It said in response to the reduction in policy repo rate by 150 basis points during January 15, 2015, through April 5, 2016, the median base rate of banks declined by 60 basis points as against a higher decline of 92 bps in median term deposit rates.
So far in financial year 2016-17, there has hardly been any transmission of a reduction in the policy rate to the actual lending rates charged to customers, it said.
The report said while the cost of funding by banks has declined somewhat, leading to a decline in shorter maturity marginal cost of funds based lending rate (MCLR), there has been an increase in the term premia in respect of term loans of one year and above, thereby attenuating the transmission to actual lending rates charged to customers.
"Moreover, banks may have been loading a higher credit risk premia on their new customers in order to attain their desired return on net worth in a rising NPA environment," it said.
The consequent rise in the spread is reflected in a near unchanged weighted average lending rate (WALR) in respect of both outstanding and fresh rupee loans during 2016-17 up to June, it said.
RBI said under marginal cost of funds based lending rate (MCLR) the transmission to WALR is expected to improve on the assumption that the marginal cost of funds is more sensitive to changes in the policy rate than the average cost of funds.
