The reviews additionally agree that extreme thunderstorms throughout the American Midwest and South continued to trigger billions in extra harm all through spring, reinforcing how weather-related disasters have gotten each extra frequent and extra pricey as communities broaden into high-risk areas.
Swiss Re and Munich Re each establish the identical underlying drivers making these disasters so costly: Extra individuals are constructing properties and companies in harmful areas like wildfire-prone zones and twister alleys, whereas local weather change is making excessive climate occasions extra intense and unpredictable.
The reviews agree that this mixture of elevated growth in dangerous places and worsening climate situations implies that what occurred within the first half of 2025 is probably going only a preview of even costlier disasters to come back, except communities take severe steps to construct extra resilient infrastructure and keep away from development in probably the most hazardous areas.
Cat losses and substitute prices
Swiss Re emphasised the rising wildfire risk, declaring that, earlier than 2015, wildfires on common contributed round 1 p.c of the full insured losses from all pure catastrophes worldwide.
