CBDC Explained: How Central Bank Digital Currency Works in 2026

A central bank digital currency, or CBDC, is a digital liability of a central bank denominated in the national unit of account. A retail CBDC is intended for households and businesses; a wholesale CBDC is generally restricted to financial institutions for settlement. A CBDC is not the same as a bank deposit, privately issued stablecoin or decentralized cryptocurrency.

CBDCs do not have to use a blockchain. Central banks can choose centralized databases, distributed ledgers or hybrid infrastructure. The defining feature is the issuer and legal claim, not the database technology.

Global CBDC status in 2026

CBDC research is widespread, but launch is not inevitable. The BIS reported that 85 of 93 central banks surveyed in 2024 were exploring a retail CBDC, wholesale CBDC or both. An IMF review published in 2025 identified three launched retail CBDCs—the Bahamas’ Sand Dollar, Jamaica’s JAM-DEX and Nigeria’s eNaira—while listing China and several other jurisdictions as pilots.

Major economies remain at different stages:

China’s e-CNY continues as a pilot, and the People’s Bank of China describes its expansion as prudent and orderly.
The European Central Bank is preparing a limited beta pilot; it says any possible first issuance would depend on legislation and a later decision.
The Bank of England and HM Treasury are completing a design phase, with no decision yet to introduce a digital pound.
The US Federal Reserve says it has made no decision to pursue or implement a CBDC.

What a CBDC can and cannot change

A retail CBDC could provide public money for digital payments, improve resilience or competition, and support carefully designed offline or inclusive access. Wholesale systems may improve delivery-versus-payment, interbank settlement or cross-border experiments. These are potential design outcomes, not automatic benefits.

A CBDC does not remove exchange-rate risk, sanctions, capital controls, compliance checks or the need for international cooperation. Cross-border transfers remain subject to compatible legal frameworks and technical interoperability. Nor is a CBDC inherently anonymous: privacy depends on system design, data access, intermediaries and law.

Potential risks include cyberattack, operational outages, surveillance or data misuse, exclusion of people without suitable devices, bank-deposit outflows and faster runs during stress. Many proposals therefore use intermediated distribution, holding limits, tiered identity checks or non-interest-bearing balances.

What are Central Bank Digital Currencies (CBDC) – will they mark the start of a revolution to change the financial system forever? CBDCs are digital currencies issued by central banks that function as National Currencies (fiat). They are a direct replacement of paper money, with the exact same value and issuance policies. CBDCs are state-sanctioned and governed by the monetary authority and regulatory law.

Banks around the world are racing to issue out Central Bank Digital Currencies (CBDC). China has already deployed the test trial for Digital Currency Electronic Payment (DCEP), a digital version of the RenMinBi based on cryptographic technology. Japan immediately countered this announcement by plans to release a Digital Yen in “2 to 3” years. One of the key motivations behind CBDC is to drastically improve the way money is transferred around the world. Instead of relying on decade-old technologies like SWIFT, Digital Currencies can be transferred directly without friction. This will drastic impacts on all levels of banking, from the m0 reserve system to the unbanked.

Major newspaper outlets like The Guardian and the Economist began writing opinion pieces, calling the advancement from China a big step and one that could pose a threat to US economic hegemony. On the other side, commentators in China heralded their country’s fast work and implementation. Although the US and its state banks have been slow to announce any research plans and have seemingly stopped Facebook’s Libra (a privatized answer to a CBDC) in its tracks, other western nations have quickly begun research.

Global effort to deploy Central Bank Digital Currencies

Earlier this year, banks from the UK, EU, Japan Canada, Switzerland, and Sweden all began joint research on a CBDC. France has announced intentions to test a pilot CBDC in 2020.

In Asia, the Japanese immediately announced their intentions to create a CBDC to match China’s as soon as the news began to break. The Bank of Korea is also looking at its own digital currency. Smaller national banks like Thailand, the Philippines, and Singapore are also looking into creating their own. Projects such as Singapore’s Ubin work with the Monetary Authority of Singapore are already in Phase 5 of development.

The world is moving towards CBDC and is in agreement that this will be the currency of the future. But, what makes them so special and alluring to banks and governments?

Digital Currencies as a weapon to combat economic change

The main reason is its cost-effectiveness and control. CBDCs are not subject to long processing times and costly fees. As you can see from the stable coin market, sending and receiving cryptocurrencies can be done quickly and easily, with just a phone and internet connection required. Not only that, but digital currencies are far easier to track making money laundering tracking much easier.

Another factor is CBDC’s resilience to political or economic changes. Often citizens from emerging economies are subject to a large disparity in their currency’s health in the market when compared to exchange rates, however, stable coins rarely have major shifts. Not only that, but big banking shutdowns, like seen in Greece and Iceland might well have had a solution if they held a financial alternative to store their money. This benefit of digital currencies could well be important as the world stares recession in the face following the economic stresses of the Coronavirus effort.

However, there is one major detail that is propelling some nations’ research. The threat which CBDC’s pose to the US dollar domination. ChinaDaily called the People’s Bank of China’s DCEP a “functional alternative to the dollar settlement system.” This is something politicians in Beijing want as US sanctions are made effective namely due to the dollar being the reserve currency. This means often international transfers to sanctioned states are prohibited and banks shut down, as they are using the US dollar in the exchange.

Challenging US sanctions

The theoretical ability of CBDC’s to circumvent US dominance is something numerous embattled nations have looked to pounce on. Other countries who hold national digital currencies include Iran- a country ravaged by US sanctions and Venezuala- a similarly hit nation. Other US adversaries that have begun research into their own CBDC include Cuba, North Korea, and Palestine.

Clearly, the race is on between the various competing nations to launch their own digital currencies and make a new economic framework. Who will lead the charge remains to be seen, but the answer could have major consequences for the future.

Frequently asked questions

What is a central bank digital currency?

A CBDC is a digital liability of a central bank denominated in the country's official unit of account.

Is a CBDC a cryptocurrency?

Not in the usual decentralized sense. A CBDC is issued and governed by a central bank, while cryptocurrencies generally rely on separate protocol rules and market-based value.

Does a CBDC require blockchain?

No. A central bank can use a centralized ledger, distributed ledger or hybrid design. Issuance by the central bank is the defining feature.

What is the difference between retail and wholesale CBDCs?

Retail CBDCs are designed for public payments. Wholesale CBDCs are generally limited to banks and other eligible institutions for settlement.

Which countries have launched a retail CBDC?

An IMF review published in 2025 identified the Bahamas, Jamaica and Nigeria as having launched retail CBDCs. Other prominent projects remained pilots or research programs.

Is China's e-CNY fully launched?

The People's Bank of China continues to describe e-CNY as a pilot program, although its regions and use cases have expanded.

Has the United States approved a digital dollar?

No. The Federal Reserve says it has made no decision to pursue or implement a CBDC.

Would a CBDC replace cash?

That depends on national policy. Major proposals such as the digital euro describe CBDC as a complement to banknotes and coins, not an automatic replacement.

Are CBDC payments anonymous?

Not necessarily. Privacy and identity rules vary by design, and compliance obligations can require intermediaries or authorities to access some data.

Can a CBDC make cross-border payments instant?

Only if participating systems, laws and institutions are interoperable. A digital format alone does not remove foreign-exchange, sanctions or compliance processes.
