Crude futures settled higher in after-hours trading on Wednesday after the US military launched another round of strikes against Iran, and President Trump declared the interim ceasefire with Iran "over," stoking fears of supply disruptions through the Strait of Hormuz.
Front-month West Texas Intermediate crude futures advanced 6.1% to $74.58 per barrel, while Brent futures rallied 7.3% to $79.45/bbl.
On Wednesday, the US Central Command said the US military had launched fresh strikes against Iran, in response to Tehran attacking commercial vessels in or around the Strait. This marks the second straight day of US strikes against Iran.
"At the direction of the Commander in Chief, US Central Command forces have started conducting additional strikes against Iran to further degrade their ability to threaten freedom of navigation in the Strait of Hormuz," Centcom said in a social media post on X.
The latest military assault came hours after Trump said he may no longer be interested in even trying to reach a deal with Iran, after he declared the recent ceasefire agreement between Washington and Tehran "over" amid renewed hostilities in the Middle East.
Earlier on Wednesday, Centcom posted that over 20 naval warships were patrolling waters across the Middle East.
Iranian Foreign Ministry spokesman Esmaeil Baqaei said that the memorandum of understanding between Iran and the US was not based on the "commitment for commitment" mechanism because there was no sign of good faith in the opposing side's behavior.
Soojin Kim, research analyst at MUFG, said that the latest developments are likely to restore part of the geopolitical premium that had largely unwound in recent weeks, though the broader outlook will depend on whether the conflict escalates further or peace talks resume.
Meanwhile, US commercial crude oil inventories increased by 3 million barrels to 411.4 mmbbls in the week ended July 3, the Energy Information Administration said in its weekly report on Wednesday.
Crude inventories are now about 6% below the five-year average for this time of year, the EIA said.
Aegis Hedging strategists said in a Wednesday note that US crude stocks are now at a deficit of 14.70 mmbbls, or -3.4% to last year, and a deficit of 50.40 mmbbls, or -10.9% to the five-year average.
