A consumer taps a smartphone held out by a vendor in a Shenzhen street market to make a payment. In less than a second, the transaction is finished. No card swipes, no cash exchanges, and no delays. In the real world, it appears as though dozens of people are interacting at the same time across this specific block on a busy afternoon. What differs is what takes place in the database: China’s e-CNY digital currency infrastructure records, timestampes, and links the transaction to the confirmed identities of both parties.
The seller is aware that she received payment. When, where, how much, and by whom are all known to the state. Depending on who is explaining it, this is either a model of an effective, inclusive modern payment infrastructure or an example of what financial surveillance looks like when it is integrated into the money itself. It is the most obvious preview of where central bank digital currencies are headed.
| Category | Detail |
|---|---|
| Definition | Central Bank Digital Currency (CBDC) — a digital form of a nation’s fiat currency, issued and controlled directly by the central bank; represents a direct claim on the central bank, unlike commercial bank deposits |
| Global Adoption Status | Over 130 countries exploring CBDCs as of late 2025 — representing more than 90% of global GDP; over 15 actively piloting, including China (e-CNY), India (Digital Rupee), and the European Central Bank (Digital Euro) |
| China’s e-CNY | Most advanced major economy CBDC — operational across dozens of cities; over 260 million digital wallets opened by 2024; linked to identity and transaction monitoring systems |
| Key Privacy Risk | Unlike physical cash, CBDC transactions are fully traceable by the issuing central bank — every purchase, transfer, and payment can be logged, analysed, and potentially restricted |
| Programmability Concern | CBDCs can technically be designed with “programmable money” features — expiry dates, spending restrictions, geographic limitations — raising concerns about government control over how citizens use funds |
| Financial Inclusion Argument | Proponents argue CBDCs can bring unbanked populations into the financial system by providing a government-backed digital wallet without requiring a commercial bank account |
| Disintermediation Risk | If citizens hold CBDCs directly at the central bank rather than commercial banks, bank deposit bases shrink — reducing banks’ ability to lend and potentially destabilising the credit system |

Currently, more than 130 nations—representing more than 90% of the world’s GDP—are investigating CBDC in some capacity. Over the past four years, that number has increased significantly due to a combination of legitimate policy interest in enhancing payment systems and competitive concern, especially among Western economies, regarding the strategic ramifications of China implementing a state-controlled digital currency at scale while other major economies watch.
A map of increasing institutional activity may be found on the Atlantic Council’s CBDC tracker, which tracks development status across nations. It’s not really a matter of whether CBDCs will emerge. There are already a few. The question is what design decisions governments make when they construct them, and whether those decisions give priority to the users of the currency or the government observing their use.
In some situations, the justification for CBDCs is really strong. cheaper and quicker international payments. Approximately 1.4 billion adults worldwide do not have access to digital payment methods. decreased reliance on the costly, slow correspondent banking system, which is controlled by a few major financial firms.
A government-backed digital currency could more effectively solve these actual issues, which are poorly addressed by current methods. Regarding the issues they are pointing out, central banks who make this claim are not incorrect. The infrastructure being developed to address them is the source of concern.
From the standpoint of civil liberties, physical cash is very uncommon. It’s anonymous. There isn’t a transaction log. No government database keeps track of who spent what at which drugstore, bookstore, or political donation office. For most people, the anonymity of cash is not really important, but it offers a structural defense against a future government that might find it useful to know. By design, a CBDC completely removes that anonymity.
The issuing central bank logs each transaction. The extent to which that data is saved, examined, shared with other organizations, or utilized to limit transactions in the future is solely dependent on policy decisions that governments have not yet made and, frequently, have not been open about.
Privacy activists are especially critical of the programmability question. As a government stimulus tool, CBDCs can theoretically be made to expire—money that needs to be spent within a specific term. They may be limited to specific product categories. Under specific legal or regulatory circumstances, they may be disabled for specific individuals.
The majority of central banks creating CBDCs are openly dedicated to preserving “cash-equivalent” privacy, therefore none of these qualities are necessary. If future administrations determine that the capability is too valuable to disregard, it remains to be seen if those promises will last.
Observing this evolve in several jurisdictions at once gives the impression that the globe is in the midst of making a significant decision regarding the relationship between money and the state without having a very clear public discussion about it. Technical systems are being constructed. There is a significant delay in the policy judgments regarding what those systems will and won’t accomplish. The infrastructure might be too embedded to be altered by the time regular users fully understand the ramifications.
