President Donald Trump and Iranian President Masoud Pezeshkian signed a memorandum of understanding on Wednesday, June 17, 2026, to end their conflict [1].

The agreement aims to immediately reopen the Strait of Hormuz for navigation [1]. This move is intended to stabilize regional security and improve global oil markets, which have been volatile due to the ongoing war [3].

The signing ceremony took place at the Palace of Versailles in France [2]. French President Emmanuel Macron was present for the proceedings, and the event also included Pakistan’s prime minister [1].

The memorandum serves as a preliminary agreement to cease hostilities between the two nations [1]. By addressing the closure of the Strait of Hormuz, the deal targets one of the most critical maritime chokepoints in the world [3].

President Trump previously discussed the possibility of a peace deal during remarks at Rockland Community College in Suffern, New York [4]. The transition from those discussions to a formal signing in France marks a shift in diplomatic engagement between the U.S. and Iran [2].

Official documents describe the memorandum as a framework for ending the war and restoring navigation rights [1]. The presence of French and Pakistani leadership suggests a multilateral effort to ensure the agreement holds, and regional stability is maintained [1].

The reopening of the Strait of Hormuz is a critical economic lever, as a significant portion of the world's petroleum passes through the waterway. A formal memorandum of understanding suggests a move toward de-escalation, though the preliminary nature of the document indicates that a permanent peace treaty may require further negotiations regarding sanctions and security guarantees.
