Strait of Hormuz Crisis: Global Energy and Food Security Catastrophe

The Iran war triggered closure of the world's most critical energy chokepoint, causing the largest supply disruption since the 1970s. Iran closed and mined the strait. Despite a nominal ceasefire, the US and Iran exchanged fire in the strait on May 7, 2026: after Iranian attacks on three US destroyers, the US struck what CENTCOM called military sites at Qeshm and Bandar Abbas, while Iran said civilian areas were hit (unverified); a cargo vessel was hit, killing one sailor. Copernicus satellite imagery showed a large oil slick (71 sq km) near Kharg Island; its source is disputed and it has not been attributed to US strikes. Iran declared the ceasefire violated; the strait remains effectively closed.

Posture note
Iran directly closed and mined the strait; the US is responsible for initiating the war (see the aggression entry), not for assisting Iran's closure. The foreseeable humanitarian consequences of attacking Iran — including the near-certain disruption of the strait — bear on the gravity of the aggression. No US international crime specific to this entry is established; Iran's claim that the May 7 US strikes hit civilian areas has not been independently verified.
Victims
Civilian populations across the Gulf states facing food and energy shortages. Over 220,000 Indian nationals evacuated. Global populations affected by energy price spikes. Workers and migrants stranded in the region.
Alleged responsible parties
Iran (direct closure), US and Israeli militaries (war that triggered the closure), Trump administration (initiated the war without congressional authorization)

Key points

  • The Strait of Hormuz — through which approximately 20 million barrels of oil pass daily, representing 20% of global seaborne oil trade — was effectively closed starting March 4, 2026.
  • Tanker traffic dropped by approximately 70%, with over 150 ships anchoring outside the strait to avoid risks.
  • Oil production of Kuwait, Iraq, Saudi Arabia, and the UAE collectively dropped by at least 10 million barrels per day — the largest supply disruption in the history of the global oil market.
  • Brent Crude surged past $120 per barrel.
  • 70% of Gulf Cooperation Council food imports were disrupted, causing 40-120% spikes in consumer prices and a 'grocery supply emergency.'
  • Over 220,000 Indian nationals were evacuated from the GCC region and Iran.
  • The head of the IEA called the situation 'the greatest global energy security challenge in history.'

What Happened

The US-Israeli war on Iran, launched February 28, 2026, triggered the closure of the Strait of Hormuz — the narrow waterway through which approximately 20 million barrels of oil pass daily, representing roughly 20% of global seaborne oil trade. The head of the International Energy Agency called the resulting crisis "the greatest global energy security challenge in history."

The Closure

Following the start of hostilities, Iran's Islamic Revolutionary Guard Corps (IRGC) issued warnings prohibiting vessel passage through the strait. Tanker traffic dropped by approximately 70%, with over 150 ships anchoring outside the strait to avoid risks. By March 11, Iran declared that "not one litre of oil" would pass through.

Energy Impact

The oil production of Kuwait, Iraq, Saudi Arabia, and the UAE collectively dropped by at least 10 million barrels per day — the largest supply disruption in the history of the global oil market. Brent Crude surged past $120 per barrel.

Food Security Emergency

GCC states rely on the Strait for over 80% of their caloric intake. By mid-March, 70% of the region's food imports were disrupted, forcing retailers to airlift staples and causing consumer price spikes of 40-120%.

Mass Evacuation

Over 220,000 Indian nationals were evacuated from the GCC region and Iran as the crisis deepened.

The crisis raises questions about the foreseeable humanitarian consequences of the war:

  1. Objects indispensable to civilian survival (Geneva Protocol I, Article 54): The foreseeable disruption of food and energy supplies to civilian populations in the Gulf region.
  2. Right to food (ICESCR Article 11): The 70% disruption in food imports threatens the right to adequate food for millions of people across the Gulf.
  3. Transit passage (UNCLOS Article 38): While Iran bears direct responsibility for the closure, it was triggered by the US-Israeli war.

