The e-CNY, also called the digital renminbi or digital yuan, is the central bank digital currency (CBDC) of the People's Republic of China. It is issued by the People's Bank of China (PBoC) and forms part of the official renminbi monetary system, so one e-CNY is a direct claim on the central bank, equal in value to one yuan in banknotes. It is one of the most extensively tested retail CBDCs in the world.
The e-CNY belongs to a different category altogether from USDC, Tether (USDT) and other stablecoins created by private firms. A stablecoin is a liability of a private company backed by reserve assets; the e-CNY is a liability of the state's central bank and is legal tender in China.
History
The PBoC began researching a sovereign digital currency in 2014 and set up a dedicated digital currency research institute in 2017. Public pilots started in 2019 and 2020 in cities including Shenzhen, Suzhou, Chengdu and Xiong'an, often through lotteries that gave residents small amounts of e-CNY to spend. The pilot program was later extended to more cities and provinces and showcased at the 2022 Beijing Winter Olympics. The PBoC has published white papers describing the system's design and objectives.
How the e-CNY works
The e-CNY uses a two-tier structure. The PBoC issues e-CNY to authorized operators, mainly large commercial banks, which distribute it to the public and provide wallets, in a structure similar to how banknotes reach the public through banks. Users hold e-CNY in digital wallets, accessed through a dedicated app, banking apps or hardware such as cards, and can pay merchants, transfer to other users and convert to and from bank deposits.
Key design features described by the PBoC include:
- Tiered wallets with transaction and balance limits that rise with the level of identity verification, an approach the PBoC calls "managed anonymity." Small payments can be relatively private from merchants, while the central bank retains the ability to trace flows for anti-money laundering purposes.
- Offline payments, allowing transactions between devices without a network connection under certain conditions.
- A cash-like role: at launch, e-CNY was classified as part of M0 (currency in circulation) and paid no interest, to limit competition with bank deposits. The framework has been revised over time, so the current rules should be checked with the PBoC.
- Smart contract functions for conditional payments, an example of programmable money.
Unlike a public blockchain, the system is centrally managed, and the PBoC has said it does not rely on a single technology.
e-CNY compared with stablecoins and other money
As central bank money, the e-CNY carries no credit risk on an issuer such as a bank or stablecoin company. Bank deposits, by contrast, are commercial bank money, and stablecoins depend on the quality and accessibility of their reserves. The page on the difference between CBDCs and stablecoins explains the distinction in more detail. A related idea, the tokenized deposit, is a digital representation of a commercial bank deposit rather than central bank money.
The e-CNY also competes with China's dominant private mobile payment platforms, which already provide fast, cheap retail payments. That competition, more than any technical limitation, has shaped how quickly the e-CNY has been taken up.
Cross-border use
The e-CNY was designed mainly for domestic retail use, but the PBoC has taken part in cross-border experiments. The most prominent is mBridge, a multi-CBDC platform for wholesale cross-border payments developed with the Hong Kong Monetary Authority, the Bank of Thailand and the Central Bank of the UAE, later joined by the Saudi Central Bank. The Bank for International Settlements, which helped incubate the project, stepped back from it in 2024. Such projects are seen as one possible complement to cross-border RMB settlement through banks and CIPS.
Concerns and debate
Critics raise concerns about privacy and state surveillance, since a centrally managed digital currency can in principle give authorities detailed visibility of payments. Others question whether the e-CNY could be used to reduce dependence on dollar-based systems or to bypass sanctions; its international use so far remains limited. Supporters point to lower costs, financial inclusion and the state's interest in keeping a public form of money as cash use declines.
