The United States has begun what Treasury Secretary Scott Bessent called the “single greatest financial offensive ever marshalled against an adversary,” targeting Iran’s remaining economic lifelines in a campaign dubbed Operation Economic Outcast.
In remarks delivered Monday and an earlier opinion piece, Bessent said the effort aims to sever every source of revenue sustaining the Iranian regime until Tehran stands alone. “Our objective is to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone,” he stated in the Financial Times. He described the move as an “economic D-Day” following prior military actions that the administration claims have dismantled much of Iran’s military capacity and weakened its nuclear program.
New sectoral sanctions target five areas Iran uses to generate funds and evade restrictions: digital assets, technology, gold, aviation and shipping. The Treasury Department’s Office of Foreign Assets Control is also designating more than 60 entities, individuals and vessels linked to illicit oil sales, nuclear and missile procurement, and cyber operations. Countries and companies that continue financial or commercial ties face secondary sanctions and potential exclusion from the U.S. dollar system, with a limited “cure period” to cut connections.
Bessent warned that any nation enabling the regime risks sharing its isolation. “Any nation that serves as a financial artery of a withering regime should expect to share in its isolation,” he wrote. President Donald Trump has reinforced the message, urging allies to join the pressure campaign as Iran’s currency hits record lows and inflation soars.
The campaign builds on existing sanctions and a naval blockade of Iranian ports. Bessent framed it as the endgame: Iran faces either complete isolation and a subsistence economy or a path back toward normal engagement with the global system. Treasury said it has mapped Iran’s sanctions-evasion networks and will pursue a zero-leakage approach.
