A central bank digital currency is digital money issued directly by a country’s central bank. It is a public alternative to private stablecoins, and by 2026, the world had split sharply over whether to build one, with the United States banning its own and Europe and China racing ahead.
SummaryTable of Contents
A central bank digital currency, or CBDC, is the digital form of a country’s official money, issued and backed by its central bank. Where a stablecoin is a private company’s dollar token and a bank deposit is a claim on a commercial bank, a CBDC is a direct claim on the central bank itself, the same institution that issues physical cash. It is, in the simplest terms, government digital money.
The idea has moved from theory to a live global experiment. By 2026, the Atlantic Council counted around one hundred thirty-four to one hundred forty-six countries, representing the overwhelming majority of world economic output, exploring a CBDC in some form, up from a handful a few years earlier. A few are live, several are in pilots, and the largest economies have taken opposing paths.
This guide explains what a CBDC actually is, how it differs from the money you already use, the two main designs, what is running in 2026, and the deep arguments for and against the whole concept.
A CBDC is money issued by a central bank in digital form, held and spent through phones, cards, or accounts instead of as physical notes and coins.
The defining feature is who stands behind it. A central bank is the institution that issues a nation’s currency and serves as the ultimate backstop of its financial system. When a central bank issues a CBDC, holding that digital money is holding a direct claim on the central bank, carrying the same credit safety as physical cash, which never defaults because the issuer can always honor it. That is a different and stronger guarantee than the claims behind the other forms of money people use every day.
A CBDC aims to bring the safety of central bank money into the digital age.
Physical cash is a central bank liability, but it is slow, hard to use online, and shrinking in everyday use. Bank deposits are digital and convenient but are claims on commercial banks, protected only up to insured limits. A CBDC tries to give people digital money with the convenience of a bank app and the safety of cash, issued straight by the central bank. Whether that is desirable is exactly the debate the world is having.
The clearest way to understand a CBDC is to place it beside the other forms of money and ask one question of each: who owes you the value?
With physical cash, the central bank owes you. A banknote is a direct liability of the central bank, which is why it is considered the safest money there is. With a bank deposit, a commercial bank owes you. The dollars in your checking account are a claim on that bank, convenient and digital but dependent on the bank’s health, backed by deposit insurance only up to a limit. With a stablecoin, a private company owes you. The token is a claim on the issuer’s reserves, governed by whatever rules apply to that issuer, and it is only as sound as those reserves and that company. With a CBDC, the central bank owes you again, like cash, but in digital form usable online and through apps.
That single question, who owes you, explains why CBDCs are such a charged idea. A CBDC offers the strongest backing of any digital money, a direct central bank claim. It also means the central bank, an arm of the state, becomes the direct issuer of the money in your pocket, with a potential view into how it moves. The safety and the concern come from the same fact. The state stands behind the money, and the state is closer to it than ever before.
Not all CBDCs aim at the same users, and the split between two designs matters enormously for what a CBDC does and how much it worries people.
A retail CBDC is digital central bank money for the general public, money ordinary people and businesses would hold and spend for everyday purchases. This is the version that sparks the loudest debate, because it puts the central bank directly into daily payments and raises questions about privacy, surveillance, and the role of commercial banks. The live retail CBDCs around the world, in places like the Bahamas, Jamaica, and Nigeria, are this kind, and most have seen modest adoption.
A wholesale CBDC is digital central bank money for financial institutions, used to settle large payments between banks and to move tokenized assets. It never touches ordinary consumers. This version is far less controversial, because it upgrades the plumbing banks already use rather than changing the money in citizens’ hands, and it is where much of the quiet, real progress has happened. Cross-border wholesale projects that link several central banks have settled real transactions and are among the fastest-growing efforts in the field.
The distinction is the key to reading any CBDC headline. A wholesale CBDC is a back-office settlement tool with little effect on daily life. A retail CBDC is a change to the money people use, and that is the one carrying the political weight. Many central banks that cooled on retail CBDCs are still pressing ahead on wholesale ones, because the two raise completely different questions.

Cutting through the talk, only a handful of CBDCs are truly operational, and the gap between exploration and real use is wide.
