RBI Governor Raghuram Rajan, who has been under fire for keeping the interest rates high for long, is targeting to keep CPI inflation at 8 per cent in January 2015 and reduce it further to 6 per cent by 2016.
India's economic growth has slipped to sub-5 per cent in 2013-14 and 2012-13 fiscals. In the current financial year, RBI estimates the growth to be 5.5 per cent.
