Crude futures settled lower in after-hours trading on Tuesday as markets weighed signs of progress toward restoring shipping via the Strait of Hormuz, while President Trump said all water mines had been removed or detonated from the strategic waterway.
Front-month West Texas Intermediate crude tumbled by 5% to $81.11 per barrel, while Brent futures were down 5.5% to $87.09/bbl.
Saxo Bank strategists said that with no further military escalation and some tankers slipping through the Strait of Hormuz after buying heavily discounted oil to compensate for elevated transit risk, the market remains in limbo.
Oman's Foreign Minister Sayyid Badr Albusaidi arrived in Iran on Tuesday, where he met his Iranian counterpart to discuss future arrangements for the strait.
Oman and Iran have agreed to work toward restoring safe navigation through the Strait of Hormuz, including the creation of a temporary joint navigational corridor and a project to clear mines at key energy chokepoints.
"I am hopeful we will soon announce a temporary corridor for the Strait of Hormuz and practical arrangements to restore safe navigation," Albusaidi said in a social media post on X, describing his meeting with Iranian Foreign Minister Abbas Araghchi as "constructive".
On Tuesday, Trump said that the US Navy had removed or detonated all mines in the Hormuz and warned Iran that any attempt to lay new mines would trigger an immediate military response.
"Iran has been notified that any ship or boat placing new mines will be immediately and systematically destroyed," Trump said in a post on Truth Social.
Trump's Hormuz demining remarks come as the US intensified economic pressure on Iran on Monday but fell short of imposing secondary sanctions on Tehran's trading partners.
Bjarne Schieldrop, chief commodities analyst at SEB Research, said that the US is threatening Iran with economic destruction via sanctions, but China, the leading buyer of Iranian crude, is strongly opposed to sanctions.
US Treasury Secretary Scott Bessent unveiled what he called an "unprecedented" Washington campaign to sever Tehran from the global economy on Monday, warning that any state doing business with the country risks facing US sanctions.
However, Secretary Bessent said that countries will face a specific timeline to shut down links with Iran or face unilateral punishment.
Iranian officials condemned the US sanctions campaign, with Speaker of Parliament Mohammad Bagher Ghalibaf saying Washington lacks the economic leverage to further restrict Tehran's relations with other countries.
Ghalibaf posted on X on Monday that the US is not in an economic position to further restrict its relations with other countries.
Meanwhile, threats to energy flows remain elevated, with the UK Maritime Trade Operations reporting on Monday that an oil tanker was struck and disabled by a projectile off the Omani coast, in the strait.
On Monday, the UKMTO reported an attack on a tanker 63 nautical miles west of Yanbu, Saudi Arabia. The vessel was struck by an unknown projectile, causing a fire on the main deck.