Why This Grade

Graded Critical, not International Crime (reviewed 2026-10-04). The disruption is a consequence of the war assessed in iran-war-crime-of-aggression; the closure of the strait itself is Iran's act, and no Rome Statute crime is attributed to US conduct in this entry. Its gravity:

  • Global scale: Affects energy and food security for hundreds of millions of people worldwide.
  • Largest supply disruption in history: 10 million barrels/day lost.
  • Food emergency: 70% food import disruption across the Gulf.
  • Foreseeable consequence: The strait closure was a foreseeable result of attacking Iran.
  • Mass displacement: 220,000+ evacuees.

Update: Reopening Collapses, Strait Still Constricted (July–September 2026)

The June memorandum's promise to reopen the strait did not survive the summer. When the ceasefire collapsed in July (see the July 2026 entry), Iran struck two supertankers and the US reimposed its blockade of Iranian ports; Al Jazeera reported that the International Maritime Agency said attacks in the strait "had claimed the lives of two seafarers" (Al Jazeera, July 14). On August 26, Iran announced a temporary 7-mile-wide transit corridor with Oman, with entry and partial exit through Iranian waters, saying full reopening depended on the US meeting its June commitments. Trump asserted US forces had destroyed "all" 28 Iranian mine-laying boats in the strait's international waters, a claim Iran's deputy foreign minister dismissed as "only aimed at calming the markets." Before the war roughly 130 ships crossed the strait daily (Al Jazeera, August 26). In late September, Trump rejected an Iranian proposal under which Iran would reopen the strait after the US lifted the blockade, waived oil sanctions, released frozen assets and observed a regional ceasefire (see the September 2026 entry).

  1. Corrected after ICC-standard legal review: corrected the IEA quote (energy security, not food), replaced the claim that the US struck civilian port cities with CENTCOM's account and Iran's unverified allegation, stated that Iran closed and mined the strait and the US role is the aggression rather than complicity, and marked the Kharg oil slick's source as disputed.

Sequence of events

  1. Strait of Hormuz effectively closes

    Following the start of the US-Israeli war on Iran, the IRGC issues warnings prohibiting vessel passage through the strait. Tanker traffic drops by 70%.

  2. Iran declares complete closure

    Iran's IRGC says 'not one litre of oil' will get through the Strait of Hormuz, declaring complete closure.

  3. 10 million barrels/day lost

    Oil production of Kuwait, Iraq, Saudi Arabia, and the UAE collectively drops by at least 10 million barrels per day.

  4. Food security emergency across Gulf states

    70% of GCC food imports disrupted, causing 40-120% consumer price spikes. Retailers airlift staples to maintain supply.

  5. IEA calls it 'greatest energy security challenge in history'

    The head of the International Energy Agency describes the situation as the 'greatest global energy security challenge in history.'

  6. Trump threatens to 'obliterate' Iran's power plants

    Trump demands Iran open the strait in 48 hours or he will 'obliterate' the country's power plants, escalating the crisis further.

  7. Two-week ceasefire announced; Iran agrees to reopen strait

    Trump announces a two-week ceasefire with Iran. Iran says it will allow safe passage through the Strait of Hormuz if vessels coordinate with Iranian forces. However, by April 9 the strait remains effectively closed — only four dry cargo ships pass through versus the nine-per-day wartime average.

  8. US Navy enters strait for first time since war began

    Trump announces US forces are 'clearing' the Strait. US Navy destroyers enter the strait for the first time since the war began. Iran claims an American vessel turned back after warning and accuses the US of violating the ceasefire.

  9. Islamabad peace talks collapse; Trump declares naval blockade

    After 21 hours of failed negotiations in Islamabad, Trump declares a full naval blockade of all Iranian ports. The blockade targets all vessels entering or departing Iranian waters. Trump says he 'no longer cares about negotiations.'

  10. US naval blockade takes effect

    The naval blockade begins at 10 AM ET. Trump threatens ships approaching the blockade will be 'blown to hell.' A 40-nation coalition led by the UK begins planning to reopen the strait. Iran warns 'no port in the Persian Gulf will be safe.'

