President Donald Trump issued an executive order Sunday morning directing the United States Navy to establish a total blockade of the Strait of Hormuz. The directive instructs naval forces to prevent any and all vessels from entering or exiting the strategic waterway effective immediately.
The move follows the collapse of high-level negotiations between U.S. and Iranian delegations in Islamabad, Pakistan. Vice President JD Vance announced earlier today that the talks failed to produce a long-term accord regarding Iran’s nuclear program and regional maritime security.
A key component of the president's order focuses on ships currently in international waters. The U.S. Navy has been authorized to seek out and interdict every vessel that has paid a transit toll to the Iranian government.
"No one who pays an illegal toll will have safe passage on the high seas," President Trump stated in a social media announcement regarding the policy. The administration characterizes the fees collected by Iran during the recent conflict as a violation of international maritime law.
Maritime analysts estimate that Iran has been charging shipping firms upwards of $1 million per vessel to transit the strait during the recent period of heightened regional tension. The U.S. now classifies these payments as illegal contributions to the Iranian state.
The U.S. Fifth Fleet, headquartered in Bahrain, is expected to deploy additional assets to enforce the blockade. The Strait of Hormuz remains a critical chokepoint through which approximately 20 percent of the world’s daily oil and liquefied natural gas shipments pass.
Global markets responded to the directive with immediate volatility as Brent crude prices climbed in Sunday trading. Energy experts warn that a total closure of the strait could push prices significantly higher if a resolution is not reached quickly.
International legal scholars are currently debating the implications of the interdiction order for global trade. While the White House maintains the legality of the action, some critics suggest it may challenge established conventions regarding freedom of navigation on the high seas.
Military officials have not yet confirmed the specific rules of engagement for the interdiction of merchant vessels. Defense leaders are currently monitoring for potential naval responses from Iranian forces stationed along the northern coastline of the strait.
