What Is a Central Bank Digital Currency (CBDC)?
A Central Bank Digital Currency is the digital form of a country’s national currency, issued and regulated by its central bank. It represents legal tender in electronic format—not a new currency, but a new representation of existing money. Like physical cash, CBDCs are direct liabilities of the central bank and carry full state backing.
The key feature that sets CBDCs apart from the balance in a regular online bank account is that CBDC funds originate directly from the central bank’s own balance sheet, rather than from a commercial institution. This provides a higher degree of security, neutrality, and stability—particularly valuable during financial crises when confidence in private intermediaries may weaken.
CBDCs stand in stark contrast to cryptocurrencies. While Bitcoin and Ethereum operate on decentralized, permissionless networks, CBDCs are centrally issued, governed by domestic law, and fully regulated. Their value is pegged to the national fiat currency, making them suitable for daily transactions, salary payments, and savings without the price swings common in crypto markets. The goal is to modernize public money by offering a digital version of cash that is accessible, efficient, and universally accepted.
Dozens of countries are actively exploring CBDCs. China’s digital yuan (e-CNY) is in large-scale public trials. The Swedish central bank is piloting the e-Krona. The European Central Bank is working on a digital euro, and in 2022 the US Federal Reserve released discussion papers on a possible digital dollar. However, the US CBDC process effectively stalled in early 2025. In January 2025, the White House issued an executive order titled “Strengthening American Leadership in Digital Financial Technology,” prohibiting federal agencies from establishing or promoting a CBDC, and requiring explicit congressional authorization for any future efforts. This was followed in July 2025 by the US House of Representatives passing the Anti-CBDC Surveillance State Act, which would block the Federal Reserve from developing, testing, or issuing a CBDC without congressional approval and forbid using a CBDC for monetary policy or surveillance purposes. The bill now awaits Senate consideration.
How Do CBDCs Work?
To users, paying with a CBDC may feel similar to using a mobile banking app or digital wallet, but the underlying infrastructure is fundamentally different. At the center of the system sits the national central bank, which issues the digital currency and maintains the authoritative ledger. Some CBDC projects use blockchain or distributed ledger technology, while others rely on traditional database architectures reinforced with multiple security layers.
Access is provided through digital wallets. These wallets can be issued directly by the central bank, by commercial banks, or by licensed third-party providers. Individuals and businesses use the wallet to receive, store, and transfer CBDC just as they would with existing mobile money services.
CBDCs are designed along two main models: account-based and token-based. In the account-based model, users must verify their identity to open and use a wallet, and all transactions are tied to specific identities—much like a bank account. Token-based CBDCs, by contrast, function more like physical banknotes: the digital tokens themselves embody value, and whoever holds the token effectively owns it, often without requiring continuous identity linking at the point of each transaction.
A typical CBDC transaction follows these steps:
- Funds are deposited into your CBDC digital wallet.
- You use the wallet app to pay a merchant or send money to another person.
- The transaction is verified and settled on a central ledger operated by or under the supervision of the central bank.
- Once settled, the recipient’s wallet instantly reflects the new balance.
Many CBDC designs also incorporate offline capabilities, enabling device-to-device payments without an active internet connection. Others are exploring programmable features—for instance, funds that can only be spent on certain categories of goods, or that automatically expire—which governments may use for targeted stimulus payments or welfare distribution. These programmable characteristics, while promising, also prompt debate about civil liberties and monetary freedom.
What Is the Purpose of CBDCs?
Central banks and governments pursue CBDCs for a combination of economic, technological, and strategic reasons.
Enhancing payment efficiency is a primary motivation. In many economies, payment rails remain slow, fragmented, and costly, especially for cross-border transfers. A CBDC built on modernized infrastructure can enable near-instant, low-cost settlement for both domestic and international transactions, ultimately improving access for households and small businesses.
