Oil and natural-gas futures surged after U.S.-Iran peace talks collapsed in Islamabad on April 12, 2026, and President Trump announced a U.S. Navy blockade of the Strait of Hormuz, set to begin at 10:00 a.m. ET on April 13.
Oil and Gas Prices Rise Sharply
Brent crude rose as much as 9.1% to $104 per barrel, while West Texas Intermediate (WTI) gained 9.4% to $106. European natural-gas futures climbed about 9% in late trading. Equity futures declined modestly, down roughly 0.4% to 1.2%. The U.S. national average gasoline price stood at $4.13 a gallon, with Washington state near $5.39.
The price moves reflected heightened concerns over near-term supply risks after the diplomatic breakdown and the announced naval blockade.
Blockade Tightens Gulf Oil Supply
U.S.-Iran peace talks in Islamabad ended after more than 20 hours on April 12, with Vice President JD Vance leading the U.S. delegation. Iran refused to abandon its nuclear program, prompting the talks to collapse amid escalating hostilities that began with U.S.-Israel strikes on Iran in late February 2026. Iran had already restricted transit through the Strait of Hormuz, a chokepoint handling roughly 20% of global oil flows, which had fallen to below 10% of pre-conflict levels.
President Trump announced the blockade via social media, directing the U.S. Navy to interdict ships entering or leaving Iranian ports, target vessels paying Iranian tolls, and conduct minesweeping operations. The administration specified the blockade would begin at 10:00 a.m. ET on April 13.
A two-week ceasefire announced on April 7 had been conditional on Tehran reopening the Strait, with a formal ceasefire deadline set for April 22. Analysts said the blockade would likely keep transit at sharply reduced levels, sustaining upward pressure on crude and gas prices. They noted the risk that disruptions to Iranian shipments could prompt other powers to secure flows and raised the possibility of Iranian strikes on regional energy infrastructure.
Strategists pointed to a widening U.S. premium to overseas crude as a sign of rising foreign demand for American barrels amid Gulf supply tightness. They also noted that oil prices, up about 60% from pre-war levels and persisting for eight to nine months, have coincided with elevated short-term borrowing costs in the U.K., near 4.3% for one-year debt.
The upcoming ceasefire deadline and whether Tehran reopens the Strait will be closely watched for signs of whether Gulf flows can normalize and if recent price gains will persist.
