U.S. Launches Operation Economic Outcast, Expanding Iran Sanctions Across Five Sectors

The U.S. Department of the Treasury on August 24, 2026 launched Operation Economic Outcast, a new whole-of-government campaign to intensify economic pressure on Iran and expand the reach of U.S. sanctions against third parties that continue to support the Iranian economy.

Treasury said the campaign broadens the categories of Iran-related conduct that may be exposed to secondary sanctions and establishes five priority sectors: digital assets, technology, gold, aviation and shipping. The department said these sectors are being used by the Iranian government to sustain revenue, procurement and international economic links.

Nearly 60 entities, individuals and vessels sanctioned

As part of the launch, the Office of Foreign Assets Control sanctioned nearly 60 entities, individuals and vessels across multiple jurisdictions. Treasury said the targets support activities including illicit nuclear and missile technology procurement, cyber operations and oil-revenue generation networks.

Public reporting on the Treasury announcement identifies affected networks and entities across jurisdictions including the United Arab Emirates, Hong Kong, China, Singapore, Switzerland and Europe. The designations form part of the wider campaign rather than a criminal prosecution; sanctions designations should not be treated as criminal convictions.

Treasury also suspended several general licences that had previously authorised certain remittance payments to Iran and aspects of Iranian access to the U.S. cultural and academic system. OFAC separately issued additional guidance on sanctions risks associated with complying with Iranian demands affecting shipping through the Strait of Hormuz.

Secondary-sanctions and AML exposure

Treasury Secretary Scott Bessent said U.S. authorities are engaging foreign governments and institutions and expect identified Iran-related activities to be shut down within defined timelines. He also warned that entities facilitating money laundering or sanctions evasion for Iran risk being cut off from the U.S. financial system.

Reporting from the August 24 Treasury briefing also indicates that U.S. authorities expect further actions, including potential measures against a major financial institution, although no institution had been named at the time of the announcement.

For compliance teams, the significance of Operation Economic Outcast is broader than the individual designations. The expansion into digital assets, gold, aviation, technology and shipping increases the importance of screening not only named sanctioned parties but also ownership, intermediaries, trade routes, payment flows and counterparties that may create secondary-sanctions exposure.
