Cannabis Banking and AML Compliance: Navigating the Federal-State Conflict

8 min read
ShareLinkedInXFacebook

Cannabis businesses operate legally under state law but remain federally illegal. Financial institutions that serve cannabis businesses face unique AML compliance challenges. Here's the current state of the law and the practical compliance framework.

Cannabis businesses operate in a legal gray zone that creates unique compliance challenges for financial institutions. Cannabis is legal under the laws of many states but remains a Schedule I controlled substance under federal law. Financial institutions that provide banking services to cannabis businesses are technically facilitating transactions involving the proceeds of a federal crime - which creates BSA compliance obligations that are unlike those for any other industry.

FinCEN's 2014 guidance on cannabis banking established a framework for financial institutions that choose to serve cannabis businesses. The guidance requires financial institutions to conduct enhanced due diligence on cannabis customers, file specific types of SARs for cannabis-related transactions, and monitor cannabis customer activity on an ongoing basis. The guidance doesn't authorize cannabis banking - it describes how financial institutions can manage the compliance risk if they choose to serve cannabis businesses.

The SAR filing requirements for cannabis banking are unique. Financial institutions that serve cannabis businesses must file "marijuana limited" SARs for transactions involving cannabis businesses that appear to be operating in compliance with state law, "marijuana priority" SARs for transactions that suggest the cannabis business is not complying with state law, and "marijuana termination" SARs when the institution decides to terminate a cannabis banking relationship. These filing categories are specific to cannabis and don't apply to any other industry.

The enhanced due diligence requirements for cannabis customers are extensive. Financial institutions must verify that the cannabis business is licensed under state law, review the business's license and compliance history, understand the business's ownership structure and beneficial owners, and monitor the business's transactions for patterns inconsistent with its stated business purpose. This due diligence must be documented and updated regularly.

The practical reality for most financial institutions is that cannabis banking is a high-compliance-cost activity that requires dedicated resources and expertise. Community banks and credit unions that serve cannabis businesses must be prepared to invest in the compliance infrastructure that the FinCEN guidance requires. Institutions that serve cannabis businesses without implementing the required compliance framework are operating with significant regulatory exposure.
