The Reserve Bank of India has brought a new methodology of setting lending rate by commercial banks under the name Marginal Cost of Funds based Lending Rate (MCLR). It will modify the existing base rate system from April 2016 onwards.

As per the new guidelines by the RBI, banks have to prepare Marginal Cost of Funds based Lending Rate (MCLR) which will be the internal benchmark lending rates. Based upon this MCLR, interest rate for different types of customers should be fixed in accordance with their riskiness.
As per the new guidelines, banks have to set five benchmark rates for different tenure or time periods ranging from overnight (one day) rates to one year.
The new methodology uses the marginal cost or latest cost conditions reflected in the interest rate given by the banks for obtaining funds (from deposits and while borrowing from RBI) while setting their lending rate. This means that the interest rate given by a bank for deposits and the repo rate (for obtaining funds from the RBI) are the decisive factors in the calculation of MCLR.
