Money serves as the standard of deferred payment. Deferred payments refer to payments made on loans, salaries, pensions, insurance premium, interests, and rents. The necessary condition for deferred or credit payment is that the amount of repaid money should be the same as it was at the time of purchase of the good. Since all the goods and services can be expressed in terms of money, it makes the future payments easy and functional which makes money the basis for generating credit in the economy.
