The Quiet CBDC Revolution Is Happening Between Banks, Not in Your Wallet

Public debate about central bank digital currencies has focused on the consumer: an app on your phone, a digital banknote, a question about privacy. Meanwhile, a less visible project has been gathering momentum. Central banks in Europe, Switzerland, Asia and elsewhere are working on wholesale digital money, a form of central bank reserves that can settle transactions on the same new ledgers where tokenized bonds, funds and deposits are starting to live. It will never be in anyone's wallet, but it could change how securities markets, cross-border payments and bank funding work.

Why wholesale matters

Banks already hold digital money at central banks. Large payments between them settle in these reserves through real-time gross settlement systems run by central banks. What is changing is the rest of the financial system. Financial institutions are experimenting with tokenization, representing securities and deposits as digital tokens on distributed ledgers that can be transferred and settled nearly instantly and programmed to execute conditional actions. For such transactions to be safe, the cash leg ideally needs to be central bank money on the same or a connected platform. Otherwise, a tokenized bond might be delivered instantly while the payment still moves through legacy systems with a lag, reintroducing the risks tokenization is meant to remove.

The concept that has gained traction is sometimes called a unified ledger: a shared platform where central bank money, tokenized commercial bank deposits and tokenized assets can interact. The Bank for International Settlements has promoted this idea as a way to combine the benefits of tokenization with the singleness and safety of central bank money.

The main projects

Switzerland has gone furthest. After a series of experiments, the Swiss National Bank began a pilot in which wholesale central bank money was issued on a regulated digital exchange, allowing real transactions in tokenized bonds to settle in central bank money. The Eurosystem ran exploratory trials in 2024 and has since outlined a two-track approach: a nearer-term solution to connect market DLT platforms with its existing settlement system, and a longer-term vision for an integrated, possibly unified, ledger architecture.

The future of central bank money may be decided less in consumer apps than in the settlement layer nobody sees.

Tokenized deposits and the role of banks

Wholesale CBDC is only half the picture. Large banks have built platforms for tokenized deposits, digital representations of ordinary bank deposits that can move on programmable ledgers between clients and institutions. These are, in effect, the private money counterpart to wholesale CBDC. Central banks generally prefer this model over stablecoins issued by non-banks, because tokenized deposits remain inside the regulated banking system, covered by capital requirements and deposit insurance.

The arrival of the GENIUS Act in the United States last July has added pressure. With a federal framework for dollar stablecoins now in place, and those stablecoins increasingly used to settle tokenized assets on public blockchains, banks and central banks elsewhere are asking whether they need a regulated alternative with central bank money at its core. The US itself has not pursued a wholesale CBDC as actively, relying instead on private innovation and existing Federal Reserve systems.

Risks and open questions

• Interoperability: multiple platforms could fragment liquidity unless they connect cleanly.
• Governance: shared ledgers raise questions about who operates them and who is liable when things go wrong.
• Geopolitics: cross-border platforms can become tools for bypassing existing payment networks, which is why Western central banks are cautious about some multilateral projects.
• Legal certainty: the finality of settlement on new ledgers must be clearly recognized in law.

There are also questions about the pace of adoption. Tokenized bond issuance and tokenized money market funds have grown, but they remain small compared with conventional markets. Financial institutions will invest heavily only if there is enough liquidity on new platforms, and liquidity will come only if institutions invest. Central bank participation is meant to break that chicken-and-egg problem by providing a trusted settlement asset.

Commercial banks have mixed feelings. Wholesale central bank money on new ledgers could lower their settlement costs and open new business lines in tokenized assets. It could also make it easier for non-bank firms, such as large asset managers or payment companies, to compete in services banks have traditionally dominated, especially if central banks broaden access to their settlement systems. Several central banks have been cautiously reviewing which institutions should have direct access, a decision that will shape competition in finance as much as any technology choice.

What it means for the bigger CBDC debate

The rise of wholesale projects suggests that the future of central bank money may be less dramatic, and more consequential, than the retail debate implies. On the retail side, Europe continues its slow path toward a possible digital euro, with the ECB having decided last autumn to move to the next phase of preparation while legislation is still pending, and the US has ruled out a digital dollar. On the wholesale side, a broad coalition of central banks is converging on the view that tokenized finance needs central bank money at its core.

The bottom line

Money is not ending, but its plumbing is being rebuilt. If tokenization becomes the standard way to issue and trade financial assets, the question of whether settlement happens in central bank money, tokenized bank deposits or private stablecoins will shape financial stability for decades. That question is being answered now, in pilots and technical papers rather than headlines. This article is analysis and not investment advice.
