How wildfires and storms drove insurance losses in 2025

Brief
Extreme weather events around the world, such as wildfires
and storms, were the major driver behind $107bn in insured losses in 2025,
according to industry data.
The Los
Angeles wildfires alone caused record-high $40bn in insured losses
from fires, says a new report from
reinsurance company Swiss Re.
The report notes that, while overall insured losses in 2025
were lower than previous years, this was due to a “[luck] rather than a
reduction in risk”, partly due to no major
hurricanes hitting the US.
Insured losses refer to damages that are compensated for by
insurance companies.
Despite lower losses in 2025 than the trend over recent
years, they are still rising by an average of 5-7% each year since 1996,
accounting for inflation, says Swiss Re.
The report itself does not explicitly discuss the role of
human-caused climate change in the events driving these losses.
But the extensive ways in which climate change exacerbates
and drives extreme weather are well established in scientific
literature.
Other reports and media coverage also show how some parts of the world hit by frequent and intense extreme weather now face the possibility of becoming “uninsurable” due to unaffordable premiums or insurers pulling out of the market.
