The Office of the Comptroller of the Currency (OCC) has taken a significant step in clarifying the regulatory landscape for U.S. banks interested in offering crypto-asset services. In a recent announcement on May 7, 2025, the OCC published Interpretive Letter 1184, which affirms that national banks and federal savings associations have the authority to provide crypto-asset custody and execution services—marking a pivotal moment in the integration of digital assets into traditional banking operations.
This guidance builds upon earlier interpretations, including IL 1170 and IL 1183, reinforcing a consistent regulatory framework that empowers banks to participate in the evolving financial ecosystem while maintaining safety, soundness, and compliance.
What Interpretive Letter 1184 Means for Banks
Under Interpretive Letter 1184, national banks and federal savings associations are explicitly permitted to:
- Buy and sell crypto-assets held in custody, provided these transactions occur at the customer’s direction.
- Outsource permissible crypto-asset activities—such as custody and trade execution—to third-party service providers.
- Operate through sub-custodians, as long as appropriate risk management frameworks are in place.
These permissions are not unconditional. The OCC emphasizes that all activities must be conducted in a safe and sound manner, with strict adherence to applicable laws, regulations, and risk management standards. This includes robust oversight of third-party relationships, cybersecurity protocols, anti-money laundering (AML) compliance, and consumer protection measures.

Building on Previous Regulatory Guidance
The release of IL 1184 does not exist in isolation. It forms part of a growing body of regulatory clarity from the OCC:
- Interpretive Letter 1170 (2020): First established that banks could provide crypto-asset custody services, including holding private keys on behalf of customers.
- Interpretive Letter 1183 (2025): Expanded permissible activities to include participation in independent node verification networks (INVNs), such as blockchain networks, and staking services.
Together, these letters signal a forward-looking approach by the OCC, recognizing that blockchain technology and digital assets are becoming integral components of modern finance. By allowing banks to engage in these services, the regulator supports innovation while ensuring institutional accountability.
Key Implications for the Financial Sector
1. Expanded Role for Traditional Banks
Banks can now act as trusted intermediaries in the digital asset economy. From securely storing crypto-assets to executing trades on behalf of clients, financial institutions are positioned to offer end-to-end solutions that blend traditional banking reliability with cutting-edge technology.
2. Growth of Third-Party Service Ecosystems
With explicit permission to outsource crypto-related functions, banks can partner with specialized fintech firms for custody, execution, or wallet management. However, this comes with heightened responsibility: institutions must implement rigorous due diligence and ongoing monitoring of vendors to mitigate operational and reputational risks.
3. Increased Consumer Confidence
Having regulated banks involved in crypto custody enhances trust among retail and institutional investors alike. Knowing that their digital assets are held by federally supervised entities—with capital requirements, audit trails, and compliance obligations—can encourage broader adoption.
4. Regulatory Alignment Across Agencies
While the OCC governs national banks, other regulators like the Federal Reserve and FDIC also play roles in shaping crypto policy. IL 1184 contributes to a more coherent national framework, potentially paving the way for interagency alignment on digital asset standards.

Frequently Asked Questions (FAQ)
Q: Can all U.S. banks offer crypto custody services?
A: Only national banks and federal savings associations under OCC supervision are directly covered by this guidance. State-chartered banks follow different regulatory paths, often overseen by state banking departments or other federal agencies.
Q: Does this mean banks can invest in cryptocurrency themselves?
A: No. IL 1184 allows banks to execute transactions on behalf of customers based on their instructions. It does not authorize banks to speculate or hold crypto-assets for their own balance sheets unless separately approved.
Q: How does outsourcing affect customer protection?
A: Banks remain fully responsible for outsourced activities. They must ensure third parties meet high standards for security, compliance, and operational resilience. Customers benefit from the bank’s oversight even if services are delegated.
Q: Is there a difference between custody and execution services?
A: Yes. Custody refers to the secure storage of crypto-assets (e.g., managing private keys). Execution involves buying or selling those assets upon customer request. Both are now recognized as permissible bank activities under proper controls.
Q: Are there any restrictions on types of crypto-assets?
A: The OCC does not specify particular tokens or blockchains. However, banks must conduct thorough legal and risk assessments before supporting any asset to ensure compliance with securities, commodities, and AML laws.
