Financial consumer protection aims to promote fair transactions between financial service providers and consumers such as individuals and small and medium-sized enterprises, thereby promoting financial inclusion achievement, with four basic principles guiding the behavior of service providers, namely: (1) fair treatment of consumers, (2) transparency of information, (3) resolution of complaints complaints, and (4) supervisory powers. In this study, we analyze all four aspects of financial consumer protection as well as the impact of each of these on financial inclusion. Research findings from 87 countries and information from the World Bank's new database on financial consumer protection policies (World Bank, 2017) show that, while regulations on fair treatment of consumers and complaint settlement have an impact on both access to and use of financial services, requirements on information transparency and supervisory powers only affect access to finance.
