Iran has blacklisted 45 vessels for allegedly violating rules for traversing the Strait of Hormuz, a move that prompted three Indian refining companies and a global energy major to cease using them. The action, announced Sunday, is a response to U.S. sanctions targeting Tehran.
According to Reuters, the blacklisted ships are involved in shuttling oil out of the Persian Gulf to larger tankers for export. Iran's Persian Gulf Strait Authority warned that any caught vessels could face fines, detention, and cargo confiscation.
The announcement preceded new U.S. Treasury sanctions unveiled Monday, which target brokers, companies, and vessels across several countries involved in transporting Iranian oil and channeling revenues to Iranian entities, including the Islamic Revolutionary Guard Corps.
Concerns are rising that the Strait of Hormuz, a critical chokepoint for global oil supply, could face further paralysis as the U.S. tightens sanctions on Iran-related tankers and Iran retaliates by targeting vessels from other nations.
