Calculate M1 Money Supply

What is M1 Money Supply?

M1 money supply refers to the most liquid form of money in an economy. It includes physical currency (coins and banknotes) and demand deposits (checking accounts). M1 is considered the most liquid component of money supply because it can be easily converted into spending.

The Federal Reserve tracks M1 as part of its monetary aggregates, which help economists understand the money supply and its impact on economic activity. M1 is often used as a leading indicator of economic conditions and inflationary pressures.

Components of M1

M1 money supply consists of two main components:

1. Currency in circulation: This includes all physical money in the form of coins and banknotes that are in use.
2. Demand deposits: These are checking account balances that can be accessed immediately without notice.

Other monetary aggregates like M2 include savings deposits and money market funds, but M1 focuses only on the most liquid forms of money.

How to Calculate M1

The M1 money supply is calculated by adding the total currency in circulation to the total demand deposits. The formula is:

Where:

• Currency in Circulation - The total amount of physical money (coins and banknotes) in the economy
• Demand Deposits - The total checking account balances that can be accessed immediately

The result is expressed in the currency unit of the country (e.g., US dollars, euros).

Worked Example

Let's calculate M1 for a hypothetical economy:

• Currency in circulation: $1,200,000,000
• Demand deposits: $8,500,000,000

Using the formula:

So, the M1 money supply for this economy is $9.7 billion.
