The brief opening for legal trade in Iranian oil is closing.
On 7 July the US Treasury's Office of Foreign Assets Control issued General License X1, revoking the authorisation it had granted just over two weeks earlier. That earlier licence — General License X, issued 21 June under the US-Iran memorandum of understanding — had temporarily permitted transactions in Iranian-origin crude oil, petrochemicals and petroleum products that are otherwise sanctioned.
GL X1 allows only a short wind-down: activity "ordinarily incident and necessary" to closing out permitted transactions, running to 12:01am Eastern on 17 July. After that, no entity is authorised to enter new dealings in Iranian oil, including purchasing or loading cargoes. Any payments to blocked persons made during the wind-down must go into blocked, interest-bearing US accounts.
Treasury tied the reversal directly to the renewed conflict — the strikes on tankers near Hormuz and the collapse of the truce.
The operator relevance is real for anyone in the maritime-security and risk chain around Gulf energy. Firms supporting tanker movements, charterers, traders and their advisers face a hard cut-off on Friday. Compliance teams should assume heightened scrutiny of any Iran-linked cargo, tighten vessel and counterparty screening, and treat sanctions exposure as a live operational risk alongside the physical threat in the strait. The two are now moving together.
