US forces struck two Iranian missile launchers on Larak Island in the Strait of Hormuz after Tehran was observed preparing sea-mine rockets, the first US strike on Iran in several weeks. The action revives an oil risk premium just as hopes rose for an Oman-brokered corridor to reopen the strait, while a separate explosion near the island adds to uncertainty over Iran's nuclear talks.
US forces struck two Iranian Revolutionary Guard Corps Navy missile launchers on Larak Island on Sunday after IRGC-N forces were observed preparing to fire rockets fitted with sea mines into the Strait of Hormuz, a US official told Axios. Initial reports describe the action as a drone strike, and unconfirmed local accounts put the toll at two killed and two injured, though Iranian authorities have not confirmed casualty figures.
Strike revives Hormuz risk premium
Larak sits at the narrowest, most heavily militarized stretch of the strait, a chokepoint that before the war carried roughly a fifth of the world's seaborne oil trade. Brent crude had been easing toward the mid-eighties on hopes that Oman-brokered talks might open a temporary shipping corridor, so a strike aimed at preventing fresh mine-laying will likely halt or reverse that slide — reviving the risk premium that has underpinned oil markets since the conflict began in February.
A verified attempt by Iranian forces to seed the strait with mines would itself be bullish for prices independent of the US response, since it threatens the narrow lanes carrier groups have spent months trying to keep clear. Freight and insurance costs for tankers transiting Hormuz remain elevated and are likely to stay that way while incidents like this continue.
Oman's corridor plan meets a fresh setback
Oman, working with Iran, has been drafting a proposal for a temporary shipping route through Hormuz, an effort Qatar has publicly backed as a path back to broader negotiations. US Central Command commander Admiral Brad Cooper said last week that American forces had cleared sea mines from the strait's international shipping lanes and overseen the passage of roughly 1,500 commercial vessels carrying 750 million barrels of crude since the blockade began, while also turning back or disabling vessels attempting to run it. Still, UKMTO logged a tanker struck by an unidentified projectile in the strait last week and rates the risk to vessels transiting Hormuz as severe.
Six months of blockade
The strike extends a campaign that began on June 26, 2026, when US forces targeted more than 80 Iranian military assets in the strait, after Iranian drone attacks hit commercial vessels, including the Singapore-flagged M/V Ever Lovely and the Panama-flagged tanker Kiku. An interim memorandum of understanding signed by Washington and Tehran in mid-June 2026 collapsed within weeks, with each side accusing the other of violating it. By late August, the standoff escalated into a US-enforced blockade under which CENTCOM reported zero tracked Iranian crude oil exports through the strait, a blockade that has also affected allies Bahrain and Kuwait, which rely on the strait to move their own oil and gas.
Iran's Fars news agency separately reported an explosion heard near Larak Island on Sunday, with the cause unstated at the time. Crypto Briefing reports the blast is consistent with a decreased likelihood that Iran agrees to halt uranium enrichment, given Larak's location near the chokepoint and its role in Iranian maritime surveillance.
