Minnesota Signs Bill Allowing Banks to Offer Crypto Custody Services

5 mins mins

Minnesota has signed into law a bill that allows state-chartered banks to offer cryptocurrency custody services, creating a formal legal framework for traditional financial institutions to hold digital assets on behalf of customers.

The legislation, codified as Chapter 93 of Minnesota’s 2026 Session Laws, expands the permissible activities of banks operating under state charter. Under the new law, these institutions can store, manage, and safeguard cryptocurrencies for retail and institutional clients.

The bill originated as HF 3709 in the Minnesota House, where a St. Cloud-area lawmaker authored the measure to establish clear rules around how banks interact with digital assets. The goal was to bring cryptocurrency management at banks under a defined regulatory structure rather than leaving it in a legal gray area.

What crypto custody means for Minnesota bank customers

Cryptocurrency custody refers to the secure storage and management of private keys that control access to digital assets. When a bank offers custody services, it takes on the responsibility of safeguarding those keys, much like a traditional bank safeguards deposits or securities in a trust account.

For customers, this means an alternative to self-custody wallets or unregulated third-party custodians. Bank-held custody carries the operational standards, insurance frameworks, and regulatory oversight that traditional financial institutions already maintain for other asset classes.

The distinction matters because custody has been one of the primary barriers preventing institutional capital from entering digital asset markets. Firms with fiduciary obligations, such as pension funds or endowments, typically require a qualified custodian before allocating to any asset class. Minnesota’s law removes ambiguity about whether state-chartered banks can fill that role for crypto.

Why regulated bank custody changes the competitive landscape

By granting explicit legal authority, Minnesota positions its banks to compete with dedicated crypto custodians like Coinbase Custody, BitGo, and Anchorage Digital. This is relevant at a time when firms like Kraken’s parent company Payward have reported growing revenue from institutional crypto services.

Regulated custody also addresses a trust gap. Customers who are uncomfortable holding assets on exchanges, particularly after high-profile collapses in recent years, may prefer the familiarity and perceived stability of a local bank. The bill gives Minnesota banks the legal footing to offer that option.

For banks themselves, custody services represent a new fee-based revenue line. Unlike lending or trading, custody is a lower-risk activity that generates recurring income from storage and management fees without requiring the bank to take on market exposure to volatile assets.

Implementation questions banks still face

A signed bill is not the same as operational readiness. Banks looking to offer custody will need to build or acquire the technical infrastructure for secure key management, including hardware security modules, multi-signature wallet architectures, and disaster recovery protocols.

Compliance is another layer. Banks must determine how cryptocurrency custody interacts with existing Bank Secrecy Act obligations, know-your-customer requirements, and state examination procedures. The Minnesota Department of Commerce already maintains guidance on cryptocurrency for consumers, but supervisory expectations for bank custodians will need further clarification.

Insurance presents a practical challenge as well. Traditional bank deposit insurance through the FDIC does not cover cryptocurrency holdings. Banks will need to secure specialized insurance policies or clearly disclose to customers that custodied crypto assets are not protected in the same way as dollar deposits.

Security standards represent perhaps the most critical operational concern. Companies like Lock.com, which recently entered early access with isolated signing and post-quantum architecture, illustrate the level of technical sophistication that institutional-grade custody demands. Banks entering this space will be measured against those benchmarks.

What Minnesota’s move signals for state-level crypto policy

Minnesota joins a growing number of states that have moved to clarify the relationship between traditional banking and digital assets. Wyoming was an early mover with its special-purpose depository institution charter, and states like Texas and Nebraska have also enacted crypto-friendly banking laws.

The signing of this bill suggests Minnesota’s legislature sees regulated crypto services as an area of economic opportunity rather than purely a consumer protection risk. That framing matters because it could influence how future proposals around stablecoin issuance, blockchain-based payments, or tokenized securities are received in the state.

However, a permissive state law does not override federal regulatory expectations. Banks that are members of the Federal Reserve System or insured by the FDIC must still satisfy federal guidance on crypto activities, including recent interagency statements on risk management. State authority and federal oversight will need to coexist, and how Minnesota regulators coordinate with federal counterparts will shape the practical impact of this law.

The bill also arrives as institutional interest in digital asset infrastructure continues to grow. Companies like Bitmine Immersion Technologies have disclosed significant crypto holdings, underscoring the scale of institutional engagement that regulated custody services could support.

FAQ about Minnesota banks offering cryptocurrency custody services

Can all Minnesota banks immediately offer crypto custody?

The bill applies to state-chartered banks, but offering custody requires building the necessary technical infrastructure, compliance programs, and risk management frameworks. Banks will not launch these services overnight; implementation timelines will vary by institution.

What does cryptocurrency custody mean for customers?

It means a regulated bank holds and protects the private keys to your digital assets. You maintain ownership of the cryptocurrency, but the bank is responsible for securing it against theft, loss, or unauthorized access.

Are custodied crypto assets insured like bank deposits?

No. FDIC insurance covers dollar deposits, not cryptocurrency. Banks offering custody may obtain private insurance policies, but customers should confirm coverage details before using any custody service.

Why does this bill matter for broader crypto adoption?

It removes legal ambiguity for banks that want to serve crypto holders, potentially bringing institutional-grade security and regulatory oversight to an asset class that has largely operated outside the traditional banking system. Broader bank participation could increase trust and accessibility for both retail and institutional users.
