U.S. revokes Iran oil license after tankers struck near Strait of Hormuz

The United States revoked a general license on Tuesday that had permitted Iranian oil sales, escalating tensions after three tankers were struck by unidentified projectiles near the Strait of Hormuz in recent days.
The Treasury Department’s Office of Foreign Assets Control announced the move, citing Iran’s actions in the strategic waterway as “wholly unacceptable” and vowing consequences. The revocation follows attacks on a Qatari liquefied natural gas tanker, a Saudi crude tanker, and a vessel under the Marshall Islands flag, all within 48 hours. Iran has neither commented on the incidents nor claimed responsibility, though U.S. officials allege the Islamic Revolutionary Guard Corps was responsible.
Oil prices surged more than 5% following the announcement, reflecting market unease over the fragile ceasefire between Washington and Tehran. The U.S. and Iran had agreed in late June to reopen the Strait of Hormuz—through which one-fifth of the world’s oil transits—after a three-month conflict throttled global energy supplies. Traffic through the strait remains at one-third to one-fifth of pre-war levels, despite the easing of restrictions.
The revoked license, issued on June 21 as part of a memorandum of understanding, had allowed Iran to sell oil in exchange for commitments to stabilize the strait. The Treasury granted a wind-down period until July 17 for existing transactions. “Iran will only reap benefits if they exhibit good behavior,” a U.S. official told Reuters . Negotiators are still working toward a final agreement, though the latest escalation threatens to derail talks.
The U.S. Navy-led Joint Maritime Information Center raised the threat level for strait transit to “severe” on Tuesday, the highest since June 15, citing deliberate hostile action. The Islamic Revolutionary Guard Corps has intensified hailing of vessels and deployed additional naval assets, according to the center’s advisory.
Qatar summoned Iran’s vice ambassador on Tuesday to protest the attack on its LNG tanker, while Saudi Arabia condemned the strikes on its crude carrier. The incidents have disrupted a fragile diplomatic détente, with Iran accusing regional states of “tampering” with shipping routes and warning of risks to uncoordinated vessels.
The U.S. military responded by striking more than 80 targets in Iran on Tuesday, including air defense systems, anti-ship missiles, and Revolutionary Guard boats, according to U.S. Central Command. President Donald Trump approved the strikes from the NATO summit in Ankara, the *New York Times* reported .
Analysts warn the escalation could trigger further retaliation, undermining the fragile peace and risking a renewed disruption to global energy markets. The Strait of Hormuz remains a critical chokepoint, and any prolonged instability would send shockwaves through oil and gas supplies.
