A commercial bank is a financial institution that accepts deposits and offers services like checking and savings accounts. It makes loans to businesses, individuals, and for mortgages. Commercial banks are where most people do their everyday banking, as opposed to investment banks. Commercial banks play important roles in India by providing capital and assistance to promote trade, agriculture, industry, and foreign trade. They support economic development through capital formation, increasing production, developing transportation, and accelerating the rate of capital formation by providing finance and credit.
