Minnesota Enacts Law Letting State-Chartered Banks Provide Crypto Custody

Minnesota has enacted a new law that expressly authorizes state-chartered banks to provide cryptocurrency custody, giving traditional lenders a clear legal basis to hold digital assets for customers. The measure is codified as Chapter 93 of Minnesota’s 2026 Session Laws and broadens the list of permissible activities for banks operating under a state charter. Under the statute, eligible banks may store, manage, and safeguard cryptocurrencies for both retail and institutional clients. The bill began as HF 3709 in the Minnesota House, drafted by a lawmaker from the St. Cloud area to move bank crypto activity out of a legal gray zone and into a defined regulatory framework. Crypto custody, in practice, centers on the secure storage and administration of the private keys that control access to digital assets. When a bank offers custody, it assumes responsibility for protecting those keys—similar to how banks safeguard deposits or securities held in trust. For customers, bank custody offers an alternative to self-custody wallets or unregulated third-party providers, with the operational controls and oversight typically associated with regulated financial institutions. The change is notable for institutional adoption. For many firms with fiduciary duties—such as pension funds and endowments—allocating to an asset class often requires a qualified custodian. Minnesota’s law reduces uncertainty over whether state-chartered banks can serve that function for crypto. By granting explicit authority, Minnesota also positions its banks to compete with established crypto custodians including Coinbase Custody, BitGo, and Anchorage Digital, as institutional crypto services become a larger revenue contributor across the sector, including for firms tied to Kraken's parent company Payward. Regulated bank custody may appeal to customers wary of keeping assets on exchanges following high-profile failures in recent years. For banks, custody represents a fee-based business line that can generate recurring revenue through storage and administration fees. Compared with lending or trading, custody is generally viewed as lower risk because the bank is not required to take directional market exposure to volatile assets. Operational hurdles remain. Banks seeking to launch custody will need robust key-management infrastructure, such as hardware security modules, multisignature wallet architectures, and disaster-recovery plans. Compliance requirements also need to be mapped to crypto custody, including Bank Secrecy Act obligations, know-your-customer programs, and how state examinations will treat custody operations. While the Minnesota Department of Commerce has consumer-facing crypto guidance, supervisory expectations specific to bank custodians may require further clarification. Insurance is another practical issue. FDIC deposit insurance does not cover cryptocurrency holdings. Banks will need specialized insurance or clear customer disclosures stating that custodied crypto is not protected like dollar deposits. Security standards will be a key benchmark, with institutional-grade providers increasingly emphasizing advanced designs—such as isolated signing and post-quantum approaches—as the baseline for serious custody operations. Minnesota's move adds to a broader state-level push to define how banks can engage with digital assets. Wyoming moved early with special-purpose depository institution charters, and states including Texas and Nebraska have passed crypto-friendly banking laws. The new statute signals that Minnesota lawmakers are framing regulated crypto services as an economic opportunity, which could influence future debates over stablecoins, blockchain-based payments, and tokenized securities. State permission, though, does not displace federal expectations. Banks that are Federal Reserve members or FDIC-insured still must follow federal guidance on crypto-related activities, including recent interagency risk-management statements. How Minnesota regulators coordinate with federal counterparts will shape the law's practical effect. The law arrives amid growing institutional engagement with digital-asset infrastructure. Disclosures by companies such as Bitmine Immersion Technologies about sizable crypto holdings have highlighted the scale of institutional participation that regulated custody could support. Key questions for customers - Can all Minnesota banks offer crypto custody right away? The law applies to state-chartered banks, but launching custody depends on each bank's technology buildout, compliance programs, and risk controls. - What does custody mean for customers? A regulated bank holds and secures the private keys for your digital assets while you retain ownership of the cryptocurrency. - Is custodied crypto insured like deposits? No. FDIC insurance applies to dollar deposits, not cryptocurrency. Any private coverage and its terms should be confirmed directly.
