That is a man whose company has skin in the game every time a vessel transits the Strait of Hormuz.Chubb (CB) Chairman and CEO Evan Greenberg made those remarks Sunday, June 21, on Fox News’ Sunday Morning Futures, offering one of the most candid assessments of the Hormuz situation I have seen from a corporate executive. His vantage point is uniquely credible.Chubb is a major insurer of commercial shipping globally, which means the company's underwriters are pricing this risk every single day.Mines are the greatest uncertainty.Greenberg continued.

For companies that depend on Hormuz, the channel constraint is a genuine operational problem, not merely a headline risk.How does this directly affect Chubb's business?This is where the story gets concrete for CB shareholders.
