Fintech, regtech and suptech. Institutional challenges to the supervisory architecture of the financial markets

The use of technology in the financial sector has deeply transformed business models, products and services, and is gradually affecting regulation and supervision. After focusing on the main current trends in Fintech regulation within the EU, and on the related phenomenon of Regtech, this chapter aims to explore the recent developments in Suptech and to assess how the employment of technology-enabled solutions is changing the way authorities perform their functions. The spread of Suptech could enhance supervisory capabilities while fostering a more flexible and collaborative approach towards the regulated institutions, representing a paradigm shift in the relationship between regulation and supervision. These changes pose new challenges to the current institutional framework and to the underlying public law accountability principles.
