Minnesota Authorises Banks and Credit Unions to Custody Crypto, Effective August 1
Minnesota Governor Tim Walz signed HF 3709 into law on May 17, 2026, giving the state's commercial banks and credit unions explicit legal authority to hold cryptocurrency on behalf of customers. The law takes effect August 1 and covers 240 commercial insured state-chartered banks holding roughly $128 billion in combined assets, plus 82 credit unions.
The legislation passed with near-unanimous support. The House voted 130 to 4 in favour on April 30, the Senate approved it 51 to 16 on May 6, and the House passed a concurrence vote of 119 to 6 on May 11. Before launching custody services, institutions must notify the Minnesota Department of Commerce at least 60 days in advance.
Under the law, banks may act in either a fiduciary or non-fiduciary capacity as custodians, meaning they can hold assets either as a legal trustee or simply as a safekeeping provider. Credit unions are limited to the non-fiduciary role only. Regardless of structure, all institutions face a firm restriction: they cannot trade, invest in, or lend out any crypto assets held in custody. Customer holdings must be legally and operationally segregated from the institution's own balance sheet.
Banks may also contract third-party service providers or subcustodians to handle the technical side of custody. That provision opens a commercial lane for institutional-grade crypto custody infrastructure providers. Firms such as BitGo and Fireblocks are already active in this market, though no such providers have been specifically named in connection with HF 3709 by primary news sources covering the legislation.
Representative Bernie Perryman, who sponsored the bill, framed the law as a matter of consumer protection as much as financial innovation. "Minnesota-based financial institutions are allowed to evolve alongside their customers and members rather than forcing Minnesotans to rely on unregulated, out-of-state or offshore providers for services," Perryman said.
Minneapolis is home to U.S. Bancorp, the seventh-largest bank in the United States by assets. That institutional presence means the law carries potential relevance beyond the regional level, though U.S. Bancorp has not issued a public statement on HF 3709.
The law arrives at a significant moment in digital asset regulation. Throughout 2025, the Office of the Comptroller of the Currency issued a series of interpretive letters confirming that nationally chartered banks and federal savings associations could already provide crypto custody, execute client-directed trades, and outsource permissible crypto activities to third parties, all without seeking prior OCC supervisory non-objection (the formal process the OCC previously required before institutions could undertake such activities). Minnesota's law now extends comparable clarity to state-chartered institutions and, importantly, to credit unions. Federal OCC guidance did not address credit unions, since the OCC's jurisdiction covers only the institutions it charters rather than state-chartered cooperatives, and no NCUA guidance has been identified as filling that gap.
Minnesota is not acting in isolation. Wyoming pioneered the Special Purpose Depository Institution model for digital asset banking, and states including Texas, Florida, and Arizona have also advanced digital asset legislation in recent years. Minnesota's near-unanimous legislative vote underscores how thoroughly crypto custody has become a bipartisan, low-controversy question in U.S. financial regulation.
At the federal level, the GENIUS Act, a law establishing a federal stablecoin licensing framework, is now prompting downstream agency rulemaking, with the first issuer applications expected around July 2026.
Twelve days before signing HF 3709, Governor Walz signed a companion bill, SF 3868, on May 5, 2026. SF 3868 bans crypto ATMs (automated teller machines for buying and selling cryptocurrency) statewide, targeting elder fraud. Although the two bills reached the governor's desk at different times, they reflect a consistent regulatory posture that the legislature developed in tandem: expanding tightly governed institutional access while closing down loosely regulated consumer-facing channels.
For observers outside the United States, the contrast with other regulatory environments is instructive.
Africa's crypto adoption grew 52 percent year-over-year according to Blockonomi's 2026 tracking data, yet bank-level custody authority remains largely uncodified across the continent. South Africa's Absa Bank has partnered with Ripple on institutional crypto custody infrastructure, but that arrangement rests on a private contract rather than explicit statutory authorisation. Kenya enacted digital asset oversight legislation in October 2025, and Mauritius has maintained its VAITOS framework since 2021, but neither jurisdiction has extended formal custody rights to cooperative financial institutions such as savings and credit cooperatives, known as SACCOs. Minnesota's credit union provisions offer a workable legislative model for African nations where cooperative finance reaches populations that commercial banks do not.
In South Asia, the picture is starker. Indian banks remain prohibited from directly holding or investing in cryptocurrencies under Reserve Bank of India guidelines. India's crypto policy discussion paper has been deferred at least five times in under two years, and the RBI has continued to resist any statutory framework that would bring crypto custody into the banking system. For advocates in India and the broader South Asian region pushing for domestic reform, Minnesota's 130 to 4 House vote is a useful data point: where crypto custody has been put to a legislative vote in a mature regulatory market, it has proved to be a bipartisan, low-controversy issue.
The 60-day pre-launch notice window built into Minnesota's law will be the next thing to watch. That reporting period, which begins when institutions notify the Commerce Department, is when technical standards and compliance expectations will likely be operationalised. Custody infrastructure providers and compliance tooling developers have a narrow early-mover window before the first Minnesota institutions go live from August 2026 onward.
