Trump Reimposes Naval Blockade on Iran and Declares 20 Percent US Toll on Hormuz Shipping

President Trump announced on Truth Social Monday that the US will reinstate its naval blockade on Iranian ports and impose a 20 percent charge "on all cargo shipped" through the Strait of Hormuz, declaring the US the "GUARDIAN OF THE HORMUZ STRAIT" 12. US Central Command said the blockade takes effect Tuesday at 4 p.m. ET and applies only to Iranian vessels and their customers, with other countries retaining "fair and open use of the Strait" 2. A US defense official told Axios roughly 20 ships have transited the strait's southern route in coordination with the US, with several more transiting without coordination 1. Iranian Foreign Minister Abbas Araghchi responded on X that Iran, not the US, controls the strait and should be compensated instead, calling 20 percent "too much" 2, while the UN's International Maritime Organization said it "stands firmly against charging fees for passage through straits used for international navigation" 2.
