Custodia Bank, a pioneering Wyoming-based crypto bank, has officially filed a certiorari petition with the U.S. Supreme Court, escalating a legal battle that could redefine access to the nation’s payment systems for state-chartered financial institutions. The petition, submitted on July 10, 2026, directly questions whether regional Federal Reserve Banks possess the unilateral discretion to deny master accounts to eligible state-chartered banks—a critical gateway for settling payments directly through the Federal Reserve’s rails.
The case stems from the Kansas City Fed’s 2023 rejection of Custodia’s master account application, citing risks associated with its crypto-focused business model. Custodia, which holds a Wyoming special purpose depository institution (SPDI) charter, argues that the denial undermines the dual banking system and effectively forces innovative banks into dependency on intermediary institutions. By taking the dispute to the highest court, Custodia is challenging the interpretation of the Monetary Control Act of 1980, which lower courts—a Wyoming district court and a divided Tenth Circuit panel—previously interpreted as granting the Fed broad, discretionary authority over account access.
The bank’s legal team, including powerhouse firm Davis Polk, contends that the Fed’s position disrupts the balance of state and federal banking powers. Their petition warns that “the case may affect other banks with new business models” and raises constitutional questions about the scope of authority wielded by Federal Reserve Bank presidents. Without a master account, crypto-native banks must rely on partner banks for settlement, limiting their ability to offer seamless services and potentially hampering broader crypto adoption.
The Supreme Court has not yet decided whether to hear the case, but the filing places crypto banking access squarely before national legal and policy observers. If the justices take up the matter, the eventual ruling could establish precedent on how federal banking laws apply to digital asset firms. This development arrives amid a wider debate over crypto banking regulations, with institutions and state regulators closely tracking the outcome.
