2025 Reinsurers ranking. — Madrid : Fundación MAPFRE, 202652 p.Traducido bajo el título: Ranking de reaseguradores 2025. - Madrid : Fundación Mapfre, 2026Sumario: This second edition of the Reinsurers Ranking analyzes the performance of the world's largest reinsurance groups in 2025, ranked according to the volume of gross premiums accepted as reported in their annual financial statements. The report's comparison covers both the overall market and, specifically, the Life and Non-Life segments. Overall, the sector's performance in 2025 continued to be supported by firm conditions in catastrophe coverage and by the expansion of the Life segment. It also highlights that the trend toward lower concentration in the sector continues. Consequently, the combined market share has been declining, reflecting an increasingly diversified reinsurance sector, albeit one that is more geographically concentrated. — Ámbito geográfico: Internacional1.