Financial inclusion is another central goal. Globally, hundreds of millions of adults lack access to a transaction account at a bank or regulated non-bank provider. By offering a digital currency that can be held and transacted via a basic mobile phone—without requiring a traditional bank account—CBDCs can draw unbanked populations into the formal financial system, helping them safely store value, make digital payments, and receive government transfers.
CBDCs also provide central banks with new tools for implementing monetary policy and facilitating fiscal transfers. They can, for instance, enable more direct transmission of policy rate changes to retail depositors, or support targeted, rapid disbursement of social benefits and disaster relief.
From a strategic perspective, CBDCs are a proactive answer to the rise of private digital payments and stablecoins. Central banks are defending monetary sovereignty and attempting to preserve public trust in fiat currencies within an increasingly digital economy. Additionally, by reducing the need to print, transport, and store physical cash, CBDCs offer the prospect of long-term cost savings, particularly in nations already moving toward cashless societies.
Benefits of CBDCs
CBDCs can deliver meaningful advantages to users, financial institutions, and governments alike.
For everyday users, the most tangible benefit is faster, lower-cost payments. Sending money to a friend, paying a bill, or receiving a salary could all settle in seconds with minimal fees. This is especially transformative in countries where domestic remittances are slow and expensive.
Security and transparency are further strengths. Each transaction is verifiable on the central ledger, making it significantly harder for illicit activity to pass unnoticed. While full anonymity is unlikely, most CBDC designs seek to preserve reasonable privacy within legal and regulatory guardrails.
CBDCs also offer greater system resilience. Private payment platforms can experience outages, operational failures, or even shut down. A central bank-operated digital currency provides a public, always-on payment rail that remains available even if individual banks or apps fail.
For governments, CBDCs sharpen the effectiveness of monetary and fiscal policy. They can facilitate targeted transfers, support new interest rate mechanisms, and generate more accurate, timely economic data. For commercial players—banks, fintech firms, and technology providers—CBDCs open new avenues for innovation. Wallets, compliance tools, data analytics, and credit products can all be built atop CBDC infrastructure, fostering a more dynamic financial ecosystem.
Types of CBDCs
CBDCs generally fall into two categories: retail CBDCs and wholesale CBDCs, each serving distinct purposes and audiences.
1. Retail CBDCs
Retail CBDCs are designed for the general public—individuals, households, and businesses. They work like digital banknotes: users hold funds in a wallet and can spend them at points of sale or transfer them to other individuals. Wallets may be provided by commercial banks, the central bank itself, or approved non-bank providers.
The main aim of a retail CBDC is to complement or improve upon existing retail payment methods. In rural or underserved areas with limited banking infrastructure, a retail CBDC can provide a digital, government-backed alternative to cash, increasing financial access and reducing dependency on private mobile money services. The Bahamas’ Sand Dollar and China’s digital yuan both illustrate this approach—each is being tested as a tool to bring secure digital payments to a broad population.
2. Wholesale CBDCs
Wholesale CBDCs are restricted to financial institutions and are used primarily for interbank transfers, securities settlement, and cross-border payments. They aim to modernize the back-end plumbing of the financial system by enabling faster, more transparent settlement, lowering counterparty risk, and reducing operational complexity.
Projects such as Project Jura (involving French and Swiss central banks) and Singapore’s Project Ubin focus on wholesale CBDC use cases. Several central banks are also exploring hybrid models that combine retail and wholesale features, tailoring the design to national policy objectives and the existing financial market infrastructure.
CBDCs vs Cryptocurrencies: Key Differences
Although both are digital, CBDCs and cryptocurrencies fulfill fundamentally different roles in the financial system.
The defining difference is control. CBDCs are issued and governed by a central bank and represent a direct claim on the sovereign. Cryptocurrencies such as Bitcoin are decentralized, permissionless, and not backed by any government. Their value is driven by market supply and demand rather than a pegged exchange rate.
Stability is another critical point of divergence. A CBDC is valued exactly at par with the national currency—one digital dollar equals one physical dollar. Cryptocurrencies, by contrast, are notoriously volatile, making them attractive for speculation but less practical for everyday payments. Tools like Crypto.com Price allow users to compare live prices, volatility metrics, and market performance across hundreds of tokens, clearly illustrating the difference.
