Economic D-Day: U.S. President Trump ordered a halt to all talks with Iran and escalated “economic warfare and isolation on an unprecedented scale,” warning any country offering a “lifeline” to Tehran—via banks, airports, oil smuggling, cash transfers, ship registries, or front companies—will face “tremendous” consequences; Sanctions Push: Treasury Secretary Scott Bessent says the U.S. will unveil the “toughest sanctions in history” and signals Washington is likely to avoid large-scale combat, leaning instead on maximum economic pressure; Oil & Hormuz Pressure: Oil jumped to a more than three-week high as the expired U.S.-Iran MoU left the Strait of Hormuz effectively blockaded, while reports say the U.S. is running a covert corridor to keep some tanker traffic moving; Tehran Response: Iran’s foreign minister Abbas Araghchi called the threats “economic terrorism” and a diversion from U.S. debt and rising interest costs, while Iran’s central bank chief said oil exports have fallen to zero; Regional Politics: Iran’s parliament speaker Mohammad Bagher Ghalibaf visited Iraq to “reshuffle relations” amid militia disarmament deadlines and Hormuz-linked economic strain, and Iran also moved to expand economic cooperation with Afghanistan; Diplomatic Friction: France expelled an Iranian cultural attaché amid broader Tehran-Paris tensions, and Iranian diplomats told Cyprus it is safe unless British bases are used against Iran.
