The OCC issued a new notice on May 7, 2025, allowing national banks and federal savings associations to buy and sell cryptocurrencies at the request of customers. Not only that, but they can also outsource the storage and trading of cryptocurrencies to other companies, as long as proper risk management is in place. This regulation is detailed in interpretation letter 1184, which supplements the earlier interpretation letter 1170, which already allowed banks to store cryptocurrencies on behalf of customers. In simple terms, the OCC believes that cryptocurrency storage is akin to traditional custodial services offered by banks; banks can collaborate with third parties but must supervise them diligently.
