Iran is cementing its hold over the Strait of Hormuz, demanding vessels give up detailed information and detour into Iranian waters before being vetted by Iran’s Islamic Revolutionary Guards Corps. In some cases, vessels have paid for passage. Traffic through the Strait has fallen by 90% since the start of the war, sending global oil prices skyrocketing and creating alarming shortages in the Asian nations that get their oil from producers in the Persian Gulf. Yet ships with connections to Iran and its chief energy customer, China, continue to transit the Strait.
