Definition and Components
M1 Money Supply is a category of money supply that includes the most liquid forms of money—those that are easily accessible for transactions. It encompasses physical currency and coin held by the public, demand deposits in banks and credit unions, traveler’s checks, and other checkable deposits.
M1 = C + DD + TC + OCD
where:
- \( C \) = Physical currency and coins
- \( DD \) = Demand deposits
- \( TC \) = Traveler’s checks
- \( OCD \) = Other checkable deposits
Calculation Methods
The calculation of M1 Money Supply involves adding together the values of its components:
- Physical Currency and Coins: Evaluating the total amount in private circulation.
- Demand Deposits: Summing up all immediate, accessible bank deposits.
- Traveler’s Checks: Including checks issued by banks for use in travel.
- Other Checkable Deposits: Aggregating all other deposits that can be written against.
Historical Context and Development
The concept of M1 Money Supply became prominent in economic theory following the Keynesian revolution in economics during the 20th century. Over time, economists and policymakers have used M1 as a critical measure to manage and understand economic performance and inflation.
Economic Implications
M1 is a key indicator of liquidity in an economy. It is closely monitored by central banks and national economic authorities. An increase in M1 can signal easier access to money, potentially leading to higher consumer spending. Conversely, a decrease might indicate tighter monetary conditions.
Comparisons with M2 and M3
- M2: Includes all of M1, plus savings deposits, small-denomination time deposits (certificates of deposit under $100,000), and retail money market mutual funds.
- M3: Includes all of M2, along with large time deposits, institutional money market funds, short-term repurchase agreements, and larger liquid assets.

Summary
M1 Money Supply is a crucial economic measure that reflects the most liquid segment of the money supply, including physical currency, demand deposits, and other highly liquid assets. It plays a significant role in economic analysis and policy formulation, offering insights into the availability of money for consumer transactions and overall economic conditions. Proper understanding and calculation of M1 are essential for both economists and policymakers to monitor economic health and devise effective monetary policies.
