An inflationary gap is a macroeconomic concept that describes the difference between the current level of real gross domestic product (GDP) and the anticipated GDP that would be experienced if an economy is at full employment.

It reduces the supply of money and credit creation capabilities of commercial banks. Due to lesser supply of money, the Aggregate Demand comes down and the economy attains equilibrium situation
