The year 2020 marked a pivotal milestone in the evolution of central bank digital currencies (CBDCs), as nations worldwide accelerated research and development in response to the growing influence of private digital currencies. Among them, China has emerged as a frontrunner, advancing rapidly from theoretical exploration to real-world pilot programs. The term "digital yuan" ranked sixth among China’s top ten new media buzzwords in 2020—highlighting its rising prominence in public discourse and policy agendas.
As mobile payments dominate daily transactions across urban China, the People's Bank of China (PBOC) introduced its official digital currency, known as Digital Currency/Electronic Payment (DC/EP), to modernize the financial system while maintaining state oversight. Unlike commercial payment platforms such as Alipay and WeChat Pay, the digital yuan is legal tender backed by national credit, designed to coexist with physical cash while offering enhanced functionality for a cashless society.
Why Central Banks Are Embracing Digital Currencies
Private cryptocurrencies like Bitcoin and Litecoin, built on distributed ledger technology (DLT) and cryptographic security, have gained traction as decentralized alternatives to traditional money. These systems operate without central control or intermediaries, enabling peer-to-peer transactions with pseudonymity and low fees. However, their unregulated nature poses risks—ranging from money laundering and terrorist financing to challenges in monetary sovereignty.
In response, over 80% of central banks globally are now exploring CBDCs, according to a 2019 Bank for International Settlements (BIS) survey. While many remain in early research phases, China stands out for transitioning into live testing. Since April 2020, DC/EP has undergone closed trials in Shenzhen, Suzhou, Xiongan New Area, and Chengdu—expanding later to key economic zones including the Greater Bay Area, Beijing-Tianjin-Hebei, and Yangtze River Delta.

How Digital Yuan Differs From Mobile Payment Apps
Despite superficial similarities, the digital yuan fundamentally differs from existing electronic wallets:
- Legal Status: It is sovereign currency issued by the PBOC, equivalent in value to physical RMB.
- Credit Backing: While Alipay and WeChat rely on corporate credit, DC/EP is backed by full state guarantee.
- Offline Functionality: A key innovation is dual offline payments—two smartphones can transfer funds via NFC even without internet connectivity, mimicking cash handovers.
- Interoperability: Designed to break down payment silos between platforms, it enables seamless fund circulation across institutions.
These features position DC/EP not merely as an upgrade to current e-payments but as a foundational shift toward a more inclusive and resilient financial ecosystem.
Dual-Layer Architecture and Controlled Anonymity
China’s CBDC adopts a two-tier operational model:
- The PBOC issues digital currency to commercial banks.
- Banks distribute it to individuals through digital wallets.
This structure preserves the existing banking framework, minimizing disruption while incentivizing bank participation.
Moreover, DC/EP implements tiered identity verification:
- Small transactions: Allow limited anonymity for privacy protection.
- Large transfers: Require full KYC compliance to prevent illicit use.
This “light-touch anonymity” balances user privacy with regulatory oversight—an approach other nations may emulate.
Pilot Successes and Real-World Applications
Early pilots demonstrated strong public engagement:
- In Shenzhen, a digital red envelope giveaway attracted over 475,000 participants and generated RMB 8.76 million in transactions across 3,389 merchants.
- Suzhou extended trials to online shopping during its “Double 12” festival, distributing 100,000 digital coupons worth RMB 20 million.
Beyond consumer spending, the PBOC tested targeted monetary policies—issuing transport subsidies in digital form to specific government employees—showcasing potential for precise fiscal stimulus.
Hong Kong’s Strategic Role in Cross-Border Expansion
As the world’s largest offshore RMB hub and a global financial center, Hong Kong plays a crucial role in the internationalization of DC/EP. The Hong Kong Monetary Authority (HKMA) is collaborating with the PBOC’s Digital Currency Research Institute to explore cross-border payment applications.
Potential synergies include:
- Integrating DC/EP with Hong Kong’s Faster Payment System (FPS) for instant cross-border retail transfers.
- Facilitating easier travel-related spending between mainland tourists and Hong Kong residents.
- Supporting RMB liquidity within the Greater Bay Area and creating new channels for capital flow.
Given its unique "one country, two systems" status, Hong Kong serves as a secure testing ground—balancing openness with regulatory control.

Geopolitical Implications and Financial Sovereignty
Beyond domestic modernization, DC/EP holds strategic significance amid rising U.S.-China tensions. With Washington wielding influence over SWIFT and global dollar clearing systems, Beijing views digital currency as a tool to reduce dependency on Western-dominated financial infrastructure.
By enabling direct cross-border settlements using digital RMB, China could:
- Strengthen RMB internationalization.
- Create alternative payment corridors resilient to sanctions.
- Influence future global CBDC standards.
President Xi Jinping emphasized this vision at the G20 summit in 2020, calling for inclusive dialogue on CBDC frameworks that promote shared progress in the international monetary system.
Global CBDC Progress Snapshot
While China leads in implementation, other economies are advancing steadily:
- Sweden: Testing e-krona for broad financial inclusion.
- Singapore: Completed multi-currency settlement trials under Project Ubin.
- Japan & EU: Jointly researching interoperability through Project Stella.
- Thailand & Hong Kong: Collaborating on blockchain-based cross-border settlements.
Yet none have matched China’s scale of real-world deployment.
Frequently Asked Questions (FAQ)
Q: Is digital yuan the same as cryptocurrency like Bitcoin?
A: No. Digital yuan is a centralized, state-issued legal tender with regulated oversight. Bitcoin is decentralized and operates independently of governments.
Q: Can I use digital yuan outside China?
A: Not yet widely, but pilot programs involving Hong Kong and select trade partners are underway to test cross-border usability.
Q: Does digital yuan threaten privacy?
A: It offers "controlled anonymity"—small transactions remain private, but large transfers are traceable to comply with anti-money laundering rules.
Q: Will digital yuan replace cash?
A: Not immediately. It complements physical currency and aims to enhance financial efficiency rather than eliminate cash entirely.
Q: How does DC/EP benefit everyday users?
A: It provides faster, cheaper transactions; supports offline payments; increases payment choice; and enhances access to government services and subsidies.
Q: Are private payment apps like Alipay at risk?
A: Not directly. They will likely integrate DC/EP into their platforms, serving as distribution channels rather than competitors.
The Road Ahead
China’s head start in CBDC development positions it to shape global norms in digital finance. With continued testing in high-profile settings—including the Winter Olympics—and growing regional cooperation via Hong Kong, the digital yuan could become a blueprint for future monetary systems.
As central banks worldwide navigate this transformation, lessons from China’s phased rollout—balancing innovation with stability, privacy with accountability—will be closely watched.
