PRESS RELEASE OF CONSUMER PRICE INDEX ON BASE 2024=100 FOR OCTOBER, 2026

1. At a Glance

• All-India CPI (Combined) inflation for October 2026 is 6.09% (provisional). It was released on 12 Nov 2026 and is driven by food inflation (CFPI) of 8.94% [1].
• This is the first year of the rebased CPI series (base 2024=100), which replaced the 2012 base. The new series uses COICOP 2018 classification and weights from HCES 2023-24 [2].
• Why it matters: CPI-Combined is the measure behind India's 4% ± 2% inflation target. A 6.09% reading is above the 6% upper tolerance limit [1][3]. This links the release directly to RBI monetary policy and the Monetary Policy Committee (MPC).
• The release covers several examinable areas: index construction (weights, base year, divisions), the gap between food and headline inflation, the rural–urban gap, and how MoSPI and NSO collect data [1][2].

2. Why in the News

• 12 Nov 2026: MoSPI released CPI data for October 2026. Headline inflation was 6.09%, rural 6.63%, urban 5.41% and CFPI 8.94% [1].
• Inflation has risen every month from Jan-26 (2.74%) to Oct-26 (6.09%) [1]. That is a move from near the bottom of the tolerance band to above its top within one year.
• Onion inflation of 116.22% (item weight 0.7006) was the highest among key items. Inflation in the Restaurants & accommodation services division was 10.06% [1].
• Policy context: the Government has kept the 4% CPI target with a 2–6% band for 1 Apr 2026 – 31 Mar 2031, via a Gazette notification dated 25 Mar 2026 [3].

3. Background & Evolution

• Earlier base: CPI used 2012=100 until the new series replaced it [2].
• Aug 2025: RBI released a discussion paper reviewing the Flexible Inflation Targeting (FIT) framework. It asked whether the tolerance band should be reduced, increased or eliminated [4].
• 12 Feb 2026: the first CPI print on base 2024=100 came out, for January 2026: 2.75% (provisional) [2].
• Weights come from the Mixed Modified Reference Period (MMRP) results of the Household Consumption Expenditure Survey (HCES) 2023-24 [2].
• The basket has 358 weighted items in 12 divisions, 43 groups, 62 classes and 192 sub-classes, under COICOP 2018 [2].

• All-India back-series (rural, urban, combined) from January 2013 onward was released with the first data, along with linking factors to join the old and new series [2].

• 25 Mar 2026: the FIT target (4% ± 2%) was renewed for FY2026-27 to FY2030-31 [3].

• Background facts (not cited here; verify independently): FIT began in 2016 under the amended RBI Act, 1934 (Sec. 45ZA). The 4% ± 2% target was kept in the 2021 review.

4. Core Static Facts

Key terms [1]:

• Year-on-year (Y-o-Y) inflation: the index for a month compared with the same month a year earlier. This removes seasonal effects.
• Month-on-month (M-o-M) change: compares consecutive months. It shows momentum.
• Index vs rate: the index is a level (110.05). Inflation is the percentage change in that level.
• Division vs group: a division is the broader class (01 Food & beverages). A group sits inside it (01.1 Food).

5. Multi-Dimensional Analysis

Economic / Monetary

• Headline inflation of 6.09% is above the 6% upper limit [1][3]. If it stays there, the MPC comes under pressure to tighten or delay easing.
• Food inflation (8.94%) is well above headline (6.09%), so food is pulling headline up [1]. These are mostly supply-side shocks (vegetables such as onion at 116.22%), which interest rates do little to fix.
• Services inflation is also high: Restaurants & accommodation at 10.06% [1]. This suggests price pressure is spreading beyond food, which matters for the core-inflation debate.
• Base effect: 2025 index values were fairly flat [1]. Any rise in 2026 prices therefore shows up fully in the Y-o-Y rate, which explains the steady climb from 2.74% to 6.09%.

Social / Equity

• Rural inflation (6.63%) is higher than urban (5.41%), and the gap has widened from September (6.08% vs 4.88%) [1].
• A likely reason is that food takes a bigger share of rural household spending. The release itself does not say this [1].
• Food inflation acts like a regressive tax. It hits poorer households hardest, because they spend a larger share of their budget on food.