Privacy approaches also differ. CBDCs will almost certainly require some level of identity verification and transaction monitoring to comply with anti-money laundering and counter-terrorist financing rules. Most cryptocurrencies provide a higher degree of pseudonymity. Finally, CBDCs are deeply integrated into the regulated financial system, whereas cryptocurrencies largely operate outside traditional oversight—a fact that continues to shape the evolving regulatory debate. In the meantime, products like the Crypto.com Visa Card already bridge the two worlds by enabling users to spend digital assets at merchants worldwide.
Risks and Concerns About CBDCs
Alongside their promise, CBDCs raise serious policy, technical, and societal questions.
Privacy is arguably the top concern for the public. Cash leaves no digital footprint, but CBDC payments will almost certainly be logged. Even if user identities are masked, the central bank or other government agencies could theoretically analyze payment flows to construct detailed profiles of individual behavior. In jurisdictions with weak data protection frameworks, this raises significant civil liberties alarms.
Cybersecurity is a major operational risk. A CBDC platform that holds a nation’s retail or wholesale value represents a high-value target for hackers, state-sponsored groups, and criminals. A successful breach could undermine public confidence and trigger financial instability, forcing central banks to invest heavily in defensive and resilience capabilities.
The potential for disintermediation of commercial banks is also a live concern. If households and businesses shift large balances from bank deposits into CBDC wallets, banks could face funding pressures, lower lending capacity, and reduced credit availability. Limiting CBDC holdings, offering zero or lower interest rates on CBDC, or other design features may be necessary to mitigate this structural risk.
Other risks include excessive concentration of sensitive payment data, the chance of misuse by authorities, and the sheer technical complexity and cost of building a reliable national digital currency infrastructure. These issues require careful balancing of innovation against systemic safety.
Real-World Examples of CBDC Implementation
Several jurisdictions have moved from theory to live pilots or full deployments. Two of the most advanced are China’s digital yuan and the Bahamas’ Sand Dollar.
China’s Digital Yuan (e-CNY) is widely regarded as the most advanced CBDC initiative in the world. The People's Bank of China has rolled out large-scale trials in dozens of cities, enabling citizens to pay for public transport, retail purchases, and government services via a mobile app or physical smart card. While not yet a full national rollout, the project demonstrates how a central bank can integrate digital fiat currency into daily life at enormous scale.
The Bahamas’ Sand Dollar became the world’s first fully deployed retail CBDC when it launched in 2020. Designed to promote financial inclusion across the archipelago, the Sand Dollar can be accessed through a smartphone app or a prepaid card. It is accepted at local businesses and supports peer-to-peer transfers, aiming to serve both banked and unbanked residents—especially those in remote islands with limited physical banking presence.
What’s the Outlook for CBDCs?
The momentum behind CBDCs continues to build. More than 130 countries are now exploring or actively developing a CBDC, and over 30 have reached the pilot or launch stage.
International bodies like the IMF and the World Bank have endorsed CBDC research and development, particularly for its potential to modernize financial infrastructure and improve cross-border payments. The IMF has published technical handbooks to assist countries in evaluating design choices and risks, while the World Bank is focused on how CBDCs can broaden access to financial services in underserved regions.
In the near term, more countries are expected to launch controlled retail pilots, often running in parallel with existing payment systems. India, Brazil, and Nigeria have all initiated their own CBDC projects. The digital euro and digital pound are in advanced planning stages.
Looking further ahead, CBDCs may act as a catalyst for public-private partnerships, digital identity frameworks, and multi-currency clearing arrangements that make international transactions cheaper, faster, and more transparent. For individual users, staying informed is the best preparation. You can follow CBDC developments through authoritative sources such as the BIS, the IMF, and Crypto.com Learn, while the Crypto.com App offers real-time news, price alerts, and tools to help understand how CBDCs might interact with existing crypto and payment services.
