Money Supply refers to total volume of money held by public at a particular point of time in an economy.
M1=currency held by public + Demand deposits + other deposits with Reserve Bank of India.
M2=M1+saving deposits with post office saving bank
M3=M1+net time deposit with the bank
M4=M3 + total deposits with post office saving bank excluding national saving certificate.


It refers to, currency with the public (notes +coins) and cash reserve of banks.


Let us understand the process of credit creation with the following example.
Suppose there is an initial deposit of Rs. 1000 and L.R.R. is 20% i.e., the banks have to keep Rs. 200 and lend Rs. 800/-. All the transactions are routed through banks. The borrower withdraws his Rs. 800/- for making payments which are routed through banks in the form of deposits account. The Bank receives Rs. 800/- as deposit and keeps 20% of Rs.800/- i.e., Rs.160/- and lends Rs.640/- . Again the borrower uses this for payment which flows back into the banks thereby increasing the flow of deposits.


Money Multiplier = 1/LRR. In the above example LRR is 20% i.e., 0.2, so money multiplier is equal to 1/0.2=5.
Why only a fraction of deposits is kept as Cash Reserve?
a) All depositors do not withdraw the money at the same time.
b) There is constant flow of new deposits into the banks.
