Equation of Exchange

The equation of exchange is a foundational concept in monetary economics, expressed as MV equals PQ, where M is the money supply, V is velocity, P is the price level, and Q is the quantity of goods or services. In the context of digital assets, this formula helps quantify the necessary token supply to facilitate a specific volume of network transactions.

It serves as a framework for understanding how changes in token velocity impact the equilibrium price of a digital asset. If transaction volume increases, the token price or the velocity must adjust to maintain equilibrium.

This model is frequently applied by researchers to assess whether a token is overvalued or undervalued relative to its actual network usage. By isolating variables, analysts can simulate various economic scenarios for protocol growth.

It highlights the tension between speculative demand and functional utility. Without understanding this equation, it is difficult to determine the long-term viability of a token economy.
