**US naval blockade enforcement on Iranian ports and vessels, imposed amid the conflict that began in late February 2026 and Iran's restrictions on Strait of Hormuz traffic, has seen repeated shifts tied to diplomatic developments.** Temporary relief followed a June memorandum of understanding, with enforcement later reinstated amid renewed tensions and strikes. As of early October 2026, CENTCOM statements confirm the cessation of blockade operations under recent agreements, allowing increased tanker transits and Iranian oil movements through the Gulf of Oman. Ongoing 60-day negotiations for a broader peace framework, including sanctions considerations and waterway access, along with compliance monitoring and any follow-on diplomatic steps, remain central to whether a formal US announcement ends the measures by targeted resolution dates. Trader assessments reflect these sequenced military-diplomatic developments and the potential for further adjustments.
