As of March 2026, marijuana-related businesses continue to occupy one of the most legally and operationally complex positions in U.S. financial compliance. Federal law still classifies cannabis as a Schedule I substance, leaving financial institutions that bank MRBs exposed to BSA enforcement risk.
FinCEN’s February 2025 data-driven enforcement operation targeting money services businesses along the Southwest border — and the subsequent pattern of escalated scrutiny into 2026 — has highlighted the elevated AML risk profile of cash-intensive businesses in high-risk corridors, a category that frequently overlaps with legal cannabis operations near state-federal legal fault lines.
For financial institutions that have chosen to serve MRBs under FinCEN’s 2014 guidance framework, the compliance burden in 2026 is heightened: enhanced due diligence, mandatory disclosure of MRB customer relationships, and ongoing transaction monitoring are required, but the absence of SAFE Banking Act legislation means there is no federal safe harbor. The Trump administration has shown no appetite to advance cannabis banking reform, and the SAFE Banking Act remains stalled in Congress. Compliance officers at banks and credit unions that serve MRBs must ensure that their programs satisfy the full spectrum of FinCEN expectations — including licensing verification, source of funds analysis, and regular risk reviews of customer business models — to defend against potential enforcement action.
