.6% in 2026<\/span><\/a> before a modest recovery to about 1% in 2027. Commercial research houses publish figures several times larger on broader definitions. For anything you need to defend, use Swiss Re, NAIC or AM Best.<\/span><\/p>\n Two forces drove premium growth through 2024 and into 2025: multi-year rate increases catching up to inflation-driven loss costs, and rising insured values in homes, vehicles, and commercial property. Both are now fading. Growth slowed to 5% in 2025 from 8.7% in 2024, and<\/span> to 2.9% in the first quarter of 2026.<\/span><\/a>\u00a0<\/span><\/p>\n 2025 was the industry’s best underwriting year in over a decade. The net combined ratio of <\/span>92.9<\/b> was a <\/span>3.7 point improvement on 96.6 in 2024,<\/span><\/a> and the largest underwriting profit in ten years.\u00a0<\/span><\/p>\n Profitability improved across most of the market:<\/span><\/p>\n Personal lines drove the turnaround. Personal auto improved again in 2025, to a net combined ratio of <\/span>91.8<\/b>, 3.5 points better than 2024. Homeowners posted <\/span>88.1<\/b>,<\/span> its strongest underwriting performance in more than ten years<\/span><\/a>, even after the January 2025 Los Angeles wildfires. Commercial lines stayed profitable, and the gap with personal lines narrowed further.\u00a0<\/span><\/p>\n The takeaway for 2026: the profit is real, but it was weather-assisted.<\/span> Verisk and APCIA<\/span><\/a> attribute the 2025 result more to unusually low catastrophe losses than to any structural shift in risk. Rate increases have now turned into rate decreases, and<\/span> Triple-I and Milliman<\/span><\/a> forecast a 3.7% contraction in underlying P&C growth in the first half of 2026.\u00a0<\/span><\/p>\n Catastrophe losses remain the single biggest swing factor in P&C results. In 2025 they cost the industry 7.6 points of combined ratio,<\/span> down from 8.8 points in 2024<\/span><\/a>. That 1.2 point swing is most of the year’s improvement, which is why the profit is better read as a quiet year than as a new baseline.\u00a0<\/span><\/p>\n The January 2025 Los Angeles wildfires drove $33.3 billion of catastrophe losses in the first quarter of 2025 alone, 14.5 points of combined ratio. Then the Atlantic hurricane season produced no U.S. landfall,<\/span> the first time in 10 years<\/span><\/a>. That combination, a severe first quarter followed by a quiet second half, is what produced the year’s result.<\/span> First-quarter 2026 catastrophe losses fell to $10.0 billion<\/span><\/a>, or 4.2 points.<\/span><\/p>\n Homeowners is the clearest illustration. Its 2025 net combined ratio came in at 88.1,<\/span> the best in more than ten years<\/span><\/a>, and yet the line absorbed the largest single wildfire loss in U.S. history in the same year. Catastrophe volatility, not day-to-day claims, is what moves property margins, in both directions. <\/span><\/p>\n Personal auto is the largest single line, and its scale shapes the whole industry’s numbers.<\/span><\/p>\nProperty and Casualty Insurance Industry Statistics: Key Numbers (2026)<\/b><\/h2>\n
