Wholesale Price Index (WPI)

Why in news?

• Inflation in wholesale prices slowed marginally to 11.2% in July, from June’s 12.1%, with the pace of price gains in primary articles, food as well as fuel and power moderating.

About WPI:

• Wholesale Price Index measures the changes in the prices of goods sold and traded in bulk by wholesale businesses to other businesses.
• WPI is unlike the Consumer Price Index (CPI), which tracks the prices of goods and services purchased by consumers.
• To put it simply, the WPI tracks prices at the factory gate before the retail level.

Who publishes WPI in India?

• WPI numbers are released by the Economic Advisor in the Ministry of Commerce and Industry.
• Analysts use the numbers to track the supply and demand dynamics in industry, manufacturing and construction.
• An upward surge in the WPI print indicates inflationary pressure in the economy and vice versa.
• The quantum of rise in the WPI month-after-month is used to measure the level of wholesale inflation in the economy.

What is the difference between WPI and CPI inflation?

• While WPI keeps track of the wholesale price of goods, the CPI measures the average price that households pay for a basket of different goods and services.
• CPI is released by the National Statistical Office (NSO), While WPI numbers are released by the Economic Advisor in the Ministry of Commerce and Industry.
• Even as the WPI is used as a key measure of inflation in some economies, the RBI no longer uses it for policy purposes, including setting repo rates.
• The central bank currently uses CPI or retail inflation as a key measure of inflation to set the monetary and credit policy.

Calculation of WPI

• With an aim to align the index with the base year of other important economic indicators such as GDP and IIP, the base year was updated to 2011-12 from 2004-05 for the new series of Wholesale Price Index (WPI), effective from April 2017.
• The monthly WPI number shows the average price changes of goods usually expressed in ratios or percentages.
• The index is based on the wholesale prices of a few relevant commodities available.
• The commodities are chosen based on their significance in the region.
• These represent different strata of the economy and are expected to provide a comprehensive WPI value.
• The advanced base year 2011-12 adopted recently uses 697 items.
