ECB's Digital Euro Development: An In-Depth Look at the Rulebook's Progress

The European Central Bank (ECB) has made significant strides in the development of the digital euro, particularly through the efforts of its Rulebook Development Group (RDG). This team has been instrumental in designing the framework for digital euro payments, focusing on a comprehensive set of rules, standards, and procedures.

The RDG's work, initiated in January 2023, has encompassed various aspects of the digital euro's implementation, including its functional and operational models, high-level architecture and standards, and the rights and obligations of participants under the proposed legislation. Representatives from industry advocacy groups and national central banks form part of the RDG, ensuring a diverse and inclusive approach to the rulebook's development​​​​.

Since the last update in June 2023, the RDG has successfully drafted the initial chapters of the digital euro rulebook. This draft covers key areas such as the functional and operational models, detailing the end-to-end flows for all use cases and services related to the digital euro. Additionally, it addresses the technical scheme requirements, which include a high-level architecture and potential standards for the digital euro landscape. The adherence model, another crucial component, delineates the rights and obligations of scheme members in alignment with the draft legislation​​.

The RDG is currently reviewing the draft rulebook, with plans to make adjustments based on feedback received during this process. This step ensures that the rulebook remains flexible enough to accommodate any future changes and aligns with the outcomes of the digital euro legislative process. The RDG's ongoing work includes finalizing the rulebook and adding sections on user experience minimum requirements, branding and communication standards, certification, testing and approval procedures, internal rules, risk management, interoperability, and implementation specifications​​​​.

In November 2023, the ECB transitioned into the "preparation phase" for the digital euro, following the conclusion of the investigative phase. This two-year phase involves finalizing the rules, running experiments, and gathering feedback, all while a legislative framework is being concurrently designed. The draft legislation has received mixed reviews from various sources, highlighting the complex nature of establishing a central bank digital currency​​​​.

The ECB emphasizes the importance of collaboration between public and private entities in implementing the digital euro framework. Intermediaries, such as banks and other financial institutions, will play a critical role in bridging the gap between the central bank and end-users. They might also engage with third-party services to fulfill their roles, although these third parties will not be direct actors in the scheme. This collaborative network forms the backbone of the digital euro ecosystem, ensuring regulated and seamless transactions within this new digital currency framework. As the preparation phase progresses, the RDG plans to expand the rulebook to cover areas like user experience, branding, certification, and interoperability​​.

In conclusion, the ECB's RDG is at the forefront of shaping the digital euro's future, ensuring that its implementation is guided by a thorough and adaptable set of rules and standards. This collaborative and inclusive approach, involving both public and private sectors, is crucial for the successful integration of the digital euro into the broader financial ecosystem.
