Crypto bank Custodia Bank has petitioned the U.S. Supreme Court to review its case against the Federal Reserve's denial of access to the payment system. Custodia's application for a master account with the Kansas City Fed was rejected in 2023 due to its focus on crypto-asset activities. The Tenth Circuit Court of Appeals upheld this decision, prompting Custodia to argue that the case questions whether regional Federal Reserve Banks can override state banking charters. Custodia's founder, Caitlin Long, highlighted Wyoming's efforts to foster a crypto-friendly environment, which she claims were dismissed by the Kansas City Fed. The Supreme Court will decide whether to hear the case after its October recess.
