This book exemplifies the potential of FinTech to deliver important economic and societal gains, such as enhancing competition and financial inclusion to deliver tailored financial products and services at more affordable prices and at greater convenience. The emergence of FinTech directly challenges the business models of incumbent financial intermediaries like banks, which are adapting by developing their own FinTech offerings and partnering with FinTech and large technology firms. FinTech also constitutes both known and unknown risks to financial stability and challenges regulators to evaluate whether existing regulations are sufficient. The emergence of FinTech as a global phenomenon requires insightful cross-country analysis and different perspectives to evaluate its development and associated opportunities and challenges. This book will be of interest to practitioners, regulators and students of this essential enabling technology that is a major component of the Fourth Industrial Revolution.
