Overview
- The memorandum signed on June 18 put an immediate ceasefire in place and prompted U.S. forces to lift a naval blockade, allowing commercial traffic to resume through the Strait of Hormuz while American warships remain in the region to monitor compliance.
- Vice‑President J.D. Vance and U.S. officials said oil flows rebounded quickly, reporting more than 12.5 million barrels moved through the strait in a single night and prompting a drop in global oil prices.
- The deal opens a 60‑day, IAEA‑supervised technical window to resolve core issues including custody and verification of Iran’s enriched uranium, the exact sequencing of sanctions relief, and the mechanics for releasing frozen assets referenced in the memorandum.
- Planned in‑person or ceremonial talks in Switzerland were delayed as teams finalize logistics, with the U.S. delegation pausing an immediate trip while technical negotiations are arranged.
- Implementation faces steep political and regional risks: Iran’s supreme leader approved the pact with reservations, U.S. conservatives and Israeli officials harshly criticized the deal, and ongoing strikes in Lebanon and proxy dynamics could unravel the ceasefire.
