in this video we have discussed about crr and slr. cash reserve ratio (CRR) is the percentage of a bank's total deposits that it needs to maintain as liquid cash. This is an RBI requirement and the cash reserve is kept with the RBI. A bank does not earn interest on this liquid cash maintained with the RBI and neither can it use this for investing and lending purposes. Statutory Liquidity Ratio or SLR is a minimum percentage of deposits that a commercial bank has to maintain in the form of liquid cash gold or other securities. These are not reserved with the Reserve Bank of India (RBI) but with banks themselves.The SLR is fixed by the RBI.