A small group of retail CBDCs is live and circulating, including the Sand Dollar in the Bahamas, JAM-DEX in Jamaica, and the eNaira in Nigeria, along with a shared system in the Eastern Caribbean. All have struggled to win broad adoption despite being fully launched, a reminder that issuing a CBDC and getting people to use it are different challenges. China’s e-CNY remains the largest program by transaction volume, with cumulative transactions reported around sixteen trillion yuan, roughly two trillion United States dollars, across many cities and hundreds of millions of users, though it is still officially a pilot.
On the cross-border side, wholesale projects that connect several central banks have moved real money between countries, settling trade and currency transactions outside the traditional correspondent-banking system. These efforts have grown quickly and represent some of the most concrete CBDC activity anywhere, even though they stay invisible to ordinary people. The headline figure of well over a hundred countries exploring CBDCs is real, but most of that exploration sits at the research or design stage. The set of CBDCs that actual people or banks use every day remains small, which is the honest state of the field in 2026.
Three programs define the global picture, and their diverging paths tell the larger story.
China’s e-CNY is the most advanced large-economy effort, integrated with major payment apps, accepted across retail chains, and used to pay public wages in some areas. In a notable shift, the People’s Bank of China reclassified the e-CNY as deposit liabilities in early 2026, a change that moves it away from being pure digital cash and toward a digital deposit model, partly to avoid pulling funds out of commercial banks and to open the door to paying interest.
The digital euro is in its decision and preparation stage, with the European Central Bank having finished a multi-year prep phase and moving toward a launch decision, a possible pilot, and a retail rollout that most analysts place around 2027 to 2029. Its design includes a cap on how much each person can hold, reported near three thousand euros, no interest, and a focus on payments rather than savings, all to avoid draining deposits from banks.
The digital pound sits in a design phase in the United Kingdom, drawing its own share of political opposition.
The United States went the other way. Through a combination of an executive order and legislation, including provisions that bar the Federal Reserve from issuing a retail CBDC, the country effectively banned a public digital dollar for years and bet instead on private stablecoins to carry the digital-dollar role. That choice, set against Europe and China building public digital money, created the defining divide of the era: one model where private companies issue the digital dollar under regulation, and another where the central bank issues the money directly.
While retail CBDCs grab the political spotlight, some of the most consequential CBDC work is happening between countries, in wholesale projects designed to move money across borders without the traditional dollar-based system.
The leading example links the central banks of several economies, including China and partners in the Gulf and Southeast Asia, into a shared platform for settling cross-border payments using digital central bank money. These projects have moved real transactions and grown quickly, and their significance is strategic as much as technical. The existing system for moving money between countries runs largely through United States banks and the dollar, which gives Washington visibility and leverage over global payments. A cross-border CBDC network that settles directly between central banks could route around that system, reducing reliance on the dollar and on American financial infrastructure.
This is why CBDCs have become a matter of geopolitics, not just payments. Groups of nations seeking alternatives to dollar dominance have pushed digital-currency links as a way to trade and settle outside Western control. China’s effort to internationalize its digital yuan fits this aim, extending the infrastructure and standards of its currency into other countries. The United States stepping back from a public digital dollar, just as these networks advance, raised concern among some analysts that America could cede the standard-setting role in cross-border digital money to rivals.
The retail CBDC debate is about privacy and the state’s relationship to citizens. The wholesale and cross-border debate is about which countries and currencies control the pipes of global finance in a digital age, and that contest is moving faster and more quietly than the consumer one.
To feel the difference a CBDC makes, follow the same ten-dollar payment through three forms of money.
Pay with a bank card, and the money moves as a claim on your commercial bank. The transaction routes through card networks and banks, settles over a day or more behind the scenes, and your bank and the network can see the payment. The value you spent was a deposit, a claim on your bank, insured up to a limit.
Pay with a stablecoin, and a private dollar token moves from your wallet to the merchant’s in seconds on a blockchain for a tiny fee. The value was a claim on the token’s issuer, backed by its reserves, and the transaction is visible on a public ledger, though tied to wallet addresses rather than names by default.
Pay with a retail CBDC, and digital central bank money moves directly from you to the merchant, settling instantly as a transfer of a central bank claim. There is no commercial bank in the middle of the value itself, and the money carries the safety of cash. The open question is visibility. Depending on the design, the central bank or state could potentially see the payment, which is why privacy features and holding caps dominate the design debates.
The same ten dollars, three different answers to who backed it, how fast it settled, and who could watch it move. Those answers are the whole argument over CBDCs in miniature.
CBDCs split serious people, and the disagreement is not really technical. It is about the role of the state in money.
