Key Commodity Group Performance
Manufactured Products (Weight 64.23%): The annual inflation for this group rose to 1.82% in December 2025, up from 1.33% in November. Notable price increases were observed in basic metals, chemicals, and textiles.
Primary Articles (Weight 22.62%): This index saw a monthly increase of 1.09%, fueled by price rises in minerals (1.62%) and non-food articles. Its annual inflation rate turned positive at 0.21% from -2.93% in the previous month.
Fuel & Power (Weight 13.15%): The index for this major group increased by 1.23% month-on-month, largely due to a rise in electricity prices, although it remained in negative territory annually at -2.31%.
WPI Food Index (Weight 24.38%): The annual rate of inflation for food items, which includes ‘Food Articles’ from the Primary Articles group and ‘Food Product’ from the Manufactured Products group, reached 0.00% in December 2025, recovering from -2.60% in November.
Data Integrity and Response Rates

What is the ‘Weighted Response Rate’ in WPI compilation? It is a statistical measure indicating the proportion of data actually received from institutional sources and manufacturing units compared to the total expected data for a given month. For December 2025, the WPI was compiled at a weighted response rate of 82.7%. This figure is typically revised upward as more data points are finalized; for instance, the final October 2025 inflation rate was based on a significantly higher weighted response rate of 93.7%.
Policy Relevance
The transition of wholesale inflation into positive territory signals a potential recovery in industrial pricing power and serve as a key indicator for recalibrating domestic monetary and trade policies.
Strategic Impact for India:
Industrial Pricing Recovery: The rise in Manufactured Products inflation indicates improved demand and potential margin expansion for Indian manufacturers after a period of cooling.
Energy Cost Monitoring: The steady monthly increases in electricity prices highlight the need for continued monitoring to ensure energy costs do not undermine industrial competitiveness.
Stabilization of Food Costs: A 0.00% Food Index inflation rate suggests a halt in the contraction of wholesale food prices, aiding the Ministry of Consumer Affairs in managing retail price expectations.
Raw Material Input Pressure: Significant increases in mineral prices (11.86% annually) and non-food articles necessitate a review of supply chain buffers to protect downstream manufacturing sectors.
