The Digital Euro And The European Payment Garden

On 9 July 2026, the European Parliament approved the opening of negotiations on the digital euro by 416 votes to 169, with 22 abstentions.

Five days later, the European Central Bank announced that it had selected 36 payment service providers to participate in a 12-month pilot beginning in the second half of 2027. The test will involve the ECB, 19 national central banks, merchants and central-bank employees making online, offline, person-to-person and commercial payments with a beta version of the system.

Provided the legislation is adopted, the ECB aims to be technically ready for a possible first issuance during 2029.

This is excellent news, because physical cash has remained dangerously primitive.

A banknote can be held without permission, transferred freely, saved without a balance ceiling and spent without first establishing whether its owner remains in good administrative standing. It cannot receive emergency updates, communicate with a digital identity wallet or automatically move itself into another account.

Cash, in other words, has spent centuries operating without adequate supervision.

The digital euro will finally correct this.

The ECB’s main arguments are

Online Payments: A Solution to a Problem That Consumers Do Not Have

According to the ECB’s own 2024 payment study, online purchases represented 21 percent of day-to-day transactions by number and 36 percent by value.

Europeans already pay online through debit cards, credit cards, bank transfers, instant payments, direct debits, mobile wallets, prepaid services and numerous national payment systems.

By the first half of 2025, the euro area had an average of 2.5 payment cards for every inhabitant.

The EU has also already required euro-area payment providers to support sending and receiving instant transfers, while European initiatives such as Wero are developing account-to-account payments for online, in-store and person-to-person transactions.

The digital euro does not solve an inability to pay. It changes the nature of the money. A bank deposit is a claim on a commercial bank. A digital euro would be a direct claim on the central bank. This distinction matters to the ECB, but it gives ordinary users no meaningful new capability for everyday use.

Strategic Autonomy: A Real Problem, Wrong Solution

Europe’s dependence on foreign payment networks is real. International schemes (mainly Visa and Mastercard) dominate card payments. However, this is dependence on infrastructure and companies, not on a foreign currency. Europeans already pay in euros.

Europe could reduce this dependency by expanding European card schemes, instant account-to-account payments, common technical standards, SEPA infrastructure, TIPS and private European systems such as Wero.

The digital euro packages two separate questions together.

The first is whether Europe should control more of its payment infrastructure. The answer is reasonably yes.

The second is whether citizens therefore need personal central bank wallets containing a specially designed digital currency with holding limits, intermediaries, new settlement systems and an entire additional regulatory structure.

European banking representatives have warned that the planned system could duplicate existing instant-payment infrastructure and create parallel settlement, certification, fraud-monitoring and dispute-handling systems where equivalent European systems already operate.

That institutional preference is understandable. Institutions have rarely encountered a public problem that could not be improved by enlarging the institution.

Privacy: Better Than PayPal, Not Comparable to Cash

The ECB claims the digital euro will offer “the highest degree of privacy currently possible.” This claim is misleading.

For online payments, users will still go through banks or payment service providers. These intermediaries will verify identity, manage wallets, and comply with anti-money laundering rules. All online transactions are expected to be recorded. The European Data Protection Board has already warned that enforcing holding limits will require personal data processing and prevent true anonymity.

Offline payments offer better privacy, but even then the system requires wallets to be funded through the regulated financial system. The result may be better privacy than commercial platforms that aggressively track user behaviour, but it is nowhere near the anonymity of physical cash.

Unlike cash, a digital system can also receive updates. Privacy protections today can be changed by legislation or software updates tomorrow. Cash cannot receive a policy update. A digital payment system can.

Costs: Free for Users, Expensive for Everyone Else

Basic services are supposed to be free for consumers. This does not mean the system is free overall.

The ECB estimates €1.3 billion in development costs and around €320 million in annual operating costs.

Banks are expected to spend another €4–6 billion on implementation. They will fund their implementation expenses from their own budgets, which are financed through their customers, shareholders, service charges and lending margins.

Merchants would not receive the service for free either. Payment providers would be permitted to charge them for processing digital euro transactions. The Commission’s proposal says merchant charges should not exceed those for comparable payment methods such as debit cards or instant payments.

They would also face integration, software, hardware, accounting, compliance and staff-training costs.

These costs will ultimately be passed on through higher prices, banking fees, or reduced returns to national budgets.

The banking system implications - Risks and Complications for Monetary Policy

Beyond the direct costs of adaptation, the digital euro introduces structural pressure on banks’ balance sheets through deposit disintermediation. Although the ECB has proposed safeguards such as non-remunerated holdings, individual holding limits (widely discussed around €3,000), and a reverse waterfall mechanism to automatically shift excess balances back into commercial bank accounts, independent stress tests indicate that significant outflows remain possible. 

In adverse scenarios, up to €700 billion in retail deposits - roughly 8% of euro area sight deposits - could migrate into digital euros, forcing banks to replace relatively cheap and stable retail funding with more expensive wholesale sources. 

Serious analysis highlights significant risks to the effectiveness and stability of monetary policy:

A. Weakening of the Bank Lending Channel

The most important transmission mechanism in the euro area is the bank lending channel.

If a large share of deposits moves into a digital euro (which is a direct liability of the central bank), banks lose cheap retail deposits. They must then replace this funding with more expensive wholesale borrowing. This raises their overall cost of funds, which can lead to:

• Higher lending rates for borrowers, or
• Reduced willingness to lend.
• This effect is stronger for smaller banks, which rely more heavily on retail deposits and have less access to alternative funding markets.

