1. Introduction

The dawn of the 21st century has witnessed an unprecedented acceleration in digital innovation, precipitating a profound and pervasive transformation across nearly every sector of the global economy, with the financial realm standing at the vanguard of this paradigm shift. The proliferation of digital technologies has ushered in a new era characterized by the emergence of novel monetary forms and payment solutions that challenge traditional paradigms. Foremost among these are decentralized cryptocurrencies like Bitcoin and Ethereum, which operate independently of central authorities, and stablecoins, which aim to peg their value to existing fiat currencies. Alongside these, a myriad of sophisticated private digital payment solutions, often leveraging advanced technological infrastructures, have rapidly gained traction, altering consumer payment habits and presenting both opportunities and challenges for established financial systems (Financial Times, 2025).

This landscape of rapid digitalization has prompted central banks worldwide to critically reassess their roles in maintaining monetary sovereignty, financial stability, and public trust in an increasingly digital economy. The fundamental question confronting monetary authorities is how to ensure that official, central bank-backed money remains the anchor of the financial system amidst the proliferation of private digital assets and payment instruments. The concern is that if private digital monies, particularly those issued by large technology firms or foreign entities, become dominant, they could undermine monetary policy transmission, introduce new forms of systemic risk, and potentially erode the sovereign’s control over its currency (European Central Bank, 2022).

In response to these epochal shifts, the European Central Bank (ECB), representing the collective interests of the eurozone, has embarked on a strategic and ambitious initiative: the development of a digital euro. This endeavor is not merely a technological upgrade but a comprehensive strategic project aimed at modernizing the eurozone’s payment infrastructure, safeguarding its monetary sovereignty, and reinforcing the euro’s international standing in an increasingly digitalized global financial order. The digital euro is envisioned not as a replacement for cash or existing commercial bank money, but as a complementary form of central bank money accessible to the public, designed to future-proof the euro’s role as a trusted and efficient medium of exchange.

2. The Rationale for the Digital Euro

The decision to pursue a digital euro is underpinned by a compelling array of strategic imperatives, each addressing distinct facets of the evolving financial landscape and aiming to secure the euro area’s economic and monetary future.

2.1 Financial Stability

Financial stability forms the bedrock of any robust economy, and the digital euro is designed to act as a crucial bulwark against emerging threats to this stability. As societal payment habits continue to shift inexorably away from physical cash, driven by the pervasive adoption of e-commerce and digital payment solutions, the traditional role of central bank money as a universally accessible and risk-free public good faces erosion. Statistics from various European countries confirm a steady decline in cash usage for retail payments, a trend exacerbated by events like the COVID-19 pandemic which accelerated digital adoption (ECB, 2022 Annual Report). This decline raises concerns about the long-term viability of cash as a fully available payment option and the implications for financial systems relying heavily on private sector innovation.

The proliferation of private digital payment solutions, while offering convenience, introduces new layers of complexity and potential fragility. Many of these solutions are operated by large, often non-European, technology companies, raising questions about data governance, operational resilience, and the potential for market dominance. More critically, the rise of stablecoins and other private digital assets, if widely adopted, could pose significant systemic risks. Unlike central bank money, stablecoins, even those purportedly backed by fiat currencies, are susceptible to ‘runs’ if confidence in their reserves or operational integrity wavers. A sudden loss of confidence in a widely used stablecoin could trigger contagion across the financial system, potentially impacting traditional banks and disrupting payment flows (Financial Times, 2025). The ECB aims to pre-emptively mitigate such risks by providing a public, risk-free digital alternative, thereby ensuring that the euro remains a stable and trusted medium of exchange, irrespective of the form it takes.

Furthermore, the digital euro could serve as a ‘safe anchor’ during times of financial stress. In scenarios where public confidence in commercial banks or specific private payment providers might falter, individuals and businesses could theoretically shift funds into the digital euro, which, as a liability of the central bank, carries no credit risk. This ‘flight to safety’ mechanism would provide an essential stabilizing force, preventing broader systemic crises and ensuring continued access to money for essential transactions. By providing a direct claim on the central bank, the digital euro enhances the resilience of the overall payment ecosystem, complementing the existing two-tiered banking system and maintaining the public’s confidence in the stability of the currency itself (Deutsche Bundesbank, 2022).

