Microfinance institutions (MFIs) have gained prominence in South Africa's informal markets as a means to support women entrepreneurs. A mixed-methods approach combining quantitative data from MFI client surveys with qualitative interviews in selected informal market zones. The findings suggest that MFIs play a crucial role in fostering sustainable economic growth and social empowerment among women entrepreneurs in South Africa's informal markets. Further research should explore the long-term impacts on community development and the potential to scale these programmes across broader regions of the country.