B. Faster and Larger Bank Runs (“Fast Disintermediation”)

Physical cash has natural limits (you can only withdraw and store so much). A CBDC removes this friction. In a crisis of confidence, people could move money from bank deposits into digital euros almost instantly and at very large scale. This could accelerate bank runs and make them more severe than in the past.

C. Changes to the Operational Framework

Large-scale CBDC adoption would shrink bank deposits and, consequently, bank reserves at the central bank. This could shift the monetary policy operational framework from the current floor system (with abundant reserves) toward a corridor or even ceiling system. In such a system, banks would need to borrow more frequently from the central bank, increasing the central bank’s footprint in the financial system and complicating liquidity management.

D. Reduced Effectiveness of Conventional Tools

If banks become more dependent on central bank funding due to lost deposits, the central bank may have to lend more aggressively to maintain the desired monetary policy stance.

Officials repeatedly stress that the digital euro is not meant to replace physical cash.

The digital euro can therefore be defended as a geopolitical infrastructure project, but NOT an urgently requested consumer service that solves Europeans’ inability to pay online, gives them cash-level privacy and somehow costs nobody anything.

Future implications

The digital euro is a new layer of monetary infrastructure with capabilities that physical cash and existing bank deposits do not possess.

Infrastructure for Control

By placing a centralized digital currency under the direct control of the central bank and its intermediaries, the digital euro introduces technical possibilities that did not exist with physical cash:

• The ability to impose holding limits on individuals.
• The technical foundation for programmable money, even if current proposals explicitly rule it out.
• Much easier mechanisms for monitoring, restricting, or freezing payments at scale.
• A single point of control that future governments could expand during crises or for policy objectives.

These features do not need to be activated immediately. Once the infrastructure exists, expanding its use becomes a matter of legislation and software updates rather than building new systems from scratch.

Potential for Direct Monetary Interventions

A digital euro creates the technical preconditions for forms of monetary policy that are currently difficult or impossible to implement at scale:

• Helicopter money: The term comes from economist Milton Friedman (1969), who used the metaphor of a helicopter dropping cash from the sky so that people would have more money to spend. The idea is to stimulate the economy directly by boosting consumption when conventional tools (like interest rate cuts) are no longer effective. The central bank could, in principle, distribute newly created money directly to citizens’ wallets. While current plans do not include this, the infrastructure would make such operations far easier to execute than with existing systems.
• Targeted or conditional stimulus: Money could be distributed with restrictions on how, where, or when it can be spent.
• Programmable features: Although not part of the current proposal, the system’s architecture would allow future governments to introduce conditions on money (expiry dates, spending categories, or geographic restrictions) through software updates.

Geopolitical Isolation and the European Payment Garden

One of the more consequential long-term risks is the digital euro’s potential use as a tool to reduce Europe’s dependence on foreign payment systems - this goal carries the risk of gradually isolating Europeans from global digital services.

In a worst-case development, this could evolve through:

• Regulatory and technical friction that makes foreign payment methods more expensive or less convenient inside Europe.
• “European preference” policies that push public services and eventually private platforms to prioritize the digital euro.
• Restrictions on outflows to foreign payment systems during periods of geopolitical or economic tension.

Dystopian trajectory (2035–2045)

If these tendencies intensify, Europe could develop a relatively closed payment ecosystem.

International platforms would face higher costs or technical barriers when dealing with European users.

Freelancers, content creators, and businesses would find it increasingly difficult and expensive to receive payments from outside Europe.

Access to global services - from cloud computing and specialized software to international education platforms and crowdfunding - would become progressively more complicated.

Europeans would not lose access to the internet.

They would, however, face growing friction when trying to participate economically in the global digital economy. Over time, this could produce a closed, inward-looking European digital space - justified at each step by the language of sovereignty and resilience, but functioning in practice as a partial digital enclosure.

The digital euro is not primarily a response to consumer demand. Europeans can already pay online, in stores, and to each other efficiently.

The digital euro is not a neutral upgrade. It is the foundation of a new monetary architecture that gives European institutions far greater control over money than they have ever possessed in peacetime. Once this system is in place, the direction of travel becomes difficult to reverse.

In ten to twenty years, the likely outcome is not a dramatic overnight seizure of power, but a slow, bureaucratic enclosure. The digital euro, combined with digital identity systems and regulatory pressure, could gradually make it more difficult and expensive for Europeans to interact with the outside world through foreign payment networks.

What begins as “strategic autonomy” could evolve into a de facto payment firewall. International platforms, foreign services, and cross-border transactions would face increasing friction. Freelancers, businesses, researchers, and ordinary citizens who rely on global services would be forced to navigate an ever-narrowing set of approved European channels.

This development would not happen in isolation. The EU has already shown a clear willingness to regulate and restrict access to information and foreign platforms through laws such as the Digital Services Act and Digital Markets Act.

Over time, this creates something uncomfortably close to a modern version of the Eastern Bloc economy. Just as citizens of the Soviet bloc lived inside a closed economic system where access to foreign goods, currencies, and information was tightly controlled by the state, Europeans could find themselves inside a digitally managed space where both money and information are increasingly filtered through European institutions.

In such a system, the ability to participate in the global digital economy would no longer be a basic feature of modern life. It would become a privilege. The internet would still exist. But the ability to move money across it freely would be significantly constrained.

This is not an inevitable outcome. It is, however, a logical one if the digital euro is allowed to become the dominant payment rail while Europe continues to prioritise control over openness. The project does not need to be turned into an instrument of repression to produce these effects. It only needs to continue along its current path of expanding institutional power, reducing alternatives, and treating global interoperability as a secondary concern.
