An Iranian Revolutionary Guards senior official said on Monday (March 2, 2026) that the Strait of Hormuz is closed and Iran will fire on any ship trying to pass, Iranian media reported.
This is Iran’s most explicit warning since telling ships that it was closing the export route on Saturday (February 28, 2026), a move that threatens to choke a fifth of global oil flows and send crude prices sharply higher.
“The strait (of Hormuz) is closed. If anyone tries to pass, the heroes of the Revolutionary Guards and the regular navy will set those ships ablaze,” Ebrahim Jabari, a senior adviser to the Guards commander-in-chief, said in remarks carried by state media.
The strait is the world’s most vital oil export route, which connects the biggest Gulf oil producers, such as Saudi Arabia, Iran, Iraq and the United Arab Emirates, with the Gulf of Oman and the Arabian Sea.
The closure was triggered by U.S. and Israeli strikes on Iran on February 28 seeking to topple its leaders, with U.S. President Donald Trump offering Iranians help in ousting the ruling clerics.
In response, Iran fired several barrages of missiles at its Gulf neighbours hosting U.S. military bases such as Qatar, Kuwait and Bahrain. Tehran also fired missiles at the United Arab Emirates, Saudi Arabia and Oman.
About 20% of the world’s daily oil consumption passes through the Strait of Hormuz, which is about 33 kilometers (21 miles) wide at its narrowest point.
Oil markets have focused on tensions between Tehran and its old foes, the U.S. and Israel, fearing that a full-blown conflict would disrupt supplies and destabilise the region.
The move also comes after global shipping had already experienced disruptions linked to drone and missile attacks carried out by Yemen’s Iran-aligned Houthi militants. The group has targeted vessels in the Red Sea and the Gulf of Aden since the war on Gaza broke out in 2023.
