Global Reinsurance Reaches Record Numbers in 2024: Gallagher Re

Global reinsurance capital reached a record $769 billion in 2024 with strong returns on equity well above the cost of capital, positioning the industry for continued growth in 2025 despite potential headwinds, according to Gallagher Re’s full-year 2024 Reinsurance Market Report.
The annual report tracks the capital and profitability of the global reinsurance industry, analyzing 45 global reinsurers in the Gallagher Reinsurance Index, as well additional detail from 16 “subset” companies that disclose more complete information, including natural catastrophe losses and prior-year reserve releases.
The reinsurance sector demonstrated considerable financial strength in 2024, with dedicated capital increasing 5.4% year-over-year. Companies in the Gallagher Re Index, which contribute more than 80% of the industry’s capital, saw a 5.3% rise in capital to $629 billion. This growth was primarily driven by net income of $117 billion, and partially offset by $58 billion in capital returns.
Revenue growth for the subset companies was 8.1%, supported by higher rates in property and casualty reinsurance, though exposure growth was muted as companies sought to reduce their exposure to U.S. casualty business, Gallagher Re noted.
The reported combined ratio of the subset companies decreased to 86.8% from 87.3% in 2023. The underlying combined ratio for the same 16 reinsurers, which excludes the impact of catastrophes and prior year reserve developments, continued its downward trend, was 93.0% in 2024 compared to 96.0% in 2023—the strongest level since Gallagher Re began publishing its Reinsurance Market Report in 2014.
Shifting Catastrophe Risk Landscape
A notable trend emerging from the report is the changing relationship between reinsurers and catastrophe losses, Gallagher Re found.
While global insured natural catastrophe losses increased to $154 billion in 2024 from $123 billion in 2023, reinsurers’ share of these losses has been declining. The subset companies in the Gallagher Re Index carried just 6.9% of these losses in 2024, down from 7.3% in 2023 and 9.2% in 2022.
This reduction reflects strategic adjustments in reinsurance coverage, including higher attachment points and the changing nature of catastrophe events. The share of natural catastrophe losses on reinsurers was 7.6% in 2024, below the normalized natural catastrophe loss expectation of 9.0%, Gallagher Re found.
These shifts indicate that primary insurers are retaining more catastrophe risk, while reinsurers have effectively repositioned their portfolios to provide more remote protection.
Despite these portfolio adjustments, the reinsurance industry’s capacity to absorb significant catastrophe events remains substantial, providing stability in an increasingly volatile climate environment, Gallagher Re noted.
Outlook for 2025: Strength Amid Challenges
The reinsurance industry is well-positioned to deliver another robust performance in 2025, with the subset companies on track to earn an underlying ROE of approximately 15%, assuming normal natural catastrophe losses and stable investment markets, the broker reported.
While year-to-date renewals present some headwinds for reinsurance buyers, these are expected to be offset by continued benefits from higher reinvestment yields, though these benefits will be more modest than in previous years, according to the report.
The year has started with significant challenges, as the Southern California/Los Angeles wildfires are estimated to cause $35 billion to $40 billion in insured losses. Major reinsurers have indicated these events may consume 25% to 33% of their annual catastrophe budgets.
Looking forward, traditional reinsurance capital is projected to increase by approximately 6% in 2025, driven by continued strong profitability despite expectations of higher capital returns to shareholders.
