The US property-casualty industry posted a combined ratio of 89.5 before policyholder dividends in Q1 2026, the lowest first-quarter figure since at least 2001, on $22.1 billion of net underwriting gains. S&P Global Market Intelligence published the aggregation in late May.

The number behind it sits in one line. Homeowners multiperil went from a 102.3 direct incurred loss ratio to 44.3, a 58-point swing that carries roughly two-thirds of the improvement.

Key Takeaways

  • 89.5 combined ratio on about $247 billion of net earned premium, producing $22.1 billion of underwriting gain against $10.2 billion in Q1 2024 and an inflation-adjusted $14.2 billion in Q1 2006.
  • 102.3 to 44.3 in homeowners, the difference between a quarter carrying the Los Angeles wildfires and one with global insured catastrophe losses of $20 billion, 47% below the five-year average.
  • Roughly 55 is where the homeowners loss ratio would sit on average catastrophe activity, which puts the industry combined ratio nearer 93 to 94 than 89.5.
  • 65.8 in other liability is the worst first-quarter reading in 24 years, and commercial auto liability rose 3.2 points to 71.1 in the same quarter.
  • 96.9 full-year is AM Best's projection, with Fitch at 96% to 97% and S&P Global at 96% to 98%, all roughly 7 points worse than the quarter.

What Produced the Number

Two lines carry almost all of it, and they got there by different routes.

Metric Q1 2026 Q1 2025 Change
Combined ratio (ex-dividends) 89.5 ~97 Improved ~7.5 pts
Combined ratio (incl. dividends) 91.9 ~98 Improved ~6 pts
Net underwriting gain $22.1B ~$6B +$16B
Dividend ratio 2.4 ~1.0 +1.4 pts
Homeowners loss ratio 44.3 102.3 Improved 58.0 pts
Private auto loss ratio 60.4 61.0 Improved 0.6 pts
Commercial auto loss ratio 71.1 67.9 Deteriorated 3.2 pts
Other liability loss ratio 65.8 — Highest Q1 in 24 years

Homeowners is the swing. Q1 2025 was dominated by the Los Angeles wildfire complex, which pushed State Farm to a first-quarter underwriting loss above $5 billion; the same carrier posted roughly a $2 billion gain in Q1 2026, a turnaround above $7 billion on its own. Gallagher Re put global insured catastrophe losses at $20 billion for the quarter, 26% below the 10-year average and 47% below the five-year, with severe convective storm activity starting later than usual.

Personal auto contributed differently. Its 60.4 loss ratio was only 0.6 points better than a year earlier but 15.4 points better than Q1 2023, because the rate increases that began in late 2022 had already earned through by the year-ago quarter. All seven of the largest personal auto writers cleared $1 billion of underwriting gain, with Progressive at an 86.4 companywide combined ratio on 9% policies-in-force growth.

The dividend line is worth noting alongside. At nearly 2.4 it was the second-highest in the 25-year series, driven by State Farm distributing $5 billion and USAA $4 billion, so the 91.9 including-dividend figure sits below the underwriting margin a stock-only universe would show.

Separating the Rate From the Weather

The pricing question is how much of the 89.5 survives a normal loss environment, and the components pull apart cleanly enough to answer it.

Rate adequacy is real and durable. Cumulative personal auto increases of 30% to 40% between 2022 and 2025 restored margins to levels last seen in the early 2010s, homeowners rose 20% to 35% in catastrophe-exposed states, and workers' compensation is in its 12th consecutive year below 100. None of that reverses in a quarter.

The weather component is equally identifiable, and it is the part a rate filing can misuse. The long-term first-quarter average for homeowners direct incurred losses is 54.7, so at 44.3 the quarter ran more than 10 points below its own favorable baseline. Rebuild the industry ratio with homeowners near 55 and the 89.5 becomes roughly 93 to 94. That is the figure a catastrophe load or a trend selection should be anchored to, because a quarter running 47% below the five-year average catastrophe loss is by construction not the expected loss environment.

Three rating agencies converge on the same conclusion from the other direction. AM Best projects 96.9 for the full year, Fitch 96% to 97%, S&P Global 96% to 98%, all expecting catastrophe normalization, competition and casualty deterioration across the remaining quarters. Splitting the difference, structural rate adequacy explains around 3 to 4 points of the improvement against the pre-hard-market baseline and favorable weather and timing another 3 to 4, which puts a normalized run rate in the 93 to 95 range: profitable, and not a record.

Competition is already arriving. Net premium growth turned negative at -3.7% for H1 2026 against 6.1% in 2025, commercial premiums fell 1.2% in the CIAB survey, the first decline since 2017, and nine commercial lines recorded decreases led by commercial property at -5.5%.

What Is Building Under the Headline

Casualty is moving the other way, and its development lag is longer than the reporting cycle that produced the record.

Other liability posted a 65.8 loss ratio, the highest first-quarter reading in 24 years, and commercial auto liability rose 3.2 points to 71.1 in a line that has now recorded 14 consecutive years of underwriting losses. AM Best estimates a $4 billion to $5 billion reserve shortfall in commercial auto alone, Swiss Re has put cumulative industry casualty under-reserving at $62 billion, and Milliman's 2024 year-end data showed a record $15.8 billion of casualty adverse prior-year development. CNA gave a live example in the same quarter: $106 million of unfavorable casualty development, $56 million in excess casualty and $50 million in professional E&O, taking its P&C combined ratio to 102.2%.

The calendar-year figure nets those movements against favorable development on recent property years, so a 89.5 combines current property strength with older casualty vintages that are still developing. The accident-year view is what separates the two, and the historical lag between casualty rate inadequacy and calendar-year deterioration runs 18 to 24 months, which places the visible consequence of Q1 2026's casualty reading in late 2027 or 2028.

Investment income works in the same direction rather than against it. Chubb reported record pretax net investment income of $1.71 billion, up 9.5%, and Progressive's $97.4 billion portfolio is producing $4.3 billion annualized. A carrier earning 4% to 5% on float can write at a 104 to 105 combined ratio and still cover its cost of capital, which lowers the level at which underwriting discipline becomes financially necessary at exactly the point competition is testing it.
