Custodia Bank Appeals to U.S. Supreme Court to Challenge Federal Reserve's Control Over Banking Access
Custodia Bank calls on the U.S. Supreme Court to challenge the Federal Reserve’s authority over master accounts and promote financial innovation.

Custodia Bank Seeks Supreme Court Review
Custodia Bank has recently filed a reply brief requesting that the U.S. Supreme Court review a decision made by the 10th Circuit Court of Appeals. This legal move comes after the appellate court upheld the authority of regional Federal Reserve banks to deny master accounts to banks deemed eligible. The crypto-centric Custodia Bank argues that intervention by the Supreme Court is essential to address what it describes as the Federal Reserve’s oppressive influence on financial innovation.
Implications of the Appellate Ruling
In its brief, the bank highlights the implications of the appellate ruling, which it claims gives undue power to unelected regional bank presidents to potentially sabotage "disfavored" banks' access to vital payment systems. Custodia warns that if the ruling remains unchanged, it could gravely impact the nation's dual banking framework and restrict states' abilities to promote financial innovation.
Legal Arguments and Interpretations
The legal argument rests on the interpretation of the 1980 Monetary Control Act, which Custodia insists obligates the Federal Reserve to provide payment services to qualified banks, without allowing for arbitrary policy-based rejections. The Federal Reserve contends that the act only emphasizes that payment services should be available to nonmember depository institutions as a category, not necessarily to all individual applicants. In response, Custodia argues that any depository institution eligible for FDIC insurance qualifies for these services under the Act's definitions.
Background of the Dispute
The dispute initially surfaced in 2022, when Custodia accused the Federal Reserve Bank of Kansas City of delaying its master account application. After a formal rejection in early 2023—citing concerns about Custodia's risk management regarding cryptocurrency—the bank escalated its legal challenge. A federal judge sided with the Fed, a decision that was upheld by the 10th Circuit Court, though with a split on the appellate panel. Dissenting Judge Timothy M. Tymkovich expressed concern that the ruling effectively granted the Federal Reserve unchecked power over state banking decisions.
Support and Broader Implications
Custodia’s legal battle has rallied support from notable figures, including former U.S. Senator Pat Toomey and current Senator Cynthia Lummis, who submitted an amicus brief arguing that the 10th Circuit misunderstood congressional intent regarding agency discretion. The stakes are high: the prevailing legal interpretation risks creating a chilling effect on both the independence of state-chartered banks and the broader landscape of financial innovation in the United States.
