e-CNY 2.0: Interest Accrual, M2 Expansion, and the Dedollarisation Push

On December 31, 2025, six of China's largest state-owned banks — Industrial and Commercial Bank of China (ICBC), Bank of China, Agricultural Bank of China (ABC), China Construction Bank (CCB), Bank of Communications, and Postal Savings Bank of China (PSBC) — made a joint announcement that fundamentally changed the trajectory of the world's largest CBDC pilot. Starting January 1, 2026, balances held in e-CNY verified wallets would begin accruing interest at the listed demand deposit rate. The era of zero-interest digital yuan was over.

This seemingly technical change — a shift in how the digital yuan treats wallet balances — is in fact one of the most consequential developments in the history of central bank digital currencies. It marks the first time any central bank has paid interest on a CBDC, and it signals Beijing's intent to transform the e-CNY from a niche digital payment tool into a serious instrument of monetary policy and international financial strategy.

From M0 to M2: The 2.0 Upgrade

January 2026 was a landmark month for reasons beyond interest accrual. The People's Bank of China formally implemented the "Action Plan on Further Strengthening the Digital Renminbi Management Service System and Related Financial Infrastructure Construction" — a policy framework that had been in development for over a decade of theoretical exploration, pilot implementation, and system upgrades.

Under this framework, the e-CNY's positioning was fundamentally redefined. Originally conceived as a digital substitute for cash — strictly M0 money — the upgraded system expanded its scope to cover M1 (demand deposits, transaction money) and M2 (broad money including savings deposits and money market instruments). This represented a structural leap from what analysts now call "Cash-type 1.0" to "Deposit-currency-type 2.0."

The upgrade effectively transforms the e-CNY from a narrow payment instrument into a full-spectrum digital currency capable of functioning as a store of value, a unit of account, and a medium of exchange — the three classical functions of money — in a way its predecessor could not.

Why Interest Matters

The decision to pay interest on e-CNY wallets addresses one of the longest-standing critiques of CBDCs globally: that without interest, digital central bank money cannot compete with commercial bank deposits as a store of value. This limitation was a deliberate design choice in most CBDC projects — the ECB's Digital Euro, for instance, remains explicitly non-interest-bearing to avoid disintermediating commercial banks.

China's approach breaks this consensus. By paying interest — even at the modest rate of 0.05% — the PBoC achieves several strategic objectives:

• Incentivising holding behaviour: Users now have a reason to maintain e-CNY balances beyond transactional convenience, encouraging deeper adoption and reducing the "pass-through" effect where e-CNY is immediately converted to bank deposits.
• Enabling monetary policy transmission: An interest-bearing CBDC gives the central bank a direct channel for influencing saving and spending behaviour — a tool that non-interest-bearing digital currencies lack entirely.
• Competing with commercial deposits: While 0.05% is below most commercial savings rates, it establishes the principle that digital central bank money can function as a store of value, narrowing the gap with bank deposits over time.
• Signalling confidence: The mere fact that the PBoC is willing to pay interest signals that it views the e-CNY as a permanent, serious component of the monetary system — not a pilot or an experiment.

Expansion of Operating Institutions

In April 2026, the PBoC announced the addition of 12 new banking-type e-CNY business operating institutions, bringing the total to 22. These new institutions were connected to the PBoC's central e-CNY system, significantly broadening the distribution network for the digital yuan.

This expansion is critical for several reasons. First, it deepens the two-tier operating model — the PBoC issues, commercial institutions distribute — which has been a hallmark of the e-CNY's design. Second, it extends the reach of the e-CNY into regions and customer segments that were previously underserved by the initial cohort of operating institutions. Third, it creates a more competitive distribution environment, which should drive better user experiences and more innovative use cases.

Impact on International Payments

The strategic significance of these domestic developments becomes clearest when viewed through the lens of international payments. China has long sought to reduce its reliance on the SWIFT messaging system and the US-dollar-dominated correspondent banking network — a vulnerability highlighted sharply by the freezing of Russian central bank reserves in 2022.

The e-CNY 2.0 upgrade directly supports this agenda in several ways:

mBridge and Cross-Border CBDC Interoperability

China has been an active participant in the mBridge project — a multi-CBDC platform developed with Hong Kong, Thailand, and the UAE under the auspices of the BIS Innovation Hub. mBridge enables real-time, peer-to-peer cross-border payments using CBDCs, bypassing the correspondent banking chain entirely. With the e-CNY now functioning as interest-bearing broad money (M2), its utility in these cross-border corridors increases significantly — foreign counterparties have more reason to hold and transact in e-CNY rather than immediately converting to other currencies.

