Spencer Fane Attorney Examines Banking Implications of Cannabis Rescheduling

Banking Risk Profile Shifts Under Schedule III

Rescheduling to Schedule III wouldn't remove federal illegality but could reduce the perceived compliance burden for banks serving cannabis clients. Shreves notes that cannabis would remain a controlled substance under the Controlled Substances Act, meaning Bank Secrecy Act obligations and FinCEN guidance would still apply. Schedule III classification historically carries lower enforcement priority. That may encourage more regional banks to enter the space.

The analysis emphasizes that FinCEN's 2014 guidance on marijuana-related businesses would remain the operative framework for suspicious activity reporting and customer due diligence. Banks would still file SARs for cannabis accounts, but the risk weighting assigned to those accounts by compliance officers could shift downward if federal enforcement posture softens.

280E Repeal and Cashflow Improvements

The most immediate banking benefit stems from potential repeal of Internal Revenue Code Section 280E, which currently bars cannabis operators from deducting ordinary business expenses. Shreves highlights that Schedule III substances aren't subject to 280E, meaning cannabis operators could deduct payroll, rent, and operating costs like any other business. That change would materially improve cashflow and reduce the volume of cash transactions banks must monitor.

Improved margins could also expand the pool of bankable cannabis operators. Many small cultivators and retailers currently operate on thin margins that make account-maintenance fees prohibitive. 280E repeal could lift net income by 30 to 50 percent for vertically integrated MSOs, according to prior industry estimates, making those accounts more attractive to commercial lenders.

What Rescheduling Does Not Solve

Shreves cautions that rescheduling alone doesn't provide safe-harbor protections for banks or eliminate state-federal conflicts. The SAFE Banking Act, which would shield financial institutions from federal penalties for serving state-licensed cannabis businesses, remains stalled in Congress. Without that statutory protection, banks face residual legal risk even under Schedule III.

State licensing and compliance remain prerequisites for any banking relationship. Missouri's Division of Cannabis Regulation, for example, requires operators to maintain financial accounts in good standing as a condition of license renewal. Rescheduling doesn't alter those state-level obligations or streamline the patchwork of 38 medical and 24 adult-use jurisdictions.

The next signal to watch is the DEA's final rule, expected in Q4 2026 after the public-comment period closes. Banks will continue to weigh compliance cost against market opportunity on a case-by-case basis.
