EMEA crude futures settled higher in after-hours trading on Monday as renewed US-Iran hostilities revived concerns about disruptions to crude shipments through the Strait of Hormuz, with President Trump reportedly vowing to respond to Tehran's attacks on US forces.
Brent crude futures gained 2.8% to $90.55 per barrel, while Dubai 1st Line Futures rallied 5.1% to $91.18/bbl.
Saxo Bank strategists said that it jumped as fresh fighting flared in the Middle East and the US signaled it was likely to unveil new secondary sanctions on Iran.
On Monday, Trump reportedly said that the US is going to hit Iran "very hard," after Tehran launched attacks on American army bases in Jordan and the UAE in response to Washington's strike on Larak Island in the strait over the weekend.
US Central Command said it fired on Iran's Islamic Revolutionary Guard Corps forces after they were seen preparing to deploy mines into Hormuz.
CENTCOM said in a statement that US forces took "limited, precise" action against minelaying forces of IRGC that posed an "imminent threat" in the strategic waterway, without giving details.
On Sunday, Trump heightened his military threats against Iran to Kharg Island, the country's main oil export terminal, saying in a social media post on Truth Social that it's "going to be blown to smithereens!"
Fueling bullish sentiment, Iranian media said that an unidentified supertanker attempting to pass through the southern route in Hormuz was hit by two mines early on Monday and claimed that the country's authorities seized a bulk carrier near the port of Bandar Abbas in the Persian Gulf.
However, CENTCOM said in a social media post on Monday that no ships had hit mines in the strait.
ING strategists said the key is whether US-Iran clashes ignite further rounds of strikes from both sides and whether they leave shippers hesitant to navigate the Strait of Hormuz.
Meanwhile, Iranian President Masoud Pezeshkian struck a milder tone on Monday, telling Pakistani Prime Minister Shehbaz Sharif on the sidelines of a regional security meeting in Kyrgyzstan that Tehran still sought a negotiated resolution of the conflict.
Separately, Iran's Foreign Ministry said on Monday that the US and its allies bear "full responsibility" for the consequences of the escalation and that it will respond decisively to any further military aggression by the "enemy."
"Some Gulf barrels continue moving through the strait, tempering the rally, but the first direct military exchange in a month has forced traders to rebuild a meaningful near-term supply premium," Gelber & Associates analysts said in a note said on Monday.
On the supply side, Trump said that the US struck a deal with Venezuela to get majority control of over 65 billion barrels of oil reserves as the war with Iran roils the global crude trade.
Venezuelan interim President Delcy Rodriguez said on Saturday that an energy agreement with the US would remain in force for 25 years and target an increase in crude output to 1.5 million barrels per day.
