Iran's Islamic Revolutionary Guard Corps struck the Singaporean-flagged container ship Ever Lovely with an unknown projectile southeast of Dahit, Oman, causing damage to the vessel's bridge but leaving all crew members unharmed, according to the U.K. Maritime Trade Operations Centre. The ship continued on its way following the strike, but the attack immediately reignited concerns about the fragility of the diplomatic progress made earlier this week at Switzerland's Burgenstock resort, where U.S. Vice President JD Vance and Iranian parliament Speaker Mohammad Bagher Ghalibaf agreed on a 60-day roadmap toward a final peace deal.
The attack had immediate consequences for maritime operations in the region. The International Maritime Organization had been coordinating a plan to evacuate approximately 11,000 sailors who have been stranded in the Strait of Hormuz area throughout the conflict, but paused those operations following the Ever Lovely incident. Three oil tankers that had been on course to transit the strait via a southern Omani coastal route — designated by the United States as the approved passage — turned back after the IRGC issued warnings. Three additional vessels diverted course. The IRGC insisted that all ships must use a northern route designated by Iranian authorities and coordinated with the Persian Gulf Strait Authority, the Iranian body established to manage maritime transit through the waterway.
The Persian Gulf Strait Authority stated after the attack that 'any passage through routes outside the framework designated by PGSA will not be covered by safe passage guarantees and will not be entitled to insurance coverage or related liabilities.' The statement suggests that despite high-level diplomatic progress at the political level, the IRGC is actively asserting operational control over the strait in a manner that directly complicates the implementation of any framework agreed in Switzerland. The divergence between the U.S.-backed Omani coastal route and the Iranian-designated northern route remains the central practical obstacle to restoring normal shipping volumes.
Oil markets reacted sharply but with measured durability. Brent crude, which had briefly touched $72 earlier Thursday — its closest approach to pre-war levels in nearly four months — reversed course and jumped more than 2%, briefly returning above $75. Energy sector stocks came off their session lows, and shares of major producers Exxon Mobil and Chevron turned briefly positive before paring gains. Airlines, which had been benefiting from declining jet fuel costs throughout the week, came off their session highs. Chevron CFO Eimear Bonner, who had said earlier Thursday that gasoline prices should ease as conditions normalize, saw her comments complicated within hours by the evening's events.
The political backdrop in Washington grew more complex simultaneously. Republican senators reversed their votes on an Iran war powers resolution late Wednesday, according to NBC News, following what was described as a contentious meeting that included a heated exchange between senators and President Trump over the chamber's opposition to the measure. The reversal suggests the administration has strengthened its political position on maintaining executive control over military action related to the conflict, an outcome that shapes the perceived durability of the diplomatic track and the IRGC's calculation of how aggressively to assert maritime authority. For energy investors, the Ever Lovely attack is a reminder that a single IRGC action remains capable of reversing weeks of easing oil price trends within a single trading session, and that the path from diplomatic roadmap to functional strait reopening remains longer and more dangerous than headline progress suggests.
