Wholesale inflation stood at 4.53 per cent in August, government data showed on Friday. That marked the lowest level of price increase rate recorded since April this year. In July, wholesale inflation was at a four-year high of 5.09 per cent. Softening of food prices, especially vegetables, led to easing in the overall WPI figure. Wholesale inflation, however, quickened on an annual basis, from 3.24 per cent in August 2017. Wholesale inflation or headline inflation is determined by the Wholesale Price Index (WPI), and takes into account the rate of increase in wholesale prices in the country.
