A new application and a legal challenge
Modern Treasury announced on October 5 that it had applied to the Office of the Comptroller of the Currency (OCC) for a limited-purpose national trust bank. Three days earlier, the Independent Community Bankers of America (ICBA) said it had sued the OCC over its trust-bank chartering rule and related guidance. The company announcement is an application, and the association’s announcement describes its lawsuit and requested relief; neither establishes an operating bank or a court decision. Sources: 1, 2
What changed
The charter debate now has two visible tracks: companies seeking permission to run particular banking services, and community banks contesting the legal basis for some trust charters. Modern Treasury’s proposed bank would hold digital assets and provide related conventional-money services. ICBA’s challenge concerns the OCC’s wider approach, including its conditional approval of Protego, rather than a reported ruling on Modern Treasury’s application. Sources: 1, 2
Essential context
A payments company proposes a separate bank
Modern Treasury already provides payments software and services. It says the proposed Modern Treasury National Trust Bank would add digital-asset custody: holding assets for customers. The company says the bank would not make loans or issue stablecoins, and its existing software and payment-service-provider businesses would continue separately. Approval and final authorization to open would still be needed. Sources: 1
What the regulator says it can authorize
The OCC charters and supervises national banks. Its February 27 bulletin describes a final rule covering banks limited to trust-company operations and related activities. The agency says those operations can include non-fiduciary activities alongside fiduciary ones. In plain language, the dispute concerns which services a trust bank may provide beyond acting in a fiduciary role for a client. The OCC presents the change as a clarification of existing authority, rather than an expansion. Sources: 3
The plain-language explanation summarizes the distinction; it does not decide the legal dispute.Why community banks went to court
ICBA argues that the OCC has gone beyond the powers Congress gave it and is allowing crypto-focused firms to compete under a different regulatory framework from insured community banks. Its October 2 statement says the lawsuit asks a federal court in Washington, D.C., to find the final rule and Interpretive Letter 1176 unlawful and to set aside Protego’s conditional charter approval. Those are the trade group’s arguments and requests, not findings adopted by a judge. Sources: 2
The word “bank” does not settle the question
A limited-purpose trust charter describes a restricted set of activities; Modern Treasury’s proposal explicitly excludes lending and stablecoin issuance. The story is therefore about permission to provide particular services, not an announcement of a new all-purpose retail bank. ICBA’s challenge also raises questions about the protections customers associate with a federal charter. Whether a product has deposit insurance cannot be inferred from the word “bank” alone.

- Agency bulletin on final rule
OCC explains its final chartering rule
The agency’s bulletin says the rule clarifies national trust banks’ ability to carry out non-fiduciary as well as fiduciary activities, within trust-company operations and related activities. It gives April 1 as the effective date. Sources: 3
- Stated rule effective date
Effective date specified by the OCC
This is the effective date stated in the February bulletin. It is distinct from the later lawsuit and does not show how that challenge will be resolved. Sources: 3
- Lawsuit announced by plaintiff
ICBA announces its lawsuit
The community-bank trade group says it filed in the U.S. District Court for the District of Columbia. Its challenge targets the rule, related interpretive guidance and Protego’s conditional approval. Sources: 2
- Company-reported application
Modern Treasury announces a trust-bank application
The payments company says it submitted an application for a separate national trust bank focused on digital-asset custody and related fiat services. The announcement does not report OCC approval or authorization to operate. Sources: 1
What remains unresolved
Will Modern Treasury receive approval, and on what terms?
The company’s announcement supplies no approval timetable. An OCC decision and any authorization to open would provide evidence beyond the application announcement. Sources: 1
How will the court resolve ICBA’s challenge?
The cited ICBA statement establishes what the plaintiff says it filed and seeks. It does not establish a ruling, a stay or the eventual outcome. This page has not independently reviewed the court docket. Sources: 2
Which services and safeguards will each charter actually cover?
The OCC describes trust-company operations as broader than fiduciary activities alone; ICBA disputes the agency’s legal position. Individual charter decisions and the court’s treatment of that authority will matter to the services firms can offer and the obligations attached to them. Sources: 3, 2
