Custodia Bank Loses Fed Master Account Battle — But the Fight Isn’t Over

Key Highlights

• Custodia Bank has lost its final major court challenge over access to a Federal Reserve master account
• A U.S. appeals court refused to rehear the case en banc, effectively ending Custodia’s legal route in that circuit
• The ruling confirms that Federal Reserve regional banks have broad discretion to deny master account applications
• Custodia argues the decision undermines statutory rights for eligible depository institutions
• The bank is now expected to consider a Supreme Court appeal or alternative access models
• The case has become a landmark dispute over crypto banking access to the U.S. payment system

Custodia Bank has suffered a major legal setback after a U.S. appeals court declined to rehear its case challenging the Federal Reserve’s refusal to grant it a master account. The decision leaves in place an earlier ruling that affirms Federal Reserve Banks have discretion to approve or deny access to the central bank’s payment infrastructure.

The dispute centers on whether Custodia, a Wyoming-chartered crypto-focused bank, is legally entitled to a master account, which would allow it direct access to the Federal Reserve’s payment rails. Without such access, institutions must rely on intermediary banks to process payments and settlements.

The court’s decision reinforces the view that regional Federal Reserve Banks are not obligated to provide master accounts even to institutions that are otherwise legally eligible. This interpretation has been strongly contested by Custodia, which argues that federal law requires the Fed to provide access to eligible depository institutions.

With the rehearing denied, Custodia’s primary legal options in the federal appeals system are now exhausted. The ruling is widely seen as a significant win for the Federal Reserve and traditional banking regulators, who have argued that granting automatic access could introduce financial stability and compliance risks.

However, Custodia has indicated that the fight is not necessarily over. The bank is expected to consider petitioning the U.S. Supreme Court, although the likelihood of review is uncertain. Another possible path is to pursue alternative forms of access through correspondent banking relationships or newly emerging “limited” or “skinny” master account structures.

The case has become one of the most closely watched legal battles in U.S. crypto banking policy, highlighting the tension between innovation in digital asset-focused financial institutions and the Federal Reserve’s cautious approach to granting direct access to its core payment systems.

More broadly, the outcome reinforces a key structural reality in U.S. banking: access to the Federal Reserve remains highly discretionary, and crypto-native banks continue to face significant barriers when attempting to integrate directly into the traditional financial system.
