Minnesota legalises crypto custody for banks and credit unions
HF 3709 takes effect August 1, making Minnesota the first midwestern state with unified digital asset custody rules for depository institutions.
Briefing
- Minnesota banks and credit unions gain explicit legal authority to custody digital assets starting August 1, the first unified framework of its kind in the midwest.
- Governor Tim Walz signed HF 3709 into law, clearing the final legislative hurdle for depository institutions to enter crypto custody.
- Institutions may provide digital asset custody in a nonfiduciary capacity only, limiting their liability exposure relative to full fiduciary custody arrangements.
- The August 1 effective date gives Minnesota-chartered banks and credit unions roughly ten weeks to build or contract custody infrastructure before the window opens.
Analysis
- Minnesota's law accelerates a state-level custody race that pressures national custody-focused fintechs and traditional bank custodians simultaneously. As midwest banks can now build or contract infrastructure by August 1, third-party custody providers such as Anchorage Digital, BitGo, and Fireblocks gain a short-cycle sales pipeline from institutions seeking to outsource rather than build. Banks entering as fiduciary-light custodians compress the fee premium that specialist crypto custodians currently extract from institutional clients with no bank alternative.
Historical Context
- Jan 2021
OCC issued Interpretive Letter 1174 allowing federally chartered banks to use public blockchains and stablecoins for payment activities, triggering a wave of state-level frameworks as states sought to extend equivalent authority to their own chartered institutions before the federal framework solidified.
- 2019
Wyoming passed the Special Purpose Depository Institution charter, the first US law granting banks explicit digital asset custody authority. It created a licensing template that subsequent states including Nebraska and Montana adapted, establishing the precedent Minnesota is now following.
