Minnesota Governor Tim Walz signed HF 3709 on Friday, enacting a law that allows state-chartered banks and credit unions to offer cryptocurrency custody services starting Aug. 1, 2026. Institutions must maintain written policies covering risk management, internal controls, and security, and must file those frameworks with the Minnesota Commissioner of Commerce at least 60 days before launching. The bill also requires client assets to be segregated from the institution's own holdings — the same protective architecture that traditional brokerage custody runs on.
Why it matters
The legislation adds Minnesota to a growing patchwork of states that have explicitly authorised regulated banks to hold client crypto. New York, Wyoming, and Virginia have already cleared similar paths, and the Minnesota Credit Union Network, the state's trade body, framed the law as giving residents a safer alternative to unregulated out-of-state or offshore custodians. Rep. Bernie Perryman, a main author, said the bill is designed to let Minnesota-based institutions "evolve alongside their customers and members." The combination of risk-management policies, pre-launch notice, and asset segregation sets a higher operational bar than the bare-bones state authorisations that came before it.
Market impact
The custody path is the legitimising beat — banks getting into holding client crypto is a structural on-ramp that makes spot Bitcoin and Ethereum exposure usable for institutional balance sheets that cannot touch self-custody or offshore venues. The near-term trade is the custody technology stack: sub-custodians, qualified custodians, and the insurers that price the underlying asset-segregation requirements. Watch the Commissioner's 60-day notice docket once Aug. 1 lands — filings there will name the first wave of Minnesota-chartered banks and credit unions entering the market, and the order they file will signal how quickly the policy converts into actual client accounts.
Frequently asked questions
-
What does Minnesota's new crypto custody law actually do?
HF 3709, signed by Governor Tim Walz on Friday and effective Aug. 1, 2026, permits state-chartered banks and credit unions to offer virtual-currency custody services, subject to written risk-management policies, asset segregation, and a 60-day pre-launch notice to the Commissioner of Commerce.
-
Which states already let banks offer crypto custody?
New York, Wyoming, and Virginia have already authorised regulated banks to provide crypto custody services. Minnesota's HF 3709 adds asset segregation and a pre-launch notice requirement on top of the existing template.
-
How do banks have to protect client crypto under the Minnesota law?
Institutions must maintain written policies covering risk management, internal controls, and security, and must segregate client virtual-currency assets from the institution's own assets, mirroring the protective architecture used in traditional brokerage custody.
-
Why is bank custody of crypto considered a market milestone?
Regulated-bank custody gives institutional balance sheets — pensions, endowments, RIAs — a familiar venue to hold spot Bitcoin and Ethereum, removing the need to rely on self-custody or offshore providers and turning crypto exposure into a balance-sheet-eligible asset class.
-
What should investors watch once the law takes effect on Aug. 1?
The Minnesota Commissioner of Commerce's 60-day notice docket is the key signal: filings there will name the first wave of state-chartered banks and credit unions entering the market, and the order they file will show how quickly the policy converts into actual client custody accounts.
