The US naval blockade on Iranian ports, reimposed in July 2026 after a brief suspension tied to the June Islamabad Memorandum of Understanding, remains in active enforcement as of mid-October. CENTCOM reports redirecting over 135 vessels, disabling several others, and preventing Iranian crude exports through the Strait of Hormuz amid efforts to pressure Tehran on oil revenues and broader security issues. Iran has outlined seven conditions for reopening the waterway and resuming full negotiations, while rejecting US proposals as insufficient; talks continue indirectly alongside US strikes and sanctions measures. Upcoming diplomatic deadlines under the MOU framework and any shifts in enforcement or bilateral statements could influence the timeline for an official US announcement ending the blockade.
