FinCEN Engages Global Banks to Disrupt Iran’s Illicit Finance Networks

The U.S. Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN) convened a FinCEN Exchange with global financial institutions on September 16, 2026, as part of Operation Economic Outcast, aimed at disrupting revenue and procurement networks connected to the Iranian regime.

The session focused on helping financial institutions identify the nodes, facilitators, and networks that provide Iran and its terrorist proxies with access to U.S. correspondent banking relationships. Treasury officials and financial institutions also discussed how illicit networks use the financial system to launder funds, procure weapons, and support regional terrorist activity.

Public-private information sharing takes center stage

FinCEN emphasized the role of public-private information sharing in identifying and disrupting illicit finance. The exchange provided financial institutions with threat information, findings, and best practices relevant to Iran, its proxies, and associated enablers.

The Treasury also encouraged financial institutions to review relevant FinCEN alerts, advisories, and financial trend analysis, alongside Iran-related sanctions administered by the Office of Foreign Assets Control (OFAC).

The latest exchange builds on Treasury’s April 2025 Iran Maximum Pressure and Counter Terrorism (IMPACT) public-private partnership event, continuing its engagement with financial institutions and law enforcement agencies.

Key takeaways for compliance professionals

1. Strengthen Iran-related risk detection: Financial institutions should remain alert to networks and facilitators linked to Iranian illicit finance and terrorist financing.
2. Use public-private intelligence: FinCEN’s information-sharing model provides institutions with additional indicators and intelligence to strengthen transaction monitoring and investigative processes.
3. Review regulatory intelligence: Firms should regularly assess FinCEN alerts, advisories, financial trend analysis, and OFAC Iran sanctions information when evaluating related transactions and relationships.

FinCEN Exchange is a voluntary public-private partnership established in 2017 and codified under the Anti-Money Laundering Act of 2020. Its continued use highlights the importance of collaboration between financial institutions, regulators, and law enforcement in identifying high-impact financial crime risks.
