UnitedHealth Group and Allianz SE Remain Atop AM Best’s Largest Insurer Rankings

OLDWICK, N.J.--(BUSINESS WIRE)--UnitedHealth Group Incorporated held onto the top spot in AM Best’s ranking of the world’s 25 largest insurance companies for an eighth straight year, growing net premiums written (NPW) by 12% in 2021 to $226.2 billion. In addition, Allianz SE remained in its top spot by nonbanking assets, at $1.2 trillion, while Berkshire Hathaway Inc. rose to second place from fifth.

AM Best released the rankings of the world’s largest global insurance companies, by NPW and nonbanking assets, in the Jan. 6, 2023, issue of Best's News. The two rankings are based on BestLink data and additional research.

Overall, the two rankings saw some reshuffling in the top spots, with U.S.-based health insurers further strengthening their leading positions. Centene Corp. and Elevance Health Inc. (formerly Anthem Inc.) advanced two places in the NPW ranking to come in at second and third. These gains came at the expense of two Chinese insurers — China Life Insurance (Group) Co. Ltd. and Ping An Insurance (Group) Co. of China Ltd. Both Chinese insurers remained in the top five but China Life fell one slot to No. 4 and Ping An fell to No. 5 from No. 2.

Japan-based insurers National Mutual Insurance Federation of Agricultural Cooperatives, Japan Post Insurance, Dai-Ichi Life and Nippon Life all slipped in the ranking by nonbanking assets, with yen depreciation cited as a major driver. Nippon Life also fell the furthest on the NPW ranking, to No. 25 from No. 18.
