The Swiss Foreign Ministry has confirmed the venue and date: the US-Iran memorandum of understanding is set to be signed on **Friday 19 June 2026** at the Bürgenstock resort in the canton of Nidwalden, with envoys from the United States, Iran, Pakistan and Qatar. Pakistan and Qatar, the mediators, proposed the location. Switzerland is facilitating. The signing was relocated to the Bürgenstock from an earlier plan to sign in Geneva.
That is genuine movement from where this sat 48 hours ago, when the timing was only "in the coming days". But the detail underneath has not moved with the headline.
- **Tehran has not independently confirmed the signing.** Open-source reporting notes Iran has not endorsed the Trump administration's claim that both sides have "digitally" signed an initial deal. - **The blockade is still up.** A US military advisory states the blockade of Iranian naval ports "remains in effect until the agreement is formally completed" — i.e. until Friday's ceremony, not before. - **The strait runs "toll-free for 60 days"** under the framework, and the ceasefire is "cease fighting on all fronts for 60 days". This is an interim instrument, not a settlement. - **No money has moved.** A senior official confirmed "zero dollars of unfrozen assets" have been released to Iran so far.
**Operator implication.** Treat Friday as a milestone, not a green light. A 60-day ceasefire is a clock, not peace, and the parties who matter most for risk — Iran's own confirmation, the Navy's blockade posture — are still trailing the announcement. Movement planning through the Gulf and the strait should hold to the constrained posture until the blockade actually lifts and traffic normalises, not the moment the photo is taken at Bürgenstock. Build the 60-day expiry into any standing plan now.
