Chubb

Chubb is one of the world's largest publicly traded property and casualty insurers, listed on the New York Stock Exchange and headquartered in Zurich, with operations across 54 countries. Its core business spans commercial and high net worth personal lines alongside marine and aviation underwriting.

In June 2026 Chubb extended that marine Arm into high-risk political and conflict cover, anchoring a Lloyd's of London consortium that opened $400m of Hormuz war-risk capacity on 19 June, split between hull, Protection and Indemnity, and cargo cover, with every covered cargo required to clear sanctions screening under existing OFAC restrictions.

The consortium marked the first return of private war-risk capacity to the strait since the International Group of P&I Clubs withdrew cover, work usually dominated by specialist Lloyd's syndicates and P&I clubs rather than a diversified insurer of Chubb's size. Because the screening condition ties Chubb's exposure to the diplomatic status of the Iran nuclear talks, the facility stands as a running gauge of private-sector confidence in any eventual reopening.
