Iran and the United States have finalized a memorandum of understanding that, once signed, will trigger immediate negotiations on a comprehensive final deal. The MoU was finalized on June 15, 2026, with an official signing ceremony scheduled for June 19 in Geneva, Switzerland.

The agreement establishes a 60-day negotiation window after signing, during which the two sides will tackle Iran’s nuclear program and the broader shape of bilateral relations.

What’s actually in the MoU

The memorandum includes immediate ceasefire measures, a framework for sanctions relief, and provisions to improve shipping security. The Strait of Hormuz, through which a significant chunk of the world’s oil supply passes, has been a flashpoint in the escalating tensions that defined early 2026. Military operations and naval blockades in the region had ratcheted up pressure on both sides.

The confidence-building measures baked into the MoU are designed to ease financial limitations on Iran while creating enough trust for both parties to sit down and discuss the nuclear file.
