From Euro to Digital Euro: A Survey of Literature

Over the last decade, discussions about digital currencies have attracted an increasing number of researchers, financial institutions, and central banks. Later, the central bank digital currency became a hot topic, with major central banks investigating and even designing pilot projects in the field. More recently, the European Central Bank has become increasingly interested in a digital euro. The paper investigates the relevant literature on digital currencies, focusing on the digital euro, particularly from the European Central Bank's perspective, and analyses the implications for monetary policy, the payment system, the banking system, and related areas. Drawing on a bibliometric analysis based on the Web of Science database, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol and VOSviewer software, the paper sheds light on the main trends, concerns, and areas of investigation related to the possible adoption of a digital euro.
