Ongoing US-Iran negotiations over Iran's nuclear program, sanctions relief, and regional security remain the central driver of expectations for any Trump announcement lifting the naval blockade of Iranian ports in the Strait of Hormuz, imposed April 13 after earlier talks collapsed. The blockade, which targets vessels to and from Iranian facilities while permitting some non-Iranian transits, has persisted through May operations to escort merchant ships and recent sanctions on Iranian entities seeking to control Hormuz shipping. Trader focus centers on signals from Trump regarding deal progress, alongside periodic vessel incidents and diplomatic exchanges that could accelerate or delay resolution within coming weeks.
