Natural Disasters in 2025: Significant Adjustments in Insurance Practices

In 2025, natural disasters across the U.S. and Canada resulted in insured losses surpassing $90 billion, according to Swiss Re's Sigma report. These losses were predominantly driven by secondary hazards, including severe convective storms causing $46 billion and wildfires contributing $40 billion. Together, these accounted for 96% of total insured losses. Although total losses were lower than in previous years, the insured share of losses from secondary perils reached a significant 71%. Monica Ningen, CEO of U.S. property and casualty reinsurance at Swiss Re, noted a notable shift in the risk landscape in 2025. The growing impact of secondary perils such as wildfires and convective storms now heavily influences total losses, challenging their traditional "secondary" classification. Significant events like the Palisades and Eaton wildfires in Los Angeles marked unprecedented wildfire losses in Swiss Re's Sigma database. These losses were exacerbated by wildfires impacting high-value areas at wildland-urban interfaces, where urban settings meet natural landscapes. Ningen explained that this trend stems from increased exposure and evolving risk factors. More assets are situated in high-risk areas, and changing weather patterns lead to more frequent, severe events. This results in a persistently higher baseline of losses, necessitating a recognition of these events as part of an ongoing reality. The report underscores the importance of adaptation and mitigation strategies to control escalating losses. Homes built under the Insurance Institute for Business & Home Safety's Fortified program showed significant reductions in claim frequency and severity. Ningen emphasized the need for insurers to manage risk effectively, advocating for comprehensive understanding of exposures and support for mitigation efforts. Strategies like enforcing stringent building codes and informed land use can significantly reduce future loss costs. Furthermore, the global insurance landscape is experiencing notable shifts, with insurtech funding maintaining momentum and financial services increasingly adopting digital customer interactions. This emphasizes the evolving nature of the industry in response to changing dynamics and technological advancements.
