Severe Convective Storms: Reshaping Insurance & Widening Protection Gaps – Aon Report

Severe Convective Storms: Reshaping Insurance & Widening Protection Gaps – Aon Report

February 3, 2026 discoverhiddenusacom Business

The insurance landscape is undergoing a significant shift as severe convective storms (SCS) – including events like damaging thunderstorms and hailstorms – have overtaken tropical cyclones as the most costly insured peril of the 21st century. This change, detailed in Aon’s 2026 Climate and Catastrophe Insight report, is driven by an increase in both the frequency and severity of these outbreaks, particularly within the United States.

A Changing Risk Profile

This isn’t simply a matter of isolated incidents. The report highlights a fundamental reorganization of natural hazard patterns. In 2025 alone, SCS generated $61 billion in insured losses globally from 61 separate events, marking the third-highest total on record. Economically, SCS were even more impactful, causing $82 billion in losses from 82 events.

Did You Know? Since 2020, 306 severe convective storm events have resulted in economic losses exceeding $1 billion, surpassing the 282 such events caused by tropical cyclones over the same period.

The acceleration of billion-dollar catastrophes is also notable. In 2025, 49 events caused at least $1 billion in economic losses, exceeding the long-term average of 46. Insured losses from these events reached 30, significantly higher than the historical average of 17. The United States bore the brunt of this volatility, accounting for over 54% of global economic losses and 81% of global insured losses, totaling $103 billion.

Wildfires Add to the Toll

California’s Palisades and Eaton fires were the most expensive events of the year, resulting in $58 billion in economic damages and $41 billion in insured losses – the highest wildfire costs ever recorded globally. Despite overall global economic losses from catastrophes totaling $260 billion in 2025 – the lowest since 2015 – insured payouts remained high at $127 billion, marking the sixth consecutive year exceeding $100 billion.

Addressing Protection Gaps

While the protection gap – the difference between economic and insured losses – improved to 51%, the lowest on record, this improvement is unevenly distributed. The report indicates that What we have is largely due to high-impact events occurring in developed markets like the U.S. Emerging markets continue to experience substantial uninsured exposure, with more than half of economic losses remaining uncovered in many regions.

Expert Insight: The improvement in the protection gap, while positive, highlights a growing disparity in risk coverage. Concentrated losses in wealthier nations mask the continued vulnerability of emerging markets, suggesting a need for more equitable risk management solutions.

Parametric insurance, which provides automatic payouts when pre-defined conditions are met, is emerging as a key tool to bridge this gap. Jamaica, for example, secured over $650 million in liquidity within two months of Hurricane Melissa through catastrophe bond protection with parametric triggers, facilitating a faster recovery than traditional insurance methods would have allowed.

Building a More Resilient Future

The Aon report emphasizes the need for increased resilience through “smarter technology and stronger infrastructure; better forecasting, resilient building standards and modernized infrastructure to reduce long-term damage.” Michal Lorinc, head of Aon’s catastrophe insight and author of the report, stated that “Resilience today must be both physical and financial.” Organizations are encouraged to integrate adaptation strategies into their workforce and location planning, invest in predictive analytics and foster cross-functional approaches to weather risk.

Frequently Asked Questions

What type of event is now the costliest insured peril?

Severe convective storms (SCS) have surpassed tropical cyclones to become the costliest insured peril of the 21st century, according to the report.

How did the U.S. Factor into global catastrophe losses in 2025?

The U.S. Accounted for more than 54% of global economic losses and 81% of global insured losses in 2025, reaching a total of $103 billion.

What is parametric insurance and how is it being used?

Parametric insurance automatically releases funds when specified trigger conditions are met. Jamaica used catastrophe bond protection with parametric triggers to secure over $650 million in liquidity following Hurricane Melissa.

As climate events continue to impact communities and businesses, how might innovative risk management strategies and increased investment in resilience infrastructure shape the future of insurance and disaster recovery?
