Non-peak (“secondary”) perils and record-setting weather and climate events drove global insured losses from natural catastrophes to an estimated $123 billion in 2023, the fourth consecutive year to exceed $100 billion, according to the annual Natural Catastrophe and Climate Report by global reinsurance broker Gallagher Re. Of the total estimated insured losses, private insurers covered $110 billion and public insurance entities, $13 billion.
The global economic cost of all natural perils was estimated at $357 billion – the eighth consecutive year global losses have surpassed $300 billion.
When looking solely at climate and weather events, which excludes losses from earthquakes and other non-atmospheric-driven events, insured losses were estimated at $116 billion. The economic costs reached an estimated $301 billion.
Gallagher Re’s Natural Catastrophe and Climate Report summarizes the global and regional insured and economic losses due to natural catastrophes in 2023; breaks down loss drivers and trends; and provides insight on such topics as insurability, the role of climate change in reinsurance and regulatory demands.
Gallagher Re’s Chief Science Officer Steve Bowen said: “We continue to witness an increase in the severity and high-impact frequency of natural catastrophe events. These effects bring multifaceted and complex challenges to the (re)insurance industry, as the importance of blending today's view of risk with the anticipated downstream implications of tomorrow grows more critical.”
Severe Convective Storms
The severe convective storm (SCS) peril was the dominant driver of losses in 2023, making up an estimated 58% of global insured losses. This translates to a record-setting $71 billion, of which the US accounted for $60 billion. In fact, six of the top 10 costliest insured events of 2023 were SCS events in the US.
Bowen said: “‘Peak’ perils are still anticipated to drive the highest individual event losses. However, the continued growth of damage from ‘non-peak/secondary’ perils, such as SCS, is changing the way we view and plan for natural catastrophe risk. It also increases the importance of analytics and catastrophe modeling to properly gauge how a combination of climate change-influenced event behavior and socioeconomic parameters are leading to higher loss potentials.”
Protection Gap
The February earthquake sequence that affected Turkey and Syria was the most expensive event on an economic basis, with losses estimated at $46.2 billion; insurance only covered $6.1 billion. This natural catastrophe was a significant contributor to the 66% worldwide protection gap – the portion of economic costs from events not covered by insurance. Other events that drove the year’s protection gap included the Marrakech-Safi earthquake in Morocco, Typhoon Doksuri which led to major flooding in China, and Hurricane Otis in Mexico.
“While we continue to witness an expansion of insurance protection into vulnerable parts of the world, there remain considerable gaps in coverage that leave many developing countries highly exposed to catastrophe risk,” Bowen said. “The need for more guaranteed climate or natural catastrophe financing to mitigate or adapt to a more complex world of natural hazards becomes more critical by the day. The growth of private and public sector partnerships bringing new insurance options to underserved communities is a promising trend that needs to further accelerate.”
