Inflation rose by 1.51 per cent for the week ended October 17 on the back of higher food prices. During the week, tea, mutton and arhar and manufactured food items including edible oil and gur turned expensive. Projecting inflation to touch 6.5 per cent-mark by the end of the current fiscal, the RBI in its quarterly monetary policy review on Tuesday had taken steps to suck out liquidity from banks. The apex bank had raised Statutory Liquidity Ratio (SLR), the amount of deposits that banks are to keep in government securities, cash and gold, by one percentage point to 25 per cent.
