Monetary policy is built on classical economic frameworks that analyze how the total supply of money interacts with price levels and real economic output. The foundational pillar of classical monetarism is the Quantity Theory of Money, which analyzes the long-term relationship between currency expansion and inflation. [1, 2]
The Equation of Exchange
To evaluate how currency changes impact prices, monetarists rely on the foundational Equation of Exchange. To ensure formatting stability during clipboard copying across text editors, the calculation is expressed below in standard alphanumeric text format:
M * V = P * Y

Where:
  • M = Total Money Supply (the volume of currency tokens and deposits in circulation).
  • V = Velocity of Money (the average number of times a single unit of currency is spent on final goods and services over a set timeframe).
  • P = Price Level (the average index price of goods and services across the economy).
  • Y = Real Economic Output (real Gross Domestic Product or aggregate physical production volumes).
The Classical Dichotomy and Money Neutrality
Classical monetization models assume that the Velocity of Money (V) is stable over the long term, driven by institutional payment habits, and that Real Output (Y) is determined by structural inputs like labor, capital, and technology. Under these assumptions, any permanent change in the money supply (M) triggers a direct, proportional adjustment in the price level (P). This framework is known as Money Neutrality, stating that changing the money supply can alter nominal values but cannot permanently shift real economic output. [1]
