The numbers from Swiss Re are hard to dismiss. The world's second-largest reinsurer has confirmed what many in the industry quietly feared: climate-driven disasters are no longer outlier events. They are the baseline.
What Swiss Re's Latest Data Actually Shows
Natural catastrophes in 2025 caused USD 107 billion in insured losses across 190 events, with nearly half of total economic losses covered by insurance, highlighting both insurance's critical role and the persistence of a substantial protection gap.
Swiss Re estimates that insured losses from natural disasters could reach approximately USD 148 billion in 2026, reflecting a return to long-term trends. In a severe loss scenario, claims could climb as high as USD 320 billion, underscoring the growing volatility facing the global insurance industry.
Who Is Swiss Re and Why Does Its Warning Matter
Swiss Re is one of the world's largest reinsurers, meaning it provides insurance to insurance companies. When Swiss Re signals structural risk, the entire industry listens. Its annual sigma reports are among the most cited sources in catastrophe risk analysis globally.
Over the past decade, insured losses from natural catastrophes have trended sharply upward. Swiss Re confirmed that global insured catastrophe losses exceeded USD 100 billion annually for six consecutive years, a historically unprecedented run.
What Events Drove the 2025 Losses
The year 2025 was defined not by one catastrophic hurricane but by the relentless accumulation of smaller, faster-moving disasters.
The January wildfires in Los Angeles were the defining events of the year. They caused USD 40 billion in insured losses, a record for the wildfire peril globally. Strong Santa Ana winds, drought conditions, dense urban development, and ample fuel drove destruction across one of the highest-value wildland-urban interfaces in the United States.
For the third consecutive year, severe convective storms generated more than USD 50 billion in insured losses globally. Urban expansion in hail-prone regions and reconstruction costs still 37 percent above pre-COVID levels contributed to elevated losses.
Who Bears the Biggest Financial Burden
The insurance protection gap, meaning the difference between total economic losses and insured losses, remains one of the most consequential fault lines in global risk finance.
Swiss Re estimated total global economic losses at USD 220 billion in 2025, of which only 49 percent were insured. In many developing economies, between 80 and 90 percent of catastrophe-related losses remain uninsured, exposing households, businesses, and governments to severe financial strain when disasters strike.
Balz Grollimund, head of catastrophe perils at Swiss Re, warned that the relatively lower losses recorded in 2025 should not be mistaken for a reduction in underlying risk.
What Is Driving the Long-Term Rise in Claims
Swiss Re's analysis shows that exposure growth, driven by population growth, urban expansion, and rising asset values in risk-prone areas, accounts for more than 80 percent of the long-term increase in weather-related insured losses globally since 1970. In North America, insured losses from wildfires are growing at an annual rate of around 14 percent, partly attributed to longer fire seasons and shifting temperature and precipitation patterns.
Global insurance losses from natural catastrophes continue to follow a 5 to 7 percent annual real-terms growth rate that has been the norm in recent years.
Who in the Industry Is Most Exposed
Many insurers have raised premiums and tightened coverage terms in disaster-prone markets. However, actuarial experts caution that simply charging higher premiums may not be a sustainable solution if losses continue to outpace predictions. In California, several major insurers have already stopped offering home insurance in wildfire-prone areas, and state regulators were forced to intervene with new rules to maintain coverage in high-risk zones.
