Helped by softening prices of food items, the retail inflation declined to 5.52 per cent in October, the lowest since the new series of data was introduced in January 2012.

The Reserve Bank has of late started targeting retail inflation, while deciding on its bi-monthly monetary policy. RBI has been targeting a retail inflation of 8 per cent by March 2015 and 6 per cent by March 2016.

RBI's next monetary policy is due on December 2, 2014. "The inflation data is very encouraging. It is little below what the market was expecting. Lower base rate and softening food prices also helped.
"It is building a case for a rate cut. But whether the Reserve Bank will do in December or not, it is a little more wait and watch, but a rate cut is very possible," said Abheek Barua, Economist with Indian Council for Research on International Economic Relations (ICRIER).
