The Independent Community Bankers of America (ICBA) filed suit Friday in the U.S. District Court for the District of Columbia against the Office of the Comptroller of the Currency (OCC). The complaint, brought under the Administrative Procedure Act, challenges the agency’s authority to charter national trust banks for cryptocurrency companies. ICBA seeks to declare unlawful a March 2, 2026 final rule and Interpretive Letter No. 1176, arguing these measures create a "side door" into the banking system.

ICBA President and CEO Rebeca Romero Rainey stated that such charters allow crypto firms to gain federal credibility without adhering to obligations binding insured depository institutions, including FDIC insurance, capital standards, and the Community Reinvestment Act. The group warned of consumer-protection gaps, noting digital assets held under trust charters lack expected federal protections while preempting state laws. The suit specifically requests vacating Protego Holdings’ conditional charter due to governance shortcomings. This action escalates conflicts as firms like Circle, Ripple, Kraken’s parent, and World Liberty pursue OCC charters.
