Retail inflation in March is estimated to have edged higher, driven largely by rising fuel prices, economists said. Consumer Price Index (CPI) inflation is pegged at a 13-month high of 3.5% year-on-year for March, according to the median estimate of an FE poll of economists. Headline retail inflation stood at 3.2% in February and 2.75% in January. If realised, this would mark the 14th consecutive month that inflation remains below the Reserve Bank of India’s (RBI) medium-term target of 4%.
