Strait of Hormuz Reopens for Transit, But Mine Clearing Delays Full Shipping

The Strait of Hormuz has reopened for transit following a recent memorandum of understanding between the United States and Iran, which was announced on June 18, 2026. This agreement immediately lifted the U.S. naval blockade and committed Iran to ensuring toll-free passage for commercial vessels for at least 60 days. Consequently, some stranded ships have already begun to navigate the critical waterway, marking an initial resumption of maritime traffic.

However, the full return to normal shipping operations faces considerable delays due to the presence of approximately 80 mines in the central shipping lanes of the Strait. While Iran is tasked with demining operations as part of the deal, and U.S. forces initiated mine clearance efforts in April, the independent tanker owner trade body has cautioned that the main route remains unsafe. Clearing these numerous underwater explosives is expected to be a time-consuming process, thereby impeding the full resumption of pre-conflict shipping levels.
