Minnesota Law Opens Crypto Custody To Banks, Credit Unions

Minnesota has enacted a new law (HF 3709 / Session Law Chapter 93) that expressly authorizes state‑chartered banks and credit unions to offer crypto custody services to customers, with key provisions taking effect August 1, 2026.

Core details of the Minnesota law

• Governor Tim Walz signed the virtual currency / digital asset custody bill (often cited as HF 3709) into law in mid‑May 2026.

• The law allows Minnesota‑chartered banks and credit unions to hold “virtual currency” or digital assets (e.g., Bitcoin and other crypto) on behalf of customers within a regulated framework.

• Crypto custody services are permitted beginning August 1, 2026, making Minnesota one of the first U.S. states—and the first in the Midwest—to provide a unified statutory framework for both banks and credit unions.

Scope: who can custody and in what capacity

• State‑chartered banks and credit unions supervised by the Minnesota Department of Commerce may provide custody services if they meet prescribed safety, soundness, cybersecurity, and compliance standards.

• Banks may be authorized to provide custody in fiduciary or non‑fiduciary capacities, while credit unions are generally framed as operating in a non‑fiduciary custodial capacity in commentary around the law.

• Institutions may use third‑party sub‑custodians to handle the technical safekeeping of keys and assets, so long as regulatory expectations are met.

Key customer‑protection and structural requirements

• Customer digital assets must be legally and operationally segregated from the bank’s or credit union’s own assets and cannot be treated as the institution’s property.

• The law defines custody to include safekeeping, controlling, or managing digital assets or their cryptographic private keys, clarifying that these services are subject to traditional oversight for risk management and cybersecurity.

• Institutions must generally notify the Minnesota Commissioner/Department of Commerce at least 60 days before launching crypto custody, with details of their internal risk, compliance, and cyber frameworks.

Positioning in the broader U.S. landscape

• Minnesota joins states such as New York, Wyoming, and Virginia that already have pathways for banks or trust companies to offer digital‑asset custody, but it is the first Midwestern state with a comprehensive framework covering both banks and credit unions in one statute.

• Supporters argue that this gives residents a safer, regulated alternative to offshore or lightly regulated crypto platforms, while helping community banks and credit unions remain competitive as customer interest in digital assets persists.

Practical implications for banks, credit unions, and users

• For institutions, the law is permissive, not mandatory—banks and credit unions can decide whether entering crypto custody fits their risk appetite, infrastructure readiness, and business model.

• For consumers, the main change is the option—starting August 1, 2026—to hold crypto via familiar, state‑regulated depository institutions instead of or in addition to exchanges and specialized custodians, potentially with clearer recourse and supervision.

From your industry lens, the interesting parallels are with how states have gradually opened up authority for banks to hold other non‑traditional assets (e.g., digital documents or escheatment assets), but here with an explicit focus on segregation, advance supervisory notice, and cyber/risk programs that resemble OCC/FDIC expectations for higher‑risk activities.
