U.S. Officially Ends Maritime Blockade of Iran

The United States has formally ended its maritime blockade of Iran, with U.S. Central Command announcing Wednesday that all enforcement operations targeting vessels entering or leaving Iranian ports have ceased.

“Today, U.S. forces lifted the blockade on all maritime traffic entering and exiting Iranian ports and coastal areas, in accordance with the President’s direction,” CENTCOM said in a statement. “American forces are not impeding the transit of vessels to or from Iranian ports on the Arabian Gulf and Gulf of Oman. All U.S. military blockade enforcement efforts have ceased.”

The announcement marks the clearest operational shift yet following the memorandum of understanding signed by Washington and Tehran aimed at ending months of conflict that disrupted one of the world’s most strategically important waterways.

While the blockade has been lifted, CENTCOM said U.S. naval forces will remain in the region to oversee implementation of the agreement.

“Our great Naval Ships will remain in the general area to make sure that all aspects of the agreement are adhered to, obeyed and in full force and effect,” the statement said.

The end of the blockade was also confirmed by the Joint Maritime Information Center (JMIC), which issued an advisory on June 18 detailing “the end of the U.S. blockade of Iranian ports and coastline.”

The organization said the maritime security threat level for the Arabian Gulf, Strait of Hormuz and Gulf of Oman had been reduced to SUBSTANTIAL following the U.S.-Iran memorandum of understanding, while continuing to advise vessels to coordinate with NAVCENT NCAGS regarding safe transit routes.

The blockade, which began earlier this year amid escalating tensions with Iran, fundamentally reshaped shipping patterns in and around the Strait of Hormuz. As of June 14, U.S. forces had disabled 9 vessels suspected of violating sanctions or attempting to transport Iranian oil, while 142 commercial ships were redirected away from Iranian ports. 

Although the lifting of the blockade removes U.S. military restrictions on commercial shipping, significant uncertainty remains over how quickly traffic will return to pre-conflict patterns.
