M4 is a comprehensive measure of the money supply that encompasses M3 along with other non-liquid financial instruments such as treasury bills and commercial paper. By integrating these additional elements, M4 provides a broad view of the total money available in an economy, which includes highly liquid and less liquid forms of financial assets.
Components of M4
- M3: M3 includes M2 (which includes M1) along with large time deposits, institutional money market funds, and other larger liquid assets.
- Treasury Bills: Short-term government securities with a maturity of less than one year.
- Commercial Paper: Unsecured promissory notes issued by companies to finance short-term liabilities.

Importance of M4 in Economics
Measuring Money Supply
M4 is used to gauge the total money supply within an economy, which is crucial for forming economic policy, particularly monetary policy. A broad measure like M4 can provide insights into future levels of inflation, interest rates, and economic growth.
Policy Formulation
Economists and policymakers rely on M4 to design strategic measures capable of stabilizing and stimulating the economy. By understanding the total availability of money in the financial system, they can better manage credit availability, control inflation, and stabilize the financial markets.
Historical Context
Origin and Development
The concept of M4 evolved from the need to capture a broader spectrum of money in an economy. While traditional measures like M1 and M2 were sufficient for basic analysis, the inclusion of non-liquid assets in M4 provided a more comprehensive overview of the monetary framework.
Comparison to Other Money Supply Measures
- M1: Includes only the most liquid assets, such as cash and checking deposits.
- M2: Includes M1 plus savings deposits, money market funds, and other time deposits.
- M3: Builds upon M2 by adding large time deposits and institutional money market funds.
Special Considerations
Liquidity vs. Non-liquidity
While M4 offers a broad perspective of the money supply, it includes assets that do not have the same liquidity as those in M1 or M2. Policymakers should consider the varying degrees of liquidity when using M4 for decisions affecting short-term economic conditions.
