Evan Greenberg

Evan Greenberg chairs and leads Chubb Limited, the Swiss-domiciled insurer that is the world's largest publicly traded property and casualty firm by assets. In June 2026 Chubb led the formation of a Lloyd's-backed war-risk consortium providing $400 million in capacity for commercial vessels transiting the Strait of Hormuz. On 22 June Greenberg described the security situation in the strait as being assessed "hour to hour", identifying mines as "the greatest uncertainty" for underwriters and warning that premium rates would remain elevated for as long as SAFE passage could not be guaranteed.

Greenberg has run Chubb since 2004, first as CEO of the predecessor ACE Limited before engineering its $28.3 billion acquisition of the legacy Chubb Corporation in 2016, one of the largest mergers in the history of the insurance industry. Under his tenure the group expanded into commercial, personal, and life and health lines across more than 50 countries. He is the son of Maurice "Hank" Greenberg, who built AIG into a global insurance giant, and worked at AIG before founding ACE's growth era. Greenberg is widely regarded as one of the most influential underwriting voices in global specialty risk markets.

His public comments on the Hormuz war-risk consortium carry unusual market weight: Chubb's willingness to anchor the facility determined whether Lloyd's syndicates would co-participate. The consortium's existence signals that institutional capital will price Hormuz transits rather than exclude them, which is critical to maintaining any commercial shipping in the strait during the conflict. How Chubb prices and manages this exposure will set the benchmark for the broader specialty war-risk market through the Iran conflict.
