Chubb LtdChubb CEO warns of ongoing war risk in Strait of Hormuz, boosting demand for marine war risk insurance, which Chubb underwrites.

Chubb Chairman and CEO Evan Greenberg described the Strait of Hormuz as a 'war-zone environment' where conditions change 'from day to day, hour to hour,' highlighting ongoing risks to global oil shipments. Chubb, the world's largest publicly traded property and casualty insurer and a major underwriter of commercial shipping, jointly launched a $400 million marine war risk insurance consortium with Lloyd's of London on June 19, 2026, and is participating in a U.S. International Development Finance Corp.-backed $20 billion reinsurance program. Greenberg noted that only a narrow channel is being used for transit, limiting vessel traffic, while the U.S. Navy works to open broader corridors. The company reported a P&C combined ratio of 84.0% and P&C underwriting income of $1.79 billion in Q1 fiscal 2026, up 306% year over year, with net premiums written reaching $14.0 billion. Chubb shares closed at $323.40 on June 18, trading at roughly 11.4 times forward earnings.