  11. Only four ships attempt crossing; all turned back

    BBC Verify analysis of public transponder data showed only four ships attempted to cross the Strait of Hormuz on April 14 — all stopped or reversed course after presumed U.S. interception. Macron and Starmer announced a multilateral meeting on April 17 to coordinate a 'defensive mission' to maintain free passage, underscoring allied opposition to the blockade.

  12. Israel-Lebanon 10-day truce creates opening

    Trump announced Israel and Lebanon agreed to a U.S.-brokered 10-day truce, reducing one front of the regional conflict. The Pentagon confirmed 13 ships had been turned back since the blockade began.

  13. Iran reopens strait for commercial shipping

    Iran announced that commercial vessel passage through the Strait of Hormuz is completely open during the Lebanon truce period. Trump confirmed the development, stating the war was 'very close to over.' The U.S.-Iran ceasefire expires April 23 without a permanent agreement — the global energy and food security crisis triggered by the war remains unresolved.

  14. Iran re-closes Strait of Hormuz

    Iran announced the strait was again closed to most traffic, blaming the U.S. refusal to lift its naval blockade of Iranian ports as a 'breach of trust.' The re-closure reversed the brief April 17 partial opening and renewed the energy and food supply disruption affecting Gulf states and global markets.

  15. U.S. Navy seizes Iranian cargo ship Touska; oil prices surge

    U.S. forces fired on and seized the Iranian-flagged cargo ship Touska in the Gulf of Oman after it attempted to bypass the naval blockade. Iran's Foreign Ministry called the seizure 'extremely dangerous' and 'criminal,' demanded the vessel's immediate release, and vowed retaliation. Oil prices jumped sharply on the news, with markets interpreting the seizure as further imperiling the fragile ceasefire.

  16. Ceasefire deadline April 23; Hormuz reopening the central demand

    The U.S.-Iran ceasefire expires April 23. Full Hormuz reopening remains the core U.S. negotiating demand; Iran insists the naval blockade must be lifted first. Trump has threatened to resume bombing if no deal is reached, saying 'I expect to be bombing.' The global energy and food security crisis triggered by the war remains unresolved with no permanent agreement in sight.

  17. Trump extends ceasefire hours before expiry; IRGC seizes two cargo ships

    Hours before the ceasefire was set to expire, Trump extended it at Pakistan's request to allow time for an Iranian proposal. Within hours, Iran's IRGC seized two container ships and fired on a third, causing serious bridge damage — in direct retaliation for the US seizure of the Iranian vessel Touska three days earlier. By April 22 the US had intercepted 29 ships total since the naval blockade began.

  18. Trump cancels Pakistan peace talks; claims US 'controls' strait

    Trump canceled the US negotiating team's scheduled trip to Pakistan, citing lack of Iranian good faith. Simultaneously he claimed the US 'fully controls' the Strait of Hormuz while acknowledging he is personally keeping it closed to deny Iran its oil revenue — an explicit statement that the strait closure is being weaponized as economic coercion against the Iranian civilian population.

  19. US launches 'Project Freedom'; Iran attacks UAE

    The US launched Operation 'Project Freedom' to assert freedom of navigation for commercial vessels through the strait. On the same day, Iranian forces attacked targets in the UAE — a significant regional escalation beyond the Iran-US bilateral conflict. Oil markets spike on renewed regional uncertainty.

  20. Kharg Island oil spill detected in Copernicus satellite imagery

    Sentinel-1, Sentinel-2, and Sentinel-3 satellite imagery reveals a suspected oil spill covering approximately 71 square kilometers west of Kharg Island — Iran's primary crude export terminal. Analysts estimate roughly 80,000 barrels of crude have leaked from the terminal. Iran denies a spill is occurring. The spill, if confirmed, would be the largest marine oil discharge in the Persian Gulf in decades, threatening marine ecosystems, fisheries, and water desalination infrastructure across the Gulf states.

