Europe’s Digital Euro Push Promises Cheaper Payments and Cash-Like Privacy

The move could cut current digital payment costs for merchants by as much as half, positioning the digital euro as a cheaper alternative to existing card networks.

At the same time, the ECB is seeking to prevent large-scale shifts of money out of commercial banks. It is considering a €3,000 individual holding limit for the digital euro, a safeguard that could still translate into as much as €700 billion flowing out of bank deposits. However, the central bank argues that such an outflow would not threaten overall financial stability.

Privacy and Offline Payments at the Core

A central pillar of the project is to replicate key features of cash in digital form. The ECB wants the digital euro to function offline, allowing transactions without an internet connection. In this mode, only the payer and the payee would know the details of the transaction. The Eurosystem would not be able to track purchases or identify users.

The offline functionality would rely on secure hardware elements embedded in smartphones or payment cards, enabling payments during power outages or in areas with weak mobile coverage. Even online, the system would rely on encryption and pseudonymization to ensure that transaction data cannot be directly linked to individuals by the central bank.

Holding Limits and the “Waterfall” Safeguard

To address concerns about bank disintermediation, the ECB has designed automatic control mechanisms.

Under the proposed €3,000 cap, individuals would not be able to hold unlimited digital euros. If a payment pushes a user above the limit, the so-called “waterfall” mechanism would automatically transfer the excess amount to the person’s linked commercial bank account.

The reverse process would also apply. If a user makes a payment larger than their digital euro balance, the system would automatically draw the remaining funds from their bank account to complete the transaction.

Businesses and public authorities would face a zero-holding limit. Any digital euros they receive would be instantly converted into commercial bank deposits, ensuring the new system does not compete with traditional deposit-taking activity.

Strategic Autonomy and Competition

The ECB argues that the digital euro is also a geopolitical project. Currently, 13 of the 20 euro area countries rely entirely on non-European payment providers such as Visa and Mastercard for digital transactions.

By creating European payment “rails,” the central bank aims to reduce dependency on foreign infrastructure. The digital euro is also framed as a public-sector alternative to private stablecoins and other crypto-assets, offering central bank backing and regulatory oversight.

Costs, Rollout Timeline, and No Interest

Under the proposed structure, the Eurosystem would cover the core infrastructure costs, estimated at around €1.3 billion for initial setup. Commercial banks would handle distribution and customer-facing services.

If EU legislation is approved in 2026, a pilot phase involving selected banks and merchants could begin in mid-2027.

Importantly, the digital euro would not pay interest. The ECB intends it to function purely as a means of payment, not as a savings vehicle, reinforcing its role as a digital equivalent of cash rather than a competing deposit product.

As legislative discussions continue, the balance between innovation, financial stability, privacy, and strategic autonomy will remain at the center of Europe’s digital currency debate.
