Global insured losses from natural catastrophes during the first half of 2026 totaled an estimated $46 billion, a notable decrease from the $84 billion recorded in the previous year. This figure also stands 28% below the decade-long average of $64 billion, according to the latest Natural Catastrophe and Climate Report from reinsurance broker Gallagher Re. This period marks the lowest first-half insured loss total observed since 2018, indicating a relatively subdued period for the global insurance sector.
The report also points out that the first half of 2026 was the fifth consecutive quarter without any single insured catastrophe event exceeding $10 billion in losses. Economic losses also saw a decline, reaching $142 billion, which is 10% below the 10-year average. Only 11 events in H1 2026 generated insured losses greater than $1 billion, compared to the 10-year average of 16 such events. Severe convective storms accounted for approximately $26 billion of the insured losses, continuing to be the most expensive peril in North America.
Global Catastrophe Trends and Evolving Risks
Gallagher Re's analysis reveals a substantial reduction in insured catastrophe losses during the first half of 2026, with the total dropping to $46 billion. This marks a significant decrease compared to the previous year's $84 billion and is considerably lower than the ten-year average of $64 billion. The period also stands out as having the fewest first-half insured losses since 2018. This decline is attributed to a relatively calm period in terms of major catastrophic events, with only 11 events surpassing the $1 billion insured loss threshold, which is below the average of 16 such events over the past decade. The reinsurance broker highlights that the global insurance market experienced five consecutive quarters without a single insured loss event exceeding $10 billion, signaling a period of reduced financial impact from natural disasters.
Despite the lower overall losses, the report emphasizes the ongoing transformation of global risk landscapes. Noteworthy are the unprecedented early summer heat in Europe and the advent of El Niño conditions in June. Experts predict a 97.4% chance that 2026 will rank among the five warmest years on record, driven by prolonged heatwaves and record temperatures across several European countries. While El Niño is typically linked to decreased Atlantic hurricane activity, Gallagher Re cautions that this phenomenon merely redistributes risk rather than eliminating it. Historical data shows that severe and destructive storms are still possible during El Niño years. The report further points to persistent extreme weather patterns globally, including intense heat in Europe, the devastating earthquake sequence in Venezuela, drought conditions in parts of North and South America, significant flooding in China and Canada, and ongoing severe convective storm activity in the United States, underscoring the complex and evolving nature of climate-related risks.
The Broader Implications of Climate Patterns on Risk Management
Steve Bowen, Chief Science Officer at Gallagher Re, stresses that while the headline loss figures grab attention, the more profound impact comes from observable weather signals and long-term climate pattern shifts. He notes that these changes are increasingly affecting the world, bringing greater humanitarian risk and impact. The potential for a powerful El Niño phase, combined with persistent atmospheric and oceanic warming, will profoundly influence how risks manifest across different regions. This dynamic environment necessitates a more nuanced approach to risk assessment and management, moving beyond historical averages to anticipate future vulnerabilities. The interconnectedness of climate phenomena means that even seemingly localized events can have widespread consequences, requiring a global perspective on risk mitigation and resilience planning.
Bowen further elaborated on the implications of these evolving climate patterns, specifically mentioning the record-breaking heat in Europe during May and June. He highlighted that such extreme weather events can pose significant humanitarian risks and impacts, even without causing extensive physical damage that typically triggers large insurance claims. Nevertheless, the insurance industry's property sector is increasingly recognizing how heat-related claims can lead to physical damage, such as the degradation of structural foundations, and generate additional stress through commercial business interruptions. The arrival of El Niño, while potentially reducing Atlantic hurricane frequency in 2026, does not eliminate the possibility of landfalls. Instead, it underscores the importance of looking beyond seasonal storm counts and focusing on how risk profiles might shift geographically. For insurers, reinsurers, businesses, and governments, building resilience depends not only on understanding existing risks but also on anticipating and adapting to the continuous evolution of these risk landscapes, ensuring robust strategies are in place to cope with future climate challenges.
