US Treasury Secretary Scott Bessent announced on Monday a worldwide economic pressure campaign against Iran, dubbed Operation Economic Outcast. He said the United States would seek to target Tehran’s revenue sources, including oil, and deter countries and companies from conducting business with Iran through the threat of secondary penalties.

Bessent described the initiative as “economic D-day” and said its objective was to sever economic support for Iran until Tehran is isolated. He warned countries and entities involved in transactions that turn Iranian oil into money that they could be targeted, saying no one was beyond the reach of US sanctions. He also said President Donald Trump had called world leaders with requests to end interaction with Iran.

The sanctions push comes nearly six months into a war involving Iran, the United States and Israel, according to the source. It said attacks and diplomacy have not resolved the crisis, while Tehran has responded with regional missile and drone attacks and asserted control over the Strait of Hormuz. US officials said the new measures would target digital assets, technology, gold, aviation and shipping.