  21. Iran attacks US destroyers; US strikes military sites at Qeshm and Bandar Abbas

    Iranian forces attack USS Truxton, USS Mason, and USS Rafael Peralta with missiles, drones, and small boats as the destroyers transit the Strait. No US vessels are hit. CENTCOM launches 'self-defense strikes' on what it describes as missile and drone launch sites, command and control locations and ISR nodes on Qeshm Island and at Bandar Abbas. Iran says the strikes hit civilian areas in Qeshm, Bandar Khamir, and Sirik. Each side claims the other fired first. A cargo vessel struck in an overnight US strike catches fire, killing one sailor and injuring ten. Iran declares the ceasefire violated. Trump maintains the ceasefire is still in effect and calls the strikes a 'love tap.'

  22. US fires on Iranian tankers; Iran says US 'crossed point of no return'

    US forces fire on and disable two Iranian oil tankers attempting to evade the naval blockade. Iran's Foreign Ministry says the US has 'crossed the point of no return' and blasts US actions as a 'reckless military adventure in Hormuz.' The Strait continues to be effectively closed, with Iran charging passage tolls of over $1 million per vessel. Washington awaits Iran's formal response to its latest peace proposal.

  23. Iran's reply to peace proposal expected; oil spill reaches 80,000 barrels

    Trump says the US is waiting for Iran's reply to its latest peace proposal, with Trump warning Iran to sign 'fast.' The Kharg Island oil spill is confirmed at approximately 80,000 barrels and growing. Iran's Supreme Leader Mojtaba Khamenei, injured in an earlier blast (kneecap, back, area behind his ear), remains in power. The Strait of Hormuz remains effectively closed on day 70 of the conflict, with the global energy and food crisis unresolved.

    Iran War: Crime of Aggression — War Launched Without Congressional Authorization

    The United States launched a major war against Iran without congressional authorization, without a UN Security Council mandate, and while diplomatic channels remained open. The Brennan Center has called the strikes unconstitutional. International lawyers including Adil Haque and Brian Finucane (Just Security) and UN special procedures have characterized them as a manifest violation of the UN Charter and an act of aggression — what the Nuremberg Tribunal called 'the supreme international crime.'

    Trump's explicit threats to destroy Iran's civilian power infrastructure escalated from 'obliterate' to a promise of 'complete demolition' of every bridge and power plant. Amnesty International characterised them as threats to commit war crimes; no tribunal or UN body has found a threat itself criminal, and a threat is not a listed Rome Statute act.

    U.S. Naval Blockade of Iranian Ports

    The United States imposed a full naval blockade on all Iranian ports after peace talks in Islamabad collapsed, threatening to destroy any vessel approaching. The blockade — the first U.S. naval blockade since the 1962 Cuban Missile Crisis — is a belligerent act that, imposed in furtherance of an unlawful war, is a listed act of aggression (UNGA Res 3314, Art 3(c)). It threatens 25% of global seaborne oil and inflicts severe economic harm on Iran's civilian population; the US declared a humanitarian exemption for food and medicine, and whether that exemption operates in practice is disputed.

    Trump's explicit threats to destroy all civilian infrastructure in Iran — every bridge, every power plant — with the stated goal of ensuring Iran 'could literally never rebuild as a nation again' were characterised by Amnesty International as 'a threat to commit war crimes' and by HRW as threats against objects protected by IHL. Carrying them out would raise war-crime liability under Rome Statute art. 8(2)(b)(ii)/(iv). The threats themselves are prohibited by AP I art. 51(2) if their primary purpose is to terrorise civilians, but they are not a listed Rome Statute crime.

    Trump rejected Iran's peace proposal, called the ceasefire 'on massive life support,' and had a 'very major attack' planned before Gulf allies talked him out of it hours before execution. Congress was not consulted. Vance publicly declared the US 'locked and loaded.' The episode reveals war-making conducted entirely at presidential whim, with no legal or democratic check.
