How large were global insured and uninsured natural disaster losses?
Core argument: Global insured losses from natural disasters exceeded $127bn in 2025, with more than $100bn occurring in the US after the Los Angeles fires, according to insurance broker Aon.
Global insured losses of more than $127bn from natural disasters were dominated by more than $100bn occurring in the US in 2025 after the Los Angeles fires, according to a new industry report on climate and other extreme events. Overall global economic losses stemming from disasters, including thunderstorms and earthquakes, totalled about $260bn, according to the review by insurance broker Aon. But more than half of those losses remain not covered by insurance, highlighting the persistence of inadequate coverage in emerging markets, it said. “Extreme weather events are becoming more frequent and unpredictable, affecting new geographies and sectors, and challenging long-held assumptions about resilience,” wrote Greg Case, Aon chief executive. “Weather exposures are rising,” he noted. Insured losses from climate disasters were 27% higher than the long-term average since 2000.
