On April 19, the U.S. Government Accountability Office (GAO) published a study examining four “subsectors” within the fintech industry—marketplace lenders, mobile payments, digital wealth management platforms, and distributed ledger technology (also known as blockchain)—highlighting the types of products and services offered and how they are regulated. The report, Financial Technology – Information on Subsectors and Regulatory Oversight, is the first in a series of planned reports on fintech, following a request by Congress for a review of issues related to the industry. From July 2016 to April 2017, GAO reviewed agency publications, guidance, final rulemakings, initiatives, and enforcement actions, and also conducted interviews with representatives from the federal prudential regulators, state supervision agencies, and trade associations in order to compile the findings in the report. The report provides an overview of the technologies associated with each subsector, identifies primary users of the products and services, notes potential benefits and risks, and highlights industry trends and current regulations and oversight. Notably, GAO stated it made no recommendations in this report.
