September inflation seen jumping to 5.4-5.6%, above RBI target, polls show

India's retail inflation is expected to have climbed above 5% in September 2026, according to two economist polls published ahead of the official data, which the government is due to release on Monday, October 12, 2026. A Reuters poll of 41 economists, conducted from October 5 to 7 and reported on October 8, put the median forecast at 5.40% for September, up from 4.82% in August, with forecasts ranging from 4.90% to 5.90%. A separate Mint poll of 19 economists forecast 5.6%, which would be the highest reading in 23 months. Economists said costlier food and energy were the main drivers. The polls follow the Reserve Bank of India's decision on October 7 to raise its policy repo rate.

Retail inflation measures how fast prices are rising for the things households buy, from vegetables and cooking oil to rent, fuel and school fees. A jump from below 5% to around 5.5% in a single month would mean noticeably faster price increases for families, and it would come just as the festive season pushes up spending.

The numbers also explain the RBI's recent turn. On October 7, the central bank raised its repo rate and moved to a tightening stance, saying the inflation outlook was no longer as benign as it had been a year earlier. If the September figure comes in near the poll forecasts, it will support the RBI's view and keep the door open for further action. A reading at the top of the range, close to 6%, would increase pressure for another rate increase; one at the lower end would ease it.

Energy is a key concern. High global oil prices linked to tensions in West Asia raise the cost of transport and of goods that need fuel to make and move. Economists say these costs are now spreading more widely through the economy, which is harder for the central bank to ignore than a short-lived spike in vegetable prices.

For businesses, persistent inflation means higher input costs and possibly higher borrowing costs. For savers, it means the real return on bank deposits is shrinking. For borrowers with floating-rate home or business loans, rate increases by the RBI can feed through to higher EMIs over time.

Short-term: Markets will react to the October 12 print. A higher-than-expected figure could push up bond yields and weigh on rate-sensitive stocks such as banks, real estate and autos.

Long-term: If inflation stays above 5% into the winter, as the RBI projects, interest rates are likely to stay higher for longer, raising borrowing costs for households and businesses.

Who is affected: Households facing higher prices for food and fuel, borrowers with floating-rate loans, savers holding fixed deposits, businesses with rising input costs, and investors in bonds and equities.
