Overview
- The two presidents signed a 14‑point memorandum that calls for an immediate ceasefire, reopening the Strait of Hormuz, a practical suspension of U.S. oil sanctions, and a 60‑day window to settle nuclear issues; that agreement was signed remotely on Thursday.
- Planned in‑person talks in Burgenstock were postponed on Friday after Iran demanded guarantees on fighting in southern Lebanon and reports said Tehran fired warning shots at ships in the strait.
- On Saturday Iran’s military publicly declared the Strait of Hormuz closed in protest of continued Israeli strikes in Lebanon, but U.S. officials including Vice President J.D. Vance reported no clear evidence of a sustained blockade and maritime trackers showed some commercial transits resuming.
- U.S. and Iranian delegations and mediators reconvened in Burgenstock on Sunday, the first round lasted about 80 minutes and participants said progress was made while teams form technical and monitoring groups to turn the memorandum into operational guarantees.
- The deal’s durability depends on stopping Israel–Hezbollah exchanges, clearing mines and other hazards, and lowering wartime insurance and security risks for shipping, which will determine whether oil flows and regional markets return to stable levels.
