Crude oil futures rose in midday trading on Monday after the US and Iran resumed military attacks for the first time in a month, raising fears that the latest escalation could further disrupt crude supplies and shipping via the Strait of Hormuz.
Front-month West Texas Intermediate crude advanced 2.6% to $85.56 per barrel, while Brent futures climbed 2.5% to $90.35/bbl.
Gelber & Associates strategists said that October WTI trades near $86.23/bbl, up $2.83 or 3.4%, after renewed US-Iran fighting abruptly reversed part of last week's decline.
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 also said in a social media post on Sunday that Iran's energy hub of Kharg Island was being "blown to smithereens", but there was no evidence the island was under attack.
Saxo Bank strategists said that developments in the Middle East have once again dashed the prospects of bringing the conflict to an end.
However, the analysts said that with an estimated 6 - 8 million barrels per day of crude flowing through the strait, the upside risk is, for now, being capped.
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.
On the supply side, Trump said oil from the deal with Venezuela will be used to replenish the US Strategic Petroleum Reserve.
"One of the things I am going to do with the Venezuelan Oil is fill up the Strategic National Reserves," Trump said in a Truth Social post.
Venezuelan interim President Delcy Rodriguez said that the energy agreement with the US would remain in force for 25 years and aim to increase crude output to 1.5 million barrels per day.
