What Is a CBDC? Central Bank Digital Currency (2026)

What Is a CBDC? Central Bank Digital Currency Explained

Author: Meesam Abbas | Last Updated: July 2026 | Sources: Federal Reserve, Atlantic Council, ECB, White House, BIS, Forbes

A central bank digital currency — CBDC — is "a digital liability of a central bank that is widely available to the general public," according to the Federal Reserve's own definition. (Federal Reserve, February 2026) While the United States banned the creation of a CBDC by executive order on January 23, 2025, 146 countries representing over 98% of global GDP are now actively exploring one — and China's digital yuan has already processed more than 3.4 billion transactions worth approximately $2.3 trillion. (Atlantic Council, May 2026) CBDC development is one of the most consequential financial infrastructure races of the 21st century — and whether or not the US participates, the outcome will reshape global payments, dollar dominance, and your financial privacy.

Key Takeaways

  • A CBDC is a digital form of a country's currency issued directly by the central bank — not a bank deposit, not a stablecoin, and not a cryptocurrency like Bitcoin. The Federal Reserve defines it as "a digital liability of a central bank that is widely available to the general public." (Federal Reserve, February 2026)
  • 146 countries representing over 98% of global GDP are now exploring a CBDC — up from just 87 in May 2022. Every G20 nation except the United States is actively pursuing one, with 14 G20 members already in the pilot phase. (Atlantic Council, May 2026)
  • China's digital yuan (e-CNY) has processed more than 3.4 billion transactions worth approximately 16.7 trillion renminbi — roughly $2.3 trillion — as of December 2025, making it by far the world's largest CBDC pilot. (Atlantic Council, May 2026)
  • President Trump signed an executive order on January 23, 2025 explicitly prohibiting US federal agencies from establishing, issuing, or promoting a CBDC — describing digital currencies as threatening "the stability of the financial system, individual privacy, and the sovereignty of the United States." (White House, January 2025)
  • The mBridge cross-border CBDC platform — involving China, Hong Kong, Thailand, the UAE, and Saudi Arabia — processed $55.49 billion in transactions by 2026, a 2,500-fold increase since its 2022 pilots, with the digital yuan accounting for over 95% of settlement volume.

What Is a CBDC? Central Bank Digital Currency (2026)

What Is a CBDC?

Quick Answer: A CBDC — central bank digital currency — is digital money issued directly by a country's central bank. Unlike a bank deposit, which is a liability of a commercial bank, a CBDC is a direct liability of the central bank itself — the same institution that issues physical banknotes. The Federal Reserve defines it as "a digital liability of a central bank that is widely available to the general public."

To understand what a central bank digital currency actually is, it helps to understand what it is not. It is not a cryptocurrency like [Bitcoin] — it has no fixed supply, no decentralisation, and no anonymity by design. It is not a stablecoin like USDC — those are issued by private companies and backed by reserves, not by the sovereign authority of a central bank. It is not a bank deposit — when you hold money in a commercial bank, you are an unsecured creditor of that bank. If the bank fails, your money is at risk up to deposit insurance limits. With a CBDC, you hold a direct claim on the central bank itself — which, as the ultimate issuer of the currency, carries no credit risk.

The Atlantic Council defines it simply: "A CBDC is virtual money backed and issued by a central bank." (Atlantic Council, May 2026) The Federal Reserve adds a critical qualifier in its definition — "widely available to the general public" — which distinguishes a retail CBDC (for everyday citizens and businesses) from a wholesale CBDC (for use between financial institutions in interbank settlement). Both types are being developed globally, but they serve fundamentally different purposes. A retail CBDC would be the digital equivalent of cash in your pocket. A wholesale CBDC would be the digital equivalent of the reserves banks hold at the central bank.

The potential benefits that have driven 146 countries to explore CBDCs are real and significant. Financial inclusion — reaching the unbanked populations that have no access to commercial banks. Payment efficiency — instant settlement that eliminates the 2–3 day clearing delays built into today's banking infrastructure. Reduced transaction costs — eliminating the multiple intermediaries that each take a cut of every payment. Improved monetary policy transmission — the ability to distribute stimulus payments instantly to every citizen's digital wallet, as happened imprecisely and slowly with physical stimulus checks during COVID-19. (Atlantic Council, May 2026) For the stablecoin comparison in depth, see [What Is a Stablecoin? USDC, USDT, and the GENIUS Act Explained].

