Key points

  • India's wholesale price index rose 9.92% year over year in August, up from 9.78% in July and slightly above economists' expectations.
  • Fuel and power prices increased 22.93%, while the food index rose 7.05% and manufactured-product prices climbed 8.37%.
  • The figures are provisional and measure producer-level prices, so any impact on consumer inflation will depend on how businesses absorb or pass through costs.

India's wholesale inflation accelerated in August as energy and food costs rose, adding pressure on manufacturers, distributors and businesses already navigating expensive inputs. The government's provisional Wholesale Price Index increased 9.92% from a year earlier, compared with 9.78% in July. The result was marginally above the 9.89% average forecast in a Reuters poll.

Fuel remains the strongest pressure point

Fuel and power prices climbed 22.93% from August 2025, accelerating from 20.05% in July, according to the Office of the Economic Adviser. Within that group, crude petroleum and natural gas prices rose 34.41% year over year, while mineral-oil prices increased 38.48%. The government identified mineral oils as one of the largest drivers of the overall increase.

That matters well beyond the energy sector. Higher fuel costs can raise freight, electricity and production expenses across supply chains. Companies with limited pricing power may have to absorb part of the increase through narrower margins, while others may seek to pass costs to customers. The timing and scale of that pass-through remain uncertain and vary by industry.

Food and factory-gate prices also rise

The WPI food index, which combines primary food articles and manufactured food products, recorded annual inflation of 7.05%, up from 6.65% in July. Manufactured-product inflation edged up to 8.37% from 8.29%. The official release also listed food articles, processed food, basic metals, non-food articles and chemical products among August's major drivers.

The all-commodities index rose to 110.8 from 110.0 in July on the new 2022-23 base. Primary articles increased 7.76% year over year, although that rate slowed from 8.52% a month earlier. The mix shows that inflation was not uniform: some raw-material pressures eased, but energy and several manufactured categories continued to accelerate.

Wholesale and consumer inflation tell different stories

A separate government release showed India's consumer inflation at 4.82% in August, up from 4.45% in July. The two measures should not be treated as interchangeable. WPI tracks prices at the wholesale and producer level, while consumer inflation reflects the basket households buy. Wholesale costs can feed into retail prices, but taxes, contracts, inventories, margins and demand affect how quickly that happens.

For policymakers, the combination of rising consumer inflation and strong wholesale cost pressure complicates the outlook. For businesses, the immediate issue is whether energy, food and materials remain expensive long enough to alter procurement, production or pricing plans. Importers and transport-intensive sectors face particular exposure when global fuel costs rise, but the index alone does not establish how individual companies will respond. Banks and bond markets may also watch for evidence that producer costs are becoming embedded, because persistent inflation can influence expectations for interest rates and credit conditions.

Provisional data leave room for revision

The August WPI estimate was compiled with an 84.4% weighted response rate and remains provisional. The same release revised June's annual wholesale inflation to 9.97% from an earlier estimate of 9.87%. That revision is a reminder that the headline can change as more responses arrive. September's wholesale and producer-price estimates are scheduled for October 14, when officials will have another reading on whether the current pressure is broadening or beginning to ease.
