Mumbai, Feb 27 As banks’ chase for customers to collect cheap deposits is not fructifying, they are forced to offer inflation-beating real interest rates on fixed deposits now, and state-run banks led by Punjab & Sind Bank top the chart offering a cool 8-8.50 per cent per annum. Banks are forced to offer inflation-beating deposit rates for a tenor ranging from 200 to 800 days as credit growth has been far outpacing deposit mobilization throughout this fiscal, leading to a funding crunch. Even at the lowest 7 per cent, fixed deposit pricing is positive for customers because even after a surprise spurt in retail inflation for January at 6.52 per cent, the real rates are in the green.
