500 ships idle as Hormuz stays shut

Zero new tankers crossed Hormuz in the 24 hours after Trump's signature; more than 500 ships stayed anchored as Bimco called a crossing very risky.

Key takeaway

Brent priced an open strait that no tanker actually crossed; insurers still block transit.

Zero Hormuz tankers transited in the 24 hours after Trump's 16 June signature, despite his declaration that the strait was open. The two crossings logged on 15-16 June were toll passages under the Islamic Revolutionary Guard Corps (IRGC) authority, Iran's military force that controls mine routes and passage conditions, not a reopening . More than 500 ships remain parked in the Gulf 1. BIMCO, the world's largest shipowner association, calls a crossing "very risky": the floating mines are still live, no IRGC order has cleared the lanes, and not one Protection and Indemnity (P&I) club, the London-based mutual marine insurers, has lifted its Hormuz war-risk exclusion 2.

The insurance point drives the lanes more than the mines do. A tanker without P&I cover cannot dock, because terminals and lenders refuse an uninsured hull. The blockade now runs through London insurance underwriters as much as through Iranian mines, and every owner knows it. Jakob Larsen, BIMCO's chief safety officer, said owners "still consider it very risky to commence transits at this point" while the mines stand uncleared.

Brent Crude, the global benchmark that prices roughly two-thirds of internationally traded oil, fell to between $78.82 and $81.55 on the signing, down as much as 5 per cent 3, near the two-month low it touched a week ago on deal optimism . Markets priced the expectation of an open strait. No moving ship lay behind the fall, because the lanes held zero new transits. The price moved; the cargo did not.

Deep Analysis

In plain English

When a ship sails through a war zone, it needs special war-risk insurance. The P&I clubs, mutual insurance associations based in London, provide this cover for roughly 90 per cent of the world's ships. They said on 16 June that the Hormuz strait is still too dangerous to cover, because Iranian military mines remain in the water and nobody has officially certified them as swept. Without that cover, a shipowner who loses a vessel in the strait cannot claim for the loss. No credible insurer will touch an active mine zone. This is why 500 ships are sitting in the Gulf, not because their owners do not want to move, but because sailing uninsured through an uncleared mine field is commercially and legally impossible.

Deep Analysis
Root Causes

The 500-ship backlog and zero-transit outcome have two distinct root causes. The mine threat is physical: CENTCOM's own assessment by mid-May was that 90 per cent of Iran's naval mine stockpile was warehoused, not in-water, but the remaining deployed mines have not been certified as swept. Bimco's Jakob Larsen cited active mines as the primary safety barrier.

The P&I club constraint operates through the International Group of P&I Clubs, which covers roughly 90 per cent of the world's ocean-going tonnage. The group sets a collective de-risk bar that no individual member club can unilaterally lower without triggering reinsurance withdrawal by the London market. P&I clubs cannot issue standard hull and liability cover for a zone the Lloyd's Joint War Committee lists as enhanced-risk without a UN resolution or government certification of safety.

What could happen next?
  • Consequence

    P&I de-listing of Hormuz requires mine clearance certification or a UN resolution; the 60-day nuclear talks window does not address either condition.

  • Risk

    Oil markets pricing a reopening that has no ships behind it face a correction risk if Friday's ceremony also fails to produce mine clearance progress.

Different Perspectives
India
India
India buys more Saudi crude than any other country and has 2.5 million nationals working in the kingdom, so a $100 Brent and a live strike on Saudi tankers reach New Delhi through both fuel bills and remittance risk. Neither channel has an alternative route the way Saudi Arabia's own pipeline does.
Qatar
Qatar
Qatar co-authored the four-mediator ten-day ceasefire proposal alongside Egypt, Pakistan and Oman, centred on resuming Hormuz navigation, while separately pursuing its dated compensation claim against Iran at the UN Security Council filed on 21 July. Doha is mediating and litigating in the same week.
Israel
Israel
Israeli intelligence, reported by the Wall Street Journal, assesses Iran moved thousands of centrifuges and part of its roughly 440kg enriched-uranium stock into Pickaxe Mountain after the June 2025 strikes on its three main nuclear sites. Some of the US refuelling aircraft now deploying to the region are bound for Israeli bases and Ramon Airport.
Houthis
Houthis
Yahya Saree announced the missile and drone strikes on the Encelia and Layla on 22 July as enforcement of the embargo his forces had declared by radio warning alone two days earlier. Six vessels already turned back on the broadcast; the strike shows Houthi forces will use weapons once warnings stop working.
Saudi Arabia
Saudi Arabia
Saudi Arabia's state news agency confirmed only a fire on the Encelia's bow, with the crew safe; the Layla strike remains unconfirmed by Riyadh. The kingdom built its Petroline pipeline specifically to bypass Hormuz through the Red Sea, so the tanker fire lands on the route Riyadh had already spent billions escaping.
United States
United States
Washington is weighing both ten-day proposals but wants a longer truce than either offers, and moved F-16 and F-35 jets plus refuelling aircraft into the region while it decides. That deployment, not Trump's Pickaxe Mountain remarks, is the measurable US action, buying options for the day talks fail rather than betting on them.
