Severe Convective Storms Drive $51B in U.S. Insured Losses for Third Straight Year
Event summary
- $51 billion in U.S. insured losses from severe convective storms in 2025, marking the third consecutive year exceeding $50 billion.
- Total economic damages reached over $68 billion, ranking 2025 as the third costliest year on record for this peril.
- Non-weather factors—demographic shifts, legal system abuse, and rising construction costs—account for up to 90% of loss growth since 2000.
- Record 300 tornadoes in March 2025 generated $8.4 billion in insured losses; an EF5 tornado struck North Dakota in June.

The big picture
Severe convective storms have transitioned from a regional, seasonal concern to a year-round, record-setting insured loss challenge. The Insurance Information Institute's report highlights that non-weather factors—such as demographic shifts and legal system abuse—are the dominant drivers of rising losses, necessitating coordinated action on multiple fronts to keep insurance accessible for at-risk communities.