2.2 Strategic Autonomy

The digital euro is a cornerstone of the eurozone’s broader ambition to enhance its strategic autonomy in an increasingly fragmented and competitive global financial landscape. The current global payment architecture largely relies on a handful of dominant foreign payment networks (e.g., Visa, Mastercard) and messaging systems (e.g., SWIFT), which, while efficient, inherently create dependencies. These dependencies can pose significant vulnerabilities, particularly in geopolitical contexts where financial sanctions or economic leverage are employed. By developing a sovereign European CBDC, the ECB aims to reduce this reliance on non-European infrastructures, thereby safeguarding the eurozone’s ability to act independently and exercise control over its own monetary and financial affairs (European Council, 2023).

Strengthening the euro’s international role is another critical facet of strategic autonomy. In a world where several major economies, notably China with its Digital Yuan (e-CNY), are aggressively pursuing their own CBDCs, the eurozone risks being left behind if it does not offer a competitive digital form of its currency. A robust digital euro could bolster the currency’s appeal for cross-border transactions, trade invoicing, and foreign reserves, ultimately reinforcing its status as a global reserve currency. It would offer a European alternative to potentially dominant foreign digital currencies or stablecoins, ensuring that European values, regulatory standards, and data protection principles are embedded within a key digital payment instrument (European Commission, 2023).

Furthermore, the digital euro could provide a secure and efficient conduit for international payments, reducing friction and costs associated with cross-border transactions. This could support European businesses in global trade and investment, further integrating the euro area into the global economy while maintaining sovereignty over its financial infrastructure. It ensures that critical financial data generated within the Euro area remains under European jurisdiction, enhancing data sovereignty and mitigating risks associated with foreign access to sensitive transactional information.

2.3 Payment Efficiency

The introduction of the digital euro is expected to herald a new era of payment efficiency, marked by faster, more secure, and more cost-effective transactions across the Euro area. The existing payment landscape, while advanced in many respects, still suffers from inefficiencies, particularly concerning cross-border payments within the single market and beyond. These often involve multiple intermediaries, complex reconciliation processes, and relatively high fees, especially for small and medium-sized enterprises (SMEs) and individuals. The digital euro, as a unified digital public infrastructure, could significantly streamline these processes.

Key to this efficiency is the potential for instant settlement. Unlike traditional interbank transfers that may take hours or even days to settle, especially across borders, a digital euro could enable near-instantaneous transfers 24/7, irrespective of weekends or public holidays. This would liberate capital, improve liquidity management for businesses, and accelerate economic activity. The direct nature of central bank money transactions, or intermediated transactions with direct central bank backing, could dramatically reduce the number of intermediaries involved, thereby lowering transaction costs for both consumers and businesses. This is particularly beneficial for low-value payments, fostering broader digital adoption for everyday transactions (European Central Bank, 2023).

The digital euro is also envisioned as a catalyst for innovation within the financial sector. By providing a foundational, universally accessible digital currency, it creates a robust platform upon which new payment services and business models can be built. FinTech companies, payment service providers, and traditional banks could leverage the digital euro’s core capabilities to develop advanced applications, such as integrated payment solutions for the Internet of Things (IoT), sophisticated smart contracts for automated supply chain finance, or innovative retail payment experiences. The aim is to foster a more competitive and dynamic payment ecosystem that can respond agilely to evolving consumer and business needs, promoting greater integration and efficiency across the eurozone economy.

2.4 Financial Inclusion

Promoting financial inclusion is a deeply embedded objective of the digital euro project, aiming to ensure that all citizens within the euro area, regardless of their socio-economic status or access to traditional banking services, can fully participate in the increasingly digitalized economy. While the euro area generally enjoys high levels of financial access, pockets of ‘unbanked’ or ‘underbanked’ individuals persist, including certain elderly populations, low-income households, migrants, or those residing in remote areas where physical banking infrastructure may be limited.

For these groups, a digital euro could offer a secure, accessible, and user-friendly means of payment that complements, rather than replaces, physical cash. It would provide a public option for digital payments that does not require a commercial bank account, potentially using dedicated digital wallets or simple applications accessible via mobile devices. This ensures that individuals who may not meet the eligibility criteria for traditional bank accounts, or who prefer not to use commercial banking services, are not excluded from the growing digital sphere of economic activity. This is particularly relevant as many public services, benefits, and commercial transactions increasingly transition to digital-only platforms.