The Global CBDC Race: 146 Countries and Counting

Quick Answer: The global CBDC race has accelerated dramatically since 2022. As of May 2026, 146 countries representing over 98% of global GDP are exploring a CBDC — up from 87 in May 2022. Three countries have fully launched one: the Bahamas (Sand Dollar), Jamaica (JAM-DEX), and Nigeria (eNaira). All three have faced slow adoption but continue expanding their domestic coverage.

The numbers from the Atlantic Council's CBDC Tracker — the most comprehensive global database on the subject — reveal how quickly this landscape has shifted. (Atlantic Council, May 2026) In May 2022, 87 countries were exploring a CBDC. By May 2026, that number had grown to 146 — nearly every nation on earth. Of those, 77 are in the advanced phase of exploration, meaning they are actively developing, piloting, or have already launched. There are currently 41 active CBDC pilots running simultaneously around the world.

The three fully launched CBDCs — the Bahamas' Sand Dollar, Jamaica's JAM-DEX, and Nigeria's eNaira — share a common characteristic: they targeted populations with limited access to traditional banking infrastructure. All three have faced the central challenge of every CBDC deployment: consumer adoption. People who already have bank accounts and credit cards have limited incentive to shift to an unfamiliar digital currency, particularly when the existing payment systems work adequately. The most honest assessment of these launches is that they have proven the technology is viable while revealing that technology alone is insufficient — adoption requires incentives, merchant acceptance, and infrastructure that small economies struggle to build simultaneously.

The more geopolitically significant developments are happening at the advanced economy level. The European Central Bank is targeting a digital euro launch by 2029. China's e-CNY pilot has reached extraordinary scale. And the mBridge wholesale platform is already functioning as a cross-border settlement rail operating entirely outside the dollar-correspondent banking system. These are not experiments in financial inclusion — they are experiments in financial architecture that will determine how the global monetary system is structured in the decades ahead. For the de-dollarization context surrounding these developments, see [What Is De-Dollarization? Why the Dollar's Reserve Status Is Declining].

China's Digital Yuan: The World's Largest CBDC Pilot

Quick Answer: China's e-CNY — the digital yuan — is the world's largest CBDC pilot by every measurable metric. By December 2025, it had processed more than 3.4 billion transactions worth approximately 16.7 trillion renminbi — roughly $2.3 trillion. In January 2026, the People's Bank of China reclassified e-CNY as deposit liabilities, a structural change that signals the digital yuan is moving from pilot to permanent infrastructure.

China began developing the digital yuan in 2014 — years before most other central banks had even begun studying the concept. By 2020, the People's Bank of China was running trials in multiple cities. By December 2025, the e-CNY had processed more than 3.4 billion transactions worth approximately 16.7 trillion renminbi — the equivalent of roughly $2.3 trillion. (Atlantic Council, May 2026) This is not a small pilot. For comparison, PayPal processed approximately $1.5 trillion in total payment volume in all of 2023.

The January 2026 reclassification of e-CNY as deposit liabilities by the People's Bank of China is the most significant recent development in the global CBDC story. This accounting change — from a separate category to deposit liabilities — integrates the digital yuan into the existing banking system architecture rather than maintaining it as a parallel instrument. The Atlantic Council noted the reclassification "could signal a shift from its original function as digital cash" while acknowledging "uncertainty about China's plans for e-CNY following the shift." (Atlantic Council, May 2026)

For geopolitical purposes, the domestic scale of the e-CNY matters less than its international ambitions. The mBridge platform — described in detail below — uses e-CNY as its primary settlement currency in cross-border transactions between China and Gulf Cooperation Council countries. The e-CNY makes up over 95% of total settlement volume on mBridge. This means that every barrel of oil, every container of goods, every infrastructure payment settled through mBridge between China and the Gulf runs on China's state-issued digital currency rather than the US dollar. That is a direct structural challenge to the petrodollar system that has anchored dollar dominance since 1974. See [The Petrodollar System Explained: Why Oil Was Priced in Dollars for 50 Years].

