What Is a CBDC? Central Bank Digital Currencies Explained (2026)

A CBDC is digital cash issued directly by a central bank. Learn how CBDCs work, which countries have launched them, and what risks they carry in 2026.

A central bank digital currency, or CBDC, is a digital form of a country's official currency issued and backed directly by the nation's central bank. Unlike the balance you see in your bank app, a CBDC is not a claim on a private institution. It is a liability of the central bank itself, carrying the same legal status as a physical banknote but existing only in digital form. As of May 2026, 146 countries and currency unions representing over 98% of global GDP are at some stage of exploring a CBDC, with five retail CBDCs already live and roughly 41 pilots underway.

How a CBDC differs from the money in your bank account

Most people think of their bank balance as money. Technically, it is not. The digits on your banking app represent a promise from a private institution, a commercial bank, to pay you that amount. If the bank fails, that promise is at risk. Deposit insurance schemes like the FDIC cover up to a threshold, but the underlying claim is on a private entity.

A CBDC changes that structure. When you hold a CBDC, you hold a direct digital claim on the central bank. There is no private intermediary sitting between you and the state. The risk profile is fundamentally different because a sovereign government cannot default on its own currency in the same way a private bank can become insolvent.

This distinction also separates a CBDC from existing digital central bank money. Central banks already issue digital money today, but that access is restricted to commercial banks. Ordinary people cannot hold accounts at the Federal Reserve or the European Central Bank. A retail CBDC would change that, giving individuals and businesses direct digital access to sovereign money for the first time.

How CBDCs work

The mechanics of a CBDC vary depending on who it is designed for.

Retail CBDCs

A retail CBDC is designed for the general public. Citizens hold balances in a digital wallet on their phone or a card, and those balances represent central bank money. Transactions settle directly on the central bank's ledger or through a supervised payment layer managed by licensed intermediaries.

Most central banks favour a two-tier model for retail CBDCs. In this model, the central bank issues the currency and maintains the core ledger, but private banks and payment providers handle customer onboarding, wallets, and customer service. This keeps the central bank out of the retail banking business while preserving the sovereign backing of the money.

Wholesale CBDCs

A wholesale CBDC is not for the public. It is a digital form of central bank reserves used exclusively by commercial banks and other licensed financial institutions for interbank settlement, securities transactions, and cross-border payments. Wholesale CBDCs and retail CBDCs serve entirely different parts of the financial system: one modernises consumer payments, the other modernises the plumbing of global finance.

The technology: permissioned ledgers and DLT

CBDCs do not all use the same technology. Some use distributed ledger technology similar to blockchain, while others run on upgraded centralised databases. The key distinction from public blockchains like Bitcoin or Ethereum is permission: a CBDC ledger is a permissioned system where only approved participants can validate transactions. The central bank retains ultimate authority over the ledger, issuance, and any modifications to the system.

Five reasons governments are building CBDCs

Central banks do not pursue CBDCs out of a fascination with technology. Each project has specific policy goals behind it.

1. Reducing dependence on private payment rails. Most consumer payments today flow through Visa, Mastercard, or a handful of private networks. Central banks see this as a systemic risk. A CBDC gives governments a payment infrastructure they control directly.

2. Improving cross-border settlement. Sending money internationally today involves correspondent banks, multiple intermediaries, and fees that can reach 6-7% of the transfer amount. Wholesale CBDC projects like Project mBridge have demonstrated near-instant, low-cost settlement across borders, with $55.5 billion processed on that platform through early 2026.

3. Preserving monetary sovereignty. In countries where the US dollar has displaced the local currency for everyday transactions, a CBDC gives the central bank a tool to reassert domestic monetary control. This is a significant driver for CBDCs in parts of sub-Saharan Africa, Southeast Asia, and Latin America.

4. Financial inclusion. An estimated 1.4 billion adults globally remain without a bank account, concentrated in sub-Saharan Africa, South Asia, and parts of Latin America. A CBDC accessible through a basic smartphone could extend payment services and government benefits to populations that private banks do not serve profitably.

5. New monetary policy tools. A CBDC opens the possibility of applying targeted interest rates or programmable incentives directly at the currency level, capabilities that are difficult or impossible with physical cash. This remains theoretically appealing to economists and practically controversial among civil liberties advocates.

