Twelve leading P&I clubs (Protection and Indemnity mutuals, which carry a shipowner's third-party liabilities) cancelled their ancillary regional war-risk extensions after reinsurers, the insurers who take slices of rare catastrophic risk off other insurers, withdrew their backing. The clubs then arranged replacement buyback cover, war-risk insurance repurchased at current market prices, within three days. Lloyd's List reported the sequence in its daily briefing on 18 August1.
The cancelled class covers specialist war-risk liabilities rather than core Protection and Indemnity, which remained available throughout. Any account of Gulf shipping as uninsured overstates it. The same briefing recorded three ADNOC vessels targeted in the preceding week.
One reading has an insurance market behaving exactly as designed: cover withdrawn the moment the reinsurance layer vanished, cover repurchased at a fresh price seventy-two hours later. The other reading follows a single owner through the week, from continuous cover, to a lapsed policy, to a repriced one. Nobody budgets for that middle stage, and neither reading can be settled from outside the market.
What can be examined is the material the underwriter had when setting the new price. Pricing a Hormuz voyage means pricing the chance of a hit against how many voyages actually take place, and that figure arrived in irreconcilable versions this week. It also means reading a sanctions register whose most recent Iran entry, a 35-party shadow-banking designation dated 14 August, reached the gazette as scanned images rather than machine-readable text. Frequency data and legal data both degraded together, and war-risk premiums travel down the chain into the delivered cost of crude, gas and containerised freight.
