Advances in technology and the widespread use of the Internet and mobile communication devices have helped fuel the rise of traditional financial services provided by non-traditional technology-enabled providers, often referred to as fintech. This report addresses fintech payment, lending, wealth management, and other products. GAO assesses 1) fintech benefits, risks, and protections for users; 2) regulatory oversight of fintech firms; 3) regulatory challenges for fintech firms; and 4) the steps taken by domestic and other countries' regulators to encourage financial innovation within their countries. GAO reviewed available data, literature, and agency documents; analyzed relevant laws and regulations; and conducted interviews with over 120 federal and state regulators, market participants, and observers, and regulators in 4 countries with active fintech sectors and varying regulatory approaches.
