ALIRT Insurance Research, a US insurance research and analytics firm focused on the property and casualty sector, has released a new report highlighting widening differences in the performance of residual property insurance markets across California, Florida, Louisiana, and Texas. The company says that although the wider US property insurance market has returned to profitability, conditions within higher-risk states continue to follow very different paths. In its latest biannual publication, Residual Property Market Trends in Four Higher Risk States, ALIRT points to a significant improvement in underwriting results across US property insurance during 2025.The homeowners insurance segment generated approximately $17 billion in underwriting profit, marking its strongest annual performance in more than ten years. The company argues that developments within residual insurance markets offer a clearer indication of the health of local property insurance sectors and can reveal underlying issues not evident in nationwide results. ALIRT concludes that changes within residual property insurance markets may act as an early indicator of financial strain within the wider private insurance sector.
