Hopes of a major diplomatic breakthrough between Iran and the United States appear to be fading rapidly after fresh disagreements emerged over the release of Tehran’s frozen assets, threatening a proposed agreement aimed at easing Gulf tensions and reopening the strategically critical Strait of Hormuz. Iranian media reports suggest Tehran is refusing to move forward unless Washington agrees to release a portion of blocked Iranian funds during the very first phase of the deal. The conflict has exposed deep mistrust between the two sides despite months of indirect negotiations, regional mediation efforts and backchannel diplomacy involving Pakistan and several Middle Eastern countries. The renewed deadlock has also raised concerns over energy market stability, as the proposed framework was expected to help restore normal shipping activity through one of the world’s most important oil transit routes.
