Iran said it has fully closed the Bab al-Mandab Strait after Israeli strikes, framing the move around one of the world’s most important maritime chokepoints. The passage carries about 12% of global trade, so any disruption or credible threat to transit could quickly ripple through shipping routes, freight costs, energy markets and broader risk sentiment. The claim points to a potentially major escalation because Bab al-Mandab links the Red Sea to the Gulf of Aden, making it a critical corridor for vessels moving between Europe and Asia.
