Iran Reasserts Control Over Strait of Hormuz Amid Stalled U.S. Negotiations
Tehran reimposes wartime protocols at the strategic chokepoint as Pakistani mediators attempt to bridge the gap between Washington and Iran.
Iran’s Supreme National Security Council (SNSC) announced on April 18, 2026, that it is maintaining strict wartime control over the Strait of Hormuz. Under these renewed protocols, Iran is demanding vessel information, issuing permits, and charging transit fees, citing the need to counter a U.S. naval blockade. The move follows reports from maritime monitors that Iran’s Revolutionary Guard fired on a tanker on Saturday, forcing an Indian-flagged supertanker and other vessels to anchor or turn back, heightening concerns over a global energy crisis.
On the diplomatic front, Pakistan is acting as a key intermediary between the Trump administration and Tehran. Pakistani Army Chief Asim Munir recently delivered new U.S. proposals to Iranian leadership. While Pakistani officials expressed optimism about reaching a deal before an April 22 ceasefire deadline, Iranian Deputy Foreign Minister Saeed Khatibzadeh indicated that Tehran remains firm against "maximalist" U.S. positions, particularly regarding the handover of enriched uranium. Tehran continues to refuse face-to-face negotiations with Washington at this time.
