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
South Korean financial markets
South Korean financial markets
South Korea, which imports virtually all its crude oil, is absorbing the war's economic transmission most acutely among non-belligerents. The second KOSPI circuit breaker in four sessions — with Samsung down over 10% and SK Hynix down 12.3% — reflects an industrial economy unable to reprice energy costs that have risen 72% in ten days. The market response indicates Korean industry cannot sustain oil above $100 per barrel without margin compression across manufacturing, semiconductors, and shipping.
Migrant worker communities in the Gulf
Migrant worker communities in the Gulf
The first confirmed civilian deaths in Saudi Arabia — one Indian and one Bangladeshi killed, twelve Bangladeshis wounded — fell on communities with no voice in the military decisions that placed them in harm's way. Migrant workers live near military installations because that housing is affordable, not by choice. Bangladesh and India face the dilemma of needing to protect nationals who cannot easily leave a war zone while depending on Gulf remittances that fund a substantial share of their domestic economies.
Azerbaijan — President Ilham Aliyev
Azerbaijan — President Ilham Aliyev
Aliyev treats the Nakhchivan strikes as a direct act of war against Azerbaijani sovereignty, placing armed forces on full combat readiness and demanding an Iranian explanation. The response is calibrated to maximise international sympathy while stopping short of military retaliation — Baku cannot fight Iran alone and needs either Turkish or NATO backing to credibly deter further strikes.
Oil-importing nations (Japan, South Korea, India)
Oil-importing nations (Japan, South Korea, India)
The Hormuz closure is an existential threat. Japan, South Korea, and India receive the majority of their crude through the strait — they will bear the heaviest economic cost of a war they had no part in.

Neutrality was possible when the targets were military. 148 dead schoolgirls made it impossible — no government can explain that away to its own citizens.
Turkey
Turkey
Has absorbed three Iranian ballistic missile interceptions since 4 March without invoking NATO Article 5 consultation. Each incident narrows Ankara's political room to continue absorbing without Alliance-level response.
