TOP 20 Global Re/Insurance Brokers

According to  A.M. Best data and research, Marsh McLennan retains the No. 1 spot in Best’s Review’s Top Global Insurance Brokers ranking with $19.8 bn in total revenues, $7.6 bn ahead of second-place AON. The expected Aon/WTW combination deal that would have substantially affected this year’s brokers ranking was scuttled last July after regulatory involvement.

In the ranking, the TOP 5 remained the same as last year. However, there was a shuffle in the bottom half of the top 10. Acrisure LLC moved from No. 9 to No. 7; Alliant Insurance Services Inc. jumped from 11th place to the eighth spot; Truist Insurance Holdings Inc. dropped to No. 9 from No. 7; and Lockton Inc. moved from No. 8 to No. 10.
