Commercial banks occupy a dominant position in the money market and form the largest component of any country's banking structure. They are the oldest, largest, and fastest growing financial institutions in India. Commercial banks play a major role in economic growth by mobilizing savings, providing short-term loans and credit, and facilitating trade and business activity through services like checking accounts and lending. They act as reservoirs that collect savings from households and allocate those funds as loans to businesses and individuals for productive investment and use.
