U.S. Lifts Naval Blockade on Iran Following Memorandum of Understanding

The United States has lifted its naval blockade on Iran, ending military enforcement of maritime restrictions and allowing unrestricted passage of vessels to and from Iranian ports and coastal areas. The decision, announced by U.S. Central Command (CENTCOM) on June 18, 2026, was made in accordance with directives from the President. According to CENTCOM's statement, American forces are no longer impeding transit of vessels to or from Iranian ports in the Arabian Gulf and Gulf of Oman, and all U.S. military blockade enforcement efforts have ceased.

The move follows a memorandum of understanding signed between the U.S. and Iran one day prior. While the blockade has been lifted, U.S. naval vessels will remain stationed in the general area to ensure compliance with all provisions of the agreement and oversee its implementation. CENTCOM emphasized that American ships will monitor adherence to the terms and maintain oversight of the accord's execution.

The lifting of the blockade represents a significant shift in U.S.-Iran maritime policy and signals a diplomatic development between the two nations. The continued presence of U.S. naval forces in the region indicates an intent to maintain stability and verify compliance with the newly reached agreement.
