The increasing capacity of digital networks and computing power, together with the resulting connectivity and availability of “big data”, are impacting financial systems worldwide. They transform the structure and performance of financial markets and the business models of banks and other financial service providers. The new open access book The Future of Financial Systems in the Digital Age:  Perspectives from Europe and Japan, edited by DIJ director Franz Waldenberger and principal researcher Markus Heckel, brings together leading scholars, policymakers, and regulators from Japan and Europe to analyse the digital transformation of the financial system. The authors study the impact of digitalization on the financial system, including transaction costs, digital and blockchain-based currency systems, algorithmic trading, the use of cashless payments, the challenges of regulatory oversight, and the transformation of banking business models. The book and its individual chapters can be downloaded for free here. A Japanese version of the book has been published as デジタル時代の金融システム―欧州と日本からの視点 by the Kinzai Institute for Financial Affairs.
