FinCEN Hits Pause: No AML Rule for Investment Advisers Until 2028

08 Jan 2026
Client Alert

On December 31, 2025, the U.S. Department of the Treasury’s (“Treasury”) Financial Crimes Enforcement Network (FinCEN) issued a final rule formalizing its previously announced intention to reassess the specific requirements for anti-money laundering/counter-financing of terrorism (AML/CFT) program compliance by registered investment advisers (RIAs) (the “IA AML Rule”) and to delay the rule’s compliance deadline. The IA AML Rule, originally scheduled to take effect on January 1, 2026, is now postponed until January 1, 2028, following concerns raised by certain RIAs and other industry participants facing implementation challenges. The final rule reflects FinCEN’s previous notice of the proposed delay in rulemaking issued on September 22, 2025, as well as the exemptive relief order issued on August 5, 2025, and Treasury’s July 2025 announcement of FinCEN’s intention to postpone and review the IA AML Rule.[1]

As adopted, the IA AML Rule amends the definition of “financial institution” under the Bank Secrecy Act (BSA) to include certain RIAs and exempt reporting advisers (ERAs). This amended definition subjects covered advisers to AML/CFT program requirements, including suspicious activity reporting (SAR) obligations. For more information about the IA AML Rule, please see our September 2024 Client Alert.

In the final rule, FinCEN notes that delaying the effective date will provide FinCEN additional time to review the IA AML Rule and ensure it is effectively tailored to the diverse business models and risk profiles within the investment adviser sector. While we can expect some changes to the IA AML Rule, it is unclear how substantial they will be. FinCEN will also consider timing issues with potential revisions to the IA AML Rule and other rulemakings related to the investment adviser sector (in particular, the joint proposed rule establishing customer identification program (CIP) rule requirements for investment advisers). For more information about the joint proposed CIP rule, please see our July 2024 Client Alert.

Looking Ahead

Our BSA/AML and Investment Management teams are tracking these developments and will monitor for further updates from FinCEN as RIAs and other investment firms consider whether interim changes in compliance programs are appropriate.
