On 12 August 2026, the Ministry of Statistics and Programme Implementation released the Consumer Price Index for July 2026 — on the new base year of 2024=100. All-India year-on-year retail inflation came in at 4.45%, with food inflation at 5.52%.
Two things make this worth a full article rather than a line in a digest. First, inflation is the one economic number that appears in the CDS/OTA General Knowledge paper, the essay and the interview alike. Second, this is a new series — the base year has changed — and base revisions are exactly the kind of technical-but-teachable subject that separates candidates who understand economics from those who have memorised a figure.
The July 2026 numbers
| Indicator (Y-o-Y, %) | Rural | Urban | Combined |
|---|---|---|---|
| CPI (General) — July 2026 | 4.84 | 3.96 | 4.45 |
| CPI (General) — June 2026 (final) | 4.74 | 3.93 | 4.38 |
| CFPI (food) — July 2026 | 5.79 | 5.05 | 5.52 |
| CFPI (food) — June 2026 (final) | 5.45 | 5.09 | 5.32 |
| Housing — July 2026 | 2.80 | 2.01 | 2.22 |
Index levels for July 2026 (base 2024=100): rural 108.34, urban 107.45, combined 107.94.
Division-wise inflation for July 2026 (combined) shows where the pressure sits:
- Food and beverages — 5.24%
- Paan, tobacco and intoxicants — 4.79%
- Clothing and footwear — 3.38%
- Furnishings, household equipment and routine maintenance — 2.40%
- Housing, water, electricity, gas and other fuels — 2.16%
And at item level, the extremes are instructive:
| Highest inflation | July 2026 | Lowest inflation | July 2026 |
|---|---|---|---|
| Silver jewellery | +109.84% | Potato | −16.56% |
| Ginger | +83.62% | Motor car and jeep | −6.72% |
| Garlic | +35.36% | Lady's finger | −5.52% |
| Gold/diamond/platinum jewellery | +32.98% | Peas | −5.27% |
| Onion | +22.54% | Tomato | −4.59% |
Note what that table teaches. Precious metals are running at extraordinary rates, while several vegetables are in outright deflation — tomato swung from +31.92% in June to −4.59% in July. Vegetable prices are volatile because supply is seasonal and perishable; a single good harvest reverses a spike. This is precisely why economists look past the headline to core inflation.
Data collection, worth knowing because it is occasionally asked: prices are gathered from 1,407 urban markets (including online markets) and 1,465 villages across all States and UTs, by field staff of the Field Operations Division of the NSO on a weekly roster. The response rate in July 2026 was 100% in both rural and urban markets. The reference date for petrol, diesel and LPG prices is the 15th of the month. CPI for August 2026 is due on 14 September 2026.
The base revision — the real story
The series has moved from base 2012=100 to base 2024=100, with the new series introduced from January 2026. The changes are structural, not cosmetic:
- Weights now come from the Household Consumption Expenditure Survey of 2023-24, replacing weights derived from the 2011-12 consumption survey.
- The number of groups has risen from 6 to 12, adopting the international COICOP 2018 classification (Classification of Individual Consumption According to Purpose) — which makes Indian data internationally comparable.
- The number of items in the basket has expanded from 299 to 358, capturing goods and services that barely existed in the household budget of 2011-12.
- The weight of food has been reduced substantially, reflecting how spending patterns have actually changed.
Why a base year must be revised. A price index measures the cost of a fixed basket over time. If the basket is frozen at 2011-12 consumption, it keeps weighting the economy of 2011-12 — heavy on cereals, light on data plans, health insurance and online services. Over a decade the index drifts away from what households actually buy, and the inflation it reports becomes the inflation of a country that no longer exists.
Why the food weight falls. This is textbook economics and worth naming in an answer: Engel's Law — as household income rises, the proportion of income spent on food falls, even though the absolute amount spent may rise. India's per-capita incomes have grown substantially since 2011-12, so food's share of the average budget has declined and its weight in the index falls accordingly.
The consequence for policy. Food is the most volatile component of the CPI. A lower food weight makes the headline index less sensitive to a bad monsoon or a tomato spike, so the headline number moves closer to the underlying trend. That changes how the same underlying economy reads on paper — and it is exactly why MoSPI cautions against mechanically comparing the new series with the old. These measurement issues sit at the centre of the CDS/OTA notes on inflation.
CPI versus WPI — the distinction that is always asked
| CPI | WPI | |
|---|---|---|
| Measures | Retail prices paid by consumers | Wholesale prices of bulk transactions |
| Coverage | Goods and services | Goods only — excludes services |
| Released by | NSO, MoSPI | Office of the Economic Adviser, DPIIT |
| Base year | 2024=100 | 2022-23 (revised from 2011-12) |
| Segments | Rural, urban and combined | Single all-India series |
| Policy role | Headline measure for monetary policy | Useful for input-cost and producer trends |
Since 2014, following the Urjit Patel Committee's recommendation, the CPI (Combined) has been the nominal anchor for monetary policy. Two related measures complete the set: the Consumer Food Price Index (CFPI), the food sub-index reported above, and the GDP deflator, the broadest measure of price change across the whole economy, derived from nominal and real GDP.
Note that both of India's main price indices have been rebased in this cycle: the CPI to 2024=100, and the WPI to 2022-23. The WPI is in fact being phased out — it now runs alongside a new Producer Price Index and is to be discontinued after a five-year parallel run. That transition, and the reason wholesale inflation currently sits far above retail inflation, are covered in our explainer on WPI at 9.78% and India's shift to a Producer Price Index.
