April 12, 2026 — Strait of Hormuz: From Iranian Blockade to U.S. Naval Blockade.

Full Naval Blockade Ordered

President Trump announced the U.S. Navy would immediately begin a full blockade of the Strait of Hormuz, interdicting all vessels that paid transit tolls to Iran. The 21-million-barrel-per-day chokepoint now faces competing blockade threats from both sides. Crude oil is expected to surge past $100 when markets open Monday.
