Governor Waller: The Fed Is Studying a 'Skinny' Master Account and Modernizing Fed Rails

Governor Waller: The Fed is studying a 'skinny' master account and modernizing Fed rails, with a focus on private-sector innovation and integration of DLT, stablecoins, and AI.

"As you all know, we are well into a technology-driven revolution in payments, and I am here to say that the Federal Reserve intends to be an active part of that revolution."

Continuation of Deploying New Technologies and Integration with Traditional Rails

Waller clearly states that the Federal Reserve is actively working on modernizing traditional systems to make them ready for stablecoins and other tokenized assets based on distributed ledger technology, as well as the rapid adoption of AI. At the same time, Waller notes that key breakthroughs come from the private sector, and public institutions, including the Fed, must recognize and accept private innovations while maintaining system stability.

Thus, Waller highlights two key aspects of the Federal Reserve: a convener for solving coordination problems and an operator of core payment and settlement infrastructure. Therefore, the regulator is focused on hands-on research into tokenization, smart contracts, and the intersection of AI and payments in order to understand where these technologies actually improve the Fed's payment infrastructure.

'Skinny' Master Account: Managed Access to Fed Payment Services

But one of the main, much more practical points of his statement was the so-called 'skinny' master account. In practical terms, this is a directive to work out a new type of account, which Waller describes as follows:

"To be more concrete, let me describe a possible prototype for this type of payment account or, as I sometimes call it, a 'skinny' master account."

He clarifies the risk controls: Reserve Banks do not pay interest on balances, balance caps are possible, there are no daylight overdraft privileges, and when the balance is zero, payments are rejected. Such an account does not provide access to discount window borrowing or to other services where the Federal Reserve cannot control risk. In essence, this is a legal but risk-limited channel to basic Fed payment services for eligible firms that now more often connect through a third-party bank with a full master account. For fintech, this can reduce integration complexity and review timelines while keeping the regulator's levers of limits and the refusal to pay interest as safeguards.

Overall, Waller gave an interesting metaphor that should say a lot about how the Federal Reserve views the latest technological advances and their impact on traditional financial systems and infrastructure:

"Long before we started speaking of the 'payment rails' that are facilitating the kind of innovation we will be discussing today, the Fed was running trains on steel rails to deliver and clear paper checks traveling across the country. Fedwire began conducting interbank transfers through telegraph wires in the early 20th century. Fast forward to today, where we have multiple infrastructures that settle interbank transfers in real time."

Conclusion

The Federal Reserve sets a relevant, consistent, and large-scale direction: it is testing the compatibility of new technologies with its own payment infrastructure and is already considering managed access to rails through a 'skinny' master account as a prototype. At the same time, the Federal Reserve indicates close cooperation with 100 private-sector innovators, including banks, asset managers, retail payments firms, technology companies, and crypto-native fintechs, which signals that the discussion of new rails goes beyond experiments and includes players whose products already interact with critical infrastructure.
