2025 U.S. P&C Insurance Sector Performance Insights
The preliminary results for the U.S. property and casualty (P&C) insurance sector in 2025 showcase a robust underwriting performance, attributed to reduced catastrophe activity, as reported by Verisk and the American Property Casualty Insurance Association (APCIA). Private P&C insurers in the U.S. achieved an estimated net underwriting gain of approximately $63 billion, a substantial increase from the $23 billion gain in 2024, following a $22 billion loss in 2023. The industry's combined ratio improved to 92.9% from 96.6% in the previous year, and policyholders' surplus grew from $1.1 trillion to $1.2 trillion. Net written premiums rose by 4.8% to $971 billion, while net earned premiums increased by 6.3% to $953 billion.
Despite improved underwriting metrics, the industry's net income after tax fell to $148 billion from $169 billion in 2024, primarily due to weaker investment outcomes. Realized capital gains decreased to $23 billion from $79 billion the previous year. Verisk highlighted that aside from exceptional gains by one specific insurer, overall investment returns were in line with historical norms, even though they surpassed those in 2022 and 2023.
Saurabh Khemka, president of Verisk Underwriting Solutions, emphasized that the 2025 results were largely driven by favorable catastrophe conditions rather than fundamental risk shifts. He noted a significant reduction in hurricane-related claims, which contributed to decreased catastrophe losses due to fewer U.S. landfall events. Khemka pointed out improvements in certain lines, such as personal auto, resulting from strategic rate actions and more rigorous underwriting, with workers’ compensation maintaining favorable results.
Stabilization and Market Challenges
APCIA's Robert Gordon observed stabilization within the industry for 2025, with incurred losses remaining flat due to low hurricane impact. He noted a slowdown in net written premium growth from 8.8% in 2024 to 4.8% in 2025. Gordon further mentioned decreased insurance spending within personal and commercial segments relative to broader economic measures, with net income declining by 12.6% partly due to reduced realized capital gains.
The outcomes highlight pressures such as rising costs from severe localized weather events causing disputes and increasing claims outside major declared catastrophes. This trend affects commercial auto, marine, and SME property portfolios, prompting companies to reassess their aggregation, retention strategies, and pricing models. Insurers are increasingly using analytics and automation to refine underwriting and claims processes, leveraging AI and external data to enhance risk assessments broadly across P&C portfolios.
Financially, the industry’s strong sub-93 combined ratio and growing surplus improve balance sheets in preparation for potential volatility. However, with declining realized capital gains and uncertain interest rate trends, insurers may need to adjust reliance on investment income to buffer underwriting margin changes. Verisk and APCIA describe 2025 as a stabilizing year, not indicative of a new trend, underscoring the need for sustained underwriting discipline and precise risk management as the sector advances into 2026 and beyond.
