-- Oil prices surged 7% on Monday as global markets reacted to President Trump's order for a naval blockade on Iranian cargoes in the Strait of Hormuz, sparking fears of a long-term supply crunch.
The Brent futures contract gained about 7.4% to $102.22 per barrel. The front-month Murban crude contract surged 6% at $104.04 per barrel.
"This morning, the Brent June contract is up 7.4% again to $102.2/b as the negotiations this weekend yielded no results, while the US has also announced a blockade of the Strait of Hormuz. Now clarified to affect only Iranian cargoes," SEB analysts noted.
The primary driver for the price surge is the total collapse of high-level negotiations in Islamabad, Pakistan.
After 21 hours of marathon talks between Vice President JD Vance and Iranian officials, the sides failed to reach a deal regarding Iran's nuclear program and regional conflicts.
In response, President Donald Trump announced a significant escalation via social media.
The US Navy has been instructed to interdict any ships attempting to enter or leave the Strait of Hormuz that are carrying Iranian cargoes.
US forces will begin destroying naval mines allegedly laid by Iran in the shipping lanes.
It also includes seeking out vessels in international waters that have paid transit "tolls" to Iran, which the US has labeled illegal.
President Trump acknowledged the domestic impact on Sunday, noting that gasoline and oil prices are likely to remain elevated through the November midterm elections.
Iranian officials have warned that they maintain full control of the waterway, raising the specter of direct naval confrontations.
