Does Regulatory Supervision Curtail Microfinance Profitability and Outreach?

We combine two datasets to examine whether the scale of an economy’s banking system affects the profitability and outreach of microfinance institutions. We find evidence that competition matters. Greater bank penetration in the overall economy is associated with microbanks pushing toward poorer markets, as reflected in smaller average loans sizes and greater outreach to women. The evidence is particularly strong for microbanks that rely on commercial-funding, use traditional bilateral lending contracts (rather than group lending methods favored by microfinance NGOs), and take deposits. We consider plausible alternative explanations for the correlations, including relationships that run through the nature of the regulatory environment and the structure of the banking environment, but we fail to find strong support for these alternative hypotheses.
