The United States has announced a maritime blockade on all Iranian ports effective from April 13th, 2026, acting on a proclamation by President Donald Trump in a sharp escalation of the ongoing US-Iran standoff. United States Central Command confirmed the blockade applies to vessels of all nationalities operating in and around Iranian ports and coastal regions across the Arabian Gulf and Gulf of Oman.
The United States Central Command clarified that the restrictions target maritime traffic linked specifically to Iranian ports and that freedom of navigation through the Strait of Hormuz will be maintained for vessels travelling to and from non-Iranian ports. Commercial shipping operators have been advised to stay updated through official broadcasts and maintain active communication with US naval forces while navigating the region.
The move follows the collapse of diplomatic talks between Washington and Tehran in Islamabad, prompting the US to pivot to maritime pressure as a strategic lever. Reports indicate aircraft carriers are already deployed in the Persian Gulf to bolster enforcement capability. Trump asserted that the US Navy holds the capability to decisively outmatch Iran’s blockade measures, backed by aircraft carriers already positioned in the Persian Gulf to reinforce enforcement operations.
Iran has responded with an unambiguous warning. The Islamic Revolutionary Guard Corps stated that any escalation would be met with force, asserting that its forces have the Strait of Hormuz “under full control”. The standoff has raised immediate concerns across global shipping, oil supply chains, and energy markets, with further escalation seen as a credible and near-term risk.
