EMEA crude futures diverged in after-hours trading on Thursday, trimming earlier gains, as renewed optimism over a potential US-Iran peace deal helped offset geopolitical risk premiums tied to Middle East supply concerns.
Brent crude futures slipped 0.51% to $93.81 per barrel, while Murban oil futures climbed 3.76% to $93.31/bbl. Prices rallied earlier Thursday after the US and Iran exchanged military strikes.
"The market remains caught between pricing the prospect of a deal and the growing realization that a resolution still looks increasingly elusive," Saxo Bank strategists said on Thursday.
US and Iran negotiators have reportedly reached a tentative agreement for a 60-day ceasefire extension and the start of talks on Tehran's nuclear program. However, the agreement between the US and Iran still needs final approval from President Trump, who has told mediators he wants a few days to make the final decision.
The tentative agreement comes at a moment when the fragile ceasefire between the US and Iran appeared to be wavering.
On Thursday, Iran's Revolutionary Guard targeted a US air base in Kuwait with ballistic missiles, which the US Central Command said were successfully intercepted.
The attack came after US forces launched fresh strikes in Iran against a military site believed to threaten American troops and commercial shipping through the Strait of Hormuz.
Saxo Bank analysts said Brent crude surged on Wednesday after renewed US attacks near the Hormuz and retaliatory IRGC strikes targeting US bases, underscoring the limited prospect for a near-term peace deal as the two sides remained far apart on steps needed to reopen the Strait.
On Wednesday, the US Treasury Department sanctioned Iran's Persian Gulf Strait Authority, accusing the agency of extorting commercial vessels in the strategic waterway to fund the Islamic Revolutionary Guard.
"The Iranian military's latest attempt to extort global maritime trade is proof that Economic Fury has left the regime desperate for cash," Treasury Secretary Scott Bessent said.
Secretary Bessent separately warned Oman against collaborating with Iran over a tolling mechanism.
"Oman, in particular, should know that the US Treasury will aggressively target any actors involved - directly or indirectly - in facilitating tolls for the Strait and any willing partners will be penalized," he said.
Meanwhile, the latest diplomatic developments and sanctions came as the US increased pressure on Iran with its naval blockade to choke off Iranian oil revenues. The US military has redirected 111 Iran-linked commercial vessels and disabled four others since imposing the blockade on April 13, the CENTCOM said on Thursday.
