The World's Most Important Waterway Is a War Zone

One Corridor. No Alternatives.

Pull up a map of the Persian Gulf and find the narrow gap where it meets the Gulf of Oman. That gap is 33 kilometres wide at its tightest point. Through that gap flows roughly 20 million barrels of oil every single day, around 25 percent of the world's entire seaborne supply. Twenty percent of global liquefied natural gas goes through there too. In 2024, 84 percent of all crude shipments from the Gulf states went through Hormuz. China got one third of its oil via this corridor. Europe got 12 to 14 percent of its LNG from Qatar, also through this corridor.

There is no bypass. The Saudi East-West Pipeline exists, but it can handle a fraction of Hormuz volumes. The infrastructure, the tanker fleets, the port logistics of the entire Gulf region were all built around one assumption: Hormuz stays open. The moment that assumption broke, everything downstream broke with it.

How It Started: February 28, 2026

The US and Israel launched Operation Epic Fury in the early hours of February 28. The operation targeted Iranian military and nuclear facilities across the country. In the opening hours, Supreme Leader Ali Khamenei was killed. Iran's government called it an assassination. Washington called it a military strike on a command and control target. The naming debate is still ongoing. What is not in dispute is what happened next.

Iran launched retaliatory missile and drone attacks on US military bases in the Gulf, on Israeli cities, and on allied Gulf state infrastructure. The Islamic Revolutionary Guard Corps issued a formal closure of the Strait of Hormuz to commercial traffic, threatening any vessel attempting to transit. Within 48 hours, ship traffic through the strait had dropped to near zero. Over 150 ships anchored offshore, waiting. More than 2,000 vessels and 20,000 mariners became stranded inside the Persian Gulf with nowhere to go.

51 Days of Attacks: The Ship-by-Ship Record

What followed was the most sustained campaign of commercial shipping attacks since World War Two. Windward AI, which tracks vessel movements and incidents in real time, confirmed 68 maritime incidents between March 1 and April 22. That breaks down to 31 commercial vessels directly attacked or damaged and 37 offshore oil, gas, and port facilities struck.

The weapons used were not primitive. The IRGC deployed ballistic missiles, loitering munitions, unmanned surface vehicles packed with explosives, and conventional projectiles fired from fast boats. They also laid naval mines in key transit corridors, a fact confirmed by US intelligence on March 10.

Total confirmed casualties as of April 22: at least 12 seafarers killed or missing. One tugboat sunk. At least 16 merchant ships damaged. Seven abandoned at sea.

The Economic Fallout: Real Numbers

Oil markets reacted fast. Brent crude crossed $100 per barrel within days of the closure, something that had not happened in four years. By mid-March it was trading at $126. Dubai crude, the benchmark for Gulf exports, peaked at $166 per barrel during the worst of the fighting. (Both benchmarks fluctuate daily and move sharply on ceasefire news, so check current pricing before citing these figures in any financial context.)

The supply cuts were immediate and severe. Iraq's oil output fell from 4.3 million barrels a day to 1.3 million by March 8. Saudi Arabia cut production by 20 percent. Qatar declared force majeure on March 4, suspending its contractual obligations to LNG buyers. Kuwait followed with its own force majeure declaration on March 7. Across the Gulf, over 10 million barrels a day of production was effectively offline by mid-March.

The ripple effects hit commodities most people had never connected to oil shipping. Fertilizer prices jumped 50 percent because one third of the world's urea exports move through or near Hormuz. Aluminum ticked higher. Helium distributors began rationing. Natural gas prices in Europe nearly doubled from 30 to 60 euros per megawatt-hour at peak.

The Touska Incident: April 19

After an initial ceasefire agreed on April 8 collapsed over disagreements about Lebanon and Hormuz control, Trump announced a full US naval blockade on Iranian ports starting April 13. The rationale from Washington was that the blockade would pressure Tehran into returning to nuclear talks. Iran called it an act of war.

On April 19, an Iranian-flagged cargo ship called the Touska attempted to move through the blockade near Hormuz. The USS Spruance, a US Navy destroyer, fired multiple rounds from its 5-inch deck gun after the vessel refused to comply with orders to halt. The Touska was boarded and seized.

The significance of the gunfire was not lost on military observers. It was the first time a US Navy surface vessel had fired its deck gun in a live combat engagement in nearly four decades. Iran's foreign minister Abbas Araghchi described the seizure as "an act of piracy on the high seas." Tehran pulled its negotiators out of the Islamabad peace talks hours later.

Today: Ceasefire in Name Only

On April 21, Trump announced he was extending the ceasefire indefinitely. He framed this as goodwill. The naval blockade on Iranian ports, however, remains in place. This morning, Iran's IRGC responded by seizing three vessels crossing the strait: the Epaminondas, the MSC Francesca, and the Euphoria.

Vice President Vance paused his diplomatic trip to Pakistan to deal with the fallout. Lufthansa announced it is cancelling 20,000 flights, citing the ongoing war risk to airspace over the region. Trump's own officials have reportedly been whispering privately that his Truth Social posts about Iran risk derailing any chance of a deal.

The core gap between the two sides has not closed. The US wants a complete shutdown of Iran's nuclear programme, limits on its missile capabilities, and a reduction in its support for regional allies including Hezbollah and Hamas. Iran insists on its right to enrich uranium domestically for civilian use, refuses to surrender its existing stockpiles of highly enriched uranium, and will not use its military capabilities as a bargaining chip.

Neither side is moving. The ships are still being seized. The blockade is still running. And the ceasefire is being extended while both parties escalate.

Historical Pattern Worth Knowing

This is not the first time Hormuz has been weaponised. In 1988, during the tanker war phase of the Iran-Iraq conflict, the US Navy fought a one-day battle against Iranian forces called Operation Praying Mantis after Iran mined international shipping lanes. The US sank two Iranian frigates and several smaller vessels. Iran backed down, but only after the US demonstrated it was willing to use force at scale.

In 2019, following Trump's withdrawal from the 2015 nuclear agreement, Iran seized a British tanker and shot down a US surveillance drone near the strait. That episode resolved without major military confrontation. The 2026 crisis is categorically different in scale. The 68 confirmed incidents, the 12 dead, and the weeks of near-total closure have no peacetime precedent.
