Multiple outlets report that clearing potential mines in the Strait of Hormuz could take weeks, even after an interim arrangement that allows some vessels to move through or near the waterway. Reuters-cited shipping and maritime security sources say minesweeping would likely involve conventional minesweepers and underwater drones and could last about 40 to 50 days before many insurance, shipping, or oil companies consider it safe enough to resume typical passage through the strait. The timing could therefore delay a full return to normal shipping traffic.
Sources cited across the reports say it is not clear how many mines Iran has laid. Iran has asserted control over the waterway during the war and has threatened to deploy naval mines, though it does not comment on whether mines are present. The US says it has targeted Iranian mine-laying boats.
Several reports also highlight the economic impact: the strait handled roughly 20% of global daily oil and liquefied natural gas supply before the conflict, and minesweeping delays could compound already disrupted flows following attacks on Iran on February 28. France 24 additionally notes that some ships may divert via an alternative corridor near Oman, and recent attacks underscore the challenges of guaranteeing safe navigation.
Key points are broadly consistent: mines presence is uncertain, clearance could take 40–50 days, and disruption to maritime traffic and energy supply continues.
