• Money supply is the total stock of money in circulation among the public.
  • It includes currency notes, coins, and public deposits in banks.
  • RBI publishes figures for four alternative measures of money supply.
M1 (Most Liquid)
  • M1 = Currency with the Public + Demand deposits of public with banks.
  • Represents the most liquid forms of money.
M2
  • M2 = M1 + Savings Deposits with Post Office Savings Bank.
  • Expands M1 by adding less liquid savings deposits.
M3 (Broad Money, Most Commonly Used)
  • M3 = M1 + Time deposits of public with banks.
  • Includes less liquid time deposits.
  • Also called “aggregate monetary resources”.
M4 (Least Liquid)
  • M4 = M3 + Total deposits with Post Office Savings Bank.
  • The broadest measure, incorporating all deposits.
