The Cash Reserve Ratio in India is decided by RBI's Monetary Policy Committee in the periodic Monetary and Credit Policy. The Reserve Bank of India takes stock of the CRR in every monetary policy review, which, at present, is conducted every six weeks. CRR is one of the major weapons in the RBI's arsenal that allows it to maintain a desired level of inflation, control the money supply, and also liquidity in the economy. The lower the CRR, the higher liquidity with the banks, which in turn goes into investment and lending and vice-versa. Higher CRR can also negatively impact the economy as lesser availability of loanable funds, in turn, slows down investment. It thereby reduces the supply of money in the economy. The Reserve Bank of India or RBI mandates that banks store a proportion of their deposits in the form of cash so that the same can be given to the bank's customers if the need arises. The percentage of cash required to be kept in reserves, vis-a-vis a bank's total deposits, is called the Cash Reserve Ratio. The cash reserve is either stored in the bank's vault or is sent to the RBI. Banks do not get any interest on the money that is with the under the CRR requirements.
