India WPI inflation jumps to 11.39% in September, fuel prices lead surge
Synopsis
India's wholesale inflation surged to 11.39 per cent in September 2026 — the steepest reading in recent months — with crude petroleum and natural gas prices jumping 57.32 per cent year-on-year and mineral oils up 40.02 per cent. The broad-based rise across fuel, food, and manufactured goods signals deepening factory-gate pressures that could test the RBI's inflation management calculus in the months ahead.

The final WPI for July 2026 was confirmed unchanged at 9.78 per cent .
Next data release: WPI, Output PPI, and Input PPI for October 2026 on 16 November 2026 .
India's wholesale price inflation (WPI) accelerated to 11.39 per cent in September 2026, up sharply from 9.92 per cent in August, driven by steep rises in fuel, crude petroleum, food articles, and several manufactured products, according to provisional data released by the Ministry of Commerce and Industry on Wednesday, 14 October. The latest reading marks a notable jump in factory-gate price pressures and is likely to keep policymakers alert ahead of the next monetary policy review.
Key Numbers at a Glance
The Wholesale Price Index (WPI) for all commodities rose to 112.5 in September from 110.8 in August, reflecting broad-based price hardening across categories. Separately, the Output Producer Price Index (PPI) for all commodities also moved to 112.5 from 110.8 in August, mirroring the WPI movement. The trial Input Producer Price Index (IPPI) for the manufacturing sector increased to 106.1 in September from 104.2 in August, signalling rising input cost pressures for manufacturers.
Fuel and Power Inflation Leads the Charge
Inflation in the fuel and power basket climbed to 25.85 per cent in September from 22.93 per cent in August — the single largest sectoral contributor to the overall print. Within this basket, mineral oils recorded inflation of 40.02 per cent, while crude petroleum and natural gas posted a year-on-year surge of 57.32 per cent. Fuel and power prices overall moved to an index level of 110.5 in September from 108.3 in August.
Food and Manufactured Products Also Under Pressure
Inflation in primary articles rose to 8.67 per cent from 7.76 per cent a month earlier, while the WPI Food Index recorded annual inflation of 8.66 per cent in September compared with 7.05 per cent in August — a significant sequential acceleration. Manufactured products, which carry the highest weight in the WPI basket, registered inflation of 9.76 per cent. The ministry identified mineral oils, food articles, crude petroleum and natural gas, coal and lignite, basic metals, chemicals and chemical products, textiles, rubber and plastic products, and electrical equipment as the major contributors to the September print.
July Final Data Confirmed Unchanged
The government confirmed that the final WPI for July 2026 remained unchanged at an index level of 110.0, with annual inflation also confirmed at 9.78 per cent. The final July index was compiled with a weighted response rate of 98.97 per cent, while the provisional September index carries a weighted response rate of 83.4 per cent — standard for a first-release estimate.
What Comes Next
The government is scheduled to release WPI, Output PPI, and trial Input PPI data for October 2026 on 16 November 2026. A sustained WPI elevation at over 11 per cent will feed into debates around producer margins, retail pass-through, and the Reserve Bank of India's rate trajectory — particularly as the gap between wholesale and retail inflation remains a closely watched signal for inflation transmission across the supply chain.
Point of View
Two categories with limited short-term policy levers. The 57 per cent year-on-year jump in crude petroleum and natural gas prices is particularly telling: it suggests that global energy price transmission into the domestic wholesale chain is intensifying, even as the retail CPI narrative has been relatively contained. The divergence between WPI and CPI bears watching — historically, a wide WPI-CPI gap eventually compresses through either retail pass-through or margin erosion at the producer level, neither of which is benign for consumers or for corporate earnings. With the RBI balancing growth support against inflation vigilance, a persistently elevated WPI complicates the case for rate easing in the near term.

What is India's WPI inflation for September 2026?
India's wholesale price inflation (WPI) stood at 11.39 per cent in September 2026, up from 9.92 per cent in August, according to provisional data released by the Ministry of Commerce and Industry on 14 October 2026. The rise was driven primarily by fuel, crude petroleum, food articles, and manufactured products.
Why did WPI inflation rise so sharply in September 2026?
The acceleration was driven by a broad-based rise in prices across key categories. Fuel and power inflation jumped to 25.85 per cent, with crude petroleum and natural gas alone up 57.32 per cent year-on-year, while food inflation also climbed to 8.66 per cent and manufactured products registered 9.76 per cent inflation.
What is the WPI Food Index inflation for September 2026?
The WPI Food Index recorded annual inflation of 8.66 per cent in September 2026, a significant jump from 7.05 per cent in August. Food articles were among the major contributors to the overall wholesale inflation print cited by the Ministry of Commerce and Industry.
When will India's October 2026 WPI data be released?
The government will release WPI, Output Producer Price Index (PPI), and trial Input PPI data for October 2026 on 16 November 2026.
What does a high WPI mean for consumers and the economy?
A high WPI indicates rising costs at the producer and wholesale level, which can eventually pass through to retail prices, squeezing consumer budgets. It also signals input cost pressures for manufacturers and may influence the Reserve Bank of India's decisions on interest rates and monetary policy stance.
