Outline of Final Research Achievements

Based on the analysis of data and information from field surveys and relevant institutions, our research found that the imposition of the interest rate ceiling has led to a decline in the average credit costs for microfinance borrowing households. However, the ceiling imposition could result in credit rationing for relatively low-income households. This result is consistent with international experience. The research also confirmed an increase in the average loan amount for relatively low loan amounts. The analysis indicated that higher loan amounts resulted in a higher debt burden (measured as the debt service-to-income ratio). Consequently, for households with relatively small borrowing amounts, the debt burden may have increased after the ceiling imposition. Our research also confirmed the important role of financial literacy in reducing the debt burden among microfinance borrowers.