Moreover, in times of crisis or disruption to commercial payment systems, the digital euro could serve as a resilient alternative, ensuring that essential payments can still be made. Its availability as central bank money would provide a fundamental layer of resilience, safeguarding citizens’ access to money for basic necessities. By offering a digital payment option that is universally accepted and free from the commercial complexities and potential fees associated with private payment solutions, the digital euro aims to lower barriers to entry for digital participation, fostering a more equitable and inclusive digital society across the eurozone (HuffPost España, 2025).

3. Collaborative Efforts and Use Cases

The development of the digital euro is not a unilateral undertaking by the ECB but a deeply collaborative process, engaging a broad spectrum of stakeholders to ensure its design is robust, user-centric, and aligned with market needs. This collaborative approach extends to the exploration and development of innovative use cases that leverage the unique attributes of a CBDC.

3.1 Collaboration with Market Participants

The ECB has structured the digital euro project as a two-tiered system, where the Eurosystem would issue the digital euro, but commercial banks and other supervised payment service providers (PSPs) would be responsible for its distribution and interaction with end-users. This model necessitates extensive collaboration with a wide array of stakeholders, including:

  • Commercial Banks: Essential for distribution, customer onboarding (KYC/AML), and integration with existing banking infrastructure. They bring crucial expertise in retail payments and customer service.
  • Payment Service Providers (PSPs) and FinTech Companies: These entities are vital for developing innovative front-end solutions, expanding acceptance networks, and creating new services built upon the digital euro’s core capabilities.
  • Technology Providers: Specialists in cybersecurity, blockchain/DLT, user interface design, and secure hardware are indispensable for building the underlying technical infrastructure.
  • Consumer Associations: Their input ensures that user needs, privacy concerns, and accessibility are adequately addressed.
  • Retailers and Merchants: Their perspectives are crucial for ensuring the digital euro is practical for point-of-sale transactions and integrated into their business processes.
  • Regulatory Bodies and National Authorities: Collaboration ensures legal and regulatory compliance, addressing issues like anti-money laundering (AML), combating the financing of terrorism (CFT), and data protection.

This broad engagement has involved a comprehensive investigation phase (concluded in October 2023) and is currently in a preparation phase. During these phases, the ECB has conducted public consultations, technical workshops, and regular dialogues with industry groups, seeking feedback on design choices, functionalities, and potential impacts (European Central Bank, 2023). The goal is to leverage the expertise of the private sector, foster competition, and ensure that the digital euro seamlessly integrates into and enhances the existing payment ecosystem, rather than disrupting it unnecessarily. The ECB aims to finalize the selection of technology providers for the digital euro by mid-2025 (cincodias.elpais.com, 2025).

3.2 Programmable Payments

One of the most transformative potential features under consideration for the digital euro is programmable payments. This functionality goes beyond simple value transfer, enabling payments to be executed automatically when predefined conditions are met. While not all transactions would require or benefit from programmability, its inclusion could unlock significant efficiencies and innovation across various sectors.

Examples of potential applications include:

  • Supply Chain Management: Payments could be automatically released upon confirmed delivery of goods, verification of quality checks, or completion of specific contractual milestones. This reduces administrative overhead, minimizes disputes, and accelerates cash flow for businesses.
  • Machine-to-Machine Payments: In the context of the Internet of Things (IoT), smart devices could automatically pay for services or resources. For instance, an autonomous vehicle could pay for charging at a station, or a smart appliance could pay for electricity consumption directly.
  • Conditional Public Services and Grants: Governments could disburse subsidies or welfare payments that are automatically restricted to specific uses (e.g., educational materials, medical expenses) or activated only when certain eligibility criteria are continuously met. This enhances accountability and ensures funds are used as intended.
  • Escrow-like Functionalities: In real estate transactions or large-scale project financing, funds could be held and released automatically once all parties fulfill their obligations, reducing the need for costly intermediaries.
  • Micro-payments and Subscription Models: Programmable features could facilitate highly efficient micro-payments for digital content, streaming services, or usage-based utilities, enabling new business models and enhancing user experience.

It is crucial to note that while the digital euro could technically support such advanced features, the ECB has emphasized that programmability would primarily be implemented at the level of the intermediaries (commercial banks, PSPs) and would always be initiated and controlled by the user, adhering to strict privacy and user autonomy principles. The central bank itself would not program the digital euro to enforce specific behaviors, but rather provide the technical rails for market participants to innovate responsibly (European Central Bank, 2022).

