The OCC Opens the Door for Banks and Crypto
The Office of the Comptroller of the Currency has ruled that national banks can provide custody services for crypto assets. This is not a minor regulatory update — it is the beginning of crypto's integration into the traditional banking system.
The OCC Opens the Door for Banks and Crypto
The Office of the Comptroller of the Currency — the federal agency that charters and regulates national banks — has issued an interpretive letter confirming that national banks and federal savings associations may provide cryptocurrency custody services to their customers. The letter, issued by Acting Comptroller Brian Brooks, clarifies that custody of crypto assets is a modern form of traditional banking activity and falls within the existing authority of national banks.
This is not a minor regulatory update. It is a structural change in how crypto interacts with the traditional financial system.
What This Means
Until now, crypto custody has been provided by specialised firms — Coinbase Custody, BitGo, Anchorage, Fidelity Digital Assets — that operate under state-level money transmitter licences or trust company charters. National banks, which serve the vast majority of institutional and retail customers in the United States, have been on the sidelines — uncertain about their authority to hold digital assets and unwilling to take regulatory risk.
The OCC's letter removes that uncertainty. National banks can now offer crypto custody as part of their existing service offerings, using their existing infrastructure, compliance frameworks, and customer relationships. A bank that already provides custody for stocks, bonds, and other financial assets can now add crypto to that list without seeking additional regulatory approval.
The implications cascade. If banks can custody crypto, they can offer crypto-related services — trading, lending, and portfolio management — to their existing customers. Institutional clients that require their assets to be held by a qualified custodian now have a much broader set of options. And the integration of crypto into the banking system creates distribution channels that specialised crypto firms cannot match.
The Bigger Picture
The OCC under Brian Brooks — a former Coinbase executive — has been systematically opening doors between crypto and traditional banking. The custody letter is one of several actions: the OCC has also clarified that banks can hold stablecoin reserves, provide banking services to crypto companies, and participate in blockchain-based payment networks.
Taken together, these actions represent a deliberate strategy to integrate crypto into the regulated banking system rather than keeping it at arm's length. The philosophy is that crypto is better regulated within the banking system — where the OCC has oversight, examination authority, and enforcement tools — than outside it, where it operates in a regulatory grey area.
My View
The OCC's actions are the most consequential regulatory development for crypto in the United States since the SEC's token framework. They do not make crypto legal or illegal — it was already legal. They make it normal — part of the standard service offering of the institutions that serve hundreds of millions of Americans.
This normalisation is what drives adoption at scale. Not ideology. Not technology. Not price appreciation. But the quiet integration of crypto into the systems that people already use and trust. When your bank offers Bitcoin custody alongside your brokerage account, the barrier to participation drops to near zero.
The most important regulatory changes are not the ones that make headlines. They are the ones that make crypto boring — that integrate it into the existing financial system so seamlessly that using it requires no more effort than using any other financial service.
