#美终止对伊朗石油制裁豁免

On July 7, 2026, the U.S. Treasury Department's Office of Foreign Assets Control (OFAC) issued an announcement revoking "General License X," which had been in effect for only 16 days and originally allowed Iran to resume oil exports within 60 days. The newly issued "General License X1" immediately banned all new Iranian oil transactions, permitting only the completion of already-initiated wind-down activities by July 17.

This event epitomizes the dramatic turn in U.S.-Iran relations. Just two weeks earlier (June 21), as a core concession of the U.S.-Iran "Islamabad Memorandum of Understanding," the U.S. had lifted oil sanctions on Iran. Now, this brief "economic breather" has been swiftly rescinded.

The official reason given by the U.S. is that Iran attacked three commercial vessels in the Strait of Hormuz. The United Kingdom Maritime Trade Operations (UKMTO) reported that three oil tankers were attacked by drones and other weapons in the area within 24 hours.

The U.S. stated that Iran's actions were "completely unacceptable" and "a clear violation of the ceasefire agreement," and subsequently used this as a pretext to launch retaliatory military strikes.

This exemption was itself a product of the "fight and negotiate" model between the U.S. and Iran.

- June 18: The two sides signed the "Islamabad Memorandum of Understanding," exchanging a 60-day ceasefire for the U.S. lifting oil sanctions on Iran.
- June 21: The U.S. issued "General License X," exempting Iranian oil exports.
- July 7: The U.S. revoked the exemption and launched military strikes, citing the tanker attacks.

Experts had previously warned that the U.S.-Iran contradictions were "deep-seated and hard to resolve," and resolving all issues within 60 days was unrealistic, with negotiations prone to reversal.

Reactions and Chain Effects

- Market Turmoil: International oil prices surged sharply. Brent crude broke through $75 per barrel, WTI crude rose to about $72, with intraday gains exceeding 5%.
- Iran's Protest: Condemned the U.S. for "seriously violating" Article 10 of the memorandum of understanding and warned of taking all necessary measures to defend national interests.
- Agreement Endangered: Sanctions consultancy experts pointed out that this move "may signal the end of this memorandum of understanding."
- Allies' Condemnation: Saudi Arabia, Qatar, and others condemned the attacks, stating they threaten international navigation and global energy supply security.

This is not merely a policy reversal, but a high-stakes political gamble that could have profound consequences:

1. **Bankruptcy of the "Pay-for-Performance" Logic**: U.S. officials claimed Iran needed to "behave well" to benefit. Yet withdrawing the promise in just 16 days sends a dangerous signal to the world: agreements with the U.S. can be voided at any time based on unilateral determinations, severely undermining U.S. credibility as a negotiating partner in the future.
2. **Missed Diplomatic Window and Escalated Military Confrontation**: The exemption was a diplomatic "carrot," while its revocation brought back the "stick." Along with the revocation, the U.S. military launched strikes against over 80 targets in Iran. Hardliners in Iran have called for "no cards left to play except closing the Strait of Hormuz." This could push the situation from "manageable conflict" to "full-scale confrontation."
3. **Hostage of Global Economy and Energy Security**: The Strait of Hormuz is the world's most critical oil transit chokepoint. Some analysts criticize this move as "strategic self-harm." If tensions lead to a blockade or frequent attacks in the strait, global oil prices could spike again, endangering the recovering global economy.
4. **Erosion of Trust Among Regional Allies**: While regional allies like Saudi Arabia and Qatar condemned Iran, the U.S.'s volatile policy also raises doubts about the reliability of future U.S. security commitments.

The U.S. termination of the exemption for Iranian oil sanctions appears to be a strong response to an attack, but in reality, it reflects the deep predicament of U.S.-Iran relations. With one short-term gamble, it has risked the credibility of diplomatic agreements, regional stability, and even the security of the global economy. Within the "fight and negotiate" framework, this exemption, which survived only 16 days, may signal the beginning of an even more turbulent period.
