What is CBDC, Central Bank Digital Currency

What Is CBDC?

A Central Bank Digital Currency (CBDC) is a digital currency issued by a central bank—sometimes called a national cryptocurrency. CBDCs act as a digital counterpart to sovereign currency, combining the strengths of traditional money with the benefits of modern technology. For example, instead of a traditional dollar, the central bank could issue a crypto version that preserves all the properties of fiat currency but operates digitally.

Central bank experts worldwide believe CBDCs effectively blend the features of fiat and electronic money. CBDCs provide a financial instrument that delivers the reliability of government-backed funds and the convenience of digital payments. They can serve as a bridge between the legacy financial system and the evolving digital economy.

CBDC Functions

There are multiple models for issuing a national cryptocurrency, each with unique implications for a country’s economy:

1. CBDC as a cash replacement. Users transition from physical cash to a more convenient digital alternative. In this scenario, CBDC functions as a digital substitute for paper notes and coins. Introducing such digital money has little impact on monetary policy since it only replaces the physical form, keeping all other attributes intact.

2. CBDC as an alternative to payment systems. Paying for goods and services becomes easier with direct user-to-user transactions through the central bank’s system. The central bank would assume a much larger role in the payments market as the main provider of payment infrastructure—potentially reducing the importance of traditional payment systems and intermediary banks.

3. CBDC as a substitute for deposits. Citizens could hold their savings directly in CBDC accounts at the central bank. This is the most transformative scenario, requiring significant changes to monetary policy and the banking sector. Commercial banks could lose a major share of deposits, which may affect their lending capacity.

How Is CBDC Different from Fiat?

Like fiat, a CBDC is issued by the central bank, ensuring trust and stability. However, unlike traditional currency, all CBDC transactions can be digital, opening new opportunities for the financial system.

CBDC Advantages Compared to Fiat:

• Lower operational costs. Digital money eliminates the need for printing, transportation, storage, and protection—substantially reducing costs for both the public and private sectors.

• Faster transactions. Digital payments can be nearly instantaneous, without delays typical of legacy banking systems.

• Enhanced payment system performance through automation. Automation reduces errors, accelerates payment processing, and lowers transaction costs.

CBDCs equip regulators to more efficiently oversee the flow of funds and monitor monetary movements across the economy. This can help combat money laundering, terrorism financing, and other financial crimes. At the same time, CBDCs increase financial system transparency and allow central banks to react more quickly to economic shifts.

How CBDC Differs from Decentralized Cryptocurrencies

The central bank issues and fully controls CBDC—managing its supply, usage rules, and interventions when needed. This makes CBDC a centralized system governed by a state regulator.

Decentralized cryptocurrencies (like Bitcoin or Ethereum) exist outside the direct control of any financial regulator. They run on distributed networks where no single participant holds total authority. This independence from state institutions poses both regulatory challenges and user protection concerns.

The core difference: CBDC is a government authority’s regulated instrument, while decentralized cryptocurrencies operate independently from state oversight.

CBDC Security

CBDCs are considered safer than fiat money because they’re harder to counterfeit. Their digital nature—combined with modern cryptographic protections—makes forgery nearly impossible. However, security depends heavily on technical implementation and platform selection.

When based on blockchain technology, CBDC security is robust. Blockchain provides immutable records, transparent transactions, and distributed data storage, making malicious actions substantially more difficult. Every transaction is recorded in a distributed ledger, which is virtually impossible to alter without detection.

Still, CBDC security also depends on the protection of users’ digital wallets, central bank infrastructure, and data transmission protocols. Cybersecurity is a critical factor for the successful rollout of national digital currencies.

Which Countries Are Developing CBDCs?

In recent years, many countries have started working on national digital currencies. According to media reports, at least 18 countries are actively developing national cryptocurrencies, and around 60 central banks worldwide are exploring CBDC opportunities. This signals a global interest in the technology and its potential to reshape the financial system.

