Wholesale inflation jumps to 11.39% in September as fuel, food and metals rise

India's wholesale price inflation rose to 11.39% in September 2026 from 9.92% in August, according to provisional data released by the Ministry of Commerce and Industry on Wednesday, October 14, 2026. The ministry said the increase was mainly due to higher prices of mineral oils, food articles, crude petroleum and natural gas, and basic metals. Fuel and power prices were up 25.85% from a year earlier, food prices rose 8.66% and manufactured products 9.76%. The figures come two days after retail inflation for September was reported at 5.54%, up from 4.83% in August.

Wholesale prices measure what businesses pay for goods before they reach shops, so they act as an early warning for the prices households will face. A jump of nearly a percentage point and a half in one month, to above 11%, shows that cost pressure is building in the pipeline. Reports link the rise to the conflict in West Asia and disruption around the Strait of Hormuz, which has pushed up global crude oil and fertiliser costs and spilled over into food and other commodities.

The gap between wholesale and retail inflation matters. With WPI above 11% and CPI at 5.54%, companies are absorbing part of their higher costs for now. That squeezes profit margins, especially for manufacturers that rely on fuel, metals and chemicals. Over time, many of them pass costs on to buyers, which is why economists watch WPI as a guide to where retail inflation could go next.

For the Reserve Bank of India, the numbers add to the case for caution. Retail inflation is already above the RBI's 4% target. Sustained increases in fuel and food costs at the wholesale level make it harder to bring retail inflation back down and reduce room for any easing of interest rates.

Short-term: Businesses face higher input costs for fuel, metals and food-based raw materials, and some are likely to raise selling prices in the festive season. Bond and currency markets will factor the data into expectations for RBI policy.

Long-term: If energy prices stay high, wholesale cost pressure could keep retail inflation above the RBI's target for longer, affecting interest rates, loan EMIs and household budgets.

Who is affected: Manufacturers and MSMEs buying fuel and raw materials, farmers paying more for inputs, households facing higher retail prices, borrowers watching interest rates, and the RBI's monetary policy committee.
