The battle for direct access to the US banking system is heating up, and the digital asset industry is rallying behind one of its own. The Blockchain Association has officially urged the US Supreme Court to hear Custodia Bank’s high-stakes challenge against the Federal Reserve. At the heart of this legal showdown is the Fed’s controversial decision to deny Custodia a “master account”—a critical tool that would give the crypto-focused, Wyoming-chartered bank direct access to the central bank’s payment system without needing a traditional middleman.
Custodia first applied for this master account back in 2020. However, the Federal Reserve Bank of Kansas City denied the application in 2023. When the Tenth Circuit Court of Appeals ruled that the Fed had the ultimate discretion to reject the request—and later voted 7-3 against even rehearing the case—it left the Supreme Court as Custodia’s final hope for a reversal.
Why the Blockchain Association is Fighting for Custodia
In a recently filed amicus brief, the Blockchain Association argued that the Federal Reserve shouldn’t have unchecked power to deny eligible state-chartered banks access to its payment services. The industry group points out that federal law explicitly requires the central bank to make these services available to qualifying nonmember banks. By letting the Fed arbitrarily withhold services that are essential for a bank to operate independently, the appeals court’s ruling essentially grants the central bank an unfair veto power over state-chartered institutions.
The association also tied Custodia’s uphill battle to a broader, more troubling trend often referred to within the industry as “Operation Choke Point 2.0.” They argue that federal regulators have been quietly but aggressively discouraging traditional banks from doing business with the digital asset sector. If the Fed is allowed to interpret its authority this broadly, the association warns it could easily shut out other perfectly eligible state-chartered banks simply because they choose to serve the crypto space.
How Other Crypto Companies Are Navigating US Banking
While Custodia fights its battle in the nation’s highest court, other major players in the crypto space are actively carving out their own paths into the traditional US banking system—and some are finding surprising success. In a stark contrast to Custodia’s rejection, Kraken Financial recently secured a limited-purpose master account from the very same Federal Reserve Bank of Kansas City, granting Kraken direct access to Fedwire.
Beyond master accounts, federal charters are becoming an increasingly popular route for crypto integration. The Office of the Comptroller of the Currency (OCC) gave Coinbase conditional approval to establish a national trust company, a move that brings its custody services under federal watch without letting it operate as a full commercial retail bank. Similarly, Circle recently received final OCC approval for its national trust bank, while heavyweights like Ripple, BitGo, Fidelity Digital Assets, and Paxos have all landed conditional nods from regulators.
Unsurprisingly, this aggressive push into traditional finance has sparked pushback from legacy institutions. Traditional banking groups, such as the Independent Community Bankers of America, have strongly opposed approvals for companies like Coinbase. They argue that crypto firms are trying to reap the benefits of being a bank without subjecting themselves to the strict, comprehensive regulatory frameworks that traditional banks must navigate daily. As the Supreme Court weighs whether to take up Custodia’s landmark case, the final decision could permanently reshape how digital asset companies interact with the US financial system.
