US naval blockade of Iranian ports and the Strait of Hormuz, imposed April 13, 2026 after failed Islamabad talks in the 2026 Iran conflict, continues to restrict Iranian maritime trade while Iran maintains its own restrictions on the waterway. Recent bilateral negotiations have produced incremental progress, including pauses in US “Project Freedom” escort operations and Iranian signals on reopening transit under certain conditions. President Trump has linked any full lifting of the US measures to a broader settlement covering nuclear issues and other demands, with the most recent reported announcement of an end to the blockade occurring on May 29 following direct talks. Traders are monitoring further diplomatic statements, any new escalation or de-escalation moves by either side, and scheduled follow-up negotiations that could alter the timeline for formal US action.
