Iran reimposes restrictions on Strait of Hormuz accusing US of violating deal

Iran's joint military command announced on Saturday that it has restored strict control over the Strait of Hormuz, reversing a brief opening declared the previous day. The move cites the United States' continued naval blockade of Iranian ports, despite a recent deal tied to a ceasefire in Lebanon. Tehran warned that passage requires Iranian authorization until the US lifts its restrictions.

This escalation threatens global oil supplies, as the strait handles about 20% of the world's seaborne oil trade. It heightens tensions in the ongoing US-Iran conflict, potentially disrupting energy markets and complicating ceasefire efforts in the region. Oil prices have fluctuated amid hopes for talks over the weekend.

Iranian Perspective

The US violated a deal by maintaining its blockade of Iranian ports, forcing Iran to reinstate strict management of the Strait of Hormuz. Passage will follow designated routes with authorization from Iranian forces until freedom of navigation to Iran is restored. Parliament speaker Mohammad Bagher Ghalibaf emphasized that the strait will not stay open under ongoing US pressure.

US Perspective

President Trump stated that the US will keep its naval blockade in place until a full deal is secured, including Iran removing enriched uranium. He rejected any Iranian restrictions or tolls on the strait and expressed confidence in upcoming talks. The blockade targets Iranian ports amid broader negotiations.

  • The Strait of Hormuz lies between Iran and Oman, spanning just 21 miles at its narrowest point.
  • Mohammad Bagher Ghalibaf served as Tehran's mayor and IRGC commander before becoming parliament speaker.
  • Iran has mined the strait during past crises, like the 1980s Tanker War with Iraq.

US-Iran Ceasefire War

The United States launched military strikes against Iran on June 26, 2026, in response to a drone attack on a commercial cargo ship in the Strait of Hormuz, calling it a "foolish violation" of the 60-day ceasefire agreement signed just days earlier[2][4][14].
