Mumbai: The country's largest lender the State Bank of India (SBI) Tuesday said it will hike its base and prime lending rates by 25 basis points from April 25, thus making auto and housing loans dearer. The bank will increase its benchmark prime lending rate by 25 basis points (bps) to 13.25 percent per annum from the existing rate of 13 percent per annum, SBI said in a regulatory filing to the Bombay Stock Exchange. This will make lending rates, especially auto and housing loans, dearer by at least 25 basis points. The government-run lender has also announced that it will raise its base rate by 25 basis points to 8.50 percent from the existing 8.25 percent. The new rates will be effective from April 25. Base rate is the rate below which a bank cannot lend. Base rates of most other banks are at around 9 percent. Base rate of ICICI Bank, the country's largest private sector lender, is 8.75 percent.
