The country's largest lender State Bank of India has fixed its base rate at 7.5 per cent, the new lending benchmark rate. The Bank will not provide any credit, including housing, auto or corporate loans below this rate. However, it will not apply to concessional loans for agriculture, exports and other specified sectors. Several Public Sector Banks have also come out with the base rate for lending. Punjab National Bank, Central Bank of India, Union Bank and Indian Bank have fixed the Base Rate at 8 per cent. Other Banks will announce their base rates today, taking a cue from the largest Public Sector Bank, State Bank of India.
