Banking Group Sues OCC Over Crypto Trust Charter Authority, Targeting Protego Approval

The Independent Community Bankers of America filed suit against the Office of the Comptroller of the Currency on October 2, seeking to invalidate the agency's conditional approval of Protego's crypto trust charter and prevent the OCC from issuing further charters under the same legal authority.

The lawsuit goes directly at the question of whether the OCC has statutory power under the National Bank Act to grant trust charters to non-bank crypto entities. The ICBA's complaint targets Protego's conditional approval specifically and asks the court to stop the agency from granting additional charters under its disputed rule and guidance. Protego, a digital asset custody firm, received conditional approval for a national trust bank charter from the OCC, positioning it to offer crypto custody services under a federal framework rather than a patchwork of state licenses.

The ICBA's core argument is jurisdictional. Community banks have long operated under the OCC's regulatory umbrella, and the group contends the agency is now using ambiguous statutory language to extend federally chartered status to a new class of crypto-native firms that would compete directly with traditional institutions without the same deposit-taking obligations, capital requirements, or regulatory history. From the ICBA's perspective, the OCC is effectively creating a lighter-touch federal charter for crypto firms, giving those firms a competitive advantage while sidestepping the legislative process that would normally authorize such a category.

The OCC's counter-position is predictable but not without merit. The agency has historically argued that trust services, including custody of assets on behalf of clients, fall squarely within its mandate, and that crypto assets are simply a modern form of property requiring modern custody solutions. Protego's approval, in that reading, is not a novel expansion of authority but a routine application of existing trust charter rules to a new asset class.

Crypto industry advocates add a second layer: blocking these charters would effectively wall off institutional-grade custody infrastructure behind a state-by-state licensing maze, slowing the kind of regulated custody buildout that the SEC has simultaneously been trying to encourage through its proposed self-custody framework for investment advisers.

This is not the first time a banking trade group has tried to use the courts to police the OCC's jurisdictional ambitions. The Conference of State Bank Supervisors challenged the OCC's fintech charter initiative in 2018, and that litigation dragged through the courts for years before the OCC ultimately withdrew the rule in question. The ICBA's suit follows a similar logic: if you cannot beat a regulator in the comment period, sue over the statutory authority. The outcome here will hinge on how broadly the court reads the National Bank Act's trust provisions, and whether Protego's conditional approval can survive scrutiny as a straightforward trust charter rather than a disguised attempt to create a new charter category.

The stakes extend well beyond Protego. Several other crypto custody firms are understood to be in various stages of the OCC's charter pipeline. A ruling against the OCC would not only unwind Protego's conditional approval but would also effectively shut the door on federal trust charters for crypto firms until Congress acts, which could be years away. That outcome would push institutional custody back toward state trust charters, a slower and more fragmented path. For banks that already offer crypto custody under OCC oversight, the ruling's implications are murkier, though a narrow court interpretation of the agency's authority could create compliance uncertainty across the board.

The lawsuit lands at an awkward moment for U.S. crypto regulation more broadly. Legislators have spent the past two years trying to construct a coherent federal framework for digital assets, and the courts are increasingly being asked to fill gaps that Congress has not yet closed. Whether the ICBA prevails or not, the case is a reminder that the regulatory architecture for crypto custody in the United States remains genuinely unsettled, and that traditional financial institutions intend to contest every inch of the jurisdictional map.