The Digital Euro: Europe's 2029 Target

Quick Answer: The European Central Bank is targeting a potential digital euro launch in 2029 — but only if EU co-legislators adopt the necessary regulation in 2026. The ECB's Governing Council moved to the next phase of the project in October 2025. A 12-month pilot is planned to begin in the second half of 2027. ECB President Christine Lagarde has described the digital euro as essential for Europe's "monetary sovereignty and economic security."

The digital euro project is the most transparent and institutionally documented major CBDC initiative in the world. The ECB publishes detailed progress reports, technical analyses, and public FAQs that allow anyone to follow exactly how the project is developing. On October 29, 2025, the ECB's Governing Council confirmed it would move to the next phase — advancing technical readiness, deepening market engagement, and continuing to support the legislative process. (ECB, October 2025)

The ECB's own analysis has addressed the two most common concerns about CBDCs directly. On financial stability — whether a digital euro could trigger bank runs by pulling deposits out of commercial banks — the ECB found that even under "a highly unlikely and extremely conservative crisis scenario worse than any real crisis during the first 25 years of the euro," the digital euro would not harm financial stability, particularly with holding limits up to €3,000 per person. (ECB FAQs, 2026) On cost to the banking sector — the ECB estimated implementation costs would range from €4 billion to €5.8 billion across the European banking system, broadly consistent with previous large infrastructure implementations like the Payment Services Directive. (ECB, October 2025)

The ECB has been careful to frame the digital euro as a complement to cash rather than a replacement for it. ECB President Christine Lagarde stated: "We are working to make its most tangible form — euro cash — fit for the future, redesigning and modernising our banknotes and preparing for the issuance of digital cash." (ECB, October 2025) For the ECB, the strategic motivation is explicit — 13 of 20 eurozone countries currently rely on non-European (primarily American) card payment schemes for the majority of their digital transactions. A digital euro would create a pan-European payment infrastructure independent of Visa, Mastercard, and the US financial system.

The US Has Banned a CBDC — But Is Betting on Stablecoins Instead

Quick Answer: The United States formally banned a CBDC on January 23, 2025, when President Trump signed an executive order prohibiting federal agencies from establishing, issuing, or promoting any central bank digital currency. Instead, the US is betting on privately issued dollar-backed stablecoins — regulated under the GENIUS Act signed July 18, 2025 — as its digital dollar strategy.

The Trump administration's position on CBDCs is the most decisive of any major economy. The January 23, 2025 executive order "Strengthening American Leadership in Digital Financial Technology" contained explicit and sweeping language: "agencies are hereby prohibited from undertaking any action to establish, issue, or promote CBDCs within the jurisdiction of the United States or abroad." (White House, January 2025) Any ongoing plans at any federal agency related to CBDC creation were "immediately terminated."

The stated rationale was explicit. The order described CBDCs as threatening "the stability of the financial system, individual privacy, and the sovereignty of the United States." This is the privacy argument that has driven significant political opposition to CBDCs across the political spectrum: a government-issued digital currency would give authorities the technical ability to monitor every transaction, freeze accounts, restrict spending on specific goods, or program money to expire — capabilities that do not exist with physical cash. The White House Working Group subsequently recommended Congress pass an "Anti-CBDC Surveillance State Act" to codify the executive order ban permanently in legislation. (White House, July 2025)

The US strategy is not to opt out of digital currency — it is to win at digital currency through private-sector dollar-backed stablecoins rather than a government-issued CBDC. The GENIUS Act, signed by Trump on July 18, 2025, created the first federal regulatory framework for stablecoins in US history. (White House, July 2025) The theory: if USDC and USDT — dollar-backed stablecoins — become the dominant form of digital payment globally, the dollar maintains its reserve currency role in a digital age without the government surveillance implications of a CBDC. Whether this strategy succeeds against state-backed digital currencies with the institutional weight of the ECB and People's Bank of China behind them is the central unanswered question in global digital finance.

