Historical Context
M3, also known as broad money, is a comprehensive measure of the money supply in an economy. It extends beyond the narrower definitions like M1 (physical currency and demand deposits) and M2 (which adds savings deposits and money market funds). The concept of M3 emerged in the mid-20th century as economists and policymakers sought a more detailed understanding of the liquidity in an economy. This broader definition helps gauge the total amount of money available, influencing inflation, interest rates, and economic growth.
Components of M3
M3 includes:
- M1: Physical currency, demand deposits.
- M2: M1 plus savings deposits, small-denomination time deposits, and retail money market mutual funds.
- Additional Deposits: Large time deposits, institutional money market funds, short-term repurchase agreements, and other larger liquid assets.
Importance in Economics
M3 is crucial for understanding an economy’s liquidity. Policymakers and economists use it to:
- Measure economic activity and predict inflation.
- Formulate monetary policy.
- Assess financial stability.
Key Events in the History of M3
- 1960s-1970s: M3 gained prominence during periods of high inflation and economic turbulence.
- 2006: The Federal Reserve ceased publishing M3 data, citing the cost of data collection relative to its utility.
- Post-2008 Financial Crisis: Renewed interest in M3 arose as economists sought comprehensive liquidity measures.
Mathematical Models and Formulas
The calculation of M3 is straightforward:

Applicability and Examples
Use in Policy Making
Central banks use M3 to:
- Determine monetary policy (interest rates, money supply).
- Forecast inflation and GDP growth.
- Assess the banking sector’s health.
Examples
- Eurozone: The European Central Bank (ECB) uses a definition similar to M3 for its monetary aggregates.
- India: The Reserve Bank of India (RBI) tracks broad money as part of its monetary policy framework.
Considerations
Limitations of M3
- Not universally tracked: Different countries may have different definitions and may not always report M3.
- Lagging indicator: Changes in M3 may lag behind economic events.
Comparisons with M4 and M5
- M4 and M5: Even broader measures, may include more categories of financial instruments, though less commonly used and standardized.
Interesting Facts
- Why the Fed Stopped Reporting M3: In 2006, the Fed stopped publishing M3 due to the high cost of data collection, leading to debates about its importance.
Inspirational Story
In the 1980s, economist Milton Friedman emphasized the importance of controlling the money supply (including broad measures like M3) to manage inflation, significantly influencing modern monetary policy.
