US Treasury Opens Operation Economic Outcast Against Iran

Treasury Secretary Scott Bessent announced on August 24 that the United States has begun Operation Economic Outcast, a campaign designed to cut every remaining economic lifeline of the Iranian regime.

Speaking at the Treasury Department in Washington, Bessent said the measures expand secondary sanctions risk across five sectors that Iran uses to generate revenue and evade existing restrictions: digital assets, technology, gold, aviation and shipping. The department also sanctioned more than 60 entities, individuals and vessels linked to oil smuggling, nuclear and missile procurement, and cyber operations.

"Around the globe, our objective is to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone," Bessent said. He described the effort as a zero-leakage approach and compared the moment to an economic D-Day.

The announcement comes after months of military stalemate. Nuclear talks collapsed weeks earlier. Iran's rial fell to a record low of about 2.02 million to the dollar on the open market the same day. Oil prices declined as traders weighed the risk of further disruption in the Persian Gulf.

Iranian officials responded by warning that any nation supporting the new measures would face consequences they described as an act of war. Mohsen Rezaei of Iran's Supreme National Security Council said Tehran could target alternative oil shipping routes. Iranian state media also warned vessels in the Strait of Hormuz of possible fines, detention or confiscation for violating transit rules.

Bessent said President Trump is personally calling world leaders to urge them to end commercial ties with Iran. The Treasury suspended several existing licenses that had allowed limited payments and cultural exchanges. Bank Melli branches abroad were ordered closed.

The campaign shifts the primary pressure from kinetic action to financial isolation until at least after the U.S. midterm elections. Whether the secondary sanctions will force a change in Iranian nuclear or regional policy remains the central open question.
