Retail Inflation Rises to 5.54% in September 2026: Food Prices Push CPI to a Near Two-Year High
India's retail inflation, measured by the Consumer Price Index (CPI), rose to 5.54% in September 2026, up from 4.83% in August. This is the highest level in 23 months, and the sixth monthly rise in a row since March.
Food prices were the main driver. Food inflation (the Consumer Food Price Index, CFPI) jumped to 7.74% from 5.97% in August. Onion prices were up about 108% compared with a year ago, while potatoes and tomatoes became cheaper.
Villages felt it more than towns. Rural inflation was 6.08% and urban inflation was 4.88%. Rural food inflation was 8.06% and urban food inflation 7.18%.
The data was released by the National Statistics Office (NSO) of the Ministry of Statistics and Programme Implementation (MoSPI), using the new CPI series with base year 2024.
A few days earlier, on October 7, 2026, the RBI's Monetary Policy Committee raised the repo rate by 25 basis points to 5.50% and projected CPI inflation of 5.2% for 2026-27.
Consumer Price Index (CPI): How India Measures Retail Inflation
The Consumer Price Index (CPI) is a number that tracks how the prices of things a normal family buys change over time. These include food, clothes, rent, fuel, transport, medicines, school fees and mobile bills. When people say "retail inflation is 5%", they mean the CPI is 5% higher than it was in the same month last year. In India, the main CPI is prepared every month by the National Statistics Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI).
The September 2026 figure of 5.54% is a CPI reading from the new 2024-base series. The jump came mostly from food, which still carries about 37% of the weight (and about 42% in villages). That is why rural inflation (6.08%) ran well above urban inflation (4.88%).
Monetary Policy Committee (MPC): How RBI Sets the Repo Rate
The Monetary Policy Committee (MPC) is a six-member committee that decides India's main interest rate, the repo rate. When it raises the repo rate, borrowing becomes costlier across the country, people and firms spend a little less, and price rise slowly cools. Its legal job is to keep CPI inflation near the 4% target while keeping growth in mind.
The MPC raised rates because inflation was climbing towards the upper end of the band. The September reading of 5.54% supports that worry, though a large part of the rise comes from food supply shocks, which interest rates cannot directly fix.
Flexible Inflation Targeting (FIT) Framework
Flexible Inflation Targeting (FIT) is the system under which the RBI's main job is to keep retail (CPI) inflation close to a number fixed by the government. In India, the target is 4%, with an acceptable band of 2% to 6%. It is "flexible" because the RBI can also keep growth in mind and need not hit 4% every single month.
At 5.54%, inflation is still inside the 2% to 6% band, but close to its upper edge. If it stays above 6% on average for three quarters, the RBI will have formally missed its target, which is why the MPC has started tightening now.