Belt and Road Settlement Networks

China has been signing bilateral e-CNY agreements with Belt and Road Initiative partners, exploring use in trade settlement and tourism. The interest-bearing feature makes the e-CNY more attractive for trade partners who might otherwise prefer to hold US dollars or euros. A Chinese exporter and a Pakistani importer can now settle in e-CNY, with the importer earning interest on the digital yuan balance held in a verified wallet — a feature no other CBDC currently offers.

Reducing SWIFT Dependency

The PBoC's own Cross-Border Interbank Payment System (CIPS) has been growing steadily, processing over 100 trillion yuan in cumulative transactions by early 2026. The e-CNY 2.0 system integrates with CIPS to create an end-to-end digital renminbi settlement pipeline that operates entirely outside the SWIFT/CHIPS infrastructure. For countries seeking to reduce their exposure to US financial sanctions — including Russia, Iran, and a growing number of Global South nations — this offers a viable alternative.

The Dedollarisation Dimension

The e-CNY 2.0 upgrade cannot be understood in isolation from the broader global trend toward dedollarisation — the process by which countries reduce their reliance on the US dollar in international trade, reserves, and financial transactions.

Several structural factors are driving this trend:

• Weaponisation of the dollar: The US has increasingly used the dollar-based financial system as a tool of foreign policy — sanctions, asset freezes, and SWIFT disconnections. This has created powerful incentives for targeted countries to develop alternative payment systems.
• BRICS expansion: The BRICS bloc (Brazil, Russia, India, China, South Africa, plus new members Iran, Egypt, Ethiopia, and the UAE) has been actively exploring alternatives to dollar-dominated trade settlement. The 2023 BRICS summit explicitly called for increased use of local currencies in cross-border trade.
• Digital currency innovation: CBDCs offer a technological path to bypassing traditional correspondent banking. The mBridge project, Project Dunbar (Australia, Malaysia, Singapore, South Africa), and various bilateral CBDC experiments are creating a parallel infrastructure for cross-border payments that does not depend on the dollar.

Challenges and Limitations

Despite these ambitious developments, the e-CNY 2.0 faces significant headwinds in its quest to reshape international payments:

• Network effects of the dollar: The dollar's dominance is sustained by deep, liquid markets, a robust legal framework, and decades of institutional trust. The e-CNY cannot replicate these overnight, regardless of its technical capabilities.
• Capital account convertibility: The renminbi is not fully convertible on the capital account. Foreign entities can hold and transact in e-CNY only within the bounds of China's capital controls, which limits its utility as a reserve asset or a truly global currency.
• Trust deficit: The e-CNY's "controlled anonymity" model — where the central bank can trace transactions — raises privacy concerns that may deter foreign adoption, particularly in jurisdictions with strong data protection norms.
• Geopolitical resistance: The US and its allies are unlikely to passively accept a shift away from the dollar system. Potential countermeasures include expanded sanctions, restrictions on Chinese financial technology, and accelerated development of alternative CBDCs (the Digital Dollar, Digital Euro) designed to compete with the e-CNY.

Comparison with Other CBDCs

The e-CNY 2.0 now stands apart from every other major CBDC project in several key dimensions:

• Interest-bearing: No other CBDC pays interest. The Digital Euro, Digital Pound, and Digital Rupee are all explicitly non-interest-bearing.
• M2 coverage: Most CBDCs are limited to M0 (cash replacement). China is the only country expanding its CBDC to cover broad money.
• Scale: With 22 operating institutions and coverage across 26 cities, the e-CNY is an order of magnitude larger than any other CBDC pilot.
• Cross-border focus: While most CBDC projects are primarily domestic in orientation, the e-CNY is explicitly designed for international use — a reflection of China's strategic ambitions.

What This Means for the Future

The e-CNY 2.0 represents a watershed moment in the history of digital currencies. By paying interest, expanding to M2, and broadening its institutional network, China has transformed its CBDC from a domestic payment experiment into a serious instrument of international financial statecraft.

The implications are profound. If the e-CNY succeeds in creating a viable alternative to the dollar-based payment system, it could fundamentally reshape the architecture of global finance — reducing the cost of cross-border payments, increasing the resilience of the international financial system, and redistributing geopolitical power away from the United States.

If it fails — if capital controls, trust deficits, or geopolitical resistance limit its adoption — it will nonetheless have forced every other central bank to reconsider the design of its own CBDC. The question of whether CBDCs should pay interest is no longer theoretical. China has answered it with a practical demonstration.

The rest of the world is now playing catch-up.
