The Independent Community Bankers of America sued the Office of the Comptroller of the Currency in federal court in Washington on Oct. 2, asking a judge to vacate the agency's national trust bank rule and Interpretive Letter 1176. The suit lands two weeks after the OCC approved Agora National Trust Bank, Catena Trust Bank and Bastion Platforms, and it attacks the legal foundation for a chartering run the trade group counts at 21 trust banks, 13 of them tied to crypto. Where a company-by-company objection asks the agency to deny one applicant, this suit asks a judge to decide the scope of authority behind every charter that relies on the rule.
Why it matters
The OCC finalized the rule in February, effective April 1, replacing the narrower "fiduciary activities" phrase with the statute's broader wording, "the operations of a trust company and activities related thereto." The agency argues national trust banks have long performed some nonfiduciary work, including custody, and cites 12 U.S.C. 24(Seventh) as authority. The ICBA reads the same rule as stretching a limited-purpose trust charter over non-depository, non-fiduciary crypto businesses under a lighter framework than insured banks face.
The OCC invited this fight. In the February rule it cited the Supreme Court's Loper Bright decision, saying courts must exercise independent judgment when a party with standing disputes whether the National Bank Act authorizes a trust charter. Exposure is uneven: plain fiduciary custody sits furthest from the dispute, while stablecoin issuance, reserves, payments, settlement, conversion and execution sit nearest to it.
Market impact
If the court sides with the OCC, the national trust bank becomes a firmer federal route for crypto custody and stablecoin infrastructure. Forecasts in the suit's orbit run from JPMorgan's $500 billion by 2028 to Coinbase's $1.2 trillion and Standard Chartered's $2 trillion, with Citi's 2030 bull case at $4 trillion. Against the roughly $20.7 trillion US banks held in deposits in the second quarter, that spans 2.4% to 9.7% of the base.
