FinCEN Seeks Whistleblower Tips on Iran-Related Illicit Finance Under Operation Economic Outcast

The U.S. Financial Crimes Enforcement Network (FinCEN) has issued a new whistleblower bulletin seeking information on Iran-related illicit finance as part of the Treasury Department’s Operation Economic Outcast.
FinCEN said on 10 September 2026 that it welcomes information about individuals or entities that may be violating the Bank Secrecy Act or sanctions programmes administered by the Office of Foreign Assets Control. The request specifically includes potential violations involving Iranian proxies and facilitators operating outside Iran.
The bulletin brings FinCEN’s whistleblower programme directly into the wider U.S. campaign against Iranian illicit finance. The programme covers information concerning possible violations of the Bank Secrecy Act and several U.S. national-security and sanctions statutes. Individuals who voluntarily provide qualifying information may be eligible for an award if their information leads to a successful Treasury or Department of Justice enforcement action resulting in more than $1 million in monetary penalties, subject to the statutory and regulatory requirements of the programme.
FinCEN also said Treasury is prepared to take enforcement action against foreign companies supporting illicit Iranian commerce and, where appropriate, against foreign financial institutions and companies facilitating Iranian activities that violate U.S. anti-money laundering or sanctions laws.
Compliance significance
The bulletin does not create a new reporting obligation for financial institutions. Its significance is that Treasury is widening the channels through which it seeks intelligence on sanctions evasion and illicit finance, including information from insiders and other persons with direct knowledge of cross-border structures.
For financial institutions and other regulated businesses with exposure to Iran-related trade, payment flows or counterparties, the development reinforces the importance of identifying indirect links involving intermediaries, offshore facilitators, front companies and other structures that may obscure the ultimate parties to a transaction.
