IRGC Maintains Control of Hormuz Corridor as Ceasefire Fails to Reopen Strait

Maritime intelligence tracking shows the U.S.-Iran ceasefire has not reopened the Strait of Hormuz. All April 7-8 transits remained confined to an IRGC-controlled northern corridor at Larak Island, with Iran requiring armed forces coordination for passage. Inbound traffic consisted exclusively of sanctioned, Iranian-trading tankers. The IRGC struck the container vessel Qingdao Star with a Qadir cruise missile on April 7, claiming it was an Israeli ship. Roughly 3,200 vessels including nearly 800 tankers remain stranded west of the strait. Transit conditions, toll arrangements, and the legal framework for passage remain undefined.
The distinction between ceasefire and reopened strait is critical. Iran has conceded nothing operationally at Hormuz; vessel transits require IRGC coordination, and the Qingdao Star strike during the ceasefire demonstrates willingness to use force against commercial shipping. The 3,200 stranded vessels represent persistent leverage regardless of negotiation outcomes. The IRGC's northern corridor at Larak Island functions as a de facto toll operation.
