The amount a current account holder is allowed to withdraw in excess of the balance in his account is _______

An overdraft is the amount a current account holder is allowed to withdraw in excess of the balance in his account. In simple terms, it's a type of loan that a bank provides to a customer, allowing them to spend more money than they have in their account. The customer is then charged interest on the amount they have borrowed, and they are expected to repay it. An overdraft can be a useful tool for managing cash flow and covering unexpected expenses, but it's important to understand the terms and conditions, including the interest rate and any fees, before using one.
