U.S. revokes Iran oil sales authorization after tanker attacks | 7 July 2026 | The U.S. Treasury Department on Tuesday revoked its authorization of Iranian oil sales after a series of attacks on tankers in the Strait of Hormuz this week. “Iran will only reap benefits if they exhibit good behavior,” a U.S. official told CNBC, speaking on condition of anonymity. “Iran’s actions in the Strait were wholly unacceptable to the United States and will be met with consequences.” A liquefied natural gas tanker, an oil supertanker and an unspecified third tanker came under attack in or near Hormuz on Tuesday, according to the Joint Maritime Information Center, a naval group led by the U.S. that provides security updates to merchant vessels in the Middle East. The threat to ships crossing Hormuz has increased to “severe” as hostile action by Iran is likely, the center warned mariners in a notice.
