The document summarizes the types of banks in India. There are four main categories: central banks, commercial banks, regional rural banks, and cooperative banks. The central bank is the Reserve Bank of India. Commercial banks include public sector banks (like State Bank of India), private sector banks (like HDFC and ICICI), and foreign banks. Regional rural banks were established to provide financial services in rural areas. Cooperative banks are organized at the state level and provide loans to agriculture and related sectors. Each category plays an important role in India's banking system.
