ICBA sues OCC over crypto trust charters granted to Coinbase, Circle

The Independent Community Bankers of America (ICBA) filed suit against the Office of the Comptroller of the Currency on October 2 in the U.S. District Court for the District of Columbia, challenging an OCC rule finalized earlier this year that widened the agency's authority to issue national trust bank charters to firms whose business is primarily digital assets. The complaint names Coinbase's and Circle's previously approved trust charters as the kind of grant Congress never authorized.

What happened

ICBA's complaint targets the OCC rule finalized on March 2, 2026 that permits entities engaged in non-fiduciary work — including digital asset custody, stablecoin issuance and tokenization services — to apply for and receive a national trust bank charter. The trade group argues the OCC exceeded its statutory authority under the National Bank Act, which, in ICBA's reading, authorizes trust charters only for institutions whose core activity is fiduciary. The suit asks the court to vacate the rule and, with it, the derivative approvals that have flowed from it to crypto applicants.

ICBA president Rebeca Romero Rainey framed the filing in a statement: "The national trust charter was never intended to be a 'side door' for digital asset companies." The group had already written to the OCC in opposition to Coinbase's trust charter application and to subsequent crypto applications. The lawsuit converts that administrative advocacy into a judicial challenge to the enabling rule.

Mechanism

A national trust bank charter is a federal banking license, but it is narrower than a full-service national bank charter: trust banks hold assets in a fiduciary capacity and are not insured by the FDIC, do not take ordinary demand deposits, and are not subject to the Community Reinvestment Act (CRA). Under the pre-2026 reading, that charter was reserved for institutions whose business was fiduciary — classic trust and custody, personal trust administration, employee-benefit plan trusteeship. The OCC's March rule extended it to firms whose business lies in digital-asset custody and the issuance and redemption of payment stablecoins — activities ICBA says resemble deposit-taking without the obligations that attach to a deposit-taking charter.

The practical consequence of the rule, which ICBA cites in its complaint, is that a crypto firm with a national trust charter can take customer dollars for stablecoin minting across state lines without obtaining state money-transmitter licenses, without CRA obligations, without FDIC insurance assessments, and under lighter capital and liquidity standards than an insured depository.

Impact

Already-approved charters are the live stakes. The OCC has, under the current administration, approved national trust charters for a Coinbase subsidiary and for a Circle entity, and conditionally approved charters for other crypto applicants. If the court vacates the March rule, those approvals may fall with it; if the court sustains the rule, the pipeline of pending applications — a short list that has included Ripple, Paxos, and Fidelity Digital Assets at various points — gets clearer regulatory footing.

The suit also lands on the OCC and its interpretive posture. The agency's licensing division has approved every crypto trust applicant whose record is in its public docket to date. A judicial ruling that trust charters are statutorily reserved for fiduciary business would compel the OCC to re-paper its posture across the entire crypto chartering pipeline.

What to watch

1. The OCC's response brief, due in roughly 60 days under the court's standard scheduling order, which will set out the agency's statutory defense of the March rule.
2. Whether the court grants ICBA a preliminary injunction halting new trust-charter approvals while the case proceeds — the complaint reads as if a motion will follow.
3. Any intervenor filings from Coinbase, Circle or other charter holders whose approvals are implicated.
4. Reactions from state bank regulators: the Conference of State Bank Supervisors has historically filed in parallel against federal preemption of state licensing, and the deposit-draining argument is a long-standing CSBS theme.

Context

The suit is the second major legal challenge in a month to a federal regulator's expansion of crypto's institutional footprint. On September 29, the SEC proposed a rulemaking under the Investment Advisers Act to let state trust companies serve as qualified custodians for registered investment advisers holding crypto assets — a parallel widening of a federal gateway for crypto custody. ICBA's complaint cites the broader pattern of federal regulators opening their respective "trust" statutes to firms whose business is digital assets, and argues that each such opening lets a crypto company take on bank-like functions without bank-like obligations.
