The United States and Iran have agreed to a preliminary memorandum of understanding that would extend a ceasefire, reopen critical shipping lanes, and set the stage for lifting sweeping economic sanctions on Tehran. Bitcoin surged past $82,000 on the news, hitting a three-month high as traders priced in the geopolitical shift.

The MOU, established on June 15, 2026, is scheduled for formal signing on June 19 in Switzerland. It caps more than 100 days of conflict and negotiations that trace back to April 2025, making it one of the most consequential diplomatic developments in the Middle East in years.

What the deal actually includes

The core of the agreement centers on Iran’s nuclear program. Tehran commits to not developing nuclear weapons and to diluting its stockpiles of highly enriched uranium. In exchange, the US has outlined a path toward comprehensive sanctions relief.

The MOU establishes a 60-day window for further negotiations on Iran’s nuclear commitments. The big concessions, like full sanctions removal, depend entirely on reaching a comprehensive agreement within that window.
