U.S. Secretary of Defense Pete Hegseth and an advisor to Iran's Supreme Leader confirmed this week that the maritime blockade of the Strait of Hormuz remains in effect [1].

The persistence of the blockade maintains high tensions in one of the world's most critical oil transit chokepoints, signaling a stalemate in diplomatic efforts to ease regional pressures.

Speaking during the Shangri-La Dialogue in Singapore in May 2026, Hegseth said that the maritime blockade on Iran is still ongoing [1]. The U.S. government maintains that the restriction continues to exert real pressure on Iran [1].

An advisor to the Iranian Supreme Leader also confirmed the blockade's status during the summit, though he criticized the American approach. He said that President Trump has betrayed diplomacy for a third time by continuing the blockade and presenting excessive demands [1].

Despite the official confirmation of the blockade, reports from the field suggest confusion regarding its enforcement. Iranian sailors, as reported by the Tasnim News Agency, said some ships attempted to cross the blockade line after President Trump announced the lifting of the restriction [1]. Those vessels reportedly faced U.S. warnings to retreat [1].

The economic impact of the restriction extends to third-party nations. Two Canadian cargo ships are currently stuck because of the blockade [2].

Conflicting narratives persist regarding the source of instability in the region. While the U.S. continues its blockade, Washington has accused Iran of obstructing navigation, and threatening global trade through the strait [1].

“The maritime blockade on Iran is still ongoing”

The confirmation of the blockade by both nations, despite reports of an attempted lift, suggests a deep disconnect between public diplomatic signaling and operational military reality. The continued restriction on the Strait of Hormuz ensures that the U.S. maintains economic leverage over Tehran, but the involvement of third-party vessels, such as those from Canada, increases the risk of an international maritime incident.
