The U.S. Office of the Comptroller of the Currency (OCC) has issued Interpretive Letter 1184, formally authorizing national banks and federal savings associations to buy and sell cryptocurrencies on behalf of their customers, as long as the assets are held in custody.
This decision, published on May 7, 2025, dramatically shifts the tone of federal oversight and marks the strongest institutional backing for crypto markets to date.
“Banks are now free to participate directly in crypto asset markets,” stated OCC Acting Comptroller Marcus Lee. “This change reflects the evolution of customer demand and the digital transformation of finance.”
What Does Interpretive Letter 1184 Say?
Interpretive Letter 1184 removes the previous restriction that required prior approval for federally chartered banks to engage in digital asset activities. The new framework:
-
Authorizes buying and selling of crypto assets held in custody
-
Permits outsourcing of custody and execution services to vetted third-party providers
-
Requires full compliance with risk management, AML/KYC, and operational safety guidelines
-
Emphasizes adherence to existing banking regulations while engaging in crypto markets
According to the OCC’s official release, all activities must be conducted in a “safe, sound, and lawful manner,” ensuring that the integration of digital assets aligns with broader financial system protections.
Why This Is a Game-Changer for Crypto and Banking
This OCC ruling has major implications for both traditional finance and the crypto industry:
-
Bridges Wall Street and Web3
National banks can now directly facilitate crypto trading for clients — from high-net-worth individuals to retail investors — without needing separate approvals. -
Boosts Institutional Legitimacy
With regulatory clarity, financial institutions may now begin building crypto product offerings, including tokenized asset portfolios and digital custody accounts. -
Expands Crypto Market Liquidity
Banks entering the crypto market can dramatically increase trading volume, custody coverage, and liquidity for top digital assets like Bitcoin, Ethereum, and stablecoins. -
Encourages Custody Innovation
The guidance permits banks to partner with crypto-native custodians, such as Anchorage, Coinbase Custody, or BitGo, expanding integration opportunities across the sector.
Industry Reactions: Bulls Take Note
Crypto markets responded positively to the OCC’s decision, with major digital assets posting modest gains in the hours following the announcement.
“This is the most important regulatory shift since OCC’s 2020 custody guidance,” said Meltem Demirors, Chief Strategy Officer at CoinShares. “We’re now witnessing the gradual normalization of crypto within traditional financial infrastructure.”
JPMorgan, BNY Mellon, and Citibank — all of which already offer digital asset custody or research divisions — are expected to expand their crypto capabilities following this new interpretive guidance.
Legal and Compliance Considerations OCC
While the OCC’s letter offers clarity, banks are still required to:
-
Maintain internal controls and anti-money laundering systems
-
Follow strict customer verification (KYC) procedures
-
Assess cybersecurity, market risk, and vendor resilience
-
Report crypto-related activity within the scope of federal and state laws
Legal experts anticipate that OCC’s move will influence other agencies, including the FDIC and SEC, to provide similar or complementary guidelines, particularly around tokenized securities and stablecoin classifications.
Broader Impact on U.S. Crypto Regulation
This ruling comes amid rising global competition for crypto leadership. In contrast to the U.S. SEC’s more enforcement-heavy approach, the OCC’s move signals a shift toward proactive integration, aligning with broader federal goals to modernize financial infrastructure.
“The OCC just opened the door for real digital asset banking in America,” tweeted Caitlin Long, founder of Custodia Bank. “Now it’s time for Congress to catch up.”
What Comes Next?
Following this decision, industry observers are watching for:
-
Expansion of crypto trading desks at major U.S. banks
-
ETF product launches tied to bank-led custody systems
-
Cross-border custody partnerships between U.S. and EU banks
-
Clarification from other federal regulators on token issuance, DeFi, and staking
This is widely expected to accelerate the mainstream adoption of crypto financial products, particularly for institutions that were previously held back by legal uncertainty.
Conclusion: A Turning Point for U.S. Crypto Banking
The OCC’s Interpretive Letter 1184 marks a defining moment in converging traditional finance and digital assets. By enabling U.S. banks to buy and sell cryptocurrencies held in custody, regulators have clearly intended to modernize the financial system and embrace blockchain-powered innovation.
As this policy paves the way for deeper institutional participation, the lines between legacy banking and decentralized finance continue to blur. For investors, institutions, and crypto-native companies alike, this ruling is more than regulatory clarity — it’s an open invitation to shape the future of digital finance.
