US reinstates sanctions on Iranian oil sales after LNG, oil tanker attacks

The United States has re-imposed sanctions on Iranian oil, ending an earlier exemption that had allowed Iran to continue oil sales until August 21. The exemption will now end on July 17, following reports that three commercial vessels were attacked in and near the Strait of Hormuz.

A U.S. official said the attacks were “wholly unacceptable” and warned that there would be consequences. Another U.S. official said initial evidence suggests Iran fired at the three vessels, although Iran has not commented or accepted responsibility.

Despite the renewed sanctions, U.S. officials said negotiations with Iran are continuing in hopes of reaching a broader agreement. However, the latest attacks have increased tensions and could undermine the fragile diplomatic progress.

The news caused oil prices to rise by more than 5%, reflecting concerns about possible disruptions to the Strait of Hormuz, through which about 20% of the world’s oil and liquefied natural gas shipments normally pass. Any prolonged disruption could increase global energy prices.

Iran relies heavily on oil exports—especially sales to China—for government revenue, so the renewed sanctions are expected to put additional pressure on its economy. Energy analysts also warned that the recent attacks suggest the ceasefire between the U.S. and Iran may be less stable than markets had assumed, increasing the risk of further oil price volatility.
