U.S. Property and Casualty Insurance Industry Outlook for 2025

According to a recent report by AM Best, the U.S. property/casualty insurance industry achieved its strongest performance in ten years during 2025. This outcome was driven by favorable pricing and investment returns, effectively countering challenges from claims and liability volatility.

The "Review & Preview Best’s Market Segment Report" underscores ongoing improvements in pricing and investment earnings across primary insurance business lines. AM Best projects that net underwriting income for the industry will exceed $39 billion in 2025, doubling from the previous year. Despite substantial losses from natural disasters such as California wildfires, the report predicts an improvement in the calendar-year combined ratio to 95.0 from 97.1 in 2024. Stabilization in rate and pricing trends, however, may pressure underwriting results in 2026, especially if catastrophic events occur.

Challenges in 2026

Jacqalene Lentz, Senior Director at AM Best, discussed potential challenges, forecasting "lower net premiums written growth in 2026 and tighter margins across the P/C industry." Macroeconomic factors are likely to increase claim costs due to rising prices of materials necessary for repairs, potentially elevating the industry's loss ratios slightly.

In 2025, personal lines are set for further improvement with positive trends in private passenger auto and homeowner segments. While commercial lines like workers' compensation and commercial property demonstrate underwriting profitability, commercial auto, general liability, and medical professional liability face less favorable outcomes. The sector grapples with social inflation and third-party litigation funding, which exacerbate loss severity, particularly impacting commercial auto and general liability.

Anthony Molinaro, Associate Director at AM Best, highlighted expectations of lower net premium growth due to declining rates in several commercial lines. This trend may result in a slightly higher combined ratio in 2026, although profitability should be maintained. Molinaro added that "personal lines’ profit margins are likely to be squeezed in 2026," with the segment expected to yield solid but slightly less favorable underwriting results.
