Iranian oil tankers successfully passed through the Strait of Hormuz after the US lifted its naval blockade, marking one of the clearest signs yet that the Memorandum of Understanding (MoU) between the two countries is beginning to take effect.

According to Iranian state-linked outlet ISNA, citing Deputy Foreign Minister officials, Iran confirmed that the US naval blockade restricting Iranian maritime movement is being lifted. The development was reinforced by reports from Al Jazeera, which confirmed that vessels were transiting the waterway and that Iranian tankers had successfully navigated the strait.

The tanker passages serve as a verification mechanism for the MoU, which is expected to be signed on Friday after weeks of intense diplomacy. The latest development suggests both the US and Iran are moving from political commitments to operational implementation.

The next major test will be whether the reopening becomes routine or whether Hormuz remains a controlled corridor subject to Iranian tolls, inspections, or transit restrictions.
