This book offers a deeper understanding of digitisation and innovative technologies in the financial sector. It focuses on a digital version of sovereignly created money that is accessible to the broad public. This central bank digital currency (CBDC) raises several questions. Will CBDC lead to public surveillance of the citizens? What is digital money in the legal sense? And what is the difference to already existing forms of digital money? This book addresses main questions associated with central bank digital currency by providing background information as well as in-depth analyses.

The book introduces a basic understanding of innovative technologies such as the distributed ledger technology. It shows how a system of money can be created and what roles each participant has. Taking an economic point of view, the book demonstrates the monetary policy in the euro area and examines how a digital version of public money could affect the transmission mechanism as well as the financial stability. Could CBDC lead to a "digital bank run"? Could it replace the established financial intermediaries such as banks? What would that mean to the economy?
