Iran has declared the Strait of Hormuz “completely open” to commercial shipping during a fragile ceasefire in the Middle East, in a move that has sharply eased tensions over one of the world’s most strategically vital maritime chokepoints.
Foreign minister Abbas Araghchi announced on Friday that all commercial vessels would be permitted to pass through the narrow waterway, which links the Persian Gulf to the Gulf of Oman and carries around a fifth of global oil trade. The decision, he said, applies for the duration of the current ceasefire and follows what Tehran described as “coordinated maritime arrangements” established by Iran’s Ports and Maritime Organisation.

The announcement comes after weeks of disruption in the region linked to the wider Iran–US–Israel conflict, which had severely restricted shipping through the strait. Maritime traffic had been drastically reduced during the escalation, with insurers warning of extreme risk and several major shipping firms diverting routes away from the Gulf altogether.
In his statement posted on X, Araghchi said the reopening was intended to ensure “uninterrupted passage for all commercial vessels” during the ceasefire period, signalling what analysts interpret as a cautious attempt by Tehran to stabilise global energy flows while maintaining strategic leverage.

The simultaneous messages underline the fragile and conditional nature of the current ceasefire, which was brokered earlier this month amid intense diplomatic pressure and fears of a wider regional war. The truce, involving the United States, Iran and Israel in various indirect arrangements, has been repeatedly tested by sporadic strikes, political rhetoric and unresolved disputes over security guarantees in the Gulf.
The Strait of Hormuz has long been considered one of the world’s most dangerous maritime flashpoints. Narrow and heavily trafficked, it handles crude oil exports from Saudi Arabia, Iraq, the United Arab Emirates and Kuwait, making it indispensable to global energy markets. Any disruption can send immediate shockwaves through oil prices and global supply chains.
Indeed, markets reacted swiftly to Tehran’s announcement. Oil prices fell sharply on Friday, with Brent crude dropping by more than 10% as traders priced in reduced risk to supply routes and a possible easing of geopolitical tensions. Analysts said the decline reflected renewed optimism that diplomatic efforts could prevent a full-scale regional escalation.
However, uncertainty remains over how “open” the strait truly is in practice. Iranian officials have indicated that while commercial shipping is permitted, vessels must follow designated routes and may still require approval from the Islamic Revolutionary Guard Corps Navy in certain circumstances. This has led some maritime experts to caution that the reopening may be more conditional than absolute.
The wider geopolitical context also remains volatile. While the ceasefire has temporarily reduced hostilities, underlying tensions between Iran and Israel remain unresolved, and US–Iran negotiations over security arrangements in the Gulf are still ongoing.
Diplomats warn that the situation could quickly reverse if any party interprets ceasefire violations differently, particularly in relation to attacks in Lebanon and Syria, which have been linked to the broader regional conflict.
