President Donald Trump announced a major expansion of United States economic warfare against Iran, threatening severe secondary sanctions against foreign nations and financial institutions that maintain trade ties with Tehran. Writing on Truth Social, Trump declared the initiation of a crushing economic operation, warning that any country allowing businesses, financial networks, airports, or government entities to support Iran will face severe economic consequences. The initiative targets illegal oil smuggling, swap lines, cash transfers, exchange houses, front companies, and foreign ship registries. Treasury Secretary Scott Bessent confirmed that the measures represent an unprecedented attempt to isolate the Iranian economy. The announcement comes amidst continuing disruptions in the Strait of Hormuz, where commercial shipping transits remain severely restricted. Global crude oil prices reacted with upward pressure as energy market traders evaluated potential supply shocks affecting main buyers of Iranian exports.
