Supply Chain Action Points

Read this first — the conclusion, and the moves to make:

  1. By 20 June 2026, list every open booking on this lane with its cargo class and contract type, because priority runs by class and your position is set by the class, not by the booking date.
  2. By 24 June 2026, obtain in writing from each carrier whether the corridor requires prior permission and who applies for it, since a permission-based transit changes what your force majeure notice can honestly say.
  3. By 30 June 2026, ask every carrier you use to state whether it has reinstated war risk cover for this lane and from which date, and keep the answers as a dated log, because reinstatement is per underwriter and those fragments are your only early warning.
  4. By 7 July 2026, quantify the per-container carrying cost of a three-week extension at your actual goods value using the 6% and 45-dollar assumptions above, and set it as the figure at which the delay is escalated to a decision instead of absorbed.
  5. By 14 July 2026, put a written position on the service charge question to your carrier naming who bears an unspecified charge if one is levied, because a charge with no named bearer is disputed after the invoice and costs more than the charge.

Summary

Industry experts warn that full normalization of Strait of Hormuz shipping will take weeks rather than days despite the US-Iran peace deal signing set for June 19 in Switzerland. Lloyd's List Intelligence VP Adam Sharpe described the most likely scenario as a phased restart with traffic-management mechanisms involving Iran and Oman. Key unresolved issues include whether vessels need prior permission, whether Iran will impose service charges, whether foreign naval escorts are accepted, and whether mines require formal clearance. Kpler estimates 118 tankers are stranded in the Persian Gulf with a 10-15 day backlog to clear. Insurance remains a critical bottleneck -- underwriters want evidence of stable, predictable operating conditions before reinstating coverage. Goldman Sachs lowered its Brent forecast to $80/barrel for Q4 2026 but warned near-term supply recovery is gradual. Prioritization is expected for oil tankers and LNG carriers, potentially delaying container and other cargo transits.

The Analysis

The memorandum is scheduled for signature in Switzerland on 19 June, and attention has already moved to what follows it. Lloyd's List Intelligence reads the likely shape as a phased restart under traffic management involving Iran and Oman. That is probably right, and it is also the least legally settled of the available outcomes, because phased means somebody decides the order, and that somebody is not your contract.

Four questions are listed as unresolved: whether vessels need prior permission, whether Iran will levy service charges, whether foreign naval escorts are accepted, and whether the mines require formal clearance. Read them as a list of conditions precedent rather than a list of uncertainties. Each one, answered a particular way, changes what kind of act a transit is.

Take the permission question first, because it changes the character of everything else. If a vessel may transit by right, a delay is a performance problem and your contract has tools for it. If a vessel may transit only with prior permission, every voyage is a licensed act, and a licence is discretionary by construction: it can be granted late, granted conditionally, or withdrawn with no change in the physical facts. That distinction, not the mine count, decides whether your force majeure notice is honest. The service charge question is smaller but has no contractual home, which makes it worse in practice: a new charge with no named bearer gets argued about after the invoice, and the argument costs more than the charge. Escorts raise a flag state question, because accepting a foreign naval escort is a decision your flag administration makes and your hull underwriter prices. Clearance is the only one of the four that is purely factual, and the only one that can be evidenced by a document.

On the physical side, the numbers fit a slow restart rather than a fast one. Kpler counts 118 tankers stranded in the Persian Gulf and estimates 10 to 15 days to clear the backlog. Divide one by the other and the implied throughput falls between eight and twelve tankers a day, which is arithmetic on the reported figures rather than a reported figure itself, and it is the number to hold: the corridor can move hulls faster than it can move paperwork. That gap is why the restart is phased. Nothing needs rebuilding. Something needs deciding, repeatedly, and the decided items accumulate at the speed of an administration rather than the speed of a pump.

The sentence that matters most for a container importer is buried near the end: prioritisation is expected for oil tankers and LNG carriers, potentially delaying container and other cargo. Read that as a rule, not a forecast. It creates classes of traffic with different claims on one corridor, and your class is at the back. Container cargo has no entitlement to a slot here and no rate buys one, because the allocator is not a market. A shipper holding a service contract with a guaranteed allocation has a promise about capacity on a service that assumes a corridor is open; it does not have a promise about the corridor. That is the gap where the damage happens, and it is a gap in the contract rather than in the schedule. Small exporters feel it first because they book late and have no escalation path. Large ones feel it as a planning problem, which is a better problem to have.

Timing deserves its own treatment because two dates are being confused. The tanker backlog clears in 10 to 15 days from the moment the corridor actually functions. Your container booking does not clear then; it clears when your class opens, and that date has not been set by anyone. So the honest model has two inputs, the backlog duration and the class opening, and the second is currently unknown rather than merely uncertain. Goldman's cut of the Brent forecast to 80 dollars for the fourth quarter of 2026 sits on the same reading: the market expects the barrels back, gradually, and is not pricing a fast restoration. When a bank marks a gradual recovery and a physical operator marks 10 to 15 days, they are describing different objects, and neither of them is your booking.

Here is what the coverage does not put together, and it is the part that should change your planning. Reinstatement of cover is treated as a single event that happens once conditions stabilise. It is not one event. Each underwriter decides separately, on its own book, and each wants its own evidence, so the market reopens in fragments over days or weeks rather than at a moment. The practical consequence is that the first carriers back are not the cheapest or the largest, they are the ones whose underwriters moved first, and they hold the cargo to themselves for the interval. That interval is where a shipper either locks capacity or watches it go. It also means the visible indicator is not a headline about reopening but the appearance of quotes with war risk included; a market with no quotes is not a market about to reopen, it is a market where nobody has decided yet.

Put a number on the delay, with the assumptions flagged as mine. Take a 40-foot container of consumer goods with a declared value of 60,000 dollars, three weeks of additional transit, and carrying cost at 6% a year. The capital cost of the extra three weeks is about 208 dollars. Add destination storage at 45 dollars a day for 21 days, 945 dollars, and the booking carries roughly 1,150 dollars it did not budget, which is 1.9% of the goods value before any freight increase. Now apply the same days to a tanker: two million barrels at 81 dollars is 162 million of cargo, and one day of delay on that cargo outweighs the entire container booking in absolute terms. Whatever allocates the corridor, a state mechanism or a plain queue, will clear the tanker first every time, and it will be right to. That is the arithmetic beneath the prioritisation sentence, and escalation does not change it.

Reverse the four questions and see what would have been different. Had the text answered them, permission by published rule rather than by case, charges scheduled rather than unspecified, escorts authorised in advance by flag administrations, clearance certified by a named body, the restart would be a timetable instead of a negotiation, and container cargo could be given a date. Because the text leaves them open, every booking on this lane is priced against an unallocated risk, and the party carrying it is whoever holds the cargo when the queue moves. The conclusion holds while those four stay open. Answer the permission question with a published rule and the rest becomes scheduling, which is manageable. Leave it case by case and every voyage remains discretionary, and no service contract, no slot guarantee and no escalation clause can convert a discretion into an entitlement.
