US launches 'economic D-Day' sanctions campaign targeting Iran's crypto, oil and shipping sectors

The U.S. Treasury Department has launched Operation Economic Outcast, a sweeping sanctions campaign described by Treasury Secretary Scott Bessent as an "economic D-Day" against Iran. The initiative expands secondary sanctions risk to foreign entities operating in five key sectors: digital assets, technology, gold, aviation, and shipping. Alongside sanctioning nearly 60 individuals, vessels, and entities, the U.S. is establishing strict compliance timelines for foreign governments to sever economic ties with Tehran or face exclusion from the dollar-based financial system.
