1. Introduction

The integration of digital assets into the traditional financial system has prompted regulatory bodies to adapt existing frameworks to address emerging challenges. The OCC, as the primary regulator for national banks, has been at the forefront of this adaptation, providing guidance and oversight for institutions engaging in digital asset activities. This report delves into the OCC’s role in regulating digital asset trust banks, focusing on its mandate, the application process for national trust bank charters, regulatory requirements, and the implications for the cryptocurrency industry’s legitimacy.

2. The OCC’s Mandate and Regulatory Framework

2.1 Historical Overview

Established in 1863, the OCC’s primary mission is to ensure the safety and soundness of the national banking system. Over the years, its responsibilities have expanded to include fostering competition, improving supervisory efficiency, and enforcing anti-money laundering laws. The OCC’s jurisdiction encompasses national banks, federal savings associations, and federal branches and agencies of foreign banks.

2.2 Evolution of the OCC’s Approach to Digital Assets

The rise of digital assets, including cryptocurrencies and stablecoins, has introduced new complexities to the financial system. In response, the OCC has issued a series of interpretive letters to clarify the permissibility of certain cryptocurrency activities for national banks. Notably, in 2020, the OCC confirmed that national banks and federal savings associations may provide cryptocurrency custody services for customers, recognizing the importance of digital assets in the modern financial landscape.

In 2021, the OCC further clarified its authority to charter national trust banks, emphasizing that such charters are permissible for banks engaging in trust activities related to digital assets. This clarification aimed to provide a clear regulatory pathway for institutions seeking to offer digital asset services under the federal banking system. (occ.gov)

2.3 Recent Developments

In March 2025, the OCC issued Interpretive Letter 1183, reaffirming that national banks and federal savings associations can engage in specific cryptocurrency activities, such as crypto-asset custody and certain stablecoin activities, without prior regulatory approval. This move signified a more permissive stance toward digital asset activities, aligning with the OCC’s commitment to fostering innovation while maintaining financial stability. (occ.ustreas.gov)

3. The Application Process for National Trust Bank Charters

3.1 Overview of the Application Process

Institutions seeking to operate as national trust banks must submit a comprehensive application to the OCC. This application includes detailed information about the institution’s proposed activities, governance structures, risk management frameworks, and compliance measures. The OCC evaluates these applications to ensure that the proposed operations align with federal banking laws and regulations.

3.2 Key Considerations in the Application Process

The OCC assesses several critical factors during the application process:

Business Plan: A detailed description of the proposed activities, including the scope of digital asset services to be offered.
Risk Management Framework: Policies and procedures to identify, assess, and mitigate risks associated with digital asset operations.
Capital Adequacy: Evidence of sufficient capital to support the proposed activities and absorb potential losses.
Compliance Measures: Systems and controls to ensure adherence to applicable laws and regulations, including anti-money laundering (AML) and know-your-customer (KYC) requirements.

3.3 Case Study: Circle’s Application

In June 2025, Circle, a prominent stablecoin issuer, applied to the OCC for a national trust bank charter, proposing to establish the First National Digital Currency Bank, N.A. This application underscores the growing interest among digital asset firms to operate within the federal banking system. The OCC’s evaluation of such applications involves rigorous scrutiny to ensure that applicants meet all regulatory requirements and can operate in a safe and sound manner. (reuters.com)

4. Regulatory Requirements for Chartered Entities

4.1 Capital Adequacy

Chartered digital asset trust banks must maintain capital levels commensurate with the risks associated with their activities. The OCC evaluates capital adequacy based on the institution’s business plan, risk profile, and potential exposure to market fluctuations.

4.2 Risk Management

Effective risk management is paramount. Institutions must implement robust systems to identify, assess, and mitigate risks related to digital asset transactions, including market, credit, operational, and liquidity risks.

4.3 Compliance with AML/KYC Regulations

Compliance with AML and KYC regulations is mandatory. Chartered entities must establish comprehensive programs to detect and prevent illicit activities, ensuring transparency and integrity in their operations.

4.4 Consumer Protection

Ensuring fair and equal access to financial services is a key mandate of the OCC. Chartered digital asset trust banks must implement measures to protect consumers, including clear disclosures, dispute resolution mechanisms, and safeguards against fraud.
