3,000 vessels stranded in Middle East

The IMO confirms the largest maritime gridlock since the Second World War, with more than 3,000 vessels stranded on both sides of a closed Strait of Hormuz and no escort corridor in prospect.

Key takeaway

Port backlogs will take weeks to clear after Hormuz reopens — consumer shortages will outlast the ceasefire.

More than 3,000 vessels remain stranded across the Middle East, according to the International Maritime Organisation — tankers loaded with crude, LNG carriers, container ships, and bulk carriers trapped on both sides of a strait that carried roughly 21 million barrels of oil per day before 28 February. The number has no peacetime precedent. When the container ship Ever Given blocked the Suez Canal for six days in March 2021, approximately 400 vessels were held up. The Hormuz closure has lasted 22 days, and the vessel count is nearly eight times that figure.

The stranded fleet is the physical mechanism behind the supply figures. The IEA's March 2026 Oil Market Report recorded an 8 million barrel-per-day drop in global supply — the largest disruption on record 1. Iraq's force majeure on all foreign-operated oilfields and QatarEnergy's Force majeure on LNG contracts to Italy, Belgium, South Korea, and China have left tankers and gas carriers loaded with product and no discharge port accepting them. The 400 million barrels released from strategic petroleum reserves are, as the IEA itself stated, "a stop-gap measure" 2. Reserves replace volume on paper; they do not replace the movement of ships through a contested waterway.

The 22 nations that demanded Iran reopen the strait — tripling the seven-country group from days earlier — pledged no warships. Three successive joint declarations have used the phrase "readiness to contribute to appropriate efforts" without producing a single escort vessel. Every country Trump named for a coalition formally refused to send ships . For the crews aboard — many of them Filipino, Indian, and Bangladeshi seafarers on contracts written for commercial voyages, not indefinite war-zone anchorage — the declarations are immaterial. War-risk insurance policies are expiring, crew-change logistics in conflict zones have broken down before, and no flag state has announced repatriation. The vessels wait because nobody will move them and nobody will escort them.

Deep Analysis

In plain English

When 3,000 cargo ships cannot move, the goods they carry — oil, LNG, electronics, chemicals, food — stop reaching their destinations. Some ships are waiting to load in Gulf ports. Others are anchored offshore, unable to enter because ports are congested, dangerous, or uninsured for the voyage. Even if the conflict ended tomorrow and the Strait reopened immediately, all those ships would rush to unload at once, overwhelming ports that process vessels one at a time. Receiving ports in Europe, Asia, and the US would face weeks of queues and delays. This means the price increases and shortages from the conflict will continue to be felt for weeks or months after fighting stops — the economic pain has a long tail that follows the military timeline.

Deep Analysis
Synthesis

The 3,000-vessel figure counts only vessels physically present in the region. It does not capture the second-order cascade: each stranded vessel creates a slot gap at its scheduled destination port, disrupting container terminal sequencing that operates on just-in-time scheduling. The industry's concentration in mega-vessels (20,000+ TEU capacity) means each missing ship represents cargo volumes that previously required multiple smaller vessels — amplifying the slot disruption per vessel significantly beyond historical baselines established before the mega-vessel era.

Root Causes

The stranding reflects insurance market mechanics as much as direct military threat. The Joint War Committee's war-risk designation of the Persian Gulf means P&I clubs — which cover approximately 90% of global shipping tonnage through mutual indemnity arrangements — will not underwrite losses in the area. Without P&I cover, banks will not finance cargo under letters of credit, and carriers cannot legally operate. The military situation triggers the insurance response, which produces the commercial paralysis; the causal chain is indirect and will not reverse automatically when hostilities end.

What could happen next?
2 consequence1 risk1 meaning1 precedent
  • Consequence

    Port backlogs following Hormuz reopening will take 2–4 weeks to clear, extending consumer shortages and price pressure materially beyond any ceasefire date.

    Short term · Assessed
  • Risk

    Insurance market war-risk designations may outlast military operations, maintaining effective commercial closure after hostilities end through underwriter reassessment delays.

    Short term · Suggested
  • Consequence

    Aggregate demurrage costs of $90m–$300m per day are accruing against importers and will pass through to consumer goods pricing with a 4–8 week transmission lag.

    Immediate · Assessed
  • Meaning

    Just-in-time global supply chains lack the safety-stock buffer to absorb a disruption of this duration — retail-level shortages are a structural consequence, not a contingent risk.

    Short term · Assessed
  • Precedent

    The bifurcated insurance response — Western P&I clubs withdrawing while Chinese carriers potentially continue — may establish a durable model for sanctions-adjacent supply-chain splits in future conflicts.

Different Perspectives
IAEA
IAEA
Director General Rafael Grossi appeared in person at the UNSC on 19 May and warned that a direct hit on an operating reactor 'could result in very high release of radioactivity'. The session produced a condemnation record but no resolution, and the Barakah perimeter was already struck on 17 May.
Hengaw (Kurdish rights monitor)
Hengaw (Kurdish rights monitor)
Hengaw documented three judicial executions and the detention of Kurdish writer Majid Karimi in Tehran on 19 May, establishing Khorasan Razavi province as the newest geography in Iran's wartime judicial record. The organisation's Norway-based operation continues to surface a domestic repression track running in parallel with every diplomatic and military development.
India
India
Six India-flagged vessels conducted a coordinated cluster transit under PGSA bilateral assurances during the 17 May window, paying no yuan tolls. New Delhi's inclusion in Iran's state-to-state passage track insulates Indian energy supply without requiring endorsement of the PGSA's yuan-toll architecture or alignment with the US coalition.
Pakistan
Pakistan
Pakistan is the only functioning diplomatic bridge between Tehran and Washington. Its role is relay, not mediation in the settlement sense: it conveyed Iran's 10-point counter-MOU in early May, relayed the US rejection, and is now passing 'corrective points' in the third documented exchange of this sub-cycle without either side working from a shared text.
UK and France (Northwood coalition)
UK and France (Northwood coalition)
Twenty-six coalition members have published no rules of engagement eight days after the Bahrain joint statement; Lloyd's underwriters have conditioned war-risk reopening on written ROE from either Iran or the coalition. Italian and French mine-countermeasures deployments are operating on the in-water clearance task CENTCOM Admiral Brad Cooper's 90% mine-stockpile claim does not address.
Saudi Arabia
Saudi Arabia
Riyadh has not publicly commented on the Barakah strike or the 50-47 discharge vote. Saudi output feeds the IEA's $106 base case; the $5 Brent premium above that model reflects institutional uncertainty no Gulf producer can compress through supply adjustment alone.
