In November 2021, during Hong Kong FinTech Week, the multilateral central bank digital currency (mCBDC) bridge project released its use case handbook. This initiative, supported by the Bank for International Settlements Innovation Hub Hong Kong Centre, was jointly launched by the Hong Kong Monetary Authority, the Bank of Thailand, the Central Bank of the United Arab Emirates, and the Digital Currency Institute of the People's Bank of China. A significant milestone was the participation of 22 financial institutions in subsequent testing phases, showcasing global collaboration in exploring the potential of digital currencies for international settlements.
Understanding Digital Currency and Its Key Concepts
Digital Currency Electronic Payment (DCEP) is a legal digital currency under research and development by the People's Bank of China. Issued by the central bank and operated by designated institutions, it is exchangeable to the public. Based on a broad account system, it supports loosely coupled bank account functionality. It holds equivalent value to physical cash and coins, featuring value characteristics and legal compensability with controlled anonymity.
Digital currency operates without reliance on a specific monetary issuing institution. Instead, it is generated through complex algorithms based on digital principles, existing as a form of virtual network currency. Without a central issuing body and with a fixed number of algorithmic solutions, the total supply of such digital currencies remains constant. This inherently eliminates the possibility of inflation caused by excessive issuance of virtual currency. Moreover, as transaction processes require validation by various network nodes, digital currency transactions are highly secure.
Comparing Digital Currency, Electronic Money, and Virtual Currency
- Sovereign Legal Digital Currency: Issued by a state and legally recognized as having primary currency status, e.g., China's DC/EP.
- Private Digital Currency: Issued by institutions or alliances, such as Facebook's Libra (now Diem).
- Digital Currency on Public Chains: Characterized by decentralization, unlike sovereign and private digital currencies which are issued by a specific central entity.
- Electronic Money: Essentially an electronic form of legal tender banknotes.
- Virtual Currency: Specialized currency issued by websites or communication service providers for purchasing services within their ecosystem.
The Dual-Layer Operation System of DC/EP
DC/EP adopts a dual-layer operation system. The central bank first exchanges the digital currency to commercial banks or other operating institutions, which then distribute it to the public. This forms a two-tier distribution system with the central bank at the upper level and commercial banks at the second level.
This system offers triple advantages:
- It fully utilizes the IT infrastructure, talent reserves, and technical研发 capabilities of financial institutions like commercial banks for joint currency development and operation.
- Compared to a single-layer operation, collaboration between the central bank and numerous commercial banks disperses the research, development, and operational risks of the DC/EP system.
- Under a single-layer structure, a central bank-backed DC/EP could crowd out commercial bank deposit money, reducing their ability to absorb deposits. This would increase reliance on interbank markets, raising funding costs, increasing social financing expenses, and potentially leading to financial disintermediation.
The Significance of Digital Currency Adoption in China
The unique characteristics of digital currency—such as controlled anonymity, traceability, and programmability—enable the central bank to monitor its circulation effectively. This enhances the调控效果 of monetary circulation. Through centralized management by the central bank, it can provide support in areas like targeted loans, capital allocation, anti-corruption, and anti-money laundering efforts.

The promotion of digital currency brings new market growth. The issuance of digital currency in China is being gradually implemented. Positioned as M0 currency (physical cash in circulation), it revolves around the central bank's centralized management. Upon issuance, it can improve the efficiency of monitoring monetary operation, enrich monetary policy tools, and enhance the intelligent management of currency circulation. Furthermore, it can significantly increase the efficiency of cross-border payments, establish an open payment environment, and lay the groundwork for the globalization of the Renminbi.
In the long term, the promotion of digital currency is a powerful driver for the bank IT solutions market. This includes the central bank's main digital currency system, clearing agencies' digital currency清算 systems, internal digital currency systems within commercial banks, and the integration of digital currency with other bank IT systems. These implementations, primarily carried out by bank IT solution providers, are expected to generate incremental demand in the bank IT market.
Regulatory Stance and Policy Direction
On July 31, 2021, the People's Bank of China held a work conference for the second half of the year. The meeting emphasized promoting the standardized development of financial businesses within platform enterprises and cracking down on illegal activities involving virtual currency. The central bank, in conjunction with other departments, resolutely implements the decisions and deployments of the Party Central Committee and the State Council regarding anti-monopoly and preventing the disorderly expansion of capital. This has included interviewing leading platform enterprises engaged in financial businesses, urging them to fully comply with requirements related to financial regulation, fair competition, and consumer rights protection, and to conduct in-depth self-inspections and rectifications.
The Chinese central bank's attitude towards digital currency is clear: focus on the real economy, actively promote blockchain infrastructure construction and the development of the digital Renminbi, while restricting other cryptocurrencies. To ensure that non-legal digital currencies do not disrupt the domestic financial environment, the central bank has imposed trading restrictions on a series of cryptocurrencies represented by Bitcoin and extended these restrictions to initial coin offering (ICO) processes.
Frequently Asked Questions
What is the mCBDC Bridge project?
The mCBDC Bridge is a collaborative research project exploring the use of multiple central bank digital currencies for cross-border payments. It aims to enhance the efficiency and reduce the costs of international settlements by leveraging digital currency technology.
How does China's DC/EP differ from cryptocurrencies like Bitcoin?
DC/EP is a centralized, state-backed legal tender with controlled anonymity, issued by the People's Bank of China. In contrast, Bitcoin is a decentralized cryptocurrency with no central issuing authority, known for its full anonymity and volatility. DC/EP is designed for everyday transactions and monetary stability.
What are the benefits of the dual-layer operation system?
This system leverages existing banking infrastructure, distributes operational risk, and prevents potential financial disintermediation by maintaining the role of commercial banks in deposit-taking and distribution, thus stabilizing the broader financial system.
Why is traceability important in a digital currency?
Traceability allows the central bank to monitor money flow, which aids in implementing monetary policy, combating financial crimes like money laundering and fraud, and ensuring the proper allocation of funds within the economy.
How might digital currency impact cross-border payments?
Digital currencies like those tested in the mCBDC bridge can streamline cross-border transactions by reducing intermediary steps, lowering transaction fees, decreasing settlement times from days to seconds, and increasing transparency throughout the process.
Is the digital Renminbi (DC/EP) mandatory?
No, the digital Renminbi is not mandatory. It is designed to coexist with physical cash (M0) and provide an additional, convenient, and secure payment option for the public. It is legally equivalent to physical RMB.
