Oil prices rise as fresh US-Iran strikes threaten Hormuz shipments

Oil prices surged over 4% on Monday, July 13, 2026, as energy shipments via ​the Strait of Hormuz remained under threat, with the United States and ‌Iran announcing renewed military strikes.

Brent crude futures climbed $3.10, or 4.08%, to $79.11 by 0325 GMT, while U.S. West Texas Intermediate crude rose $2.95, or 4.11%, to $74.36 a barrel.

The United States Central Command said U.S. forces completed another wave of strikes ​against Iran on Sunday, hitting dozens of targets at multiple locations with ​precision munitions.

Iran’s Revolutionary Guards said on ⁠Monday they attacked U.S. military bases in Kuwait and Bahrain.

U.S. President Donald Trump said ​on Sunday that the Strait of Hormuz is open to commercial traffic, although Iran ​declared earlier that it closed the strait after a vessel traveled on an unapproved route and was struck.

Some 20% of the world’s oil and liquefied natural gas transited the strait before ​the war began at the end of February.

Ship-tracking data from Kpler showed that six vessels transited the strait on ​Sunday, the lowest number in five weeks.

The escalating attacks cast further ‌doubt ⁠on the future of an interim U.S.-Iranian agreement signed in June that aimed to reopen the strait and end the war after a further 60 days of negotiations, Reuters reported.

Following the agreement, global oil supply rose by 4.1 million barrels per day in ​June, but remained 9.4 ​million bpd below ⁠pre-war levels, the International Energy Agency said in its monthly report on Friday.

“Hopes of a relatively quick resolution to the recent ​skirmishes may be in doubt after tension escalated over the ​weekend,” ANZ ⁠analysts said in a note.

IG market analyst Tony Sycamore said the relatively tame rise in oil prices suggested the market was taking the view that the current flare-up ⁠represented an ​escalation within a fragile truce and fell well ​short of a complete collapse of the ceasefire.

“How accurate that view is remains to be seen,” Sycamore in a statement.
