2025 U.S. P/C Insurance Sector Resilience: Trends & Challenges
In 2025, the U.S. property and casualty (P/C) insurance sector demonstrated significant resilience, achieving its lowest Net Combined Ratio (NCR) in over ten years. This success came despite challenges such as the January 2025 Los Angeles wildfires and ongoing geopolitical uncertainties. These insights are part of the "P/C Economics and Underwriting Projections: A Forward View" report, a collaboration between the Insurance Information Institute (Triple-I) and Milliman.
Economic and Geopolitical Challenges
Michel Leonard, Ph.D., CBE, chief economist and data scientist at Triple-I, observed that while the broader U.S. economy remained stable amid stronger-than-expected GDP growth in the third quarter, potential vulnerabilities were noted. Leonard indicated that increased economic, political, and geopolitical uncertainties could impact the industry, particularly with the potential rise in P/C replacement costs in 2026. He warned that a rise in unemployment could lead to economic contraction.
Key Industry Metrics
Data collection challenges surfaced due to a U.S. government shutdown in Q4 2025, impacting economic data availability and showing a slowdown in underlying P/C growth, notably in premium volume. For 2025, P/C Aggregate Net Premium Growth is estimated at 5.9%, marking a reduction from 2024. The Homeowners insurance Net Combined Ratio for 2025 is projected at 99.6 points, mirroring 2024 levels despite significant wildfire losses.
Personal Auto is expected to improve, with a 2025 Net Combined Ratio of 94.4 points, though its premium growth rate has decelerated to 3.6%, the lowest since 2020. General Liability and Commercial Auto lines are forecasted to remain above a Net Combined Ratio of 100 points, but improvements are predicted for 2026 and 2027. Workers' Compensation is maintaining strong results with Net Combined Ratios predicted to range from the high 80s to low 90s through 2027.
Insights from Industry Leaders
Patrick Schmid, Ph.D., chief insurance officer at Triple-I, noted the achievement of the lowest Net Combined Ratio in a decade, aided by an uneventful hurricane season and robust homeowners performance. Schmid pointed to solid premium growth in personal lines and a narrowing performance gap between personal and commercial lines.
Jason B. Kurtz, FCAS, MAAA, a principal and consulting actuary at Milliman, remarked that the General Liability segment remains challenging, with loss ratios higher than any in the past 25 years. Despite forecasts for improvement in the next two years, profitability concerns persist. There is an expectation that further premium growth may be needed to enhance profitability in this segment.
Donna Glenn, chief actuary at NCCI, projected favorable underwriting results for Workers' Compensation due to stable premium trends and effective risk management. While a few rate increases have been filed in NCCI states, Glenn anticipates continued stability based on current data.
Future Outlook for the P/C Insurance Sector
The report underscores that while 2025 was a year of resilience for the P/C insurance sector, there are looming uncertainties and challenges that the industry must navigate moving forward. These include regulatory compliance requirements and innovative risk management strategies that carriers must adopt to maintain stability and growth.
