Supply Chain Action Points
Read this first — the conclusion, and the moves to make:
- By 25 June 2026, produce a one-page register of every booking on your file that transits this strait, with hull name, flag, the war risk clause reference and the percentage currently quoted, because the three permissions are granted per voyage and a lane-level view hides which of your bookings lack the commercial one.
- By 30 June 2026, obtain in writing from your underwriter or broker whether cover for this transit is per voyage or per period, what notice they hold to withdraw it, and what evidence they require before reinstating it, because that reinstatement condition is the binding clock and it is answerable in writing.
- By 3 July 2026, obtain the executed text of the agreement and its annexes and log each operative clause against the four open questions, permission, service charges, escorts and mine clearance, because a clause absent from the text is not a commitment you can rely on in a dispute.
- By 10 July 2026, revisit every force majeure notice and every delivery commitment on this lane and extend or withdraw each one on the basis of the written insurance position rather than the news, with a target of zero commitments reopened without cover confirmed.
- By 17 July 2026, set a review trigger at the point your forwarder returns a war-risk-inclusive quote for the lane, and re-run the exposure register within five working days of it, because that quote rather than the announcement marks the commercial reopening for you.
Shipping companies welcomed the US-Iran peace deal to reopen the Strait of Hormuz after a three-month closure, but full restoration of transit remains dependent on mine clearance, insurance reinstatement, and navigational safety assessments. Kpler data shows 483 vessels are effectively trapped in the Arabian Gulf, including approximately 220 tankers. BIMCO's chief safety officer Jakob Larsen stressed that mine-free routes and credible assurances from both sides must be established before full traffic resumes. Only 14 total crossings were recorded over the weekend. Analysts estimate 4-8 weeks for full normalization, with the Pentagon previously warning mine clearance could take up to six months. War risk insurance premiums remain elevated at 1.0%, and owners, charterers, and insurers require confidence in safe-passage procedures.
The Analysis
The Strait of Hormuz is being described as reopened. Strictly speaking, what exists is a cessation of hostilities with a shipping understanding attached, and that is a different instrument from a right of passage. A cessation stops the parties shooting at each other. It does not entitle your vessel to transit, restore the hull war cover that was withdrawn, or turn the strait into a safe port in the sense your charterparty means by those words.
Five numbers carry the story. Three months of closure. Fourteen crossings across the weekend. 483 vessels still inside the Arabian Gulf, about 220 of them tankers. Four to eight weeks for full normalisation, against a Pentagon warning earlier that mine clearance alone could take six months. And war risk premium at 1.0%. Those figures do not point at one date, and the gap between them is where your exposure sits.
Begin with what the instrument actually governs. An agreement of this kind binds two governments. It addresses whether they attack each other's ships, and here whether a corridor is cleared and policed by both sides. It does not bind a hull underwriter, a protection and indemnity club, a flag state, or the master. Each of those holds a separate veto that a signature cannot lift. Three permissions have to line up before a container moves: the political one, which now exists in outline; the physical one, which is a surveyed route with a clearance record behind it; and the commercial one, which is an underwriter willing to write that particular voyage at that particular rate. One of the three has been granted. The other two are decided by different people on different evidence, and neither is moved by a ceremony.
Fourteen crossings is the most informative figure in the report and the least examined. With 483 hulls inside the Gulf, ship supply is not the constraint; there is more tonnage waiting than the corridor can absorb in a month. Throughput is limited because each voyage needs its own underwriting decision and its own safe-passage procedure, and those are made one at a time. BIMCO's chief safety officer framed the condition properly when he said mine-free routes and credible assurances from both sides had to exist before full traffic resumes. Treat that as a condition precedent rather than a hope. A condition precedent is not satisfied by a communique. It is satisfied by a document a charterer can hand the master when he asks, in writing, whether the route is clear and whether the additional premium has been paid. Until the document exists, the answer from the bridge is no, and the answer from the underwriter is a price rather than a refusal, which reads like progress and is not.
Exposure sorts by hull size and by who controls the ship, not by how much cargo you have. An importer with one or two container bookings a month on this lane holds no lever. It does not pick the vessel, does not see the war risk clause, and learns about the reopening from a rolled booking notice rather than from a headline. A charterer with a book of contracts of affreightment sits elsewhere entirely: it can read the clause, argue over who bears the additional premium, and decide whether to instruct the vessel to proceed. Same water, same week, two legal positions that share nothing.
Direction adds a second split. Cargo leaving the Gulf competes with crude for one corridor and one survey team, so a machinery or food exporter outbound is sequenced behind tankers whether anyone admits it or not. Cargo arriving is gated by something duller: whether the discharge port and its hinterland are working, because a berth that cannot take the box costs more days than a strait that cannot be crossed. The thinnest position in either direction belongs to the FOB buyer, who has paid for goods it does not control and holds no contract with whoever makes the voyage decision.
The clocks do not agree. The political clock expired at signature. The physical clock is clearance, four to eight weeks on the analyst estimate and up to six months on the Pentagon's earlier warning, and it starts when a survey vessel begins work rather than when the deal is announced. The commercial clock is reinstatement of cover, and that is the one that decides when your cargo actually moves. Underwriters, as reported, want evidence of stable and predictable operating conditions first. Evidence is a track record, and a track record can only be built out of transits that have already happened without incident. Clearance, then transits, then evidence, then reinstatement, then rates. The four-to-eight weeks covers the first link.
Which brings up the point the coverage leaves out, and it should change how you date your own plan. The reopening is not a switch that flips once. It is a per-voyage underwriting decision repeated several hundred times, and the speed at which those decisions turn favourable depends on how uneventful the previous batch was. The visible recovery will therefore not look like a curve. It will look like a cluster of ships moving, a pause while the first movers complete cleanly, then a step. Anyone waiting for a headline that says normalised will still be waiting while their competitors are booking. The signal worth watching is whether your forwarder can obtain a quote that includes war risk at all, and at what percentage. The day a quote comes back with a number on it instead of an exclusion is the day the commercial reopening began for your lane, and it will come before the announcement everyone is currently reading.
Run a number, and take the assumptions as mine rather than the report's. Hull value of 60 million dollars, with the 1.0% treated as a per-transit charge on that value; confirm that on your own slip rather than trusting me. That is 600,000 dollars a transit, not a year. Against a large container ship carrying perhaps 150 million of cargo, another assumption of mine, it is 0.4% of cargo value, unwelcome but survivable. Against a small general cargo ship with 8 million of hull and 6 million of cargo, the same 600,000 is a tenth of the cargo value before freight, and that trade does not absorb a tenth. One arithmetic difference, two outcomes, and it explains why a reopening announced for everybody will in practice open first for big tonnage and last, or never, for small.
Reverse it and the edge of the conclusion shows. Had the deal instead named a corridor, published coordinates, commissioned a third-party survey with a published result, and allocated liability for a mine strike between the two governments and the transiting vessel, the insurance lag would compress, because underwriters would be pricing a defined risk with a named bearer. It did none of that. What it produced is an agreement whose effect depends on four or five subordinate administrative decisions, which is why the same text can sit behind a 1.0% rate one week and a materially higher one the next without a word changing.
Your exposure is not the deal. It is the space between the deal and those decisions. That holds while the corridor stays a corridor and both sides keep guaranteeing non-interference. If it holds, the rest is queueing and the only question is your place in it. If it does not, four to eight weeks is a floor on clearance and says nothing about cover, and 483 hulls stop being a backlog and become floating storage. That second branch is not the gloomy case. It is the case the instrument, as written, fails to exclude.
