Cash Reserve Ratio (CRR): The fraction of their deposits which the commercial banks are required to keep with RBI.
Statutory Liquidity Ratio (SLR): The fraction of their total demand and time deposits which the commercial banks are required by RBI to invest in specified liquid assets.

The RBI publishes figures for four alternative measures of money supply, viz. M1, M2, M3 and M4. They are defined as follows:
M1 = CU + DD;
M2 = M1 + Savings deposit with Post Office savings banks;
M3 = M1 + Net time deposits of commercial banks;
M4 = M3 + Total deposits with Post Office savings organisations (excluding National Savings Certificates).
where, CU is currency (notes plus coins) held by the public and DD is net demand deposits held by commercial banks. M1 and M2 are known as narrow money. M3 and M4 are known as broad money. These gradations are in decreasing order of liquidity. M1 is most liquid and easiest for transactions whereas M4 is least liquid of all. M3 is the most commonly used measure of money supply. It is also known as aggregate monetary resources.
