The U.S. property and casualty insurance industry posted its lowest net combined ratio in more than a decade in 2025, signaling a stronger underwriting position after years of inflation, supply chain disruption and claims-cost pressure. The improvement was especially visible in personal lines, where personal auto and homeowners both showed stronger results after several difficult years.
For claims adjusters, the recovery does not mean claim handling pressures are easing across the board. Triple-I and Milliman pointed to continued economic uncertainty, elevated catastrophe risk, higher claims severity and persistent inflation as ongoing challenges. Those factors continue to affect estimating, reserving, settlement expectations and the cost of restoring damaged property or resolving injury claims.
Homeowners insurance showed one of the strongest improvements, even with an active catastrophe year that included Los Angeles wildfires in the first quarter. The line benefited from easing replacement cost pressures and prior pricing actions, but replacement costs remain a long-term concern. Triple-I warned that replacement costs are expected to accelerate again through 2028 and eventually outpace overall U.S. inflation. That outlook matters for property adjusters working with repair estimates, contents valuations, contractor pricing and supplemental claims.
Personal auto also improved, with a 2025 net combined ratio of 91.8, but premium growth slowed to its lowest level since 2021. Commercial auto and general liability remain under pressure, with both lines reporting combined ratios above 100. Milliman cited litigation pressure and claims severity trends as key drivers of elevated loss costs, keeping liability and commercial auto adjusters focused on documentation, early evaluation, negotiation strategy and litigation management.
Workers' compensation remains one of the steadier lines, with projected combined ratios in the low 90s through 2028. Even so, the preliminary 2025 combined ratio rose about five points from the prior year, driven by higher loss and underwriting expense ratios. For workers' compensation adjusters, the line's stability does not remove the need to monitor medical costs, return-to-work timelines and expense control.
The report also points to structural shifts in property markets. Triple-I noted that the standard market share in fire and allied lines fell from 66.7 percent in 2016 to 52.7 percent in 2024 as premiums moved toward excess and surplus and residual markets. That trend can affect adjusters through different policy forms, coverage limitations, claim reporting practices and dispute patterns, especially in higher-risk property markets.
