Overdraft (OD) facility is for current account holders wherein the customer can draw excess amount than what is standing to their credit. This means that the bank permits the customer to debit his current account below zero. But, the customer can withdraw only up to a specified limit.
Granting of loans is among the major functions which commercial banks perform. Post maintaining cash reserves as per RBI norms, banks can lend their deposits to those in need. Banks provide such loans and advances against approved security for productive purposes so as to earn interest. Cash Credit and Overdraft are two such short-term loan arrangements.
