Iran declares Strait of Hormuz 'closed' over MOU 'breach'

Summary

Iran’s military has declared the Strait of Hormuz “closed,” citing air strikes in Lebanon as "America's blatant breach" of the Memorandum of Understanding to end the war, Iran's semi-official Tasnim news agency reported—even as politicians on both sides insisted the key shipping lane was open. "The Strait of Hormuz will be closed to vessel traffic," a message attributed to the Iranian military's operation command and posted on Tasnim's Telegram account said about 9:10 a.m. ET The claim directly contradicts comments made just hours earlier by Iran’s foreign ministry, which told Tasnim that shipping through the strait was “operating normally” and denied any closure. U.S. Vice President JD Vance told Fox News in a live interview about 9:30 a.m that “the straits really are open,” pointing to ongoing efforts to keep shipping lanes clear. Tasnim is a semi‑official Iranian news agency associated with the country’s Islamic Revolutionary Guard Corps, meaning its reporting often reflects military or hardline positions rather than unified government policy. The conflicting signals add fresh uncertainty to the status of one of the world’s most important oil chokepoints, through which roughly one‑fifth of global energy supplies pass under normal conditions. This is a breaking news story. More to follow.

Goldman Sachs has projected Brent crude averaging $80 per barrel in the fourth quarter and $75 in the following year, conditional on reduced Middle East tensions, while noting upside risks from potential shipping disruptions in the Strait of Hormuz or Red Sea.

Brent prices rose above $91 per barrel amid recent U.S.-Iran exchanges and Houthi threats to Saudi shipments before edging lower on Tuesday. A senior Iranian official told Reuters that mediators had proposed a 10-day ceasefire to preserve an interim agreement.

US forces struck the tanker Settebello in the Gulf of Oman on June 10, killing three Indian crew members when munitions hit the engine room and adjacent areas. Maritime tracking data indicate the vessel had transported Iranian oil under US sanctions for several years and conducted offshore transfers prior to the strike.

The US military described the action as a precision operation, while reports note the ship was stationary at the time.