mBridge: The CBDC Platform Already Running Outside the Dollar System

Quick Answer: mBridge is a multi-CBDC cross-border payment platform involving the central banks of China, Hong Kong, Thailand, the UAE, and Saudi Arabia. It reached minimum viable product in mid-2024, processes transactions in seconds rather than days, and by 2026 had accumulated $55.49 billion in volume — 2,500 times its early 2022 level. By late 2025, mBridge had become a functioning renminbi settlement rail for China-Gulf trade running outside the US-dollar correspondent banking system.

mBridge began as a joint project between the BIS Innovation Hub and the central banks of China, Hong Kong, Thailand, and the UAE in 2021. Saudi Arabia's central bank joined as a full participant in June 2024. The BIS stepped back from the project in October 2024 once it had reached minimum viable product stage — a decision timed, according to Forbes reporting, at least partly because Vladimir Putin had publicly proposed a "BRICS Bridge" based on mBridge's architecture as a mechanism to bypass dollar sanctions. (Forbes, May 2026)

By late 2025, mBridge had become something more significant than a pilot. Forbes described it as "in practice a renminbi-denominated wholesale settlement rail for trade between China and the Gulf, running outside the dollar correspondent system." (Forbes, May 2026) The e-CNY accounts for over 95% of total settlement volume. Transaction volume reached $55.49 billion — a 2,500-fold increase from the early 2022 pilots. (Atlantic Council, May 2026) Cross-border payments that previously took multiple days through the dollar correspondent network now settle in seconds.

The Western response is Project Agorá — launched by the BIS with seven G7-aligned central banks including the Federal Reserve Bank of New York, plus over 40 private institutions including JPMorgan, Citi, HSBC, and SWIFT. Agorá uses a tokenized correspondent banking design that preserves the dollar's role as the routing currency and keeps SWIFT in the messaging layer. The Atlantic Council notes there are now 13 cross-border wholesale CBDC projects globally. The choice between the mBridge architecture — which routes around the dollar system — and the Agorá architecture — which reinforces it — is the defining infrastructure decision in global finance for the next decade.

CBDC Risks: What Could Go Wrong

Quick Answer: CBDCs carry four primary risks identified by the Atlantic Council and global regulators: bank disintermediation — the risk that citizens pull money from commercial banks into CBDCs, triggering a bank run; cybersecurity — central bank systems become high-value attack targets; privacy — governments gain surveillance capability over every transaction; and programmable money — the technical ability to restrict how digital currency is spent or make it expire.

The bank disintermediation risk is the most structurally significant. If citizens can hold money directly at the central bank through a CBDC, they may withdraw funds from commercial banks — particularly during periods of stress when bank safety is in question. Commercial banks use deposits to fund loans. If deposit outflows are large enough, banks must either contract their lending or seek emergency central bank funding. This is why the ECB has focused extensively on holding limits — capping how much digital euro any individual can hold — to prevent large-scale deposit migration from the banking system. (Atlantic Council, May 2026)

The privacy concern is the one that has generated the most political opposition in the United States specifically. A retail CBDC would give the issuing government complete visibility into every transaction made by every citizen. Unlike cash — which is anonymous — or even bank accounts — which require a legal process to access — a government-run CBDC system could be designed to allow real-time monitoring, instant freezing of funds, and programmable restrictions on how money is spent. Critics of CBDCs across both US political parties have cited this as a fundamental threat to financial freedom. The programmable money concern goes further: a CBDC could theoretically be programmed to expire if not spent by a certain date, or to be restricted from purchasing certain categories of goods. Whether these capabilities would ever be used is a governance question — but the technical architecture would make them possible in ways that physical cash never did.

Cybersecurity represents the third major risk category. A central bank digital currency system would become one of the highest-value targets for state-sponsored and criminal hackers in the world — a single system whose compromise could disrupt an entire country's payment infrastructure simultaneously. The distributed nature of commercial banking provides some resilience through redundancy. A centralised CBDC system would require extraordinary cybersecurity architecture to avoid becoming a single point of catastrophic failure.

Frequently Asked Questions

What is a CBDC?

A CBDC — central bank digital currency — is a digital form of a country's official currency issued directly by the central bank. The Federal Reserve defines it as "a digital liability of a central bank that is widely available to the general public." Unlike a bank deposit, a CBDC is a direct claim on the central bank rather than on a commercial bank — meaning it carries no credit risk from bank failure.

What is the difference between a CBDC and Bitcoin?