Core inflation, and why economists insist on it
- Headline inflation is the all-items CPI — the 4.45% figure.
- Core inflation strips out food and fuel, the two most volatile and most supply-shock-driven components.
- The reason: a central bank's instrument is interest rates, which work on demand. Raising rates cannot make it rain, and it cannot lower the price of onions after a crop failure. Core inflation shows whether price pressure is broad-based and demand-driven — the kind monetary policy can actually address.
- The counter-argument, which matters in India: for a poor household, food is a very large share of spending, so core inflation understates the inflation actually experienced by those least able to bear it. A candidate who states both sides is giving a complete answer.
Useful vocabulary that examiners test: disinflation is a fall in the rate of inflation (prices still rising, more slowly); deflation is an actual fall in the price level; stagflation is high inflation with stagnant growth and high unemployment; demand-pull inflation arises from excess demand, cost-push from rising input costs.
The monetary policy framework
The link from this data release to policy runs through flexible inflation targeting, the subject of the notes on monetary policy:
- Adopted in 2016 through an amendment to the RBI Act, 1934.
- The target is 4% CPI inflation with a tolerance band of ±2%, i.e. 2% to 6%, notified by the Central Government for a five-year period.
- The Monetary Policy Committee (MPC) has six members — three from the RBI including the Governor as chairperson, and three external members appointed by the Central Government. The Governor has a casting vote in the event of a tie. The MPC meets at least four times a year.
- Failure is defined: inflation above 6% or below 2% for three consecutive quarters, on which the RBI must report to the Central Government explaining the causes, the remedial action and the expected time to return to target.
At 4.45%, July 2026 inflation sits above the 4% central target but comfortably inside the 2–6% band — the interpretation to give if asked.
Why it matters
- Inflation is the most regressive tax there is. It is not levied by anyone, but it falls hardest on those whose incomes are fixed and whose budgets are dominated by food. The 5.52% food inflation figure matters more to a landless labourer than the 4.45% headline.
- Measurement is not neutral. Changing the basket changes the number, which changes the policy response, which changes interest rates and therefore employment and investment. That is why base revisions are conducted by expert groups and published with full documentation.
- Statistical capacity is state capacity. A 100% response rate across nearly 2,900 markets and villages, every month, is a serious administrative achievement — and the credibility of monetary policy rests on it.
- The honest caveat. A new base means the series is not directly comparable with the pre-2026 numbers. Anyone comparing today's 4.45% with a figure from the 2012 series is comparing two different baskets. Saying so is the mark of a careful reader of data.
🔑 Revision block
The release. 12 August 2026 — MoSPI released the Consumer Price Index for July 2026 on the new base year 2024 = 100.
Headline numbers. Combined 4.45% (June: 4.38%) · rural 4.84% · urban 3.96%. Index levels: rural 108.34, urban 107.45, combined 107.94.
Food and other groups. CFPI (Consumer Food Price Index): combined 5.52%, rural 5.79%, urban 5.05%. Food & beverages 5.24% · clothing & footwear 3.38% · housing, water, electricity & fuels 2.16% · housing alone 2.22%.
The extremes. Highest item inflation: silver jewellery, +109.84%. Lowest: potato, −16.56%.
Data collection. Prices from 1,407 urban markets and 1,465 villages, by the Field Operations Division of the National Statistical Office, with a 100% response rate.
The new series — what actually changed. Introduced from January 2026, replacing the 2012 base. Weights drawn from the Household Consumption Expenditure Survey 2023-24. Groups raised from 6 to 12 under the COICOP 2018 classification. Basket expanded from 299 to 358 items. And the weight of food is substantially reduced — consistent with Engel's Law, that the share of income spent on food falls as income rises.
CPI vs WPI — the comparison examiners want. CPI — compiled by the NSO under MoSPI; covers goods and services; rural, urban and combined series; base 2024 = 100. WPI — released by the Office of the Economic Adviser, DPIIT (Department for Promotion of Industry and Internal Trade); covers goods only; base 2022-23 (revised from 2011-12), and being phased out in favour of a Producer Price Index.
The monetary policy frame. Combined CPI has been the anchor for monetary policy since 2014, on the recommendation of the Urjit Patel Committee. Flexible inflation targeting was adopted in 2016 through amendment of the Reserve Bank of India Act: target 4%, tolerance band ±2%, administered by a six-member Monetary Policy Committee chaired by the Governor, who holds a casting vote. Failure is defined as inflation outside the 2–6% band for three consecutive quarters.

📋 How this gets asked (PYQ pattern)
Inflation is among the most dependable CDS/OTA economy sets, with four standard framings. The agency item — CPI with NSO/MoSPI and WPI with the Office of the Economic Adviser under DPIIT, where swapping the two is the commonest error. The coverage item — that WPI excludes services while CPI includes them, almost always as a statement pair. The framework item — the 4% ±2% target, the six-member MPC, the Governor's casting vote and the three-consecutive-quarters failure rule. The concept item — headline versus core, and the disinflation/deflation/stagflation vocabulary. The fresh 2026 hook is the base revision to 2024=100 with weights from HCES 2023-24, the move from 6 to 12 groups and 299 to 358 items, plus the July headline of 4.45%. We reference the pattern, not any specific past question.
