WASHINGTON — The Biden administration on Tuesday abruptly revoked a temporary sanctions waiver that had allowed Iran to export crude oil and petrochemical products, declaring that a recent string of Iranian attacks on commercial vessels in the strategic Strait of Hormuz was “wholly unacceptable.”
The move by the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) effectively ends a brief diplomatic window that began in mid-June under a temporary Memorandum of Understanding (MoU) between Washington and Tehran.
The Treasury Department gave international companies until July 17 to wind down all transactions involving Iranian oil, gas, and petrochemicals.
”Iran’s actions in the Strait were wholly unacceptable to the United States and will be met with consequences,” a senior U.S. official said, speaking on the condition of anonymity to discuss sensitive negotiations.
The official emphasized that the initial relief granted to Tehran was “entirely performance-based,” adding, “Iran will only reap benefits if they exhibit good behavior.”
The abrupt shift came after maritime monitors reported that at least three commercial tankers—including a Qatari liquefied natural gas (LNG) vessel—were struck by missiles and explosive drones within a matter of hours while transiting the Strait of Hormuz.
The strikes mark a sharp escalation in a region that has been plagued by a wider conflict involving the U.S., Israel, and Iran.
Global oil prices surged by more than 5 percent immediately following the Treasury Department’s announcement, reflecting deep anxieties across energy markets over a renewed disruption to the world’s most critical maritime chokepoint.
The sudden snapping back of sanctions threatens to derail a fragile ceasefire that had temporarily halted a highly volatile conflict between Washington and Tehran.
The crisis initially erupted when a full-scale regional conflict began, prompting the United States to enforce a strict naval blockade on Iranian ports. In retaliation, Iran blocked the Strait of Hormuz, a narrow waterway between Oman and Iran through which roughly 20 percent of the world’s petroleum and liquefied natural gas flows.
The mutual economic stranglehold was partially eased in mid-June after both sides signed a 14-point tentative MoU. Under those temporary terms, the U.S. removed its naval blockade and issued General License X to allow Iranian crude production to rebound, while Iran agreed to reopen the Strait to international shipping.
However, intelligence and maritime security experts report that Iran has recently sought to exert aggressive control over the waterway, allegedly demanding illicit “toll” payments from commercial ships for safe passage and trying to force vessels into Iranian-approved transit routes.
The targeted strike on the Qatari LNG vessel Al Rekayyat significantly raised the stakes, drawing a sharp condemnation from Doha, which has frequently served as a key peace mediator between Western powers and Iran.
Despite the breakdown of the oil waiver, U.S. officials maintained on Tuesday that diplomatic tracks are not entirely dead. “Our negotiators continue to work in good faith towards a final deal,” the U.S. official stated.
Nevertheless, geopolitical analysts warn that by stripping Iran of its primary economic incentive, Washington may inadvertently trigger an even more aggressive response from Tehran.
With its oil revenues frozen once more, Iran may double down on asymmetric warfare in the Gulf, drastically escalating the risk of a direct military confrontation in the days ahead.
