President Trump imposed a U.S. naval blockade on Iranian ports via the Strait of Hormuz around April 12, 2026, after U.S.-Iran peace talks collapsed, aiming to economically pressure Tehran amid its prior closure of the waterway. Iran responded by fully shutting the strait on April 18, but recent proposals to reopen it—conditioned on the U.S. lifting its blockade and ending hostilities—have been reviewed and dismissed by Trump's national security team as inadequate. As of April 30, Trump vows to sustain the blockade until Iran agrees to a nuclear deal and other demands, driving surging oil prices and global uncertainty. Traders watch for upcoming briefings or diplomatic breakthroughs that could prompt an announcement lifting the measures.
