The 60-day negotiation window established by the June 2026 Islamabad Memorandum of Understanding between the United States and Iran expired on August 17 without formal extension or a final peace accord covering nuclear issues, sanctions relief, or the Strait of Hormuz. President Trump stated publicly that Washington would not extend the MOU, citing insufficient progress and unmet U.S. conditions, while Iranian officials pointed to alleged violations and insisted on returning to prior interim commitments before any further talks. Deadlocked diplomatic channels, mediated by Pakistan and Qatar, showed no last-minute mutual consent despite earlier ceasefire signals. Trader consensus at near-certainty for no extension reflects the confirmed passage of the deadline and explicit statements from both sides. Late developments such as renewed mediator proposals or shifts in military posture on the ground could still prompt informal continuation of talks, though these would not retroactively alter the MOU timeline.
