Global reinsurance capital up 7% to $607bn in 2024: Guy Carpenter, AM Best

Published on December 31, 2024

Data from Guy Carpenter, the reinsurance broking arm of Marsh McLennan, and ratings agency AM Best, shows that global reinsurer capital has grown by approximately 7% year-on-year, rising from $568 billion in 2023 to a projected $607 billion in 2024, with growth in both traditional and alternative capital.

Traditional capital grew by 7%, rising from $468 billion at year-end 2023 to an estimated $500 billion at the end of 2024, according to Guy Carpenter and AM Best.

Similarly, alternative reinsurance capital increased by 7% year-on year, from $100 billion to $107 billion. This growth is attributed to robust activity in the 144A catastrophe bond market, which saw 67 cat bonds issued, placing approximately $17 billion in limit for 2024, according to Guy Carpenter’s figures.

As shown in the chart below, global reinsurer capital is at its highest level to date, having increased by $171 billion, or 39%, since 2018. The 2024 total is also $36 billion higher than the previous end-of-year peak recorded in 2021.
