Overview
- Iran's armed forces announced the closure of the Strait of Hormuz on Saturday, citing continued Israeli attacks in southern Lebanon and accusing the United States of failing to enforce the provisional memorandum.
- The U.S. Central Command said commercial traffic continued through the strait and reported dozens of transits with more than 17 million barrels of cargo monitored, signaling a gap between Tehran's announcement and on‑the‑water conditions.
- High‑level Iranian negotiators including Parliament President Mohammad Bagher Qalibaf and Foreign Minister Abbas Araghchi traveled to Switzerland to press for measures such as unfreezing Iranian assets and visible U.S. compliance.
- U.S. Vice President J.D. Vance arrived in Switzerland on Sunday to join technical talks mediated by Pakistan and Qatar, with preparatory work in Bürgenstock continuing despite an earlier postponed meeting.
- The 60‑day deadline in the memorandum and President Trump’s public threat to impose tolls on the strait after that period raise the stakes for energy markets, regional fighting in Lebanon, and the survival of the provisional deal.
