Trump signs preliminary Iran deal with parliament speaker; Strait of Hormuz to open Friday
President Donald Trump and Vice President J.D. Vance signed a preliminary agreement with Iran’s parliament speaker on Monday, paving the way for an end to the war and the reopening of the Strait of Hormuz from 19 June.
Signing of the preliminary agreement
President Donald Trump, Vice President J.D. Vance and Iranian parliament speaker Mohammad Bagher Ghalibaf signed a memorandum of understanding to end the war between the United States and Iran, senior White House officials confirmed on Monday. The signing comes as Trump landed in Geneva ahead of the G7 summit in France. The officials, speaking on condition of anonymity, said the document is a preliminary framework for a final peace deal.
The agreement means the Strait of Hormuz will open for everyone from Friday, 19 June.
Nuclear weapons and the Strait of Hormuz
The agreement stipulates that Iran will not possess nuclear weapons, with strict verification measures in place. Trump stated that the final document will be signed by Vice President Vance and its full content will be released after 19 June. The reopening of the strait, a critical oil chokepoint, is the most tangible immediate outcome announced so far.
Sanctions and conditions
Trump stressed that sanctions on Iran would not be lifted until Tehran meets its obligations. The administration has not disclosed the timeline for sanctions removal, linking it to Iran’s compliance with the yet-to-be-published technical details. An anonymous official noted that supreme leader Mojtaba Khamenei did not sign the agreement, as is customary; his predecessor Ali Khamenei also did not sign the 2015 JCPOA. The White House described Ghalibaf as the most influential official in this process.
Details of the agreement will be published within the next 24-48 hours.
Next steps: from details to final ceremony
Technical negotiations on the nuclear program specifics are set to begin this week. The formal signing ceremony is scheduled for Friday, 19 June, after which the full text will be made public. The timeline below captures the key milestones announced so far.
- Trump, Vance and Ghalibaf sign memorandum of understanding in Geneva.
- Deadline for publishing details of the agreement (within 24-48 hours).

Diplomatic backdrop
Trump’s presence in Geneva underscores the international dimension of the deal. The G7 summit in France will likely see discussions on implementation and monitoring. Iran’s commitment to the nuclear clause and the strait’s reopening will be closely watched by energy markets and regional powers.