A CBDC and Bitcoin are fundamentally different. A CBDC is issued and controlled by a government's central bank, has no fixed supply limit, maintains the same value as the national currency, and is centralised. Bitcoin is issued by a decentralised network with no central authority, has a fixed maximum supply of 21 million coins, fluctuates widely in value, and offers anonymity. A CBDC is government money in digital form — Bitcoin is the opposite of that.

Does the US have a CBDC?

No. The United States does not have a CBDC and has formally banned the creation of one by executive order. President Trump signed the order on January 23, 2025, prohibiting federal agencies from establishing, issuing, or promoting any central bank digital currency. The US strategy instead promotes privately issued dollar-backed stablecoins regulated under the GENIUS Act, signed July 18, 2025.

What is China's CBDC?

China's CBDC is called the e-CNY or digital yuan, issued by the People's Bank of China. It is the world's largest CBDC pilot by transaction volume. By December 2025, it had processed more than 3.4 billion transactions worth approximately 16.7 trillion renminbi — roughly $2.3 trillion. In January 2026, China reclassified e-CNY as deposit liabilities, signalling a move from pilot to permanent infrastructure.

What is the difference between a CBDC and a stablecoin?

A CBDC is issued by a government's central bank and is legal tender — it carries the full sovereign backing of the state. A stablecoin like USDC or USDT is issued by a private company and backed by reserves of cash or securities held to maintain a fixed peg to a currency. Both maintain price stability relative to fiat currency, but a CBDC is government money while a stablecoin is a private financial product regulated under commercial law.

When will the digital euro launch?

The European Central Bank is targeting a potential digital euro launch in 2029 — but only if EU co-legislators adopt the necessary regulation in 2026. The ECB moved to its next preparation phase in October 2025 and plans a 12-month pilot beginning in the second half of 2027. The ECB has stated it will only decide whether to issue a digital euro once the legislation has been formally adopted by European lawmakers.

What is mBridge?

mBridge is a multi-CBDC wholesale payment platform involving the central banks of China, Hong Kong, Thailand, the UAE, and Saudi Arabia. It enables cross-border payments in seconds rather than days, settling transactions in central bank digital currencies. By 2026, it had processed $55.49 billion in volume — a 2,500-fold increase from its 2022 pilots — with China's digital yuan accounting for over 95% of settlement volume.

What are the risks of a CBDC?

The four primary CBDC risks are: bank disintermediation — citizens moving money from commercial banks to the central bank, potentially triggering bank runs; cybersecurity — a centralised system becomes a high-value attack target; privacy — governments gain surveillance capability over every transaction; and programmable money — the technical ability to restrict how currency is spent or programme it to expire, raising fundamental concerns about financial freedom.

How many countries have launched a CBDC?

Three countries have fully launched a retail CBDC as of July 2026: the Bahamas (Sand Dollar), Jamaica (JAM-DEX), and Nigeria (eNaira). All three targeted populations with limited access to traditional banking. A further 77 countries are in the advanced phase of development, pilot, or launch, with 41 active pilot projects currently running globally, according to the Atlantic Council CBDC Tracker.

Could a CBDC replace cash?

Most central banks — including the ECB — explicitly state their CBDC is designed to complement cash rather than replace it. The ECB has confirmed it will continue issuing physical banknotes alongside any digital euro. However, critics argue that if CBDC adoption becomes widespread and cash usage continues declining, the practical ability to transact anonymously could disappear even without a formal cash ban — making the "complement not replace" framing partly aspirational.

Sources and Further Reading

The central bank digital currency race is not a future scenario — it is already underway, with real money moving across real borders on systems that did not exist five years ago. The US has opted out of building its own CBDC, betting instead that dollar-backed stablecoins can preserve dollar dominance in a digital age. Meanwhile, China's e-CNY is already settling hundreds of billions of dollars in trade through mBridge outside the dollar correspondent system. Whether the GENIUS Act stablecoin strategy proves sufficient to maintain the dollar's global role against state-backed digital currencies is the question that will define monetary geopolitics for the next generation. For the full context on what dollar dominance means and why it matters, see [What Is a Reserve Currency? How the Dollar Became Global Money] and [The Petrodollar System Explained].
