The Constitution never says the words payment rails. It never defines a master account. And it certainly never anticipates a Wyoming-chartered bank built around digital assets asking for a key to the Federal Reserve’s payment system.
But here we are, with a dispute that looks technical on the surface and structural underneath: who gets to decide which legally chartered banks can access the Federal Reserve’s payment system directly, and whether that decision is discretion or duty.

What a Fed master account is
A Federal Reserve master account is not a badge of prestige. It is infrastructure. It allows a bank to settle payments through the central bank without routing those transactions through another financial institution.
In plain terms, it is direct connectivity to the system that moves money between banks. Without it, a bank can still operate, but it may have to rely on an intermediary and may face added cost, delay, or operational dependency.
The bank at the center
Custodia Bank is a Wyoming-chartered special-purpose depository institution (often shortened to SPDI) that has described its business as focused on digital-asset custody and payments and settlement services, including stablecoin-related products aimed at institutional clients.
Custodia has spent years pursuing a master account. That long campaign matters because it frames the stakes as bigger than one application. If access can be withheld even from an entity that is legally eligible, then eligibility can start to look less like a status and more like a starting point.
The denial and the 10th Circuit
The Federal Reserve Bank of Kansas City rejected Custodia’s application after determining that the bank’s crypto-focused business model posed undue risks to the banking system.
In October 2025, the U.S. Court of Appeals for the 10th Circuit upheld that denial in a divided decision. The majority treated master-account access as something Federal Reserve banks may grant, not something they must grant, even when the applicant meets statutory eligibility requirements. The court also said accepting Custodia’s position would impair the Fed’s ability to protect the financial system.
Judge David Ebel wrote for the 2-1 majority: “We conclude the plain language of the relevant statutes grants Federal Reserve Banks discretion to reject master account access requests from eligible entities.”
The dissent and the word “shall”
The dissent, by Judge Timothy Tymkovich, reads the governing language differently. The key fight is over what a statute means when it says services “shall” be available to certain eligible institutions. “Shall” can be a command. It can also be interpreted in context as leaving room for judgment calls.
Here, supporters of Custodia want the Supreme Court to treat “shall” as a mandate. If a bank is eligible under the statute, the argument goes, the Fed cannot turn the application into an open-ended policy referendum on which lawful lines of business should have direct access.
The amicus brief behind the push
The Blockchain Association, a cryptocurrency industry trade group, urged the Supreme Court to take up Custodia’s petition in an amicus brief. Its core claim is that the 10th Circuit’s reading gives the Federal Reserve too much room to use payment-system access as leverage, including against lawful digital asset businesses.
“The decision ratifies the Fed’s misuse of its payment services to further an impermissible policy goal—debanking the digital asset industry,” the association said in its brief.
Federal power and the dual banking system
This case is filed as a statutory dispute, but it lands in a familiar American fault line: the division of authority between federal and state institutions.
The United States has long operated under a dual banking system. States charter banks. Federal law and federal regulators shape the rules of the national financial system. Those two tracks are supposed to coexist, not cancel each other out.
The Blockchain Association warned that the 10th Circuit’s approach could give the Fed “veto power over chartering judgments by state regulators.” The practical concern is straightforward. If a state decides a bank can exist, but federal gatekeeping can keep it from direct access to the central payment system, then state authority can become thin in practice.
“Debanking” and why crypto is not the end
In the industry’s telling, this is not only about risk. It is about who can be excluded from essential financial infrastructure, and on what grounds.
Some in the digital-asset world have labeled the broader pattern “Operation Choke Point 2.0,” alleging that federal banking agencies under the previous administration used supervisory pressure to discourage regulated banks from serving digital asset businesses. The association argues that, if master-account access is treated as fully discretionary, that same kind of leverage could extend to state-chartered institutions seeking direct Fed access.
That is why the brief claims the 10th Circuit’s approach “provides a blueprint for federal regulators to debank disfavored industries or companies in the future without interference from state regulators.”
Why “skinny” accounts do not settle it
Federal Reserve officials were already considering specialized “skinny” master accounts that could provide more limited payment system access to crypto and other innovation-focused institutions.
That policy discussion may change how access works in practice, but it does not resolve the legal question Custodia is asking the Supreme Court to decide: whether the statutory scheme creates a right to access for eligible entities, or whether it leaves that decision to Federal Reserve bank discretion.
What happens next
The Supreme Court has not agreed to hear the case. If it does, the justices would not be deciding whether crypto is good or bad. They would be deciding how to read the governing statutes and, indirectly, how much practical power federal institutions can wield over state-chartered banks through control of the payment system.
This is the kind of dispute that rarely captures public attention until its logic migrates. Today it is a crypto bank. Tomorrow it could be any lawful business that depends on ordinary access to the financial system.
Quick FAQ
Is a master account the same as deposit insurance?
No. A master account is about direct access to Federal Reserve payment and settlement services. Deposit insurance is a separate question handled through other legal frameworks.
Did the 10th Circuit say Custodia was ineligible?
No. The majority opinion treated the statutes as allowing Federal Reserve banks to deny access even to eligible entities.
What is the core legal issue?
Whether the relevant federal statutes make Fed payment services available as a mandate for eligible institutions, or whether Federal Reserve banks retain discretion to say no.
