Iran Conflict 2026Background
War risk coverage is the marine insurance clause that pays when a vessel or cargo is lost through acts of war, mine strikes, or hostile seizure. Standard P&I and hull policies exclude war; shipowners buy it separately through syndicates at Lloyd's of London and mutual clubs such as Skuld, the London P&I Club, and the American Steamship Owners Mutual P&I. Premiums surge whenever a waterway becomes contested; the Persian Gulf has triggered war risk exclusions in every major tanker conflict since the 1980s Tanker War.
Three major P&I clubs cancelled Gulf and Gulf of Oman War risk coverage with 72 hours' notice from 2 March, effective midnight 5 March, leaving vessels without the insurance required to obtain port clearance or financing. VLCC freight rates hit an all-time high of $423,736 per day as shipowners priced the elevated risk into charter rates.
The US Development Finance Corporation stepped in with government-backed cover for US-aligned shipping, a scale of state intervention not seen since the US War Risk Insurance Act of 1914. Roughly 60% of Gulf oil flows to Asia, and Chinese, Russian, and Indian tankers operate under separate commercial arrangements, leaving the collapse unresolved for the bulk of Gulf trade.
