The banking industry's long-running standoff with the crypto sector has moved into the courtroom. On October 2, 2026, the Independent Community Bankers of America (ICBA), an advocacy group representing community banks, filed a lawsuit against the Office of the Comptroller of the Currency (OCC) in the US District Court for the District of Columbia. The target is an OCC rule that allows companies performing non-fiduciary work, including digital asset activities, to obtain national trust bank charters.

The OCC is the Treasury Department bureau responsible for chartering, regulating, and supervising national banks, and its trust charters have historically been tied to fiduciary duties — legal obligations requiring institutions to act in their clients' best interests.

What the Lawsuit Challenges

The rule at the center of the dispute is a final rule the OCC issued on March 2, 2026. It created a pathway to national trust bank charters for entities whose business is not strictly fiduciary in nature.

The OCC's rule widened the lane to include non-fiduciary custody arrangements. Under the new framework, holding assets for safekeeping without assuming the broader fiduciary role now qualifies under the same charter umbrella. Custody — the safekeeping of customers' digital assets — is a foundational service in the digital asset industry.

ICBA argues the rule exceeds what the National Bank Act allows. The National Bank Act is the federal statute that governs national banks and provides the OCC its chartering authority. In the group's view, the OCC effectively rewrote its own job description without authorization from Congress.

The complaint also contends the new charters let firms skip obligations that apply to traditional banks. ICBA specifically points to the Community Reinvestment Act (CRA), a federal law requiring banks to help meet the credit needs of the communities they serve, and FDIC insurance, which protects customer deposits against bank failures.

A substantial portion of the complaint focuses on risk. ICBA objects to allowing companies engaged in what it calls high-risk digital asset activities to operate under lighter standards than those imposed on conventional banking institutions. The group further argues that uninsured entities could use these charters to sidestep state consumer protections.

ICBA Leadership Weighs In

ICBA President and CEO Rebeca Romero Rainey said the national trust charter was never intended to be a “side door” for digital asset companies. She also argued that these firms often lack the federal consumer protections the public associates with traditional banks.

A Fight That Started Well Before the Filing

The lawsuit did not arrive out of nowhere. ICBA has opposed a series of charter applications from crypto firms dating back to at least 2025. Among the names on that list are Coinbase National Trust and Ripple. The group's complaint takes aim at the charter framework these and similar firms have pursued.

What This Means for Crypto Firms and the OCC

The most immediate stakes fall on digital asset companies that see a federal trust charter as a path to mainstream credibility. A national charter can offer a single federal framework rather than a patchwork of state rules.

Community banks are arguing about consumer protection and legal authority, but a federal charter for a crypto custodian would also mean a new kind of rival operating under a different rulebook. Traditional banks carry CRA and FDIC obligations, and ICBA's case essentially asks why newcomers should receive similar standing without them.

The OCC now has to defend a rule it finalized on March 2, 2026 as squarely within its statutory powers.

What to Watch Next

Key items ahead include the OCC's formal response in the District of Columbia court, any request to pause the rule while the case proceeds, and whether other banking groups or crypto firms join the fight on either side. Pending charter applications from digital asset companies will also be worth tracking, since their fate may now hinge on how a judge reads the National Bank Act.