CBDC vs Cryptocurrency vs Stablecoin

These three types of digital money are often confused. They are structurally different in important ways.

Feature	CBDC	Cryptocurrency (e.g. Bitcoin)	Stablecoin (e.g. USDC)
Issuer	Central bank (government)	No issuer; decentralised protocol	Private company
Backing	Full faith and credit of the state	Market demand; no backing	Fiat reserves or collateral
Price stability	Pegged 1:1 to national currency	Highly volatile	Designed to hold a peg
Legal tender	Yes	No (in most jurisdictions)	No
Privacy	Permissioned; identity required	Pseudonymous	Varies; mostly permissioned
Control	Centralised; government authority	Decentralised	Centralised (issuer)
Programmability	Possible by design	Limited; smart contracts on some chains	Yes, via smart contracts
Counterparty risk	Sovereign (minimal)	Protocol risk	Issuer solvency risk
Regulatory status	Fully regulated	Varies by jurisdiction	Evolving (MiCA, GENIUS Act)

The most important distinction is control. A cryptocurrency like Bitcoin operates on a network where no single party has authority. A stablecoin like USDC is issued by Circle, a private company, whose solvency and regulatory compliance determine whether the peg holds. A CBDC is issued by the state. It carries the backing of the sovereign but also the surveillance and control capabilities that come with it.

Where CBDCs stand in 2026

The global CBDC landscape in 2026 is a patchwork of live deployments, ambitious pilots, and notable retreats.

The five live retail CBDCs

The Bahamas: Sand Dollar. Launched in October 2020, the Sand Dollar was the world's first retail CBDC. Issued by the Central Bank of the Bahamas, it was designed to improve payment access across a scattered archipelago where physical banking infrastructure is limited.

Nigeria: eNaira. Nigeria launched the eNaira in October 2021, making it the first CBDC in Africa and one of the most closely watched experiments in the world. Adoption has been slow. Active wallets remain in the low millions against a population of 220 million, a gap that reflects the challenges of driving behaviour change in an economy where mobile money and cash are deeply embedded.

Eastern Caribbean: DCash. The Eastern Caribbean Currency Union launched DCash in 2021, covering eight island nations. The project experienced a technical outage in 2022 and relaunched in a second phase. It remains the only multi-country retail CBDC in operation.

Jamaica: JAM-DEX. Jamaica's CBDC launched in mid-2022 and operates through a government-mandated wallet called Lynk. Jamaica offered financial incentives to drive early adoption, a model other nations have watched closely.

China: e-CNY (digital yuan). China's digital yuan is the largest CBDC project in the world by any measure. By November 2025, the e-CNY had processed over 3.4 billion transactions worth approximately 16.7 trillion renminbi, roughly $2.3 trillion, across more than 30 cities and 225 million personal wallets. The e-CNY remains technically classified as a pilot, but the boundary with full production has blurred significantly. In January 2026, a new management framework took effect granting the e-CNY legal deposit status and introducing a 0.05% interest rate, making it the world's first interest-bearing CBDC.

Advanced pilots to watch

The Digital Euro is in its preparation phase, which the European Central Bank expects to run through 2026. A retail launch is not anticipated before 2027 or 2028. The Digital Euro is explicitly being designed without spending programmability, following public consultation feedback on privacy concerns.

The UK Digital Pound, sometimes called Britcoin, is in its design phase. The Bank of England has confirmed the digital pound will not carry programmable spending restrictions, addressing public concerns about government control of consumer purchases.

India's digital rupee (e-Rupee) has been in retail and wholesale pilot phases since late 2022. India is one of the largest economies with an active CBDC pilot and is seen as a bellwether for CBDC adoption in developing markets.

The United States: banned and stepping back

The United States is notable as the only G20 nation not actively pursuing a retail CBDC. In January 2025, President Trump signed Executive Order 14178, which prohibited US agencies from promoting or developing a central bank digital currency. Federal Reserve Chair Jerome Powell stated he would not issue a CBDC while leading the institution. The House of Representatives passed the Anti-CBDC Surveillance State Act, blocking Federal Reserve CBDC issuance without explicit Congressional authorisation. In March 2026, the US Senate carried a CBDC ban through 2030 as an amendment to a housing bill.

