LONDON – A $150 million crude carrier transiting the Strait of Hormuz is paying up to $7.5 million per voyage in war risk insurance, an amount that at pre-crisis rates would have covered fifteen to twenty years of equivalent coverage. The Islamabad MoU was signed on June 17. The premium has not come down.
Lloyd’s launched a new marine war risk consortium two days after the MoU, with Chubb as lead underwriter, offering up to $200 million each in hull, Protection and Indemnity, and cargo coverage. The consortium was not a price signal. It was a capital supply measure: the conflict had removed so much private market coverage from the strait that a new pool was needed to prevent the insurance market from seizing entirely. The most extreme rates from the peak of the conflict, $10 to $14 million in war risk cover for a single five-year-old very large crude carrier reported by Lloyd’s List, have moderated. The JWC designation that drove them has not.
The Lloyd’s Joint War Committee, which maintains the list of maritime high-risk zones, expanded its coverage to include the entire Persian Gulf following the February 28 strikes. The committee’s standard for removing or narrowing a designation is that the threat must have “materially diminished.” The Lloyd’s Market Association stated after the Doha round on July 1: “The region remains at heightened risk with none of the underlying tensions resolved.” The designation historically takes years to reverse under normal circumstances. The Hormuz case presents circumstances the JWC has not previously encountered: an active toll system, an IRGC corridor that struck a commercial vessel on June 25, and parliamentary legislation in Tehran that would codify those conditions into permanent domestic law.
The scale of the market disruption is best understood from the baseline. War risk premium for a Gulf tanker voyage ran at approximately 0.1 percent of hull value before February 28, according to gCaptain. By mid-March it had reached 2.5 percent per seven-day period. Some stranded tankers paid up to 10 percent of hull value for a single transit. The post-ceasefire rate is approximately 1 percent per voyage: ten times the pre-crisis baseline, and still pricing in a risk the JWC has formally designated as unresolved. Most P&I clubs, the mutual insurers that cover third-party liabilities for roughly 90 percent of the global merchant fleet, cancelled war risk extensions within seventy-two hours of the conflict beginning. They have not reinstated on the old terms.
The market’s pricing problem is structural, not cyclical. Jake Scott, chief operating officer of Easterly Clear Ocean, told gCaptain that insurance costs of $10 million for some larger vessels represent only the premium itself, not crew compensation or additional risk adjustments. That overhead eliminates entire vessel classes from the route. A $4 million round-trip fee prices Aframax tankers, the workhorse of short-haul crude movements, out of the market. The ships that can absorb the cost tend to be the very large crude carriers with the balance sheet to self-insure partial risk. That concentrates remaining Hormuz traffic in a narrower slice of the global fleet, which further depresses the competitive pressure on insurance rates.
The US government moved to address the coverage gap in April. The International Development Finance Corporation established a reinsurance backstop of approximately $20 billion in coverage, partnering with Chubb across hull, cargo, and liability risks for vessels in the strait. JPMorgan estimated roughly 329 vessels operating in the Persian Gulf required coverage representing approximately $352 billion in exposure that private markets had effectively withdrawn. The government facility covers a fraction of that exposure and does not set market rates; the JWC designation does. Government reinsurance backstops availability without reducing price, and the JWC will not reduce price by removing or narrowing its designation until its conditions are met.
Those conditions point directly at what the Doha talks deferred. The Hormuz toll legislation advancing through Iran’s parliament, with a mid-August enforcement target, is precisely the kind of codified sovereign claim that qualifies as an unresolved underlying tension under the JWC’s assessment framework. The IAEA’s verification access, blocked by Iranian law from the three damaged enrichment sites, is the second condition the market watches. Neither was addressed in the July 1 Doha round. Both remain open.
The traffic recovery data shows what the insurance regime means in practice. Before the conflict, roughly 178 ships transited the strait daily. By June 23, the first AIS-visible transits through the central corridor were recorded since the war began, 21 in a single day. By June 30, Kpler counted 34 crossings. The weekly total for the period ending June 23 was 133 vessels compared to 53 the previous week, a near-tripling that reflected the ceasefire’s effect on operator willingness to enter the route. But traffic composition had shifted: Gulf state-owned tonnage was dominant, Iran-linked vessels had dropped from 69 percent of total throughput in March to 18 percent in June, and operators were working voyage by voyage under individually negotiated coverage at rates that make the route viable only at very high freight premiums.
Iran’s oil revenue during the sanctions waiver window is being compressed by exactly this mechanism. The 20 percent premium over blockade-era prices that Iranian crude is now commanding is real. It is bounded above by insurance costs that arrive at the buyer as freight overhead and suppress the final price Iran can command in legitimate markets. The diplomatic track and the insurance market are measuring the same conflict by different clocks. The MoU set an August 21 deadline. The JWC operates on a historical reversal timeline that, in other theaters, has extended to years after formal resolution. The market is not waiting for Doha; it is waiting for the specific conditions Doha has not yet produced.
