Record Underwriting Profits in U.S. Property and Casualty Insurance Industry

The U.S. property and casualty insurance industry achieved its most favorable financial outcome in a decade in 2025, according to a recent AM Best report. The sector marked $84 billion in total underwriting profits over two years, reversing $51 billion in losses from 2021 through 2023.

This positive trend began in 2024 with a $45 billion net underwriting gain that extended into 2025. Despite losses from the Los Angeles wildfires in early 2025, the sector's performance remained robust. Insights into these findings are detailed in AM Best's report titled "2025 P/C Snapshot: Strongest Performance in a Decade Showcases Resilience."

Personal and Commercial Lines Drive Recovery

Personal lines led the recovery, with underwriting profits nearly quadrupling to over $45 billion in 2025. Commercial lines profits also more than doubled, exceeding $19 billion. The private passenger auto sector showed significant improvement, with its combined ratio dropping below 100 in both 2024 and 2025, a positive shift after three years of higher ratios.

David Blades, associate director at AM Best, emphasized that insurers in personal auto and homeowners lines benefitted from advancements in technology and data analytics. These enhancements improved underwriting, claims processing, and pricing strategies. The sustained momentum in pricing initiates in 2024, leading to enhanced net earned premiums across both years.

Commercial Lines and Emerging Concerns

Throughout the five-year report period, commercial lines maintained steady underwriting profitability due to pricing sufficiency, better investment returns, and adequate reserves. However, AM Best notes disparities within the sector. Casualty lines, particularly commercial auto liability and other liability lines, continue to face pressures from adverse developments and increased claims severity.

Christopher Graham, senior industry analyst at AM Best, highlighted the variability in calendar-year underwriting performance across major commercial lines, despite the overall positive results. In 2025, commercial auto liability encountered an additional $2 billion in reserve deficiencies, mainly due to the 2023 and 2024 accident years.

Regulatory Developments and Future Outlook

Significant regulatory actions emerged as North Carolina became the first U.S. state to ban third-party litigation funding entirely. This decision is being closely watched by casualty underwriters and brokers as it could set a precedent for other states. Despite favorable headline figures, brokers and underwriters continue to experience cost pressures in casualty insurance as they navigate challenging pricing and coverage conditions, particularly in commercial auto and general liability.
