Case Study 1: China's Digital Yuan — 260 Million Wallets and $250 Billion in Transactions — But Is Anyone Using It Voluntarily?
Background: The World's Largest CBDC Experiment
When the People's Bank of China (PBOC) began publicly piloting the digital yuan — officially designated e-CNY — in late 2019, it was the most ambitious experiment in digital currency ever attempted by a sovereign nation. By 2024, the numbers looked staggering by any measure. Over 260 million individual wallets had been created. Cumulative transactions had surpassed 7 trillion yuan (approximately $980 billion). The pilot covered 26 provinces and cities, spanning everything from Shenzhen's tech-forward consumer economy to rural regions in western China. Government salaries were being paid in e-CNY. Subway systems accepted it. Vending machines dispensed drinks for it. The 2022 Beijing Winter Olympics served as a high-profile showcase, with foreign visitors able to use e-CNY through temporary wallets.
These are the numbers that policymakers and journalists typically cite. They paint a picture of a digital currency that has achieved remarkable adoption in just a few years. The reality on the ground, however, tells a more complicated story — one that reveals fundamental challenges facing every retail CBDC project worldwide.
The Adoption Puzzle
Headline Numbers vs. Active Usage
The 260 million wallet figure requires context. During the pilot phase, the PBOC and partner commercial banks conducted dozens of promotional campaigns in pilot cities. In the most common format, the government distributed "red envelopes" (digital hongbao) — free e-CNY, typically 50-200 yuan ($7-$28) per person — to randomly selected residents who downloaded the e-CNY app and created a wallet. In Shenzhen's first major pilot in October 2020, 50,000 residents were selected from 1.9 million applicants to receive 200-yuan red envelopes. Each subsequent pilot city ran similar campaigns.
These campaigns were wildly successful at generating wallet registrations. They were far less successful at generating sustained usage. A 2023 survey by Peking University's Digital Finance Research Center found that while awareness of the e-CNY exceeded 80% in pilot cities, regular use (defined as at least one transaction per month) was below 10%. The majority of wallets created during promotional campaigns showed little or no activity after the promotional balance was spent.
The reason is straightforward: in China's payment landscape, the e-CNY is not solving a problem that users experience. The two dominant mobile payment platforms — Alipay (operated by Ant Group, an Alibaba affiliate) and WeChat Pay (operated by Tencent) — collectively process over $30 trillion in annual transactions and are used by more than a billion people. These platforms are deeply integrated into Chinese daily life: social media, ride-hailing, food delivery, bill payments, investment products, and peer-to-peer transfers all flow through Alipay and WeChat Pay. The user experience is polished after more than a decade of iteration. Switching to e-CNY for payments requires downloading a separate app, linking a bank account, and forgoing the integrated ecosystem features that Alipay and WeChat Pay provide.
The Convenience Gap
Several specific usability gaps have been documented by Chinese technology journalists and researchers:
Merchant integration. While the number of merchants accepting e-CNY grew rapidly (exceeding 5.6 million by mid-2023), many merchants reported that e-CNY transactions comprised a tiny fraction of their business. Merchants that accepted e-CNY typically also accepted Alipay and WeChat Pay, and customers overwhelmingly chose the latter because they were already integrated into their daily routines.
Ecosystem fragmentation. Alipay and WeChat Pay are not just payment platforms. They are ecosystems. WeChat Pay is embedded in WeChat — the app that 1.2 billion Chinese people use for messaging, social media, and daily communication. Paying through WeChat Pay requires no context-switching; you are already in the app. Using e-CNY requires opening a separate application, which is a small friction that nonetheless dramatically reduces usage rates.
Reward programs. Alipay and WeChat Pay offer loyalty points, cashback, merchant discounts, and integration with investment products (like Ant Group's Yu'e Bao money market fund, which at one point managed over $250 billion). The e-CNY offers none of these. For a rational consumer, using e-CNY instead of Alipay means giving up tangible financial benefits.
Social features. WeChat's red envelope feature — sending money to friends during holidays and celebrations — is a cultural institution in digital China, with billions of red envelopes exchanged during Chinese New Year alone. The e-CNY's red envelope feature is a promotional tool, not a social one. The emotional and social resonance is absent.
The Government Push
Where Adoption Is Not Voluntary
The areas where e-CNY transaction volumes are highest are, disproportionately, areas where usage is not entirely voluntary:
Government salary payments. Several pilot city governments began paying portions of civil servant salaries in e-CNY. In Changshu (Jiangsu province), the city government announced in 2023 that all civil servants would receive their full salaries in e-CNY starting in May. Workers could immediately transfer the funds to their bank accounts, but the initial receipt was in e-CNY. This generated significant transaction volume but told nothing about voluntary demand.
Public transportation. E-CNY was integrated into subway and bus systems in pilot cities, sometimes with small discounts for e-CNY users. Transportation is a high-frequency, low-value use case that inflates transaction counts without reflecting broad commercial adoption.
Government subsidy disbursement. Pandemic-related subsidies, consumer vouchers, and local government benefits were increasingly disbursed through e-CNY, creating transaction volume but not user preference.
Tax payments. Several pilot cities enabled tax payments through e-CNY, creating high-value transactions that boosted volume figures.
The Policy Objective Behind the Push
The PBOC has been explicit that the e-CNY is not intended to replace Alipay and WeChat Pay in the short term. In speeches and policy documents, PBOC officials have framed the e-CNY as serving several strategic purposes that do not require mass voluntary consumer adoption:
Breaking platform monopolies. Alipay and WeChat Pay constitute a duopoly over Chinese digital payments. The PBOC has regulatory concerns about this concentration — particularly after Ant Group's planned IPO was blocked in 2020 amid regulatory scrutiny. A government-issued digital currency provides a public infrastructure alternative, reducing dependence on two private-sector platforms.
