Property insurance: Adapting to higher losses
One of the most pronounced trends in the insurance industry has been a steady increase in both the size and number of property insurance claims. A variety of factors contribute to this trend, and its effects can be seen in the form of significant – in some instances dramatic – rate increases over the past several years. Comparable trends also can be seen in both private passenger and commercial auto insurance, commercial general liability, umbrella insurance, and other liability lines of business, but it is the commercial and residential property insurance sectors that have been particularly volatile of late.
Of course, sharp rate increases are the inevitable consequence of steadily increasing insured losses. According to one leading reinsurance brokerage’s analysis, total global insured losses from natural catastrophes reached $118 billion in 2023.1 What’s more, although the losses in 2023 were up sharply, the year was not an anomaly. As another analysis shows, 2023 was the sixth year of the past seven in which insured losses topped the $100 billion mark.2
It is also important to note that major catastrophic losses are not the only factors at work here. Many of the losses in 2023 were driven by high-frequency and lower-dollar “secondary” catastrophe events rather than low-frequency and higher-dollar “primary” events such as major earthquakes or tropical cyclones that reached land.3
Multiple factors contribute to the rising levels of global insured losses. Some of these factors include a rise in exposure values and replacement costs due to continued construction in high-hazard areas and a general inflationary environment that continues to drive up both property values and repair costs. These pressures are exacerbated by growing population densities in areas that are subject to natural hazards – such as coastal communities and regions susceptible to wildfire risk – leading to a higher volume of exposed assets.
Several recent natural disasters demonstrate the compounding impact of these simultaneous trends. Examples include the August 2023 wind-driven wildfires on the island of Maui, which destroyed more than 2,000 structures and caused an estimated $4 billion to $6 billion in damages, 75% of which are likely to be insured.4 Only a few weeks later, a series of wildfires in British Columbia caused an additional $720 million in insured losses.5
Yet, as great as the 2023 losses were, they were overshadowed by the estimated $13 billion in insured losses from the devastating 2018 wildfire season in California.6 Examples such as these illustrate how a combination of inflationary pressures, population shifts, and increased construction in at-risk areas have contributed to rising rates and industry exposure.
Concerns over climate change add further complications, causing many insurers to rethink their risk strategies and pricing to reflect their concern that rising global temperatures create more significant potential for large losses. One change some insurers are implementing is an increased use of forward-looking predictive analytics to price future risk rather than relying solely on traditional risk modeling that depends primarily on historical data to identify near-term risk.7
Moreover, one group’s industry analysts report its modeled losses – that is, the losses insurers should reasonably expect to experience – exceed the actual losses the industry has reported to date. This analysis suggests the industry should be prepared for higher levels of losses in years to come. Using a methodology known as probabilistic catastrophe modeling, Verisk Analytics suggests insurers should expect to experience total insured losses from natural catastrophes well in excess of $100 billion every year, with annual losses greater than $200 billion now deemed “plausible.”8
