April 14, 2026 — U.S. Naval Blockade Now in Effect — Iran Accuses Washington of Piracy.

Blockade Enforcement Begins

The United States Navy began enforcing a blockade of Iranian ports on April 14, 2026, as several U.S. Navy destroyers entered the Strait of Hormuz for the first time since the war began. According to U.S. Central Command, the operation targets only ships entering and leaving Iranian ports, while freedom of navigation will be maintained for vessels transiting to other Gulf states.

Iran's acting defense minister responded by placing the country's armed forces on 'maximum combat alert,' while Foreign Minister Abbas Araghchi accused Washington of 'piracy' in calls with Saudi Arabian and Qatari counterparts. Thousands rallied in Tehran against the blockade. Despite the heightened tensions, at least one Chinese tanker — previously sanctioned by Washington for dealing with Iran — successfully passed through the strait, suggesting the blockade's enforcement may be selective.

The blockade further chokes off traffic through the strait, which has already declined by more than 90% since the conflict began. U.S. Energy Secretary Chris Wright warned that oil prices will 'keep rising' until 'meaningful ship traffic' gets through the waterway, adding that he expects this to occur 'sometime in the next few weeks.'
