Banks generate maximum revenue by lending to customers because banks pay maximum 6% interest on customer FDs where they charge 10-15% interest on loans. The highest interest is charged on credit card loans where they charge compound interest. Banks earn revenue from your details and many more. On the other hand, the bank account holders are affected because the value of money has started decreasing day by day in relation to the goods due to the bank not giving good interest.
