India’s retail inflation rose to 5.54% year-on-year in September 2026, from 4.83% in August, according to the National Statistics Office’s official release dated 12 October. Food inflation also accelerated, reaching 7.74% against August’s 5.97%. September readings are provisional; the August comparisons are final. The NSO release (opens in a new tab) is the controlling source.
The figures became an important macroeconomic input for the 13 October market session, alongside company earnings and oil prices. They describe a measured change in consumer prices, not an announced Reserve Bank of India policy move.
The official inflation figures

| Measure | August 2026, final | September 2026, provisional |
|---|---|---|
| All-India combined CPI inflation | 4.83% | 5.54% |
| Rural CPI inflation | 5.24% | 6.08% |
| Urban CPI inflation | 4.31% | 4.88% |
| All-India combined food inflation, CFPI | 5.97% | 7.74% |
These are year-on-year inflation rates, not monthly price increases. The current release uses the 2024=100 base-year series. A reader should not splice figures from another CPI base or an unreconciled historical series into this comparison.
The headline reading increased by 0.71 percentage points, and food inflation by 1.77 percentage points, calculated from the published rates. Percentage-point changes are not the same as percentage growth in the inflation rate.
Food prices explain an important part of the pressure
The official release records stronger food inflation in both rural and urban India. Rural CFPI inflation was 8.06% and urban CFPI inflation 7.18% in September. Those figures differ from the headline rural and urban CPI readings because food is only one part of the broader consumer basket. 1 (opens in a new tab)
Food-price pressures can squeeze household purchasing power, but the effect on individual companies is not uniform. Retailers, food processors and other consumer businesses differ in their input mix, inventory, pricing and customer base. A national inflation rate is not a direct estimate of one company’s profit margin.
Market expectations are separate from RBI decisions
Reuters’ report on the release (opens in a new tab) said the 5.54% headline figure was slightly above a 5.4% economist-poll expectation and described expectations of further policy tightening among economists. Those views are forecasts, not official commitments. This article does not present a future repo rate or rate-hike date as confirmed.
Higher inflation can influence interest-rate expectations and the discount rates used to assess financial assets. However, growth, liquidity, exchange rates and subsequent data also matter. The effect on bank shares or other rate-sensitive sectors is therefore not mechanically determined by one number.
The opening-session market update shows why the inflation release and IT earnings should be considered separately: an equity index can advance even while a macroeconomic risk remains elevated.
Currency and the next data release
Currency moves can change the rupee cost of imported goods, while oil developments can affect transport and input costs. Neither relationship establishes a guaranteed near-term effect on CPI. Our 12 October rupee closing report provides dated currency context without relabelling that prior close as today’s live exchange rate.
The NSO release says October CPI is scheduled for 12 November 2026, or the next working day if the scheduled date is a holiday. Readers should check that release and any revisions before treating the September provisional number as final. The forex overview also distinguishes dated reporting from an available executable quote.
