OFAC revoked Iran General License X, effective July 7, 2026, and replaced it in full with General License X1, according to the license text posted on Treasury's website OFAC. The revocation and supersession happened the same day it took effect, giving market participants essentially no runway to adjust before the new terms applied.

General License X had authorized the production, delivery and sale of Iranian crude oil, petrochemical products and petroleum products. It was issued on June 21 or 22, 2026 — OFAC's own recent-actions page dates it June 22 — as a temporary, 60-day authorization Reuters. Structured with a hard expiry rather than an open-ended waiver, GL X was always going to require either lapse, renewal, or replacement inside two months. It got replaced instead, and roughly two weeks ahead of its natural sunset.

The context matters for anyone pricing counterparty risk on Iranian-linked crude flows. GL X was issued amid talks toward a final peace deal involving Iran Reuters, and it followed a period of unusually active OFAC intervention in the Iran sanctions program through the first half of 2026. In March, Treasury Secretary Scott Bessent said the U.S. might soon lift sanctions on Iranian oil stranded aboard tankers at sea Reuters. A day later, OFAC issued a 30-day waiver permitting the purchase of that seaborne oil, explicitly framed as an effort to ease crude prices Reuters. That waiver was allowed to lapse in mid-April without renewal Reuters. Two months later, GL X arrived as a broader authorization covering production and sale, not merely stranded cargoes — before itself being swapped out for X1 within roughly two weeks of issuance.

This oscillation — waiver, lapse, broader license, rapid supersession — sits awkwardly against Treasury's parallel enforcement posture. In December 2025, Treasury announced it was intensifying OFAC actions against Iran's sanctions-evading shadow fleet, the loosely tracked tanker network used to move Iranian petroleum outside formal channels Treasury. Separately, in July 2025, OFAC had issued Iran General License R, authorizing what was described as limited safety-related activity OFAC — a narrower carve-out than either GL X or X1, and one that predates the current negotiating cycle by nearly a year.

Taken together, the sequence reads less like a single policy pivot than a series of tactical adjustments tied to negotiating leverage. A shadow-fleet crackdown announced in December sits alongside a safety-focused general license from mid-2025, a seaborne-oil waiver in March 2026 that was deliberately let expire in April, and now a full production-and-sale license issued in June that lasted barely two weeks before being revoked and rewritten. For desks running Iran-exposure compliance screens, the operative fact is that GL X no longer exists as a valid authorization; any transaction structured under its terms after July 7, 2026 needs to be re-checked against GL X1's specific conditions, which have not yet been detailed publicly beyond the fact of full supersession.

The rapid churn also raises the practical question of how license architecture is being used as a diplomatic instrument rather than a stable compliance framework. Temporary, capped-duration licenses — 30 days for the seaborne waiver, 60 days for GL X — give Treasury room to signal flexibility toward Tehran during active talks while retaining the ability to reverse course quickly if negotiations stall. That optionality is valuable to policymakers. It is considerably less convenient for banks, trading houses, insurers and freight operators trying to build compliance procedures around a moving target, especially when a license is revoked and replaced same-day rather than allowed to run to its stated expiry.

None of the sources reviewed specify the substantive differences between GL X and GL X1's authorized activities, only that X1 supersedes X "in its entirety" as of July 7, 2026. Firms with exposure to Iranian petroleum flows will need the full X1 text to determine whether the scope of permitted production, delivery and sale activity has narrowed, widened, or simply been re-papered with adjusted conditions and expiry terms.
