Reinsurers, Not Just Inflation, Doubling Premiums
A new Wharton study argues that global reinsurers are a primary driver behind insurance premiums doubling, separate from standard inflation. By analyzing wildfire and hurricane data, the research suggests reinsurers are fundamentally repricing risk, a critical insight for underwriters facing pressure on their own pricing models.
The cost of reinsurance for U.S. property-catastrophe risk has doubled, a significant factor in the 33% surge in homeowner's insurance premiums from 2020 to 2023. This escalation in reinsurance expense is responsible for nearly two-thirds of the increased premium costs in disaster-prone regions. For households in the top 10% of disaster risk, the reinsurance shock added an average of $375 to their annual premiums by 2023. A "hard market" for reinsurance is characterized by limited coverage availability and high costs, driven by a confluence of factors. These include an increase in the frequency and severity of natural disasters, economic and social inflation, and supply chain disruptions that drive up the cost of claims. Consequently, reinsurers are adjusting their risk models and pricing strategies, leading to stricter underwriting protocols. In response to these pressures, reinsurers are implementing structural changes such as raising attachment points, tightening terms and conditions, and limiting aggregate covers. This means primary insurers have to retain more risk before their reinsurance coverage kicks in. These increased costs are then passed on to policyholders through higher premiums. Some U.S. property catastrophe reinsurance rates saw increases of up to 50% in January 2023 alone. Despite a challenging environment with significant natural catastrophe losses, the global reinsurance industry is in a strong financial position. In 2023, reinsurers achieved their highest profits in years, fueled by high investment yields and consistent rate increases. Global reinsurance capital reached a record $729 billion at the end of 2023, a 12% increase from the previous year, with reported return on equity jumping to 20.2%. Looking ahead, the global reinsurance market is projected to grow at a compound annual rate of 6.5% between 2024 and 2032. However, if current reinsurance costs persist, homeowners in the most climate-exposed areas could face an additional $700 in annual premiums by 2053. This trend is forcing a critical reassessment of risk and affordability in the insurance market.