Statistical / Technological

• The 2024 base updates the basket using spending patterns from HCES 2023-24 [2]. The basket includes online markets [1], so it reflects how people now shop.
• COICOP 2018 makes Indian CPI comparable with other countries' CPIs [2].
• Back-series to 2013 and linking factors keep the long-run series continuous for research and policy work [2].

Governance / Administrative

• MoSPI publishes on a fixed date (the 12th of each month), achieved a 100% response rate, and hosts open data on eSankhyiki [1]. All three support statistical credibility.
• MoSPI itself warns that some State-level item indices are built from thin samples and should be used with caution [1]. This limits how far States can use them for fine-grained policy.
• The RBI's 2025 discussion paper raises the question of how a rebased index should feed into the inflation target [4].

Weights and their effect on headline

• An item's weight limits how much it can move the headline [1]. Onion has a weight of 0.70 even at 116% inflation, while the food division weighs 36.75.
• Silver jewellery and garlic also show extreme inflation but have small weights, so they move the headline less [1].

6. Recent Developments (last 12–18 months)

• Aug 2025: RBI released a discussion paper on reviewing the FIT framework [4].
• 12 Feb 2026: the base-2024 CPI series launched. January 2026 inflation was 2.75% (provisional) [2].
• 25 Mar 2026: the Gazette notification kept 4% ± 2% for 2026–31 [3].
• Jan → Oct 2026: headline CPI rose every month, from 2.74% to 6.09% [1].
• Sep 2026 (final): rural 6.08%, urban 4.88% [1].
• 12 Nov 2026: the October 2026 release (6.09% headline, 8.94% CFPI) [1].

7. Prelims Hooks

• CPI is compiled by the NSO under MoSPI, not by RBI and not by DPIIT [1].
• The current CPI base year is 2024=100. The previous base was 2012 [2].
• CPI weights come from HCES 2023-24, using the MMRP results [2].
• The new CPI basket has 358 items in 12 divisions [2].
• CPI 2024 uses COICOP 2018 classification [2].
• The first CPI release on base 2024 was on 12 Feb 2026, for January 2026 [2].
• Prices are collected weekly by NSO's Field Operations Division [1].
• Price coverage is 1,407 urban markets (including online) and 1,465 villages [1].
• Food & beverages division weight is 36.75. CFPI weight is 34.78 [1].
• October 2026: headline 6.09%, CFPI 8.94%, rural 6.63%, urban 5.41% [1].
• The highest-inflation key item in October 2026 was onion (116.22%) [1].
• State- and item-wise CPI data is on MoSPI's eSankhyiki portal [1].
• The FIT target of 4% (2–6%) is notified for 1 Apr 2026 – 31 Mar 2031 [3].

8. Why 6.09% on the New Basket Means More Than It Seems

• Food now carries less weight in the index
• In the 2012 series, food and beverages had a weight of about 45.86. In the 2024 series it is 36.75 [5].
• So the same onion or vegetable shock now moves the headline number less than it used to.

• If headline still crosses 6%, more of the push must be coming from outside food.

• A rough split of October's 6.09%

• CFPI (the Consumer Food Price Index, which tracks food prices only) has a weight of 34.78 and rose 8.94% [1]. Multiplied out, food adds roughly 3 percentage points.
• That leaves about 3 points for the other ~65% of the basket. This means non-food prices are rising at roughly 4.5%, which is above the 4% target.

• This is only an estimate. Each item's real share changes as its price moves, so treat it as a direction, not an exact figure.

• More of the basket is services now

• Weighted items rose from 299 to 358. Services went from 40 to 50 items [7].

• Restaurants at 10.06% [1] now matter more to the headline than they did in the old basket.

• Housing is measured differently

• Rural house rent is now part of the index. Housing is built from three parts: rent, repair and maintenance, and water and other dwelling services [7].

• MoSPI has also proposed further changes to how the housing index is compiled [11]. Housing numbers may shift again, so be careful comparing them across years.

• What this means for the target

• The 4% ± 2% band was retained in March 2026 [3], but it was first designed in a period when food was about 46% of the basket [8].
• A 6% reading on a basket with less food is a stronger warning than a 6% reading on the old one.

