Global Insurance Ratings

This Top Global Reinsurance Groups directory is based on research data from rating agency A.M. Best, and ranks companies based on full-year 2025 performance.

Listing the top reinsurers in the world, this directory provides a simple way to analyse the world’s top reinsurance companies.

You can sort the table by any of the headings and search it to analyse individual reinsurance companies.

Companies that report under IFRS 17 are ranked 1 to 16 based on gross reinsurance revenue, and companies that report under non-IFRS 17 are ranked 1 to 34 based on gross written reinsurance premium. All companies that provided non-group reinsurance financial data were considered by AM Best.
