Lloyd's Closed the Strait of Hormuz Without a Single Warship
Five insurance companies shut down 20% of global seaborne oil. No mines. No blockade. No navy required.

On 4 March, five major P&I clubs cancelled war-risk cover for the Persian Gulf, effective the following day (Insurance Journal, 4 March 2026). Within 24 hours, daily Strait of Hormuz transits collapsed from a 79-vessel average to five crossings — a 94% decline (Windward Maritime Intelligence, 5 March 2026).
The mechanism is elegant and irreversible in the short term. Reinsurers exercised 72-hour exit clauses. Charterers' liability cover evaporated. VLCC spot rates hit an all-time record of $436,000/day (Seatrade Maritime, 3 March 2026). No shipowner sends a $100 million vessel through a war zone when nobody will insure the hull, the cargo, or the crew.
Washington's response was a $20 billion DFC reinsurance facility — announced 6 March, Chubb named lead underwriter on 11 March. The legal basis is the BUILD Act (22 U.S.C. ss 9612), which authorises political risk insurance for development "projects" in "less developed countries." It contains no mechanism for $352 billion in wartime shipping coverage (JP Morgan, 5 March 2026). As of publication, no vessel has transited Hormuz under DFC cover.
The parallel fleet is already forming. China's Sinokor acquired 35 of 45 VLCC sale-and-purchase deals in 2026, assembling a fleet of 120-130 VLCCs — now the world's largest (Argus Media). Beijing is not waiting for Washington to fix the insurance market. It is building one that does not need it.
The insurance market closed Hormuz faster than any navy could have. The question nobody in Washington is answering: what reopens it?
