China's e-CNY: Five Years of Pilot Lessons
China's digital yuan — the e-CNY — began its first pilot trials in April 2020 across four cities: Shenzhen, Suzhou, Chengdu, and Xiong'an. Five years and dozens of expansion rounds later, it is by far the world's largest CBDC pilot, touching hundreds of millions of users and processing billions of yuan in transactions. What has China learned, and what does the e-CNY reveal about Beijing's strategic ambitions?
Scale and Adoption
By late 2025, the e-CNY pilot had expanded to 26 cities and regions, covering roughly 10% of China's population. The People's Bank of China (PBoC) reports over 300 million individual wallets opened and cumulative transaction volumes exceeding 1 trillion yuan (approximately $140 billion).
However, these headline numbers require careful interpretation. Wallet opening is not the same as active usage. Independent surveys suggest that a significant portion of opened wallets remain dormant, with users activating them for specific promotions or government distributions and then returning to Alipay and WeChat Pay — China's dominant payment platforms.
Technical Architecture
The e-CNY employs a two-tier operating model. The PBoC issues the digital currency to authorised intermediaries (commercial banks, telecom operators, and payment platforms), which then distribute it to end users. This design preserves the existing financial intermediary structure while giving the central bank direct oversight.
Key technical features include:
- Controlled anonymity — Small-value transactions are anonymous to the PBoC, but large transactions require identity verification. The system enables "controllable" anonymity — privacy for everyday use, traceability for anti-money laundering and tax compliance.
- Offline payments — The e-CNY supports near-field communication (NFC) payments without internet access, a feature tested extensively during the 2022 Beijing Winter Olympics.
- Smart contract programmability — Limited programmability enables conditional payments (e.g., government stimulus that can only be spent in specific sectors), though the PBoC has been cautious about expanding this to avoid disintermediating banks.
Strategic Motivations
The e-CNY serves multiple strategic objectives beyond domestic convenience:
- Monetary sovereignty — As private digital payment platforms (Alipay, WeChat Pay) became quasi-monopolistic, the e-CNY reasserts the central bank's role in the payments system.
- Internationalisation — The e-CNY is designed with cross-border functionality in mind. China has signed bilateral e-CNY agreements with Hong Kong, Thailand, the UAE, and several other Belt and Road Initiative partners, exploring use in trade settlement and tourism.
- Financial inclusion — The offline capability and low barrier to wallet opening (a phone number is sufficient for basic wallets) extend digital payment access to rural and elderly populations.
Challenges and Limitations
Despite its scale, the e-CNY faces several headwinds:
- Network effects — Alipay and WeChat Pay are deeply embedded in Chinese commerce, with hundreds of millions of merchants and users. The e-CNY offers no clear value proposition over these incumbents for most everyday transactions.
- Interest-bearing concerns — The e-CNY does not earn interest, unlike bank deposits. This limits its attractiveness as a store of value and constrains adoption beyond transactional use.
- Privacy perceptions — Despite the "controlled anonymity" framing, many users remain sceptical about the degree of government visibility into their transactions — a concern amplified by China's broader surveillance infrastructure.
Lessons for the World
The e-CNY pilot offers five critical lessons for other central banks pursuing CBDCs:
First, technology is the easy part — adoption is the hard part. Without a compelling use case that differentiates from existing digital payment options, even a well-designed CBDC can struggle for active usage.
Second, the two-tier model works. The PBoC's decision to distribute through existing intermediaries rather than competing directly with banks has preserved financial stability during the pilot.
Third, privacy is a spectrum, not a binary. The e-CNY's tiered anonymity model — full privacy for small transactions, traceability for large ones — offers a pragmatic template that other jurisdictions are studying closely.
Fourth, internationalisation requires interoperability. China's bilateral agreements with other central banks point toward a future where CBDCs connect through common standards rather than a single dominant system.
Finally, the e-CNY is not a revolution — it is an evolution. It reinforces rather than replaces the existing financial system, and its success will be measured not by wallet numbers but by whether it becomes an organic part of everyday commerce.
