Hormuz logged two ships, not 94

Two ships transited the Strait of Hormuz across 15-16 June, against a pre-war rate of 94 a day. The memorandum promises a full reopening on Friday, yet not one major operator has routed a tanker through on the strength of it.

Key takeaway

Markets are pricing the gap between the signed deal and a moving tanker, not the deal itself.

Two ships transited the Strait of Hormuz across 15-16 June, the 33-kilometre Gulf chokepoint that carries about a fifth of the world's seaborne oil.⁠1 Before the war the strait handled roughly 94 vessels a day. The newly signed memorandum promises a full reopening when the deal is formalised in Geneva on Friday, yet no major operator has sent a tanker through on the strength of it.

Underwriters, not nerves, keep the tankers in port. Protection-and-indemnity clubs, the mutual insurers that cover a vessel's third-party liability, will not underwrite a Hormuz crossing while the IRGC, Iran's Islamic Revolutionary Guard Corps, still runs the toll authority it set up on 5 May and has refused to dissolve. Iran reasserted its sovereignty over the strait and its right to charge for passage the day of the signing, so the clubs have no security grounds to reinstate cover. Without cover, no major charterer sails. Jotaro Tamura, a shipping executive quoted by the Financial Times, said operators will wait weeks until conditions change "on the water".⁠2

Brent Crude settled near $83.61, down a further 4.3 per cent and below the two-month low it had already reached when the deal first looked probable. That is not a peace dividend. Traders are pricing the distance between signed paper and a moving tanker, discounting the chance that Friday produces actual flows rather than a ceremony. Lower crude eases fuel costs for importers, but with the toll authority intact and the underwriting absent, the relief rests on cargoes no one will yet insure.

Deep Analysis

In plain English

the strait of Hormuz is a narrow waterway between Iran and Oman through which roughly one-fifth of the world's oil travels. Before the war, about 94 ships passed through each day. On 15-16 June, only two did. Shipping companies cannot send a vessel worth hundreds of millions of pounds into the strait without insurance covering seizure or damage. Protection-and-indemnity clubs, which cover almost all large cargo ships, have refused to write that cover since March. The major insurance clubs, which together cover almost all big cargo ships, will not write that cover while Iran's military still controls the waterway and there is no written, legally binding safety framework. A signed-but-unpublished diplomatic document does not change that. Until the insurance question is resolved, oil tankers will wait outside regardless of what politicians announce.

Deep Analysis
Root Causes

P&I cover for Hormuz transits ceased because two separate legal conditions remain unmet. First, Lloyd's Joint Hull Committee guidance, circulated on 19 May 2026, requires either a written rules-of-engagement document from the 26-nation coalition or a published PGSA (Persian Gulf Strait Authority) transit framework before the market will price the route.

Neither exists. Second, the IRGC's Persian Gulf Strait Authority, created 5 May, has registered zero commercial vessels; the MOU does not dissolve the PGSA, meaning the authority that P&I clubs treat as an extortion mechanism remains operational on the day of the signing.

The market's assessment is therefore that paper diplomacy has not changed the operational facts: the IRGC can still board, delay or seize vessels in Iranian territorial waters, and no insurer has indemnity protection against that outcome.

What could happen next?
  • Consequence

    P&I clubs will not restore cover until either a UN Security Council resolution or a published government certification of safe transit exists, conditions that neither the MOU nor the Geneva ceremony address.

    Short term · Assessed
  • Risk

    If a vessel transits without P&I cover and is seized or damaged, the resulting uninsured loss falls on the ship owner directly; no government indemnity mechanism currently exists.

    Immediate · Assessed
  • Opportunity

    Iranian crude re-entering the market at full pre-war volume would release approximately 1.5 million barrels per day, worth roughly $4-5 per barrel on the Brent price, if Hormuz fully reopens within a 60-day window.
