WPI has a maximum weight of 64.23% for manufactured goods, while CPI’s maximum weight of 45.86% is assigned to food and beverages.
What changes have been observed in the WPI basket?
The WPI basket has weightings of 22.62%, 13.15% and 64.23% for commodities, fuel and electricity and manufactured goods, respectively.

What change is proposed in WPI data collection?
WPI aims to measure dynamic price movements in wholesale purchases by traders. To take into account structural changes in the economy, it is proposed to change the reference year from 2011-2012 to 2017-2018 and to revise the basket of items from 697 to 1,176 to include products such as plants medicines, thumb drives, gym equipment, and elevators.
Why is the composition of the data changed?
The representative sample of goods would then be more reliable and relevant to current production trends. The WPI will better reflect the trend of price changes of most intermediate goods or raw materials and reveal its impact on the cost of production, indicating the likely change in cost inflation. Thus, inflationary pressures in terms of WPI, which are addressed primarily through government supply management, can best be combated through appropriate fiscal policies.
What is the anomaly in the WPI and CPI trends?
The WPI trend should ideally be reflected in the CPI as well. But the WPI was recently seen to increase at more than double the rate of the CPI. Does this mean that retailers have not passed on the cost of the products? It could also mean that the prices of certain products are not reflected in the CPI. The classic case is where the government buys foodgrains at the minimum support price and distributes them free to the poor.