3.3 Offline Capabilities

The ability to conduct digital euro transactions without an internet connection is a crucial feature under active investigation, addressing concerns about resilience, accessibility, and financial inclusion. Offline functionality ensures that the digital euro remains usable even in situations of network outage, power failure, or in remote areas with limited or no connectivity, mirroring the resilience of cash.

Technical approaches for offline payments often involve secure hardware elements (e.g., on a smartphone or a dedicated card) that can store and transfer digital value directly between devices, validated cryptographically. Recent academic research explores methods like Groth-Sahai proofs and secure multi-party computation to enable private and secure offline transactions while preventing double-spending and counterfeiting (arXiv, 2024, arXiv, 2024).

Practical implications include:

  • Disaster Resilience: In the event of natural disasters or widespread power outages that cripple communication networks, offline digital euro could ensure continued access to essential payment services, allowing humanitarian aid, emergency supplies, and basic commerce to proceed.
  • Rural and Underserved Regions: For populations in remote areas with unreliable internet access, offline capabilities would guarantee equal participation in the digital economy, avoiding digital exclusion.
  • Everyday Small Transactions: Similar to cash, offline digital euro could be ideal for small-value transactions in settings like public transport, local markets, or small shops where connectivity might be sporadic or slow.
  • Enhanced Privacy: Transactions conducted offline may offer a higher degree of privacy, as they might not immediately register on a central ledger, akin to physical cash transactions. However, mechanisms to prevent illicit activities like money laundering would still need to be embedded, likely through limits on offline transaction values and cumulative balances, and periodic online synchronization.

The development of robust offline capabilities presents significant technical challenges, particularly in ensuring security against fraud (e.g., double-spending) and maintaining integrity, but the ECB views it as essential for the digital euro’s universality and public acceptance.

4. Global Context of CBDCs

The European Central Bank’s pursuit of a digital euro is not an isolated phenomenon but rather a response to a global trend, as central banks worldwide grapple with the implications of digitalization for monetary policy, financial stability, and national sovereignty. The global CBDC landscape is characterized by diverse motivations, technological approaches, and stages of development, offering valuable insights and lessons for the euro area.

4.1 Global Developments in CBDCs

Central banks globally are actively researching, piloting, and, in some cases, implementing CBDCs, driven by a confluence of factors including declining cash usage, the rise of private digital assets, the need for more efficient payment systems, and geopolitical considerations. These initiatives broadly fall into two categories: retail CBDCs (for general public use) and wholesale CBDCs (for interbank use or financial institutions).

  • China’s Digital Yuan (e-CNY): As one of the most advanced retail CBDC projects, China’s e-CNY is already in extensive pilot programs across numerous cities. Motivations include modernizing its payment system, enhancing financial inclusion, maintaining monetary control, and potentially reducing reliance on foreign payment networks. While China emphasizes convenience and efficiency, concerns regarding potential state surveillance and control over financial transactions have been raised, given the e-CNY’s programmability features and the government’s access to transactional data. Its rapid rollout and widespread adoption efforts highlight a distinct approach to digital currency implementation (People’s Bank of China, various publications).

  • Sweden’s e-krona: Sweden, one of the world’s least cash-dependent societies, has been a frontrunner in exploring a retail CBDC, the e-krona. The Riksbank’s primary motivations stem from the dramatic decline in cash usage, aiming to ensure that the public retains access to central bank money and to maintain the resilience of the payment system. Their pilot projects have explored different technical solutions, including DLT-based and non-DLT solutions, focusing on user-friendliness, security, and scalability. Sweden’s approach emphasizes democratic values and consumer privacy, contrasting sharply with China’s more centralized model (Sveriges Riksbank, various reports).

  • Bahamas’ Sand Dollar: The Sand Dollar, launched in 2020, stands as the world’s first fully implemented retail CBDC. Its unique context, an archipelago nation with dispersed populations, makes financial inclusion a primary driver. The Sand Dollar aims to reduce the cost and improve the efficiency of payments across islands, including for those without traditional bank accounts. It highlights how CBDCs can address specific geographical and socio-economic challenges, providing a model for smaller economies (Central Bank of The Bahamas, various publications).

