The Port of Corpus Christi has never been busier as tankers from around the world flock to the U.S. Gulf Coast to load up on crude oil during the Iran war. The Texas port was the third-largest oil export terminal in the world before the war behind Ras Tanura in Saudi Arabia and Basra in Iraq. Its importance has only grown since, as U.S. crude oil exports have surged to a record and the two big Persian Gulf ports are largely cut off from the world due to Iran's blockade of the Strait of Hormuz.
