Digital, or cryptocurrencies, were supposed to revolutionize the way we pay for goods and services. Yet in 2026, when you walk into a store or buy something online, you still reach for cash or your card.

Bitcoin's volatility and complexity have kept it from becoming everyday money. That is where the European Central Bank (ECB) steps in with plans for a stable digital currency.

For consumers, the digital euro promises a simple way to make secure payments — in shops, online or peer‑to‑peer — backed directly by Europe's central bank.

Yet the push for a digital euro isn't just a digital upgrade. It's increasingly become a geopolitical necessity.

Currency sovereignty in a shifting world

In a world where Washington can suddenly rewrite trade rules, impose tariffs overnight, or tighten AI export controls, European Union policymakers believe currency sovereignty is a critical insurance against future knee-jerk moves by the Trump administration.

Europe is heavily reliant on payment systems in the United States like Visa and Mastercard, while digital wallets and apps, including Google or Apple Pay and PayPal, add another layer of dependence.

"If globally all those transactions become dollar-denominated without a digital euro, it would limit the effectiveness of ECB monetary policy on the traditional euro," Bas van Donselaar, managing partner at the PaymentGenes Consultancy, told DW.

As more trade and payments shift online and increasingly into foreign digital currencies, the digital euro will also help the ECB better manage the money supply, respond to economic crises and protect the currency against external shocks.

Other major economies are moving faster, including China’s digital yuan, or e-CNY. Since it was first piloted in 2020, more than 230 million personal and about 18.8 million corporate e-CNY wallets have been created.

By the end of November, the Chinese digital currency had processed more than 3.48 billion cumulative retail transactions worth around 16.7 trillion yuan ($2.4 trillion, €2.1 trillion), according to Xinhua news agency.

Beijing is now pushing further, expanding cross‑border use and even allowing interest on digital yuan savings.

Protecting Europe's financial stability

For the digital euro, however, a key challenge is ensuring it does not behave like a full cash bank account. If it did, European banks could be drained of deposits — especially during a crisis such as a bank run — as consumers shift their savings into the digital euro.

"If there is no limit on how many digital euros people can hold, it becomes like a substitute for bank accounts," warned Emmanuelle Auriol, professor of economics at the Toulouse School of Economics.

To prevent this, the ECB has built in safeguards. A possible €3,000 ($3,420) cap on digital euro holdings would automatically redirect any excess back to a linked bank account.

The digital euro would also pay no interest, removing incentives to shift savings out of banks. Companies would be barred from holding large permanent balances.

Privacy without surveillance

Among consumers, privacy remains one of the biggest concerns. Some fear a central bank digital currency (CBDC) could enable state monitoring of spending, drawing comparisons to China's social credit system.

In China, citizens are scored on their behavior, including financial reliability. Low scores can restrict access to loans, jobs, public services, or travel. However, Auriol dismissed any link with the digital euro.

"Social credit systems (as in China) have nothing to do with this," she told DW. "Privacy protections can be balanced with anti-crime measures without creating social control tools."

The ECB also plans to enable peer-to-peer payments directly between phones. This would preserve cash-like anonymity for small everyday payments while still complying with anti-money laundering rules.

Evelien Witlox, director of the Digital Euro at the ECB, described the proposed currency as "a secure, public option for digital payments, combining the ease and convenience of modern payment methods with the trust and stability of cash."

Getting banks to buy into digital euro

Among the biggest challenges in rolling out the digital euro is the revenue hit European banks could take. 

Sellers currently lose a slice of every card payment to fees — often around 0.5% to 1.5% on a €100 transaction, split between the bank and payment processor. The digital euro is intended to reduce these costs.

Many retail banks argue that they will shoulder most of the cost and responsibility for building and operating the new infrastructure, while losing a significant source of fee income. As a result, many lenders are calling for higher holding limits for users and fair compensation.

"The balancing act between compensation models for banks and merchants is crucial," van Donselaar said. "While lower acceptance fees for merchants are understandable, banks will do most of the work and should have a viable business model as well."

Consumer adoption made easy

To ensure public acceptance, the ECB proposes granting the digital euro legal tender status across the eurozone. Under the current proposals, any merchant with a payment terminal would have to accept digital euros at full face value, with no extra fees for consumers.

"Like physical banknotes, its value would be backed by the Eurosystem — the European Central Bank and national central banks — so one digital euro will always equal one regular euro. Unlike cryptocurrencies, its value is stable and will not go up and down," the ECB's Witlox told DW.

Non-euro countries within the EU would also have the option of offering the currency.

The digital euro would also work offline, which could be useful during power outages or in areas with poor connectivity.

Last week, the European Parliament's Economic and Monetary Affairs Committee approved its position on the regulation, paving the way for final negotiations on the rollout of the digital euro.

EU policymakers are now aiming to adopt the legal framework later this year, with a pilot planned for 2027 and a full launch potentially in 2029.
