In this comprehensive, accessible work, Ross P. Buckley, Douglas W. Arner, and Dirk A. Zetzsche offer an ideal reference for anyone seeking to understand the technological transformation of finance and the role of regulation: the world of FinTech. They consider FinTech technologies including artificial intelligence, blockchain, BigData, cloud computing, cryptocurrencies, central bank digital currencies, and distributed ledger technology, and provide a unique perspective on FinTech as an interactive system involving finance, technology, law, and regulation. Starting with an evolutionary perspective, the authors then consider the major technologies transforming finance, arguing for approaches to balance the risks and challenges of innovation. They address the central role of infrastructure in digital financial transformation, highlighting lessons from China, India, and the EU, as well as the impact of pandemics and other sustainability crises, while considering the risks generated by FinTech. They conclude by offering forward-looking regulatory strategies to address the challenges facing our world today.
