Iran’s chief negotiator Mohammad Bagher Ghalibaf is set to attend the ceremonial signing of a memorandum of understanding with the United States on June 19 in Switzerland. The deal aims to wind down the 2026 Iran conflict, reopen the Strait of Hormuz, and extend a fragile ceasefire.
The MOU was already digitally signed on June 15 by President Donald Trump, Vice President JD Vance, and Ghalibaf himself. The Switzerland event is the formal handshake, the part that makes the history books.
What the deal actually covers
The MOU contains 14 points, and the most consequential ones focus on immediate military de-escalation. A 60-day extension of the ceasefire sits at the center, buying both sides time to negotiate the harder questions that neither wants to answer right now.
Toll-free reopening of the Strait of Hormuz is another headline provision. Roughly 20% of the world’s oil passes through that chokepoint on any given day, so its closure during the conflict created exactly the kind of supply shock you’d expect. The deal also formally ends the naval blockade that had been squeezing Iranian trade routes.
