Iran threatens Bab al-Mandeb closure: How would that affect world trade?

An adviser to Supreme Leader Khamenei threatened that Iranian allies could close the Bab al-Mandeb shipping route, similar to Iran's actions in the Strait of Hormuz. This route, connecting the Red Sea to the Gulf of Aden, is vital for global oil trade. Ali Akbar Velayati warned that the U.S. could face disruptions in global energy and trade flow with a single move.