The US approach is instead to support regulated private stablecoins through the GENIUS Act, signed in 2025, which established a licensing and reserve framework for dollar-pegged stablecoins.

Cross-border: wholesale CBDCs at scale

The most significant progress in wholesale CBDCs has come through two major multilateral projects.

Project mBridge is a multi-CBDC cross-border settlement platform built in collaboration by the Bank for International Settlements, the People's Bank of China, the Hong Kong Monetary Authority, the Bank of Thailand, the Central Bank of the UAE, and the Saudi Central Bank. By early 2026, mBridge had settled over $55.5 billion in cross-border transactions, a nearly 2,500-fold increase from its early 2022 pilots. The BIS formally exited the project in October 2024, framing the move as a graduation to reflect the project's maturity.

Project Agora is the BIS-led successor effort, involving seven central banks: the Federal Reserve Bank of New York, the Bank of England, the Banque de France (representing the Eurosystem), the Bank of Japan, the Bank of Korea, the Bank of Mexico, and the Swiss National Bank. Agora focuses on tokenised deposits and wholesale cross-border settlement within a framework more aligned with western regulatory standards.

Programmable money: what a CBDC can be designed to do

One of the most debated features of CBDCs is programmability. Unlike physical cash, a CBDC is software. That means the issuer can, in theory, embed rules directly into the currency.

The range of capabilities that have been discussed or piloted includes:

Expiry dates. In a Shenzhen e-CNY trial, digital yuan was programmed with an expiration date to encourage spending and discourage hoarding. The money ceased to be valid after a set period.
Merchant restrictions. A CBDC could be limited to purchases at specific types of merchants, for example, government-issued welfare funds that can only be spent on food or healthcare.
Geographic limits. Currency could be programmed to work only within a specific region.
Programmable interest rates. The central bank could apply a negative interest rate to holdings above a certain threshold to discourage excessive saving during an economic downturn.
Conditional transfers. Government payments could be structured so that funds are released only when a specific condition is met, such as completion of a training programme.

Proponents argue these capabilities make CBDCs powerful tools for targeted social policy. Critics point to the same features as instruments of financial surveillance and control.

Not all CBDC projects pursue programmability. The Bank of England explicitly confirmed the UK digital pound will not include programmable spending restrictions. In July 2023, Brazil published the source code for its CBDC pilot, revealing mechanisms that would allow the central bank to freeze or reduce funds in user wallets, a disclosure that reignited privacy debates globally.

CBDC risks and concerns

CBDCs carry genuine risks alongside their potential benefits. Understanding both is essential for anyone tracking how digital money is evolving.

Privacy and surveillance. A CBDC gives the issuing authority a complete, real-time record of every transaction. Where cash provides anonymity, a CBDC creates a financial audit trail tied to verified identity. The degree of privacy protection depends entirely on how the system is designed and governed, and those design choices are made by governments. The US House of Representatives cited privacy concerns explicitly in passing the Anti-CBDC Surveillance State Act.

Banking sector disintermediation. If households hold CBDC wallets directly with the central bank, they may shift deposits away from commercial banks. Reduced deposit bases would constrain commercial banks' ability to lend, potentially tightening credit for businesses and households. This is one reason most CBDC designs use a two-tier model that keeps commercial banks in the distribution chain.

Cybersecurity vulnerabilities. A CBDC concentrates enormous value in a single digital infrastructure. A successful attack on the central bank's ledger could have systemic consequences. The technical security requirements for a national CBDC are orders of magnitude beyond those for a private payment app.

Adoption challenges. Adoption has proven harder than expected. Nigeria's eNaira is the clearest example: launched in October 2021 with considerable fanfare, it has achieved wallet counts in the low millions in a country of 220 million people. The barriers include limited smartphone penetration, distrust of government financial systems, and the friction of changing established payment habits.

Geopolitical fragmentation. The divergence between Project mBridge (China-led) and Project Agora (Western central bank-led) is already creating parallel rails for cross-border CBDC settlement. If CBDC infrastructure splits along geopolitical lines, it could deepen fragmentation in global finance rather than improve interoperability.