Supporters point to several gains. A CBDC can extend financial access to people without bank accounts, giving them safe digital money straight from the central bank. It can make payments faster and cheaper, especially across borders. It can strengthen a central bank’s ability to deliver policy, letting support reach people directly during a crisis. And it can offer a public option in a payment system increasingly run by private firms, keeping the state present in the money its citizens use. For wholesale versions, the case is even cleaner: faster, safer settlement between banks and for tokenized assets.
Critics raise concerns that are just as serious. A retail CBDC could give the state a detailed view of how citizens spend, a surveillance capability that worries people across the political spectrum, which is why opponents in the United States framed their ban as a privacy protection. Programmable money, where rules could be built into the currency itself, raises the fear that spending could be restricted or funds altered by authorities. There is also the risk to banks, since money held directly at the central bank is money not held in commercial banks, which could drain deposits and shrink the credit banks provide, a fear that drove both Europe’s holding caps and China’s shift toward a deposit model.
The debate comes down to a trade-off between the safety and reach of public digital money and the privacy and banking risks of putting the central bank that close to everyday payments.
There is a further wrinkle that explains why so many advanced economies quietly cooled on retail CBDCs. When private payment apps and regulated stablecoins already give people fast, cheap digital payments, the marginal benefit of a public retail CBDC shrinks, while the privacy and banking risks remain. A digital euro with a low holding cap, no interest, and strict privacy limits has to answer a hard question: why would an ordinary person choose it over the card or app they already use? Several central banks concluded that the clearest case for digital central bank money sits on the wholesale side, where it upgrades interbank settlement, and that the retail case is weaker than the early enthusiasm suggested.
The American decision to ban a public digital dollar while clearing the way for private stablecoins is the sharpest expression of the global split, and the reasoning is worth understanding.
The official rationale centers on privacy and limits on state power. Lawmakers behind the ban described a central bank digital currency as a potential surveillance tool and argued that monetary innovation should stay with private actors instead of the state. By barring a Fed retail CBDC and protecting private stablecoins with cash-like privacy, the United States chose a model where the digital dollar is issued by companies under rules like the stablecoin framework, not by the government. The bet is that a competitive field of regulated private dollar tokens can deliver the benefits of digital money without handing the central bank direct reach into citizens’ wallets.
The choice carries consequences beyond privacy. With dollar stablecoins already holding far more value than any other digital currency and the United States blessing them with federal rules, the American model exports the dollar’s dominance into the on-chain economy through private tokens. Europe and China, watching dollar stablecoins spread, are building public digital money partly as a response, to keep their own currencies relevant in a digital world tilting toward the dollar.
So the same decision that looks like a privacy stance at home reads abroad as a strategic move, using private stablecoins to extend the dollar while rivals counter with state-issued alternatives. The world ended up with two visions of digital money running at once, and which one proves better is still being decided.
No. A CBDC is issued directly by a central bank and is a claim on that central bank, like cash. A stablecoin is issued by a private company and is a claim on that company’s reserves. A CBDC carries government backing, while a stablecoin carries issuer and reserve risk. The United States chose private stablecoins over a public CBDC.
No, and it has moved to prevent one for years. Through an executive order and legislation barring the Federal Reserve from issuing a retail central bank digital currency, the United States effectively banned a public digital dollar and chose to rely on regulated private stablecoins instead.
A small group of retail CBDCs is operational, including the Sand Dollar in the Bahamas, JAM-DEX in Jamaica, and the eNaira in Nigeria. China’s e-CNY is the largest program by volume but is still officially a pilot. Most of the many countries exploring CBDCs remain at the research or design stage.
That is the central concern with retail CBDCs. Depending on the design, a central bank could potentially see transactions, which is why privacy features and holding limits dominate the design debate. Some designs aim for cash-like privacy on small payments. The degree of visibility depends entirely on how a given CBDC is built.
A retail CBDC is digital central bank money for the general public to use in everyday payments. A wholesale CBDC is for financial institutions to settle large payments and move tokenized assets between banks. Retail versions carry the privacy and banking concerns, while wholesale versions are far less controversial.
If people hold money directly at the central bank through a CBDC, they may pull deposits out of commercial banks. Banks rely on deposits to fund lending, so a large shift could shrink credit. This fear drove Europe’s per-person holding caps and influenced China’s move to treat its digital currency more like a bank deposit.