Financial inclusion. Despite China's high mobile payment penetration, approximately 40 million rural Chinese adults remain outside the digital payment system. The e-CNY's tiered wallet system (with the lowest tier requiring only a phone number) and offline payment capability are designed for this population, even though urban pilot metrics dominate the headlines.
Cross-border ambitions. The e-CNY's role in Project mBridge and bilateral trade settlement experiments with Thailand, the UAE, and Saudi Arabia suggests a long-term geopolitical strategy that is independent of domestic consumer adoption metrics.
Monetary sovereignty. The PBOC wants to ensure that the central bank — not private technology companies — controls the foundational layer of the digital payment system. Even if consumers continue to use Alipay and WeChat Pay for daily transactions, the PBOC envisions a future where those platforms settle through e-CNY infrastructure, giving the central bank a position at the base of the payment stack.
The Surveillance Dimension
What We Know
The e-CNY system is designed with "controllable anonymity," which the PBOC defines as follows: transactions are anonymous to the commercial banks and merchants involved (at the lowest wallet tier), but the PBOC retains the ability to trace any transaction. The system is architecturally capable of providing the PBOC with:
- The identity of every wallet holder (at least above the lowest tier)
- The full transaction history of every wallet
- Real-time visibility into payment flows across the economy
- The ability to freeze or restrict any wallet
The PBOC has described these capabilities as essential for anti-money-laundering, counter-terrorism financing, and tax compliance. Officials have emphasized that user privacy is protected from commercial exploitation — merchants and banks cannot access granular transaction data — and that PBOC access to individual data requires authorized procedures.
What We Don't Know
Critical details about the e-CNY's surveillance infrastructure remain opaque:
What constitutes "authorized procedures"? The PBOC has not published detailed rules governing when and how its staff can access individual transaction data. In a country without an independent judiciary or comprehensive privacy legislation (China's Personal Information Protection Law, enacted in 2021, includes broad exemptions for government agencies), the practical constraints on surveillance are uncertain.
Is the data centralized? Whether the PBOC maintains a single centralized transaction database (a honeypot for cyberattack and internal abuse) or distributes the data across compartmentalized systems has not been publicly disclosed.
What is shared with other agencies? The extent to which e-CNY transaction data is shared with the Public Security Bureau (police), the State Administration of Taxation, or the various regional Social Credit System implementations is unknown.
What about the lowest-tier "anonymous" wallets? The PBOC states that wallets opened with only a phone number provide anonymity. But phone numbers in China are registered with real names (real-name registration has been mandatory since 2010). "Anonymous to the wallet, identified by the phone number" is not the same as "anonymous."
Analysis: What Does the e-CNY Tell Us About CBDCs?
Lesson 1: Adoption Cannot Be Assumed
The e-CNY's adoption challenges are not a failure of technology. The technology works. The challenge is that a CBDC competes with existing payment infrastructure, and in countries with mature digital payment ecosystems, the incumbent platforms have overwhelming advantages in user experience, network effects, and integrated services. This lesson applies directly to the digital euro (which would compete with well-established bank payment apps across Europe) and to any hypothetical US CBDC (which would compete with debit cards, Venmo, Zelle, Apple Pay, and Google Pay).
Lesson 2: Government Mandate Can Generate Volume, Not Loyalty
China's ability to generate transaction volume by paying government salaries in e-CNY and disbursing subsidies through the platform demonstrates that government mandate can create usage. But mandated usage and voluntary usage are categorically different. Mandated usage tells you about government power; voluntary usage tells you about product-market fit. The e-CNY has demonstrated the former but not the latter.
Lesson 3: The Surveillance Architecture Exists Regardless of Current Use
Whether or not the PBOC currently uses the e-CNY for mass surveillance, the architecture supports it. This matters because surveillance architectures tend to be used to their full capacity over time. Powers created for one purpose are repurposed for others. A system designed for AML compliance can be repurposed for political control with minimal technical modification. The existence of the capability, not its current use, is the relevant consideration for evaluating the surveillance risk.
Lesson 4: Strategic Value May Exceed Consumer Value
The e-CNY's greatest value may not be as a consumer payment tool but as a strategic infrastructure play — breaking private-sector payment monopolies, enabling cross-border settlement outside the dollar system, and positioning the central bank at the foundation of the digital economy. If this is the true objective, then the consumer adoption metrics that dominate headlines are measuring the wrong thing.
Questions for Discussion
-
The e-CNY had over 260 million wallets but less than 10% regular usage. At what threshold does a CBDC pilot become a success? Is wallet creation, transaction volume, voluntary usage rate, or some other metric the most meaningful measure?
-
In China, the government can mandate e-CNY usage through salary payments and subsidy disbursement. Should other countries adopt this strategy, or does mandated usage undermine the legitimacy of a CBDC?
-
The PBOC frames controllable anonymity as a balance between privacy and law enforcement. Under what conditions, if any, should a central bank have the ability to trace individual transactions? Who should authorize access — a court, a regulatory body, or the central bank itself?
-
If the e-CNY's primary strategic value is breaking the Alipay/WeChat Pay duopoly and enabling cross-border settlement, is this a legitimate use of a CBDC? Or is creating a national digital currency to solve industrial policy and geopolitical problems a misuse of monetary tools?
-
Consider the perspective of a Chinese citizen who values financial privacy. Are they better off with Alipay (a private company subject to government regulation) or with the e-CNY (a government system with built-in surveillance capability)? Does the answer change depending on the citizen's relationship with the government?
