Home insurance costs spike 47% nationwide since 2020
New analysis reveals that home insurance rates jumped nearly 47% nationwide from 2020 through 2025, driven by escalating climate risks and construction costs. This significant increase places substantial financial pressure on homeowners, particularly in states most exposed to wildfire and flood hazards. The data underscores the widening gap between insurer risk models and household affordability.
Last-resort surplus lines insurance booms as insurers retreat
As traditional insurers withdraw from areas vulnerable to extreme weather, demand for surplus line plans—often used as a last resort—is booming. The Washington Post reports that Americans struggling to find standard coverage are increasingly turning to these non-admitted carriers, which are not subject to the same state rate regulations. This shift exposes households to higher costs and less regulatory protection when paying for coverage in high-risk zones.
Stop-loss premiums for employers rise over 5% in 2026
Medical stop-loss premiums for self-insured employers increased by more than 5% in 2026, according to the Aegis Risk Medical Stop-Loss Premium Survey. On a $100,000 deductible, rates rose from 13.6% to 15.9%, reflecting rising healthcare utilization and costs. These increases ultimately trickle down to employee payroll deductions and reduced benefits as companies seek to offset the higher cost of insuring against catastrophic health claims.
