Iran has shut down the Bab al-Mandab Strait, a critical maritime corridor connecting the Red Sea to the Gulf of Aden, in response to Israeli military strikes. The closure, announced by Iranian authorities, immediately raised concerns about disruptions to global oil shipments and trade routes that rely on this narrow passage.
A key maritime chokepoint
The Bab al-Mandab Strait is one of the world's most vital shipping lanes. About 7 million barrels of oil pass through it daily, along with container cargo linking Asia, Europe, and Africa. By closing the strait, Iran effectively blocks the shortest sea route between the Indian Ocean and the Mediterranean, forcing vessels to take the much longer journey around the Cape of Good Hope.
Immediate effects on shipping
Tankers and cargo ships already in the area faced sudden delays. Some rerouted within hours, adding weeks to transit times and pushing up freight costs. Insurance premiums for vessels operating near the strait are expected to rise sharply. The move also threatens to spike energy prices if the closure lasts more than a few days.
Unanswered questions
It remains unclear how long Iran will enforce the shutdown or under what conditions it might reopen the strait. The Israeli strikes that triggered the closure were not detailed by either government. Without a clear timeline, shipping companies and oil markets are bracing for extended disruption.