9. What the Index Does Not Count: Free Ration Grain

• Free PDS grain gets zero weight
• PDS is the Public Distribution System, through which the government gives subsidised or free grain.
• MoSPI leaves free PDS items out of CPI because households spend no money on them [6].

• MoSPI says this follows the IMF's CPI manual: CPI should price only what households actually pay for [7].

• Why this matters for the poor

• CPI tells us how market prices are changing. It does not tell us the cost of living for a family that gets most of its rice or wheat free.
• For such a family, a rise in market cereal prices hurts less than the index suggests.

• But they still buy onions, pulses and oil at market prices. Those are exactly the items driving October's food inflation [1].

• MoSPI itself treated this as an open question

• It released two separate discussion papers on free PDS items, on 23 Dec 2024 and 4 Oct 2025, before deciding [6].
• In a Mains answer, treat it as a deliberate choice of method, not a settled fact. CPI measures prices, not welfare.

10. Should RBI Ignore Food Prices? The Case For and Against

• The strongest case for ignoring food
• Food inflation in India comes mostly from supply shocks, such as a bad monsoon or a crop failure. A higher repo rate cannot grow more onions.
• Food prices are also more volatile than core inflation (the price rise left after removing food and fuel) [8].

• So, the argument goes, the MPC should target core inflation and look past food spikes.

• What this argument gets right

• Rate hikes do little about a 116% onion spike [1]. Making borrowing costlier for everyone to fight one crop's shortage has a real cost to growth.

• Why RBI has not accepted it

• Food price rises spread to other prices. RBI research found that food price rises spill over into non-food items [9]. When food costs more, workers ask for higher wages and restaurants raise their prices.
• Headline moves towards core, not the other way. A May 2026 RBI Bulletin article found that headline inflation comes back towards core over time, not the other way round [10]. This supports using core as a guide while still targeting headline.
• Almost every inflation-targeting country uses headline. Of 48 countries that target inflation, 47 target headline. Only Uganda targets core [4].

• People judge inflation by what they pay at the shop. If RBI ignored food, people would stop believing its inflation promise, because food is what they buy every day.

• The honest balance

• Ignoring a one-time food shock is sensible. But October's print shows restaurants at 10.06% [1] and non-food prices above 4%. RBI can no longer say "this price rise will pass on its own."

11. What MoSPI and RBI Should Do Next

• MoSPI should finish the housing methodology review and publish how much it changes the series
• A housing discussion paper is pending [11]. Rural rent has just entered the index [7].

• If the method changes again without a clear note on the impact, users cannot tell a real price change from a change in method.

• MoSPI should make the free-PDS choice easy to check

• Two discussion papers show the treatment was contested [6].

• Publishing an additional index that values free grain would let researchers and States see the living cost for ration-card households, without changing the official CPI.

• The MPC should explain the food-to-core spillover in its decisions

• RBI's own research shows spillovers from food to non-food prices [9], and that headline moves towards core [10].

• When the MPC acts on a food-led rise, it should say which spillover it is responding to, for example the 10.06% restaurant inflation [1]. This shows the public it is reacting to spreading prices, not just to onions.

• Students should read the next prints against momentum, not only Y-o-Y

• A flat 2025 base pushed the Y-o-Y rate up all through 2026 [1].
• When that base effect ends, Y-o-Y may fall even if prices keep rising. Watch the M-o-M change to see real momentum.

12. Anchors for Answers

• Data: Food and beverages weight cut from about 45.86 (2012 series) to 36.75 (2024 series), so food shocks now move headline less [5]
• Data: Basket grew from 299 to 358 weighted items. Services rose from 40 to 50 [7]
• Data: 47 of 48 inflation-targeting countries target headline, not core [4]
• Report/Committee: RBI, Review of Monetary Policy Framework: A Discussion Paper (Aug 2025) [4]. RBI Bulletin, Food Prices the 'True' Core of India's Inflation (Jan 2024) [8]. RBI Bulletin, Are Food Prices Spilling Over? (Aug 2024) [9]
• Report/Committee: MoSPI Discussion Paper 2.0 on Treatment of Free PDS Items (Oct 2025): free social transfers excluded from CPI [6]
• Law/Case: RBI Act, 1934, Sec. 45ZA. Under it, the Government notified the 4% ± 2% target for 2026–31 [3]
• Comparison: Uganda is the only inflation-targeting country that targets core inflation rather than headline [4]
• Scheme: Public Distribution System (free grain). Its items carry zero weight in CPI, so CPI does not show the cost of living for ration-card households [6]

