Iran Seizes Cargo Ships in Strait of Hormuz as US Warns of Six-Month Mine Clearance
Iran's Islamic Revolutionary Guard Corps has seized two cargo ships in the Strait of Hormuz, diverting them to the Iranian coast with their multinational crews detained, as the United States warned that clearing the critical waterway of mines could take up to six months.
The seizures of the MSC Francesca and the Epaminondas on 23-24 April 2026 sent oil prices surging, with Brent crude climbing above $103 per barrel as markets priced in the risk of prolonged disruption to global energy supplies.
Background
The Strait of Hormuz is one of the world's most strategically important waterways, through which approximately 20% of global oil supplies pass. Iran has long threatened to close the strait in the event of conflict, and the ongoing war with Israel and the United States has brought those threats closer to reality.
Key Developments
The crews of the seized vessels included Montenegrin, Croatian, Ukrainian, and Filipino nationals. Iranian state media released footage of commandos boarding a vessel in the strait, while its air defence systems reportedly engaged what were described as "hostile targets." Iran also offered a fee exemption for transit through the strait to "friendly" countries, including Russia, while developing plans to levy tariffs on other shipping.
President Trump issued an order for the US Navy to "shoot and kill" any Iranian small boats observed deploying mines in the strait. The US also seized a tanker suspected of smuggling Iranian oil and announced it would not renew a short-term authorisation permitting the sale of Iranian oil stranded at sea. The US Treasury Secretary warned that sanctions would be imposed on any country found to be purchasing Iranian oil.
Goldman Sachs estimated that approximately 14.5 million barrels per day of Gulf crude output — around 57% of pre-war supply — were offline in April due to precautionary production shutdowns. The warning that mine clearance could take up to six months further solidified concerns about prolonged supply disruption.
Why It Matters
Disruption to the Strait of Hormuz has immediate and severe consequences for global energy markets, driving up oil and gas prices worldwide. For the UK, which imports significant quantities of energy, sustained high prices feed directly into inflation and household energy bills.
What's Next
The US Navy is conducting operations in the region to protect international shipping. Diplomatic efforts to resolve the standoff are ongoing, but a swift resolution appears unlikely given the depth of the conflict. More at The Hindu.
