Custodia Takes Federal Reserve Battle to U.S. Supreme Court, Seeks Landmark Ruling on Banking Access
Custodia Bank has petitioned the U.S. Supreme Court to hear its long-running legal challenge against the Federal Reserve over the denial of a Federal Reserve master account—a decision the Wyoming-based digital asset bank says has effectively prevented it from operating on equal terms with other regulated financial institutions. The petition marks the latest chapter in a legal battle that has lasted nearly six years and could have far-reaching implications for banking regulation and the cryptocurrency industry.
A Federal Reserve master account allows banks to access the Fed’s payment system directly, enabling them to settle transactions, hold reserves and conduct interbank payments without relying on correspondent banks. Custodia argues that denying such access has placed it at a severe competitive disadvantage, describing the decision as a “death sentence” for its business model.
The dispute began after Custodia—formerly known as Avanti Bank—applied for a master account following its charter as a Wyoming Special Purpose Depository Institution (SPDI), a banking framework created to serve digital asset businesses. In January 2023, the Federal Reserve Bank of Kansas City rejected the application, citing significant safety and soundness concerns arising from Custodia’s crypto-focused operations. Federal district and appellate courts subsequently upheld the Fed’s decision.
In its petition before the Supreme Court, Custodia contends that the Federal Reserve has claimed broader discretionary authority than Congress intended. The bank argues that the case raises an important constitutional question regarding whether regional Federal Reserve Banks possess unchecked power to deny eligible institutions access to the nation’s central payment infrastructure. The petition also points to recent Supreme Court decisions concerning the Federal Reserve’s institutional independence as reinforcing the need for judicial clarification.
The Federal Reserve has consistently maintained that it has the statutory authority to evaluate whether granting a master account would pose risks to the banking system. Regulators have expressed concerns that institutions primarily engaged in crypto-related activities may present heightened operational, liquidity and financial stability risks, justifying closer scrutiny before granting direct access to the Fed’s payment network.
The outcome of the case could extend well beyond Custodia. A Supreme Court ruling clarifying the scope of the Federal Reserve’s discretion would influence how future fintech firms, digital asset banks and other non-traditional financial institutions gain access to the U.S. payments system. It may also shape the balance between federal regulatory oversight and state-chartered banking innovation.
The U.S. Supreme Court has not yet decided whether it will hear the appeal. If the justices grant review, the case could become one of the most consequential banking and financial regulation disputes in recent years, addressing fundamental questions about access to America’s central banking infrastructure in the era of digital finance.
