India’s wholesale inflation accelerated to 11.39% in September 2026, marking a sharp increase from 9.92% in August as prices rose across fuel, food and manufactured products.
The provisional figures released by the Ministry of Commerce and Industry on October 14 show that wholesale price pressures strengthened across the economy. The overall Wholesale Price Index (WPI) reached 112.5 in September, compared with 110.8 in August, under the current base-year series of 2022–23.

Impact: Higher wholesale prices may increase input-cost pressure for manufacturers, transport-related businesses and other producers, although the effect on retail prices will depend on market conditions and cost pass-through.
The September inflation rate was higher than the August reading and indicates that price pressures at the wholesale level remain significant. The increase also matters for businesses because higher costs for energy, raw materials and intermediate goods can affect production expenses, distribution costs and pricing decisions.
However, WPI inflation should not be confused with retail inflation. Wholesale inflation measures changes in prices at an earlier stage of the supply chain, while retail inflation tracks prices paid by consumers. Changes in wholesale prices may eventually influence retail prices, but the extent and timing depend on factors such as transport costs, competition, taxes, demand and businesses’ ability to absorb higher expenses.
Fuel and power emerge as a major source of pressure
Editorial Analysis
Why This Matters
Wholesale inflation affects the cost environment in which businesses operate. When energy, food-related commodities and manufactured inputs become more expensive, companies may face pressure on margins, procurement budgets and production costs. The September figures are notable because inflation increased across several major WPI categories. The rise in fuel and power costs is particularly relevant to energy-intensive industries, while the increase in manufactured-product inflation may affect businesses that rely on industrial materials. For households, the key question is whether these pressures translate into higher retail prices. That outcome cannot be inferred from WPI alone, so retail inflation data and category-specific price movements must also be monitored.
Fuel and power inflation increased to 25.85% in September, compared with 22.93% in August. The category recorded one of the strongest annual price increases among the major WPI groups.
Within this category, crude petroleum and natural gas prices rose 57.32% year-on-year, compared with 34.41% in August. Mineral oils recorded inflation of 40.02%, while coal and lignite inflation increased to 9.31%.
These changes are important because energy is a key input for transportation, manufacturing, logistics and several other economic activities. Higher energy-related costs can affect companies directly through fuel expenses and indirectly through the prices of materials and services they purchase.
The impact on consumers, however, is not automatic. The relationship between wholesale energy prices and retail fuel or electricity bills depends on pricing arrangements, taxes, regulation and the extent to which suppliers pass higher costs on to customers.
Manufactured-product inflation rises to 9.76%
Inflation in manufactured products increased to 9.76% in September, up from 8.37% in August.
The manufacturing category carries a substantial weight in the wholesale price index, making changes within this group important for the overall reading. The government identified products and industries including basic metals, chemicals, textiles, rubber and plastic products, and electrical equipment among the contributors to wholesale inflation during the month.
Higher prices for industrial inputs can create pressure across production chains. For example, manufacturers that purchase metals, chemicals or plastic components may face increased costs for the materials needed to produce finished goods.
Businesses may respond in different ways. Some could absorb part of the increase by accepting lower margins, while others may adjust selling prices if market conditions permit. The final impact depends on the sector, the level of competition, demand and the availability of alternative suppliers.
The September figures therefore warrant attention not only from policymakers but also from manufacturers and businesses assessing their operating costs.
Wholesale food inflation accelerates
The WPI Food Index recorded annual inflation of 8.66% in September, compared with 7.05% in August.
This index combines food articles in the primary-articles group with manufactured food products. It is therefore broader than a measure covering only fresh food sold in wholesale markets.
The increase suggests stronger wholesale price pressure across the food-related categories included in the index. The government identified food articles and manufactured food products among the contributors to the overall inflation picture.
Food prices are particularly important because changes can affect household budgets as well as businesses involved in food processing, storage, transport and distribution. However, the WPI food index does not tell consumers exactly how much the price of a particular vegetable, cereal or packaged food item has changed at a retail shop.
Retail prices can move differently depending on local supply, seasonal availability, transport expenses, retailer margins and the time taken for wholesale changes to pass through the supply chain.
Primary-article inflation also moves higher
Inflation in primary articles rose to 8.67% in September from 7.76% in August. This category includes several commodities supplied at an early stage of production, including food articles, non-food articles and minerals.
The rise indicates that price pressure was not limited to energy and manufactured goods. It also extended to the primary-article group, which can affect costs for businesses that depend on agricultural, mineral and other basic inputs.
The movement across multiple major categories is important because it suggests a broader increase in wholesale price pressures rather than a change concentrated in only one group.
What does the 11.39% figure actually mean?
The September WPI inflation rate measures the percentage change in the wholesale price index compared with September 2025. It does not mean that every product became 11.39% more expensive, nor does it mean that every household will face an equivalent increase in living costs.
Different product groups recorded different inflation rates. Fuel and power inflation reached 25.85%, manufactured-product inflation stood at 9.76%, and primary-article inflation was 8.67%.
The overall figure combines the movement of different categories according to their respective weights in the index.
The data also remains provisional. The government’s release notes that the September index was compiled using a weighted response rate of 83.4%. The figures may be subject to revision as additional information becomes available.
What could the data mean for the economy?
Persistently high wholesale inflation can complicate planning for businesses because it makes input costs less predictable. Companies may need to reassess procurement budgets, production expenses, inventory management and the prices they charge customers.
The effect on households will depend on whether higher costs are passed through to retail markets. Some businesses may absorb part of the increase, while others may raise prices. The outcome can differ significantly across sectors.
For policymakers, the figures provide another indicator of price pressures within the economy. Wholesale inflation is not the same as the consumer inflation measure used for the Reserve Bank of India’s inflation-targeting framework, but it can offer information about cost developments earlier in the supply chain.
The next monthly release will help show whether September’s increase persists, moderates or changes direction. Until further data becomes available, the September figures should be treated as evidence of rising wholesale price pressure—not as proof that every consumer price will increase at the same rate.
