The Independent Community Bankers of America (ICBA) filed a federal lawsuit against the Office of the Comptroller of the Currency (OCC), challenging the agency's authority to grant national trust bank charters to cryptocurrency companies conducting substantial non-fiduciary activities. The Crypto Council for Innovation (CCI) has defended the OCC's approvals and conditional approvals, with CEO Ji Hun Kim calling the suit an effort to resist national trust charters, payments innovation and financial-services competition. ICBA argues that the OCC has enabled crypto firms to obtain federal charter credibility without requirements applied to insured depository institutions, including Community Reinvestment Act obligations, consolidated supervision, capital and liquidity standards, and FDIC insurance. The complaint challenges the OCC's March 2026 National Bank Chartering rule, Interpretive Letter No. 1176 and Protego Holdings Corp.'s conditional charter approval. Existing court filings say the OCC has approved or conditionally approved 21 trust bank charters, including at least 13 tied to digital asset companies. Under US President Donald Trump, approvals or conditional approvals have included World Liberty Financial, Circle, Ripple, Fidelity Digital Assets, BitGo and Paxos, drawing criticism from some lawmakers, particularly over World Liberty Financial's approval.
