## MINISTER OF STATE IN THE MINISTRY OF FINANCE (SHRI ARJUN RAM MEGHWAL)

(a) to  (b) : As per the latest monthly data for June 2016, the Wholesale Price Index with base 2004-05 stood at 182.0 and the Consumer Price Index (Combined) with base 2012  has reached 130.1. The headline inflation based on the WPI and CPI was 1.62 per cent and 5.77 per cent respectively for June 2016. WPI inflation for the month of June 2016 has been the highest since last 20 months. The difference between WPI and CPI index numbers is partly owing to variation in the  scope and structure of the two  baskets. The WPI  basket assigns significantly  larger  weight  to  tradeable  commodities  and  comparatively  lower  weight  to  food  items,  while  CPI basket assigns higher weight to food items and includes services like health and education. While the prices of tradable commodities are largely influenced by international prices, the prices of non-traded food and services like education and health services are determined by domestic prices.  The decline in global commodity prices, in particular crude oil price, has been the key reason for persistently lower level of WPI based inflation.

(c) to (e) : The rate of inflation as measured by WPI and CPI (Industrial Workers) during the last six months and its  comparison  with  the  corresponding  period  of  2014  and  2015  is  given  in  Table  1  below.  The  difference  in scope,  items  in  the  respective  basket,  weighting  structure,  price  quotations  and  gap  in  base  year  leads  to variation in the inflation estimates of the two series.
