India’s 0.25% inflation print strengthens the case for cautious RBI easing

India’s October retail inflation fell to 0.25% from a revised 1.44% in September, according to the National Statistical Office’s 12 November release. Food prices were 5.02% lower than a year earlier. The headline gives the Reserve Bank of India more room to consider easing, especially if weak demand is also restraining the prices firms can charge. The case for a cut rests on evidence about the next few quarters. October’s annual rate tells us relatively little on its own about how much households’ overall cost of living changed from September.

The comparison base did much of the work

The all-India consumer price index rose from 197.0 in September to 197.3 in October, an increase of 0.15% from the previous month. Its annual rate fell because the comparable move a year earlier was much larger. The October and September releases put the all-India index at 194.2 in September 2024 and 196.8 in October 2024. That is a rise of about 1.34% within the comparison year. These figures use the 2012-base series and the revised September 2025 index reported in November.

The arithmetic is exact in logs apart from published rounding. The change in annual log inflation equals this October’s monthly log price increase minus the corresponding monthly increase a year earlier. The first term is about 0.15 percentage point and the second about 1.33 percentage points. The difference is approximately minus 1.18 percentage points, close to the published fall of 1.19 points in the conventional annual rate. The comparison explains how the headline fell so far while the overall price level moved slightly higher in the latest month.

A high comparison base eventually drops out of the calculation. If prices continue to rise gradually, the annual rate can then increase even without a sudden acceleration at the checkout. That is why the monthly data matter. One unadjusted month can be affected by harvests, festivals and the timing of price changes, so an assessment of momentum should compare a few months and account for seasonality. It is reasonable to welcome a low headline rate while still asking whether the trend has moved as much as the annual number suggests.

Food relief matters unevenly across India

The official table shows rural headline inflation at minus 0.25% and urban inflation at 0.88%. The all-India vegetable index was about 27.6% lower than a year earlier. By contrast, the urban housing index was 2.96% higher and the combined education and health indices were 3.49% and 3.86% higher. A national average can therefore coexist with meaningful increases in expenses that some households find difficult to avoid. MoSPI, October 2025 CPI release, Tables II and III and annexures

The distributional effect also runs through income. Households that are net buyers of food gain purchasing power when food prices fall, all else equal. Farmers selling the affected crops may face lower receipts unless they make up the difference through higher volumes or lower costs. The same family can be a producer of one crop and a buyer of other food. A welfare assessment should examine rural wages, crop prices and household expenditure patterns alongside the headline CPI. The central bank’s mandate concerns aggregate inflation, while agricultural and social policy can address stresses concentrated in particular groups.

The GST cut can lower the price level once

The GST Council’s September decisions brought most of the revised rates into effect from 22 September. October was the first full month after the change. The NSO identified GST reductions as one factor behind the softer inflation reading, alongside a favourable comparison base and lower inflation in several categories. Those explanations can coexist. Identifying the contribution from the tax change requires evidence about how retail prices moved on affected products relative to suitable comparisons. Government of India, 56th GST Council recommendations · MoSPI, October 2025 CPI release, Tables II and III and annexures

For illustration, if a product’s GST rate drops from 12% to 5% and its pre-tax price stays at ₹100, its tax-inclusive price falls from ₹112 to ₹105. That is a 6.25% reduction in the price paid by the buyer under full pass-through. If the retail price falls by less, the difference could reflect changed pre-tax prices, supplier costs or margins. The example is a mechanical benchmark. To measure the reform’s effect, compare affected and unaffected items with similar pre-reform trends, and allow for changes in product size, promotions and seasonal prices.

A permanent reduction in the tax rate can provide a lasting reduction in the level of affected prices relative to the old rate. Its direct effect on the year-on-year inflation rate is temporary, because the lower price eventually appears in both the current and comparison periods. There may also be a demand effect if households spend the savings on other goods. The net implication for future inflation depends on that spending response, the breadth of the changes, and the ability of suppliers to expand output.

What would justify a cautious cut?

At its October meeting, the MPC kept the repo rate at 5.50% with a neutral stance. Its resolution already recognised softer food inflation and the expected effects of GST changes. It projected CPI inflation at 2.6% for 2025–26, rising to 4.0% in the March quarter and 4.5% in the June quarter of 2026 as base effects became less favourable. These projections preceded the October CPI release. They are a useful benchmark for deciding how much the new information changes the path the MPC expected.

The argument for a cut is that weak underlying price momentum can make the current policy rate more restrictive as expected inflation falls. If the outlook has softened while growth risks have increased, a measured cut can support borrowing and spending with less risk of reigniting inflation. The counterargument is that the striking headline owes much to food and the comparison base, while recent tax changes could support demand. A policy move based primarily on 0.25% would give too much weight to a statistic likely to change as the base rolls forward.

The relevant real interest rate is forward-looking. Subtracting the October annual CPI reading from the 5.50% repo rate gives a simple backward-looking gap of 5.25 percentage points. Subtracting the MPC’s October projection of 4.0% inflation in the March quarter instead gives an illustrative gap of 1.50 points, with the nominal rate held fixed. Neither calculation gives a precise neutral rate, and the projection is a quarterly year-on-year measure. The comparison shows how sensitive the inference is to the inflation measure used. Firms deciding whether to borrow face lending rates and expected selling prices over the life of the loan. Those are closer to the mechanism a rate decision is meant to affect.

The useful checks are the breadth of non-food price increases, services prices, wage growth and household inflation expectations, alongside output and credit indicators. Track standard core inflation and versions that separately identify unusually volatile components, using consistent definitions. The October MPC statement noted that precious metals had made a material difference to its reading of August core inflation. Reuters’ contemporaneous roundup also showed how assessments of October differed depending on which components were excluded. Changes in a narrow exclusion measure should be checked against category-level data before they determine the policy conclusion.

On the available evidence, the balance has moved in favour of cautious easing if the next set of indicators confirms that underlying inflation and demand have softened. A widespread acceleration in services prices, firmer wage growth or rising inflation expectations would weaken that case. The better monetary-policy question is whether the economy will return to the inflation target with the current rate, after the unusual food, tax and base effects have passed through.
