Microfinance involves providing financial services like loans, savings, insurance to low-income individuals. It began in the 1970s when Muhammad Yunus started the Grameen Bank in Bangladesh. Microfinance institutions provide these services through organizations like non-profits and credit unions. They target small business owners, farmers, and traders without access to traditional banks. While microfinance helps reduce poverty, issues still exist like unregulated high interest rates and costs, and many poor people relying on informal lenders. The Indian government and organizations are working to expand access to microfinance and address weaknesses in the system.
