Iranian state television reported that the Revolutionary Guard Corps Navy said four oil tankers were targeted and set ablaze while transferring oil on Thursday, while three more struck naval mines Wednesday night and were left immobilized. The report gave no details about possible casualties or the flags of the vessels involved, and the broader picture of what actually happened in the narrow waterway overnight remains murky.
The claims, attributed to the Revolutionary Guard Corps Navy, came as the Associated Press reported that the United Kingdom Maritime Trade Operations agency had not corroborated the attacks, even as monitors have noted that some shippers are reluctant to report incidents at all this month. Separately, the UKMTO Centre did verify one tanker interdiction roughly 121 nautical miles east of Duqm, Oman, during what it described as ongoing military activity, according to ABC News. Iranian state-run media also reported that the Revolutionary Guard Corps claimed two oil tankers hit naval mines south of the strait, a separate claim from the overnight tally of seven.
The conflicting accounts fit a pattern. In July, Iran reported that two tankers had exploded and caught fire after entering a minefield in the southern strait, only for U.S. Central Command to reject the account as false, according to gCaptain. In August, CENTCOM said no ships had hit mines in the strait after Iran claimed a supertanker had struck two of them. The same dynamic of dueling claims and incomplete verification appears to be repeating itself this week.
A Deadlier Pattern at Sea
Thursday's reported incidents follow weeks of rising violence in the waterway. A Singapore-flagged container ship, the GFS Pride, sank in the strait after being struck by an unknown projectile, though its 21 crew members were evacuated safely, the BBC reported. It was only the second vessel reported to have sunk during the period, after the Malta-flagged Safeen Prestige went down following an attack near Oman on March 4. One seafarer was killed on Sept. 23 when the bulk carrier Cape Dao was hit by an unknown projectile near Khasab, Oman, striking its bridge and accommodation area.
Twelve vessels reported attacks in and around the strait between Oct. 5 and 11, the highest weekly total UKMTO has recorded since the war began, the BBC reported. The monitoring group JMIC has documented 153 confirmed maritime security incidents across the wider region since March 1, according to gCaptain. As strikes have climbed, the recovery in oil shipments through the strait seen the previous month has slowed, with daily flows falling to about 12.6 million barrels on Oct. 13, down from 15 million at the end of September and a pre-war baseline near 17 million. Traffic through the chokepoint is now running roughly 70% below prewar levels, with only 254 vessel transits recorded in the week ending Oct. 14.
Diplomacy Stalls While Prices Climb
The stakes extend well beyond shipping logs. Around a quarter of the world's seaborne oil trade and about a fifth of global liquefied natural gas supply moved through the Strait of Hormuz in 2025, according to the International Energy Agency. That exposure is already showing up at the pump and on trading floors: Brent crude futures climbed to $111.05 a barrel on Oct. 20, their highest level since May, CNBC reported. The average U.S. gasoline price has reached $4.27 a gallon, nearly $1.30 higher than it was at the start of the war in late February, according to ABC News.
Diplomatically, the path forward looks just as stuck as the oil flow. Washington and Tehran signed a memorandum of understanding in June meant to end the conflict, but the deal fell apart within days, and talks have stalled since, even as the two sides have acknowledged that indirect discussions have continued, per ABC News. Iranian Foreign Minister Abbas Araghchi said Oct. 21 that Tehran remains open to diplomacy but is ready to defend itself. Iran has been promoting a proposal to end the war and fully reopen the strait within a week if the United States meets its conditions, including lifting the blockade of Iranian ports — but President Trump rejected Iran's latest seven-day proposal, and attacks on ships transiting the strait increased afterward.
The Revolutionary Guard Corps Navy has threatened to strike U.S. military bases in the region if Washington keeps helping guide commercial ships through the strait, even as the U.S. says it is enforcing a blockade preventing any Iranian ships from entering or leaving the country while Iran claims control over the strategic waterway. The United States is sending a third aircraft carrier and thousands of additional troops to the region, part of what officials describe as the largest deployment of American warships and aircraft in the Middle East in decades. Mediators are still trying to bring Washington and Tehran back to formal talks, even as Tehran has indicated this month that it could expand its targets to include undersea cables and data centers.
The timing adds political pressure on multiple fronts. Israel is headed toward close elections in which Prime Minister Benjamin Netanyahu could lose power, and the United States holds midterm elections next month amid voter anger over war-linked high prices. A return to all-out war would endanger civilians throughout the region, complicate global deliveries of oil, natural gas and fertilizer, and likely trigger another spike in prices — a risk that remains on the table as U.S.-Israeli attacks on Iran could resume.