CBDCs and financial inclusion

Financial inclusion is one of the strongest arguments for CBDCs, particularly in developing economies. An estimated 1.4 billion adults globally remain without a bank account, concentrated in sub-Saharan Africa, South Asia, and parts of Latin America. In many of these regions, mobile phone penetration already exceeds bank account penetration, which means a smartphone-based CBDC could reach people that traditional banking infrastructure never will.

The potential benefits are specific. A CBDC can enable direct government-to-person payments for social transfers and disaster relief without routing funds through a bank account or a private remittance operator. It can build a financial history for people who previously had no credit footprint. And it can lower the cost of small transactions to near zero, making micropayments viable in ways that bank fees currently prevent.

The limits are real too. A 2023 IMF working paper found that while CBDCs can contribute to financial inclusion, they cannot resolve the root causes of financial exclusion: low incomes, distrust of institutions, lack of digital literacy, and absence of identification documents. A CBDC is a financial tool, not a development programme. Achieving meaningful inclusion requires addressing those underlying barriers alongside the technology.

Frequently asked questions

Is a CBDC a cryptocurrency?

No. A CBDC is issued by a central bank, is centralised by design, and maintains a stable value equal to the national currency. Cryptocurrencies like Bitcoin are decentralised, not backed by any government, and have volatile market prices.

Is a CBDC the same as a stablecoin?

No. A stablecoin is issued by a private company and pegged to a fiat currency through reserves or collateral. A CBDC is issued by the state and is a direct liability of the central bank. They may serve similar payment functions, but the credit risk and governance structures are entirely different.

Which country has the most advanced CBDC?

China's e-CNY is the most advanced retail CBDC by adoption metrics: 225 million personal wallets and approximately $2.3 trillion in transactions processed by November 2025. Among smaller economies, the Bahamas' Sand Dollar and Nigeria's eNaira have been live the longest.

Does the US have a CBDC?

No. The United States banned retail CBDC development through Executive Order 14178 in January 2025. The US is instead supporting regulated private stablecoins through the GENIUS Act. The Federal Reserve continues limited wholesale CBDC research through the New York Fed's innovation centre.

Can the government freeze my CBDC wallet?

It depends on how the CBDC is designed. Brazil's CBDC pilot code, made public in July 2023, included mechanisms to freeze or reduce wallet balances. The degree of government control varies by jurisdiction and depends on the legislative framework governing the CBDC.

Is a CBDC legal tender?

Yes, in jurisdictions where a CBDC has been formally issued. A CBDC carries the same legal tender status as physical banknotes.

What is the difference between a CBDC and digital banking?

The money in your bank account is a liability of a private commercial bank. A CBDC is a liability of the central bank. If your commercial bank fails, your bank balance is at risk up to deposit insurance limits. A CBDC carries the credit of the sovereign.

Will CBDCs replace cash?

Most central banks have explicitly stated they do not plan to replace physical cash with CBDCs. The goal is to offer a digital alternative alongside cash, not to eliminate it.

Is China's digital yuan a CBDC?

Yes. China's e-CNY, also called the digital yuan, is a central bank digital currency issued by the People's Bank of China. It has been in pilot since 2019 and as of January 2026 operates under a new framework that gives it legal deposit status and a 0.05% interest rate.

What is an interest-bearing CBDC?

An interest-bearing CBDC pays holders a rate of return on their balance, similar to a savings account but at the central bank level. China's e-CNY became the world's first CBDC to pay interest when its new framework took effect on January 1, 2026, at a rate of 0.05%.

The bottom line

A CBDC is digital cash issued by a central bank, carrying the legal standing of physical currency in a digital format. The concept is straightforward. The execution is politically and technically complex, and the policy choices built into each system shape whether a CBDC serves the public or creates new instruments for financial control.

In 2026, the global picture is fragmenting. Five retail CBDCs are live, with mixed adoption results. The largest economies are split: China is deepening its digital yuan infrastructure, the European Union is building toward a Digital Euro launch in the late 2020s, and the United States has banned retail CBDC development outright while redirecting the conversation toward regulated private stablecoins.

The programmability and privacy questions will not be settled by technology. They will be settled by legislation, public demand, and the choices governments make about how much transparency their citizens should have into how digital money is designed and who controls it.
