Food inflation

Topic: Inflation and Index Numbers: CPI, WPI, IIP and the Deflator · NCERT: Beyond NCERT

Meaning

Food inflation is the year-on-year (y-o-y) rise in the prices of food items that households buy. In India, MoSPI measures it with the CFPI (Consumer Food Price Index).

Food inflation (%) = (CFPIₜ − CFPIₜ₋₁₂) / CFPIₜ₋₁₂ × 100

• CFPIₜ is the food index for this month.
• CFPIₜ₋₁₂ is the food index for the same month last year.
• This is the same y-o-y formula MoSPI uses for CPI inflation [1].

Why it matters:

• Food carries a large weight in India's CPI, so food prices can push the headline inflation rate up or down.
• Food price shocks usually come from the supply side, such as the monsoon, heatwaves and crop damage. Interest rate policy cannot easily control these.

Explanation

How food inflation feeds into headline CPI

• Headline CPI inflation means inflation for the full basket of goods and services. It is a weighted average: each item's price change counts according to its share in household spending.
• The larger the food weight, the more a food shock moves headline inflation.
• CPI 2012 (Combined): Food and Beverages weight = 45.86% (NCERT says about 46%) [1].

• CPI 2024 (Combined): 36.75% under the new COICOP structure. Under the old classification it would be 40.10% [1].

• Worked example (effect of weight):

• Suppose food inflation = 10% and non-food inflation = 3%.
• With the 2012 weight: 0.4586 × 10 + 0.5414 × 3 ≈ 6.2% headline.
• With the 2024 weight: 0.3675 × 10 + 0.6325 × 3 ≈ 5.6% headline.
• The same food shock now moves headline CPI less.

Why food prices swing so much

• Supply depends on the monsoon.
• A weak monsoon, a heatwave or unseasonal rain can damage crops quickly.

• Supply falls quickly, but people still need to eat → prices jump.

• TOP crops (tomato, onion, potato) are perishable.

• They spoil fast, and India has little storage for them.

• So even a small supply loss causes a big price jump.

• Seasons matter. Vegetables are cheap in winter, for example. Comparing a month with the same month last year removes most of this seasonal effect.

• Structural pressure (protein inflation): as incomes rise, people eat more pulses, milk, eggs, meat and fish. Demand grows faster than supply, so prices rise over many years. This is a long-term cause, not a seasonal one.

Base effect and momentum in food prices

• Base effect: y-o-y inflation also depends on the price level a year ago (the "base").
• Low base (for example, a vegetable glut last year pulled prices down) → the denominator is small → this year's rate looks high.

• High base (a price spike last year) → the denominator is large → this year's rate looks low, even if prices are still rising.

• Momentum = the month-on-month (m-o-m) price change in the current month. It shows the real price pressure right now.

• Change in y-o-y inflation ≈ momentum now − momentum in the same month a year ago (base effect) [3].
• Worked example (high base):
• Food index: June 2024 = 100, July 2024 = 104 (a one-month spike). June 2025 = 105, July 2025 = 105.5.
• June 2025 inflation = 5%. July 2025 inflation = (105.5 − 104)/104 × 100 ≈ 1.44%.
• Prices still rose, but the headline rate fell sharply.

In India

• Who measures it: MoSPI publishes CPI and CFPI every month.
• Its Field Operations Division of NSS collects prices from 1,465 rural and 1,395 urban markets in 434 towns (CPI 2024 series) [1].

• Prices from 12 online markets are collected weekly [1].

• New CPI series (base 2024 = 100): released on 12 February 2026, starting with data for January 2026 [1][2]. Weights come from HCES 2023-24 (Household Consumption Expenditure Survey) [1].

• Latest figure: CFPI food inflation was 2.13% in January 2026 (provisional; rural 1.96%, urban 2.44%) [2].
• Rural households are hit harder, because food takes a bigger share of their spending. Under the old structure, the rural food weight was 54.18% (2012) → 44.80% (2024), and the urban weight was 36.29% → 34.26% [1].
• Why the food weight is falling: as incomes rise, households spend a smaller share of their budget on food. This is Engel's law.
• Food inflation in RBI's own assessments:
• May 2021: RBI said high momentum in food, fuel and core items, together with an unfavourable base effect, pushed headline inflation up [3].

• September 2024: RBI said an adverse statistical base effect was made worse by a fresh rise in food price momentum [4].

• The inflation target applies to headline CPI, which includes food: 4% CPI inflation, with a band of 2–6%. The Central Government sets it in consultation with RBI under Section 45ZA of the RBI Act. It was first notified on 5 August 2016 [7].

• Supply-side policy for TOP crops:
• Operation Greens was announced in the Union Budget 2018-19 with ₹500 crore and modelled on Operation Flood. It was launched by the Ministry of Food Processing Industries (MoFPI) in November 2018 [5].
• Short term: a 50% subsidy on transport and storage. Long term: grants of 35–70% of project cost (up to ₹50 crore per project) for value-addition projects [5].
• The MIEWS portal (Market Intelligence and Early Warning System) tracks TOP prices and sends alerts so the government can step in early [6].

Don't confuse with

• Headline inflation: this covers the whole CPI basket. Food inflation covers only the food part. With the CPI 2024 weights, food makes up about 36.75% of headline CPI [1].
• Core inflation: this is headline inflation after removing volatile food and fuel. It shows demand-side pressure. Food inflation shows supply-side pressure.
• Skewflation: here, prices of a narrow group (such as pulses or onions) rise sharply while overall inflation stays moderate. Food inflation is the rise in the whole food index, not just a few items.
• Food disinflation vs food deflation: if food inflation falls from 6% to 4%, that is disinflation, and food prices are still rising. Only a negative rate means food prices are actually falling (deflation).

Prelims Hooks

• Food inflation is measured by the CFPI (Consumer Food Price Index), published by MoSPI. It is not published by RBI or DPIIT.
• Food and Beverages weight (Combined CPI): 45.86% in CPI 2012 → 36.75% in CPI 2024 (COICOP structure) [1]. The fall reflects Engel's law.
• Rural CPI has a higher food weight than urban CPI in both series [1].
• CFPI food inflation was 2.13% in January 2026 (provisional), the first month of the new CPI series with base 2024 = 100 [2].
• Trap: Operation Greens (TOP crops) is run by MoFPI, not the Agriculture Ministry. It was announced in Budget 2018-19 with ₹500 crore [5].
• High base effect: a food price spike last year lowers this year's y-o-y food inflation, even when prices are still rising.

Mains Points

• Food inflation and monetary policy: food shocks come from the monsoon, heatwaves and the perishability of TOP crops. These are supply shocks, and raising the repo rate (the rate at which RBI lends to banks for a short time) cannot grow more onions. RBI therefore watches food momentum and tries to "look through" rises that come only from the base effect. The cut in the food weight from 45.86% to 36.75% (CPI 2024) [1] makes headline CPI a better guide to demand-side pressure under the 4% (2–6%) target [7].
• Supply-side fixes are needed: storage, cold chains, transport support and early-warning systems work at the root of TOP price swings. Examples are Operation Greens [5] and MIEWS alerts [6]. Protein inflation also needs more output of pulses, milk and eggs, not only price control.
• Equity angle: food takes a larger share of spending for poor and rural households. So food inflation and skewflation hurt them more than headline CPI shows. This matters for wage indexation, DA (dearness allowance) and the real value of welfare benefits.