Interest in CBDC is driven by several factors: advances in digital technology, declining cash usage, the rise of private cryptocurrencies, and the need to modernize payment systems. Countries want to stay technologically competitive and maintain control over their monetary systems.

European Developments

Europe is actively researching CBDC issuance and studying the potential benefits and risks. The European Central Bank sees the digital euro as a tool to support the digital economy and preserve the sovereignty of the European financial system.

Digital euro pilot tests have been conducted with central banks in several European countries, including France. European regulators focus on privacy, security, and the impact on the banking sector. Their aim is to design a CBDC that fuses innovation with the core values of Europe’s financial system.

China Leads the CBDC Race

China is closest to a full-scale CBDC launch. The country’s project, called DCEP (Digital Currency Electronic Payment), is an ambitious effort to create a true digital alternative to the cash yuan.

China’s cryptocurrency could launch soon. According to China Daily, work on the digital yuan has accelerated amid global economic challenges and the need to modernize the nation’s payment infrastructure. China sees CBDC as a tool to internationalize the yuan and reduce dollar dependence in global settlements.

To launch its national cryptocurrency, the People’s Bank of China enlisted four state-owned banks:

1. Agricultural Bank of China
2. Industrial and Commercial Bank of China
3. Bank of China
4. China Construction Bank

These banks participate in pilot programs and digital yuan testing across various regions. They play a leading role in deploying CBDC and integrating it with the existing financial system.

How China’s Cryptocurrency Works

DCEP network transaction data is encrypted for high security. Users can maintain a certain level of anonymity—although not complete anonymity as with decentralized cryptocurrencies.

DCEP is designed to balance user privacy with regulatory oversight capabilities for anti-crime and compliance purposes. This is accomplished through a multi-tiered system for transaction information access.

China–US Competition

Once China started actively developing a national cryptocurrency, other central banks began considering similar initiatives—sparking a race to launch CBDC first.

Researchers believe that whichever country launches a fully functional national cryptocurrency first will gain significant competitive advantages and could lead in setting new digital finance standards. This is especially critical amid geopolitical competition between major economies.

The US is concerned that a digital yuan could weaken the dollar’s position as the global reserve currency and give China additional tools for influence in international trade and finance.

US Alternatives to Libra

In response, the US established a Digital Dollar Project, led by former Commodity Futures Trading Commission Chairman Christopher Giancarlo. The project explores the feasibility and roadmap for a US digital dollar.

At the same time, the US is considering other responses to China’s CBDC—such as the FedNow payment system and upgrades to existing financial infrastructure. US regulators are cautious, weighing all potential risks and benefits of CBDC adoption.

Russia’s Stance on CBDC

Bank of Russia experts remain cautious about adopting CBDC. They believe the country can forgo a full-scale national cryptocurrency by modernizing the current financial system instead.

Russia may opt to strengthen its fiat currency with digital capabilities, such as the Fast Payment System (FPS) launched in recent years. The FPS enables instant interbank transfers and may meet demand for fast digital payments without requiring a full CBDC.

However, Russia continues to monitor CBDC developments elsewhere and may reconsider its position if central bank digital currencies become the global norm.

Key Takeaways

Here are the main points on CBDCs:

• CBDCs are highly centralized compared to decentralized cryptocurrencies. This makes them more predictable and controllable for regulators, but less independent than classic crypto assets.

• Digital currencies deliver faster, cheaper, and more secure transactions than fiat. CBDCs streamline financial system operations and reduce the cost of money circulation.

• CBDCs can be designed for user anonymity. The extent of privacy depends on technical design and regulatory policy. Some countries plan to provide a degree of user confidentiality.

• Adoption of national digital currencies will make it easier for central banks to monitor money flows. This can improve monetary policy effectiveness and support crime prevention efforts.

• CBDCs offer multiple use cases. The chosen model will shape a country’s monetary policy and financial system structure. Each country can select a CBDC approach tailored to its own needs and economy.
