In March, India’s WPI inflation surged to a 38-month high as the economy was impacted by rising energy costs and manufacturing costs. The Wholesale Price Index (WPI) inflation rate increased to 3.88 percent on Wednesday, nearly doubling from 2.13 percent in February 2026, according to preliminary data released by the Ministry of Commerce and Industry. This is the first time wholesale inflation in India has reached this level since January 2023. After rising geopolitical tensions in West Asia, the rise was primarily driven by a sharp increase in crude petroleum, natural gas, and basic metals.
Energy Prices Push WPI Inflation Higher
The Fuel and Power sector was primarily responsible for the rise in WPI inflation in March 2026. In February, this segment experienced deflation, with a value of -3.78 percent. In March, however, its value increased to 1.05 percent. Crude petroleum and natural gas both experienced a significant month-over-month increase of 36.16 percent within this category. This demonstrates how domestic inflation is directly affected by global energy prices. Crude oil prices have skyrocketed all over the world, reaching $120 per barrel earlier this month. This rise is mainly due to supply disruptions and ongoing geopolitical issues in major oil-producing regions.
On March 26, the Indian government reduced excise taxes on gasoline and diesel by 10 per liter to provide some relief. However, the wholesale price index inflation still clearly reflects the impact of high energy costs despite this step.
Breakdown of Wholesale Inflation Across Sectors
The rise in wholesale inflation in India was not limited to one sector. It was seen across multiple categories.
Primary Articles Inflation Increases
Inflation in primary articles rose to 6.36% in March, compared to 3.27% in February.
Although food prices showed some improvement, the sharp increase in minerals and crude oil pushed the overall index higher.
Manufactured Products See Rising Costs
Manufactured products, which make up more than 64% of the WPI, also saw inflation increase to 3.39%.
Prices rose in 16 out of 22 industry groups, including:
- Basic metals
- Textiles
- Chemicals
This increase shows that production costs at the factory level are rising, which may impact final product prices in the future.
WPI Food Index Offers Some Relief
There was some good news in the WPI food index, which remained stable at 1.85%.
Vegetable prices dropped significantly:
- Onion prices fell by 42.11%
- Potato prices declined by 27.94% (year-on-year)
This helped control the overall wholesale inflation rate and prevented it from rising even more.
What Rising WPI Inflation Means for the Economy
The increase in WPI inflation is an important signal for the economy. While the Reserve Bank of India (RBI) mainly focuses on the Consumer Price Index (CPI), which stood at 3.4% in March, WPI is often seen as an early indicator of future inflation.
If wholesale prices remain high, companies may pass these costs to consumers. Retail inflation may rise as a result in the coming months. The RBI may need to be cautious when cutting interest rates as a result of this. Controlling inflation may take precedence over encouraging growth. India’s economy is increasingly being affected by rising global energy prices and supply-related issues, as evidenced by the 38-month high of WPI inflation in March 2026. While stable food prices have provided some relief, rising costs in fuel and manufacturing remain a concern.
Going forward, trends in crude oil prices and global developments will play a major role in deciding the direction of wholesale inflation in India.
