Blockchain Association Backs Custodia Bank In Supreme Court Fed Master Account Fight

“This is not just about Custodia,” said Terrett in a statement. “It’s about whether the Federal Reserve can unilaterally decide who gets to participate in the banking system. That has implications for innovation, competition, and due process.”

The amicus brief aligns with the Blockchain Association’s broader mission to advocate for clear and fair regulatory treatment of digital assets. The group has previously filed comments on various regulatory proposals and has supported litigation that challenges what it sees as overreach by federal agencies.

Why This Case Matters for the Crypto Industry and Beyond

The outcome of this case could set a precedent for how state-chartered banks—especially those serving crypto businesses—gain access to the Federal Reserve system. If the Supreme Court agrees to hear the case, it could clarify the legal standards for master account access, providing certainty for banks that want to offer digital asset services.

Beyond crypto, the case raises fundamental questions about the separation of powers and the limits of central bank authority. A ruling in favor of Custodia could limit the Fed’s ability to use its discretion to exclude legally qualified institutions, while a ruling for the Fed could reinforce its broad authority.

Industry observers note that the Supreme Court has shown increasing interest in cases involving administrative law and agency authority. This case fits that pattern, as it challenges the decision-making process of a quasi-governmental entity.

What’s Next?

The Supreme Court has not yet decided whether to grant certiorari in the case. If it does, oral arguments would likely take place in the 2025–2026 term, with a decision expected by mid-2026. In the meantime, Custodia continues to operate under its state charter, though without a master account it faces limitations on its ability to offer certain services.

Legal experts say the Court’s decision on whether to hear the case could come within the next few months. The Blockchain Association’s amicus brief is one of several that may be filed, reflecting the high stakes for the financial industry.

Conclusion

The Blockchain Association’s support for Custodia Bank underscores the importance of the case for the crypto industry and for the broader financial system. The central question—whether regional Federal Reserve banks can independently deny master accounts to qualified state-chartered banks—has implications for regulatory consistency, innovation, and the limits of central bank power. As the Supreme Court weighs whether to take up the case, the industry will be watching closely.