13. Mains Relevance

• GS-III: Indian Economy, covering mobilisation of resources, growth, inflation, monetary policy and food security (food inflation, supply chains).
• GS-II (minor link): Government policies and interventions, and the institutional credibility of statistical bodies.
• Possible question stems: 1. Food inflation in India is primarily a supply-side phenomenon, limiting the efficacy of monetary policy. Critically examine in the context of recent CPI trends. (250 words) 2. Discuss the significance of rebasing the Consumer Price Index to 2024. How does revision of weights and classification improve the measurement of inflation? (150 words) 3. Persistent rural–urban divergence in retail inflation has distributional consequences. Analyse its causes and suggest policy responses. (250 words)

14. Related Topics to Study Next

• Flexible Inflation Targeting and the MPC: CPI-Combined is the target variable; the 2026–31 renewal [3].
• WPI and the proposed PPI: wholesale vs retail measurement, and the base-revision debate.
• HCES 2023-24: the source of the CPI weights; also used for poverty and consumption estimates [2].
• GDP base revision and the National Accounts: part of the same MoSPI rebasing drive.
• Core inflation and headline inflation: the services inflation story (Restaurants division at 10.06%) [1].
• Food supply-chain policy: TOP (Tomato-Onion-Potato) scheme, buffer stocks, export curbs. Relevant to the onion spike [1].
• CPI-IW, CPI-AL and CPI-RL (Labour Bureau): used for DA and wage indexation. These are different indices from CPI (Rural/Urban/Combined).

15. NCERT Concepts to Revise

• Consumer Price Index (Economy): The whole note is about how this index is built, rebased and read.
• CPI-Combined (Economy): The 6.09% headline figure is CPI-Combined, the measure behind the RBI's inflation target.
• CPI-Rural and CPI-Urban (Economy): The note compares rural inflation (6.63%) with urban (5.41%), and these two indices make up the combined figure.
• Base year (Economy): The series moved from base 2012 to 2024, which changes weights and how inflation is measured.
• Flexible inflation targeting (Economy): The 4% target with a 2-6% band is the benchmark that 6.09% is judged against.
• Monetary Policy Committee (Economy): The MPC sets the repo rate in response to inflation breaching the upper limit.
• Food inflation (Economy): Food inflation of 8.94%, with onion at 116%, is the main driver of headline inflation.
• Base effect (Economy): Flat 2025 index values explain why year-on-year inflation climbed steadily through 2026.
• Household Consumption Expenditure Survey (Economy): HCES 2023-24 supplies the spending data used to set the new CPI weights.
• Core inflation (Economy): High services inflation, such as restaurants at 10.06%, raises the question of price pressure beyond food.
• Wholesale Price Index (Economy): WPI measures wholesale prices and is compiled by a different body from CPI, a common trap in exam questions.
• CPI for Industrial Workers (Economy): CPI-IW is compiled by the Labour Bureau and is easily confused with CPI (Rural/Urban/Combined).
• Regressive tax (Economy): The note compares food inflation to a regressive tax, since poorer households spend more of their budget on food.
• National Statistics Office (Geography): The NSO under MoSPI compiles CPI and collects the price data.

16. Common Errors / Trap Areas

• Wrong compiling agency: CPI (R/U/C) is compiled by NSO-MoSPI; WPI by the Office of the Economic Adviser, DPIIT; CPI-IW, AL and RL by the Labour Bureau (MoLE).
• CFPI weight vs Food & beverages weight: CFPI is 34.78 and the Food & beverages division is 36.75. They are different aggregates [1].
• Provisional vs final figures: January 2026 was 2.75% at first release [2] and appears as 2.74% in the later series [1]. That difference comes from revision. Always check which estimate a question refers to.
• Index vs inflation rate: 110.05 is an index level, not a percentage [1].
• One month above 6% is not automatically an RBI "failure." (Unverified: the failure test is inflation staying outside the band for three consecutive quarters.)
• Base year vs weight-reference year: the base is 2024, while the weights come from HCES 2023-24 [2].