  • Other Notable Projects:

    • United States (Project Cedar, etc.): The Federal Reserve has been actively researching a digital dollar, focusing on a robust, privacy-preserving, and widely accessible design. The emphasis is on whether a CBDC could complement rather than disrupt the existing financial system, with no immediate plans for issuance.
    • United Kingdom (Digital Sterling): The Bank of England and HM Treasury have launched a consultation on a potential digital sterling, highlighting its potential to maintain the UK’s position as a financial hub and to provide a trusted means of payment in a digital age.
    • Project Jura (Switzerland & France): A wholesale CBDC project focusing on cross-border settlement using distributed ledger technology, demonstrating potential for increased efficiency and reduced risk in interbank and cross-border payments.
    • Project Ubin (Singapore): A multi-phase project exploring the use of DLT for clearing and settlement of payments and securities, showcasing the potential for wholesale CBDCs to transform financial market infrastructures.

The global landscape reveals a common recognition of the strategic importance of CBDCs, but also a divergence in design choices regarding privacy, intermediation models, interest-bearing status, and limits on holdings, all tailored to specific national contexts and policy objectives.

4.2 Economic and Social Implications

The introduction of CBDCs carries profound economic and social implications, necessitating careful consideration during their design and implementation.

Economic Implications:

  • Monetary Policy Transmission: CBDCs could potentially offer new tools for monetary policy. For instance, an interest-bearing CBDC could allow central banks to directly influence interest rates for retail holders, potentially enhancing the precision and speed of monetary policy transmission. In periods of extreme economic stress, negative interest rates on CBDCs could be implemented more directly to stimulate spending, though this remains a contentious and hypothetical application.
  • Financial Intermediation and Bank Funding: A significant concern is the potential for disintermediation, where a widely adopted CBDC could lead to a ‘flight from deposits’ from commercial banks to the central bank, especially during times of crisis. This could reduce banks’ stable funding sources and impair their ability to lend. To mitigate this, many central banks, including the ECB, propose limiting individual CBDC holdings (e.g., ‘value caps’) and implementing a tiered system where commercial banks continue to play the primary role in customer relationships, preventing a mass shift of deposits. The digital euro is conceived as a complement to bank deposits, not a replacement (Eurogroup, 2023).
  • Payment System Efficiency and Innovation: As discussed, CBDCs promise to lower transaction costs, enable instant payments, and foster innovation by providing a new public payment rail. This could enhance competition in the payment sector, potentially reducing fees for consumers and businesses currently charged by private payment providers.
  • Seigniorage: While a secondary concern, a CBDC could impact central bank seigniorage (profit from issuing currency), though the extent would depend on its design and adoption rate.

Social Implications:

  • Financial Inclusion: As highlighted, CBDCs can bridge gaps for the unbanked and underbanked, ensuring access to digital payments for all citizens, promoting economic participation and reducing reliance on costly alternative financial services.
  • Privacy vs. Surveillance: This is perhaps the most contentious social aspect. The inherent traceability of digital transactions, if not carefully managed, could lead to concerns about government surveillance and loss of individual financial freedom. Balancing privacy with the imperative to combat illicit financial activities (AML/CFT) is a delicate act that heavily influences public acceptance.
  • Digital Divide: While promoting inclusion, the introduction of a digital-only currency could also exacerbate the ‘digital divide’ if not accompanied by robust educational initiatives and accessible interfaces for elderly or digitally illiterate populations. Ensuring offline functionality and user-friendly designs are critical for widespread adoption across all demographics.
  • Government Control: Beyond surveillance, fears exist that a CBDC could give governments unprecedented control over individuals’ finances, potentially allowing for direct taxation, expiry dates on money (programmability without consent), or even direct withdrawal. Central banks consistently deny these intentions, emphasizing user control and privacy-by-design principles, but public trust and transparent legal frameworks are essential to counter such concerns.

4.3 Privacy and Data Concerns

Privacy stands as a paramount concern in the design and eventual adoption of the digital euro. The inherent digital nature of a CBDC means that, unlike physical cash, transactions leave a digital footprint. Striking the optimal balance between ensuring user privacy and meeting the legitimate requirements for regulatory oversight (e.g., preventing money laundering, terrorist financing, and serious crime) is one of the most significant design challenges. Full anonymity, akin to physical cash, is generally deemed unfeasible and undesirable for large transactions due to these regulatory necessities.

