A government committee has suggested raising interest rates on post office savings deposits to 4 per cent. The interest rate at present is 3.5 per cent. The suggestion, if implemented, will benefit lakhs of small depositors. The committee on small savings also recommended linking returns on other small savings schemes with interest rates on government securities. It has also suggested that Kisan Vikas Patra be withdrawn and the annual investment limit for the popular Public Provident Fund be raised to one lakh rupees from 70,000 rupees at present.
