Washington Launches Sweeping Sanctions Campaign to Isolate Tehran

The U.S. Treasury Department announced Operation Economic Outcast on Monday, a new sanctions regime threatening secondary penalties against any nation or entity that continues commercial ties with Iran. Treasury Secretary Scott Bessent said the goal is to sever all economic pipelines sustaining the Iranian government, with nearly 60 individuals, entities, and vessels already targeted. The administration also plans to sanction an unnamed major financial institution by the end of the week.

The sanctions package targets roughly 60 entities linked to Iran's nuclear program, missile development, cyber operations, and oil revenue streams. Secondary sanctions now extend to five additional sectors—aviation, digital assets, gold, shipping, and technology—meaning foreign firms operating in those areas with Iranian ties risk losing access to U.S. markets. Treasury officials also signaled an imminent action against a major unnamed financial institution before week's end.

Iran's currency has already felt the pressure, with the rial plunging to 2.02 million against the dollar. Tehran's negotiator dismissed the measures as rhetorical posturing, while analysts point to Beijing as a likely target given China's ongoing energy purchases from Iran. Meanwhile, Iranian forces continue harassing commercial shipping through the Strait of Hormuz, complicating any diplomatic resolution.
