Factory Costs Keep Climbing as Wholesale Inflation Hits 9.92%

India’s wholesale price inflation rose to 9.92% in August as fuel and factory-made goods overpowered a cooling in primary articles. The all-commodities index stood at 110.8, up 0.8 points from 110.0 in July, on the 2022-23 base series.

The 14-basis-point rise from July’s 9.78% looks small on a headline that has sat between 9.78% and 9.97% for four months. The split is not small. Fuel and power jumped to 22.93%, manufactured products ( 63.13% of the basket) climbed to 8.37%, and primary articles eased to 7.76% from 8.52%.

Fuel Jumped Even as Farm Prices Cooled

The Commerce and Industry Ministry’s provisional wholesale price estimates for August show the pressure coming from energy and factories, not from the farm gate as a whole. Fuel and power inflation rose 2.88 percentage points from 20.05% in July, and the fuel index itself moved to 108.3 from 105.4.

Mineral oils, which carry an 8.19% weight and include petroleum products, inflated 38.48% from a year earlier after 32.40% in July. Crude petroleum and natural gas rose 34.41% after 26.99%. Coal and lignite turned positive at 1.57% after a 0.56% fall. Electricity went the other way, with prices down 1.73% after a 1.09% rise in July, so the fuel group’s heat is oil, not power tariffs.

THE AUGUST WHOLESALE SPLIT

The ministry also locked in June at 9.97%, a 10-basis-point upgrade from the first-cut 9.87%, compiled on a 99.3% weighted response. August’s first cut rests on an 84.4% response, so the print can still move. Even so, May at 9.88%, June at 9.97%, July at 9.78% and August at 9.92% leave wholesale inflation in a tight high band rather than on a one-month spike.

Manufactured Products Have Risen Every Month Since March

Factory-made goods are the large weight in WPI, and they have not paused. Inflation in manufactured products has risen in each of the six months the ministry published with this release, from 4.80% in March to 8.37% in August. The index moved to 108.8 from 108.4 in July.

That path is the delayed cost shock. Oil and fertiliser prices jumped after the West Asia war and the Hormuz blockade; chemicals, plastics, processed food and metals then repriced. A 0.08-point rise from 8.29% in July is a rounding on the month. The six-month climb is the story that will sit in company input bills.

THE MANUFACTURED INFLATION CLIMB

1. March 2026: Manufactured products inflation stands at 4.80% on the 2022-23 series.
2. April 2026: The rate jumps to 6.68% as the new fiscal year opens.
3. May 2026: Factory-gate inflation rises again, to 7.68%.
4. June 2026: The reading edges to 7.78% on the final index.
5. July 2026: Manufactured products print 8.29%.
6. August 2026: The group reaches 8.37%, the highest of those six months.

April to August wholesale inflation for all commodities averaged 9.56% this fiscal year, against a 0.20% decline in the same stretch a year earlier. Manufactured products over those five months inflated 7.78%, against 1.62% a year ago. The item-wise wholesale price series since 2023 is what lets that comparison be drawn on the new base.

Chemicals and Food Factories Are Carrying the Oil Shock

The ministry named mineral oils, food articles, manufacture of food products, manufacture of basic metals, non-food articles, and manufacture of chemicals and chemical products as the major drivers in August. Several of those groups are still running hot even where the monthly rate slowed.

Chemicals and chemical products inflated 14.30%, up from 13.12% in July, on a 6.13% weight. Manufacture of food products, 9.02% of the basket, rose to 9.65% from 8.89% and has climbed every month since March’s 2.54%. Rubber and plastic products moved to 11.18% from 10.38%. Those three sit directly on naphtha, oil and farm inputs.

Basic metals eased to 10.88% from 12.56% and electrical equipment to 11.11% from 12.34%, so not every factory line is still accelerating. Metals remain in double digits, which is why the ministry still lists them among the drivers of the level of inflation. Motor vehicles, trailers and semi-trailers rose to 3.70% from 1.80%. Textiles stayed elevated at 12.63% after 12.80%.

FACTORY-GATE INFLATION IN AUGUST

Wholesale inflation at 9.92% is more than double July’s retail inflation of 4.45%, the latest consumer-price print from the National Statistics Office. Firms that cannot pass that gap on are absorbing it in margins; those that can will show up later in the consumer index.

How the Hormuz Shock Reached Indian Wholesale Prices

The West Asia war that closed the Strait of Hormuz on February 28 pushed India’s crude import bill through a spring spike, a mid-year dip, and a fresh climb. That oil shock is now visible in mineral oils at 38.48% and in chemicals and plastics at the factory gate, which is how a shipping crisis becomes a wholesale-price print.

The Petroleum Planning and Analysis Cell says the Indian crude basket averaged $90.19 in August after $82.04 in July and $83.22 in June. April averaged $114.48 and May $106.23. September’s month-to-date average, last updated on September 10, was $104.09, and the basket was $115.98 a barrel on September 9. August was about 10% costlier than July on that official average; September has opened higher again.

