The US Treasury Department, through its Office of Foreign Assets Control (OFAC), revokes a general licence that authorised certain sales of Iranian oil to the United States. OFAC states that effective July 7, 2026, General License X, issued June 21, 2026, is revoked and replaced in full by General License X1. The previous licensing framework followed a partial sanctions lift related to Iranian oil exports, implemented after the US described “encouraging” talks over ending the war. In June, the Treasury issued a 60-day sanctions waiver to allow production, delivery and sale of Iranian oil to the US. Multiple outlets report that the revocation follows an escalation of incidents in the Strait of Hormuz, where three tankers are said to have been hit in and near the shipping route in the past 24 hours or in recent days. Reuters reports US officials describe Iran’s actions in the Strait of Hormuz as “wholly unacceptable,” warning that consequences will follow. One outlet specifically mentions three British tankers being struck. The reported attacks and ensuing tensions are cited as the immediate context for the US decision.
