Custodia Bank has lost another major round in its long-running battle to secure a Federal Reserve master account after the U.S. Court of Appeals for the Tenth Circuit declined to hear the bank’s final appeal. The decision effectively ends a legal fight that has stretched on for roughly five years and centered on whether the Federal Reserve has discretion to deny master account access to eligible institutions.

A Federal Reserve master account provides direct access to the central bank’s payment infrastructure, allowing institutions to settle transactions and hold reserves without relying on intermediary banks. Custodia has argued that federal law entitles qualified state-chartered banks to this access, while regulators have maintained that the Federal Reserve retains authority to evaluate and reject applications based on risk considerations. Multiple courts have now sided with the Fed’s interpretation.

The latest ruling upheld previous decisions that recognized the Federal Reserve’s discretion over master account approvals. According to court filings, the appeals court voted 7-3 against rehearing the case, leaving intact earlier rulings that favored the central bank’s position.

While the outcome represents a significant defeat for Custodia, the case continues to attract attention because of its broader implications for crypto banking in the United States. Supporters of Custodia have argued that denying direct access to Federal Reserve payment rails creates barriers for innovative financial institutions and limits competition within the banking sector. Critics, meanwhile, have emphasized the need for regulators to maintain oversight and manage potential risks associated with novel banking models and digital assets.

One notable aspect of the decision was a dissenting opinion from Judge Timothy Tymkovich, who argued that the issue carries major consequences for the banking industry and questioned whether Reserve Banks should possess such broad discretion over account approvals. The dissent highlighted the ongoing legal and policy debate surrounding access to the nation’s core financial infrastructure.

Despite Custodia’s loss, the broader conversation has not disappeared. Recent developments indicate that regulators are exploring alternative frameworks that could provide limited forms of Federal Reserve access to certain financial institutions. In particular, discussions surrounding so-called “skinny” master accounts or restricted payment accounts have gained attention following the approval of a limited account structure for other crypto-focused entities.

These developments suggest that while Custodia’s specific legal challenge may have reached its conclusion, the underlying question of how digital asset banks and crypto-focused institutions should interact with the Federal Reserve system remains unresolved. Policymakers, regulators, and industry participants continue debating where the balance should be struck between financial innovation and systemic risk management.

The story may not be entirely finished either. Reports indicate that Custodia is continuing to pursue avenues for Federal Reserve access, and recent reports suggest the bank is seeking review by the U.S. Supreme Court. Whether those efforts ultimately succeed remains uncertain, but the dispute has already become one of the most closely watched legal battles involving crypto banking and federal financial infrastructure in the United States.
