The Ministry of Commerce has also announced updates to the WPI framework, including a revised item basket and the introduction of new price indices.

Wholesale Price Inflation Sees Significant Increase

In May, wholesale price inflation escalated to 9.68%, up from 8.26% in April, primarily driven by a notable rise in fuel, power, manufactured goods, and food prices. The inflation rate for fuel and power soared to 30.33% in May, compared to 24.89% in the previous month. Specifically, crude petroleum inflation reached 61.51% in May, an increase from 56.31% in April. Analysts attribute this sharp increase in wholesale price index (WPI) inflation to the ongoing crisis in West Asia and the blockade of the Strait of Hormuz, a crucial route for crude oil imports.

Food article inflation also rose to 3.60% in May, up from 2.43% in April, while inflation for manufactured products increased to 7.48% from 6.68%. The latest WPI data was released following the revision of the base year from 2011-12 to 2022-23. New price indices, including the Output Producer Price Index and a trial Input Producer Price Index for manufacturing, are set to be introduced, as stated by the Ministry of Commerce & Industry.

The Ministry emphasized that the WPI will be available for five years post-release, allowing users ample time to transition to the Producer Price Index (PPI). The item basket for the WPI series has expanded from 697 to 957 items, with crude petroleum and natural gas now categorized under the fuel and power group to enhance the tracking of energy prices. Users are advised to exercise caution when making historical comparisons due to significant changes in the item basket.
