New Delhi, Oct 13 (PTI) Retail inflation slowed to an over 8-year low of 1.54 per cent in September and slipped below Reserve Bank's comfort zone mainly due to subdued prices of vegetables, fruits and pulses, showed government data released on Monday.

The consumer price index (CPI) based inflation was 2.07 per cent in August and 5.49 per cent in September 2024. The previous low was 1.46 per cent in June 2017.

It is for the second time that retail inflation has slipped below 2 per cent in 2025. The government has mandated the RBI to ensure CPI remains at 4 per cent with a margin of 2 per cent on the either side.

"There is decrease of 53 basis points in headline inflation of September, 2025 in comparison to August 2025. It is the lowest year-on-year inflation after June 2017," the National Statistics Office (NSO) said.

Year-on-year food inflation during September 2025 was (-) 2.28 per cent compared to (-) 0.64 per cent in August and 9.24 per cent in September last year.

"The decline in headline inflation and food inflation during the month of September 2025 is mainly attributed to favourable base effect and decline in inflation of vegetables, oil and fats, fruits, pulses and products, cereal and products, egg, fuel and light," NSO said.

According to the NSO data, inflation in rural India was at 1.07 per cent and in urban parts at 2.04 per cent.

Highest inflation was in Kerala at 9.05 per cent and lowest in Uttar Pradesh (-) 0.61 per cent.

In its October bimonthly monetary policy, the Reserve Bank lowered its inflation projection for 2025-26 to 2.6 per cent from 3.1 per cent estimated in August.

Regarding the inflation outlook for second half of the fiscal, RBI said that healthy progress of the south-west monsoon, higher kharif sowing, adequate reservoir levels and comfortable buffer stock of foodgrains should keep food prices benign.

It said that the recently implemented GST rate rationalisation would lead to a reduction in prices of several items in the CPI basket. Overall, the inflation outcome is likely to be softer than what was projected in the August MPC resolution, primarily on account of the GST rate cuts and benign food prices.

Commenting on the data, Aditi Nayar, Chief Economist, ICRA said the CPI inflation eased to a 99-month low in September 2025, pulled down by sharper-than-anticipated disinflation in food and beverages to 1.4 per cent (an 81-month low), despite several other categories recording a sequential uptick in year-on-year inflation prints.

"We expect the CPI inflation to average 2.6 per cent in FY26, dampened by the GST rationalisation as well as the continued benign food prices. ICRA believes that a final 25 bps rate cut is possible in December 2025 with its timing contingent on the degree of further transmission of the cumulative 100 bps rate cuts to the credit market, as well as the growth implications of the GST rejig and tariffs," Nayar said.

Earlier this month, Reserve Bank of India expectedly left its key interest rates unchanged as it waited for greater clarity on the impact of US tariffs as well as playout of earlier rate cuts and recent tax reductions.

Paras Jasrai, Associate Director at India Ratings and Research said the deflationary trend in food prices has persisted into October 2025 (as of October 12, 2025), with prices of key items such as tomatoes, onions, potatoes, and pulses declining in double digits.

"Looking ahead, a favourable base effect (October 2024: 6.2 per cent) is expected to further ease retail inflation in October 2025. Additionally, the impact of GST rate rationalization will provide further support. However, much will depend on the full pass-through of the effective GST rates," he said.

Ind-Ra expects retail inflation in October 2025 to be around 1 per cent, a new low in the 2011-12 series.

"There is a scope of another round of 25bps cuts in repo rate in our view, however much would depend on the incremental data which has baked in the effective GST rates as well," Jasrai said.

According to NSO, inflation in 'fuel and light' during September was at 1.98 per cent, as against 2.32 per cent in the preceding month.

Inflation in 'transport and communication' at 1.82 per cent during September too was lower than August.

Retail inflation 1.54% in Sept 2025, pushed down by food disinflation and GST rate rationalisation. Retail CPI inflation fell to 1.54% in September 2025, driven by food disinflation and favourable base effects; recent GST rate rationalisation materially reduced prices within the CPI basket. The government's mandate that the central bank target CPI at 4% with a 2% band frames the policy response, and the Reserve Bank lowered its 2025-26 inflation projection to 2.6%, linking further rate moves to transmission of prior cuts and GST pass through.
