e-Rupee vs Digital Euro vs e-CNY: 12 Design Choices Compared (2026)

A knitwear exporter in Tiruppur sells to a buyer in Milan and buys trims from a supplier in Shenzhen. In 2026 each of those three cities sits under a different answer to the same question: what should digital cash issued by a central bank look like? India is piloting a token, Europe is legislating a capped wallet, and China has just turned its digital yuan into something closer to a bank deposit. Put side by side, the three designs say more about each country's politics than about technology.

Three projects at three different stages

The quickest way to compare them is by where they are.

• e-CNY (China) has been in testing since 2019 and is the largest by far. By the end of November 2025 it had handled 3.48 billion transactions with a cumulative value of 16.7 trillion yuan, according to BeInCrypto figures republished by Yahoo Finance.
• e-rupee (India) has been in pilot since December 2022. Retail e-rupee in circulation stood at ₹771.66 crore on 31 March 2026, down about 24% from ₹1,016.46 crore a year earlier, according to the RBI Annual Report 2025-26 as reported by Outlook Money.
• Digital euro does not exist yet. The ECB moved to its next phase in October 2025, planning for a pilot from mid-2027 and a potential first issuance in 2029, provided EU law is adopted in 2026, according to the Eurosystem announcement.

Those three snapshots also map onto three motives. China wants a state-run alternative to two dominant private wallets; India wants a programmable public rail alongside an already dominant public rail, UPI; Europe wants a European option in a card market run mostly by non-European networks. For background on each, see the digital rupee explained, the digital euro explained and China's e-CNY.

The full comparison table

Design: token, account, or deposit

The RBI's 2022 concept note chose a token for retail use, distributed through banks, with fixed denominations similar to notes. The aim was to make the e-rupee feel like cash and to build trust. It also lets the e-rupee move wallet to wallet without touching a bank account, which UPI cannot do.

The digital euro is a hybrid. Online it behaves like an account held at an intermediary, settled by the Eurosystem. Offline it behaves like a bearer instrument on a secure chip. It remains a direct claim on the central bank either way.

China's change is the most dramatic. From 1 January 2026, the PBoC reclassified the e-CNY from digital cash to "digital deposit money", a liability of commercial banks, covered by deposit insurance and subject to reserve requirements, according to the same Yahoo Finance report and a China Daily analysis republished by Capital FM. Non-bank payment institutions issue e-CNY against customers' bank deposits under full reserve rules. In practice, China has moved its CBDC from M0 toward M1. That is a significant philosophical retreat from the "digital cash" idea, and an admission that cash-like money paying nothing struggled to compete.

Holding limits and interest: the bank-protection question

Every central bank fears that a safe, free digital currency would drain bank deposits. Each answers differently.

Europe uses a hard cap and zero interest. ECB staff analysis, prepared for legislators and reported by MNI in October 2025, examined limits of up to €3,000 and found that in a severe stress case where everyone held the maximum, withdrawals could reach €699 billion, about 8.2% of retail sight deposits. Parliament's committee text, approved on 23 June 2026, generally bars businesses from holding large balances, though they may keep funds for up to 24 hours to accumulate incoming payments, and makes basic services free, according to Crowdfund Insider.

India uses zero interest and has so far relied on the pilot's small scale rather than a published cap. With under ₹800 crore in circulation, deposit flight is not a live risk.

China has gone the opposite way: by making the e-CNY a bank liability that can pay interest, it removes the disintermediation question entirely, because e-CNY balances are bank deposits. The cost is that the e-CNY is no longer meaningfully different from a bank account for its holder.

China solved the deposit-flight problem by making its CBDC a deposit. Europe is trying to solve it with a cap. India has not yet had to solve it at all.

Worked example: three numbers that tell the story

Raw totals are hard to compare because the three projects report different things. Simple ratios help.

• e-rupee per user. ₹771.66 crore in circulation in March 2026, divided by roughly 7 million users reported in late 2025, works out to about ₹1,100 per user. That is a wallet balance, not a savings product.
• e-CNY per transaction. 16.7 trillion yuan across 3.48 billion transactions is an average of about 4,800 yuan per transaction. Large business and government payments clearly pull that average well above a typical shop purchase.
• Digital euro stress case. If €699 billion equals 8.2% of retail sight deposits, the implied pool of such deposits is about €8.5 trillion. And €699 billion at €3,000 per head implies roughly 233 million people holding the maximum. The ECB's own worst case assumes most of the euro area's adults fill their wallets on day one, which is why it concludes the risk is manageable.

Now take a saver with the equivalent of ₹50,000 in each. In e-rupee or digital euro it would earn nothing, and in the euro case anything above the cap would sit in a bank account instead. In e-CNY, from 2026, it would earn whatever the holding bank chooses to pay, since the PBoC has not set a rate. Only the Chinese design treats CBDC as a place to keep money; the other two treat it as a way to spend it.

Per-user and per-transaction figures are our calculations from published totals and mix dates a few months apart; they are approximations.

Offline and privacy

All three support some form of offline use. China tested phone-to-phone "dual offline" payments in Suzhou in December 2020 and has hardware card and SIM wallets. The ECB's progress report describes device-to-device offline payments where only the two parties know personal details. The RBI has piloted offline e-rupee since 2024 for low-connectivity areas. We explain the mechanics in offline CBDC payments.

On privacy, Europe has made the most explicit commitments, with offline cash-like privacy and pseudonymised online data at the ECB. India's concept note promises managed anonymity, with small payments more private than large. China's shift to deposit money brings e-CNY balances under bank account rules. For the arguments, read the CBDC privacy debate.

Adoption: why bigger is not the same as wanted

China's numbers dwarf the others, but even there adoption has been described as poor relative to the effort spent, which is part of why the PBoC changed the model, as Trivium China noted. A 2021 China Daily report put Alipay and WeChat Pay together at more than 90% of the country's mobile payments market, and nothing in the e-CNY's design gave everyday users a strong reason to switch.

India faces a similar problem with a public competitor rather than private ones. UPI handles several hundred million payments a day, and the e-rupee's falling circulation suggests few people choose to hold it without a scheme pushing it to them. Its most distinctive use, programmable welfare money, is designed to be spent quickly.

Europe has the opposite problem: political support but no product yet. The European Parliament voted 416 to 169, with 22 abstentions, on 9 July 2026 to open negotiations with the Council, according to Eunews, with the first trilogue on 13 July.

Cost and timeline

Only the ECB has published a full cost estimate. Development to first issuance is estimated at about €1.3 billion, of which about €265 million is external, with operating costs of about €320 million a year from 2029, to be covered by seigniorage. Neither the RBI nor the PBoC has published comparable figures. For the global picture, see our CBDC tracker, which counts 146 countries exploring a CBDC.

What to watch next

• Second half of 2026: EU trilogue negotiations on the digital euro regulation, aiming for agreement by year end, including how the holding cap is set.
• 2026 in China: the first full year of interest-bearing e-CNY; watch the rates banks choose to pay and whether transaction growth picks up.
• 2026-27 in India: RBI plans to extend e-rupee pilots to more DBT schemes and explore cross-border pilots with select partners.
• Mid-2027: the earliest date for a digital euro pilot and initial transactions, under the ECB's plan.
• 2029: the ECB's target for a potential first issuance.