The ECB has publicly committed to a high standard of privacy for the digital euro, aiming to provide a level of privacy comparable to, if not exceeding, that offered by current mainstream electronic payment solutions like card payments or bank transfers (ecb.europa.eu). The proposed design includes features to enhance privacy:

  • Privacy-Enhancing Technologies (PETs): Exploration of technologies such as zero-knowledge proofs (ZKPs), which allow parties to prove a statement (e.g., ‘I have sufficient funds’) without revealing the underlying data (e.g., ‘my exact balance’).
  • Tiered Approach to Information: A core principle is that the central bank would have minimal access to personal transaction data. In the two-tiered model, customer identification (KYC) would be handled by intermediaries (banks, PSPs), and the central bank would only see aggregated or anonymized data, or only specific information necessary for settlement. For small-value, everyday transactions, a higher degree of privacy, approaching cash-like anonymity, is being explored, potentially through offline capabilities.
  • GDPR Compliance: As a European initiative, the digital euro’s design must fully comply with the rigorous General Data Protection Regulation (GDPR), which mandates data minimization, purpose limitation, and strong user rights over personal data. This implies that only necessary data would be collected, for specified purposes, and held for no longer than required.
  • Separation of Data: The system aims to separate transactional data from personal identifiable information, with different entities holding different parts of the data. For instance, the central bank might process transaction value, while the intermediary holds customer identity.

Despite these assurances, public skepticism and concerns persist regarding potential government oversight and the perceived erosion of financial autonomy. Transparent communication, robust legal safeguards, and demonstrable technical protections will be critical to building public trust and ensuring widespread acceptance of the digital euro’s privacy framework (European Data Protection Supervisor, 2022).

4.4 Technical and Policy Challenges

The development and implementation of a CBDC like the digital euro are fraught with complex technical and policy challenges that demand innovative solutions and extensive coordination.

Technical Challenges:

  • Scalability: A digital euro must be capable of processing millions of transactions per second, especially during peak times, to serve the entire eurozone population. This requires a robust, high-performance infrastructure that can match or exceed the capabilities of existing private payment networks like Visa or Mastercard.
  • Resilience and Security: The system must be incredibly resilient to outages, cyberattacks, and other disruptions. It must incorporate state-of-the-art cryptographic security measures to prevent counterfeiting, double-spending, and fraud. Any perceived vulnerability could undermine public trust and the currency’s stability.
  • Interoperability: The digital euro needs to seamlessly interoperate with existing national payment systems (e.g., SEPA credit transfers, instant payments), commercial bank accounts, and potentially other future CBDCs or digital assets. This ensures smooth transitions and avoids fragmentation of the payment landscape.
  • Technology Choice: Deciding between a centralized ledger system controlled by the central bank or a distributed ledger technology (DLT/blockchain) is a fundamental choice. While DLT offers decentralization and resilience, its current scalability and energy consumption for public blockchains remain significant concerns for a retail CBDC of this magnitude. The ECB has indicated a preference for a centralized system, potentially incorporating DLT elements for specific functionalities, to ensure maximum control and stability.
  • Offline Functionality: As previously discussed, enabling secure offline transactions without compromising the integrity of the currency (e.g., preventing double-spending in an offline context) presents sophisticated technical hurdles.

Policy Challenges:

  • Legal Framework: A comprehensive legal framework is essential to define the digital euro’s legal tender status, the rights and obligations of users and intermediaries, and the roles and responsibilities of the ECB and national central banks. This requires new legislation at the European level (European Commission, 2023).
  • Governance: Establishing clear governance structures for the digital euro project, involving the ECB, national central banks, and potentially EU institutions like the European Commission and Parliament, is critical for effective decision-making and accountability. The political debate surrounding the digital euro’s strategic nature and design has sometimes been contentious within the Euro Parliament (El País, 2025).
  • International Coordination: As many countries explore CBDCs, international cooperation is vital to ensure cross-border interoperability, prevent regulatory arbitrage, and develop common standards for issues like AML/CFT. This avoids a fragmented global payment system.
  • Public Acceptance and Education: Overcoming public skepticism, addressing misconceptions (e.g., fears of surveillance, replacement of cash), and effectively communicating the benefits of the digital euro are paramount for its widespread adoption. Extensive public education campaigns will be required.
  • Impact on Financial Sector Structure: Policymakers must carefully manage the potential impact on commercial banks’ business models and the broader financial intermediation landscape, ensuring a smooth transition that fosters innovation without undermining stability. The ECB aims to have a political agreement on the digital euro by early 2026 (Reuters, 2025).

The ECB’s approach involves a thorough investigation and preparation phase to systematically address these formidable technical and policy challenges, emphasizing a design that is robust, secure, privacy-preserving, and widely accessible for all euro area citizens (consilium.europa.eu).
