Reinsurers walked off the Red Sea and the clubs started insuring each other
When the global reinsurance market refuses a risk, the world's ship insurers fall back on their own promise that no member pays alone.
On August 13, Gard's office in Bermuda and Norway's Skuld sent notices to shipowners whose policies touch one of the busiest waterways on earth: from midnight on August 16, war risks cover for a widened zone stretching across the southern Red Sea, the Gulf of Aden and a broad slice of the western Indian Ocean would be gone, pulled at the demand of their own reinsurers (Royal Gazette, Aug 13). Within days UK P&I, London P&I and NorthStandard had issued notices of their own, and Steamship Mutual followed as the last big name to cancel (Ship & Bunker, Aug 13). The trigger was not a new attack but a stack of cancellation notices from the global reinsurance market, which decided it no longer wanted the exposure.
Here is the contradiction. The same fortnight, Suez Canal traffic reached its highest level in more than two years, nearly 1,090 transits in four weeks, and Maersk says more than 30% of its Asia-Europe volumes that had been routed around the Cape of Good Hope are back through Suez (Lloyd's List Intelligence Red Sea Brief, Aug 20). Container lines are returning to a corridor whose insurers just walked away. Ships can sail the route again precisely because someone else agreed to absorb what the reinsurers refused.
To see who that someone is, you have to understand the strange machine called the International Group of P&I Clubs. Thirteen mutual associations, owned by their shipowner members, insure the liabilities of most of the world's ocean fleet. Each club keeps the first $10 million of any claim; claims beyond that are pooled among all thirteen clubs; and above $100 million sits the General Excess of Loss contract bought from the commercial reinsurance market in three layers reaching $2.35 billion, topped by a further $1 billion Collective Overspill facility that the clubs provide to each other out of their own pockets (International Group of P&I Clubs press release, Dec 17 2025). That overspill layer is the sentence in the headline made concrete: when everything commercial is exhausted, the clubs owe each other money.
What collapsed this month was narrower than the main tower but wider than it looks. The cancellations hit ancillary products, chiefly fixed-premium charterers' liability cover with war risk extensions, which sit partly outside the pooled system and depend on commercial reinsurance the clubs buy separately (Royal Gazette, Aug 13). The mutual core, the pooled tower, survived untouched. So the clubs did what mutuals do: they wrote buyback cover, reinstating the cancelled protection themselves for owners who must transit, priced case by case instead of through broad market increases (Lloyd's List Intelligence, Aug 20). The desk is insuring its own members against a risk the outside market declined.
The exclusions buried in those buybacks tell you who the market thinks will actually get hit. Saudi-owned, operated and flagged vessels face blanket exclusion under the new charterers' arrangements, while non-Saudi-linked tonnage remains coverable (Lloyd's List Intelligence, Aug 20). That is a direct read-through of the politics: the Houthis declared a naval blockade against Saudi Arabia on July 20, and Riyadh's Red Sea ports at Yanbu and Jeddah are its workaround for the Iranian pressure on Hormuz (Reuters, Jul 20). The insurance market has quietly drawn the same map the militaries drew, and priced one flag differently from all others.
The market priced the blockade, the clubs caught what fell, and Saudi ships sail the world's most dangerous strait knowing no one will pay for them.
Separate the weeks from the years. The trigger is the Houthi blockade declaration and the missile incidents that followed, including an unmanned cargo vessel struck off Al Mukha and written off as a total loss, plus two piracy hijackings near the Gulf of Aden inside four days (Lloyd's List Intelligence, Aug 20). The slow pressure underneath is that this is the second time this year reinsurers have pulled war risk capacity from the region; the first round came in March, when Gard and Skuld cancelled covers for the Persian Gulf and Gulf of Oman as the US-Israel-Iran conflict escalated (Royal Gazette, Aug 13). Each withdrawal has started higher up the risk ladder and reached further down into ordinary commercial policies.
The history that fits is the Tanker War of the 1980s, when Iranian and Iraqi attacks in the Gulf pushed Lloyd's war risk premiums so high that Kuwait's tankers could only keep moving under American flag and naval escort, in Operation Earnest Will. Then as now, the commercial insurance market did not fail loudly; it priced itself out quietly, and a state stepped into the gap with its own balance sheet. The difference this time is that the state being priced out is Saudi Arabia itself, and Washington shows no appetite to reflag anyone's crude. The counter-example argues the other way too: the clubs' pooled system, built in 1996 atop the International Group framework dating from 1974, has absorbed every shock thrown at it without a single call on governments, and the December renewal extended the top layer of shipowner protection from $2.1 billion to $2.35 billion (International Group press release, Dec 17 2025). A machine that resilient does not crack over a regional blockade.
Follow the money down the chain. First order: owners of non-Saudi tonnage keep transiting at roughly unchanged cost, because the clubs absorbed the gap, with at least 252 transits through Bab el-Mandeb last week, flat week on week though below the pre-blockade average of 296 (Lloyd's List Intelligence, Aug 20). Second order: Saudi crude finds itself with two exits, Hormuz constrained and Bab el-Mandeb now carrying a flag-specific penalty or no cover at all, forcing Riyadh to load at Yanbu, run dark, and exit north through Suez rather than south past Yemen (Lloyd's List Intelligence, Aug 20). Third order: if a major Saudi tanker loss does occur uninsured, the claim lands nowhere in the reinsurance market because there is no policy; it lands on the kingdom's own accounts, and on every cargo buyer who assumed the oil was insured.
The people who pay are easy to name. Egyptian canal revenue gets a reprieve as traffic recovers, still 41% below pre-crisis levels even now (Lloyd's List Intelligence, Aug 20). Shipowners pay case-by-case buyback premia instead of market rates, cheaper than March's panic but opaque. And the thirteen clubs' own members pay in the currency mutuals always use: the pooled obligation, the promise that one club's catastrophe belongs to all. Crude tanker owners, meanwhile, profit from the disruption, earning the strongest rates in two decades as rerouted barrels lengthen voyages (Lloyd's List Intelligence, Aug 20).
What confirms the read: more clubs extending buybacks into the autumn renewal season on terms the open market refused, and Bab el-Mandeb transits holding near current levels with non-Saudi tonnage fully covered. What breaks it: a single large hull loss in the excluded zone that forces the clubs to deny a claim outright, or a second wave of reinsurance cancellations reaching the pooled mutual tower itself. Either event ends the quiet arrangement within weeks, because the whole structure rests on losses staying small enough to absorb informally.
The judgment this story earns is older than any of the institutions in it. Insurance did not disappear from the Red Sea; it moved inward, from thousands of reinsurance balance sheets to thirteen mutuals betting their combined reserves that the war stays contained.
