The financial system is currently confronted with tremendous challenges from the global economy, trade, politics, demographics, and most recently from enormous technological advancements. These developments have the capacity to change the existing financial system fundamentally. This book addresses how technological developments and digitalization will impact the future of financial systems.  This book is based on the results of a series of ten roundtables with high-level experts on the future of the financial system. Experts from academia, supranational institutions, central banks, commercial banks, regulators, start-ups, technology companies, venture capital firms, think tanks, foundations, and other visionaries from five continents developed potential scenarios of the financial system 2030 over a time horizon of five years. The book presents the results of these discussions, which are structured along the ‘Vaduz Architecture’. This newly introduced concept distinguishes different dimensions for the future financial system, including information technologies, nation states and (de-) regulation.
