US-Iran Talks Collapse April 26 Drives 15% Oil Surge in 48 Hours

US-Iran talks in Islamabad collapsed on April 26, 2026, as Iran’s Foreign Minister Mohammad Araghchi left before the US team led by Steve Witkoff and Jared Kushner arrived. President Donald Trump canceled the trip, blaming wasted time and infighting, while Israel resumes Lebanon strikes. The breakdown intensifies the Strait of Hormuz blockade since February 28, endangering 20% of global oil exports.