THE INDIAN CRUDE BASKET

• April average: The basket printed $114.48 a barrel as the fiscal year opened on wartime freight and crude.
• July average: The official mean eased to $82.04, the lowest month in the published FY27 table.
• August average: The basket climbed to $90.19, feeding the 38.48% mineral-oils reading.
• September so far: The month-to-date mean is $104.09, with $115.98 on September 9.

April to August inflation in mineral oils was 41.65% this year against a 5.24% decline a year earlier, and crude petroleum and natural gas ran at 42.60% against a 12.55% fall. Fuel and power as a group inflated 25.20% over those five months after a 3.73% decline. The ministry’s wholesale series is catching an energy shock that eased in mid-year and then returned.

The RBI Held Rates on a 5% Retail Forecast

The Monetary Policy Committee voted on August 5 to keep the policy repo rate unchanged at 5.25% and to retain a neutral stance. The standing deposit facility stays at 5.00% and the marginal standing facility at 5.50%. The vote, under Governor Sanjay Malhotra, was unanimous.

The committee projected consumer-price inflation at 5.0% for 2026-27, with 4.7% in the July-September quarter, 5.9% in October-December, 5.5% in January-March, and 5.3% in the first quarter of 2027-28. Core inflation is put at 4.3% for the year. Real GDP growth was raised to 6.7%. Malhotra said June retail inflation had risen to 4.4% after 16 months below the 4% target, and that the first-quarter outcome still came in 30 basis points below the old forecast.

Although generalised inflation pressures continue to remain modest so far, the risks of higher food, fuel and other input prices translating into a broad-based increase in inflation persist.

Sanjay Malhotra, Governor, Reserve Bank of India, Monetary Policy Statement, August 5, 2026

The same statement said first-quarter inflation had been lower than projected because of limited pass-through of cost pressures, and that the rise was “mostly on account of fuel and food with little signs of generalisation.” August’s wholesale tables sit awkwardly against that reading. Manufactured products at 8.37%, chemicals at 14.30% and processed food at 9.65% are input prices moving through the factory, which is the channel the committee said had not yet broadened.

July consumer-price inflation was 4.45%, with food and beverages at 5.24%. The statistics office was due to publish the August retail series on September 14, the same day as the wholesale release. Economists had clustered their August retail guesses near 4.8%. Even that outcome would leave wholesale running about double the consumer rate, which is the gap companies have to close or eat.

Why the Food Index Rose While Primary Articles Fell

The WPI Food Index rose to 7.05% because manufactured food products, at 9.65%, ran hotter than farm-gate food articles at 5.67%. Primary articles as a whole eased to 7.76% only because non-food articles and minerals slowed, not because the kitchen basket cooled.

Food articles, 15.98% of the full index, ticked up from 5.44% in July. Non-food articles dropped to 14.79% from 17.66%. Minerals slowed to 8.24% from 13.28%. The primary group’s 0.76-point deceleration is those two slows doing the work, while food articles and the food-products factory line still firmed. The combined food index, weight 24.99%, moved to 118.5 from 117.1.

WHERE FOOD PRICES ACTUALLY MOVED

• Farm-gate food: Food articles inflation was 5.67% in August, up from 5.44% in July, so the field did not ease.
• Factory food: Manufacture of food products ran at 9.65%, the sixth straight monthly rise from 2.54% in March.
• Combined kitchen: The WPI Food Index printed 7.05%, up from 6.65%, pulling both layers together.
• The offset: Non-food articles at 14.79% and minerals at 8.24% slowed hard enough to pull primary articles down anyway.

The August policy statement still listed a deficient and uneven south-west monsoon and El Nino as risks to food and rural demand. Proactive supply management and grain stocks were the buffers the committee cited. Processed-food inflation at 9.65% is the part of that risk already inside the wholesale index, independent of the next harvest print.

October’s Policy Meeting Faces Costs That Have Already Spread

The next MPC meeting is scheduled for October 5 to 7. By then the committee will have August wholesale prices, the August consumer-price print, and September’s crude basket, which is already averaging $104.09 month to date and printed $115.98 on September 9. The next wholesale release, for September, is due on October 14, after that meeting has closed.

Malhotra’s August statement said there was a need for greater clarity on inflation, its path and its composition before any policy action, and that any move would also have to weigh a recalibration of rates as underlying inflation normalises from the low levels of 2025. The 125-basis-point of cuts that took the repo rate to 5.25% by December 2025 were taken when average retail inflation was much weaker. Wholesale inflation near 10% for four months, with manufactured products still climbing, is the composition he said he wanted to see more clearly.

Electricity deflation and the metals slowdown give the committee two counter-points. They do not cancel mineral oils at 38.48% or chemicals at 14.30%. The 9.92% headline will be remembered as a 14-basis-point tick. The manufactured climb from 4.80% in March to 8.37% in August is what that tick was carrying.

Rate-setters will already have sat by the time the next wholesale print lands on October 14.
