Financial Techonology has disrupted financial systems globally, dramatically changing the current banking paradigm, and regulatory agents lag behind its constant growth and development. The paper explains how FinTech affects financial regulation from a Public Law perspective. Uruguay stands out amongst Latin American countries due to its developed technological connectivity and a responsive regulator, with a diversity of FinTech issues being legislated in recent times. Analysing its case, therefore, represents an opportunity to consider whether it is pertinent for the State to actually regulate this technology and its limits to do so, both from a legal and a practical perspective. Finally, the paper considers the largest challenges facing FinTech regulation in the forthcoming years.
