1 · What is the news?

Let us understand this inflation spike in simple words! For more than ten years, wholesale price inflation in India stayed very low. But suddenly, Wholesale Price Index (WPI) inflation shot up from near zero to roughly 10% (9.87%) by June 2026.
Why is this happening? Many students think prices rise only when people have too much money and buy too many things (excess demand). But official data shows a different story today! Our inflation is happening because making things has become expensive due to high global oil prices, and because erratic monsoons have damaged farm crops.

2 · Why Are Prices Going Up?

Step 1: Expensive Global Crude Oil (Fuel & Power Spike)
Global oil prices jumped. Since factories need oil and transport for everything, general manufacturing costs shot up immediately.
▼
Step 2: Factories Pass on the Burden (Cost-Push)
To protect their profits, companies pass these high fuel and raw material costs directly to customers, raising factory-gate prices.
▼
Step 3: Bad Monsoons Hurt Crops (Food Inflation)
Erratic monsoons and El Niño damage crops like tomatoes and vegetables. With less food coming to markets, vegetable prices jump!
▼
Step 4: The Tax Cushion Was Removed (Policy Shift)
Earlier, the government cut excise duties on petrol when global oil soared. Stopping this helpful tax cushion left domestic wholesale prices exposed!

3 · Key Economic Concepts Explained Simply

How Pricing Works
Kalecki’s Simple Rule
Economist Michal Kalecki taught us: Farm prices change based on demand and monsoons. But factory prices change based on input costs (like fuel and electricity), not just how much consumers buy!
WPI vs. CPI Basics
Bulk vs. Shop Prices
WPI tracks bulk wholesale factory prices and ignores services (released by DPIIT). CPI tracks retail shop prices including services like health and education (released by NSO/used by RBI).
Why RBI Can’t Fix This
Limits of Repo Rates
The RBI raises interest rates to cool down public spending. But when inflation is caused by expensive global oil or poor rainfall, raising bank loan rates cannot make crude oil cheaper or make it rain!
The Real Solution
Better Irrigation Networks
Relying purely on rain for farming is outdated! To permanently stop food inflation, India must aggressively expand modern irrigation networks through schemes like PMKSY (Har Khet Ko Pani).

UPSC Prelims Quick Facts: Inflation & WPI
Who Publishes WPI? Office of the Economic Adviser, DPIIT, under the Ministry of Commerce & Industry publishes WPI monthly.
WPI Basket Weightage Manufactured Products (~64.2%, highest) > Primary Articles (~22.6%) > Fuel & Power (~13.1%).
Countercyclical Tax A helpful fiscal policy where the government cuts customs or excise duties when global prices spike to protect domestic buyers.
PMKSY Aim Pradhan Mantri Krishi Sinchayee Yojana aims to ensure assured water access to every farm (“Har Khet Ko Pani”), reducing monsoon dependence.

MCQ Practice Question
Q. With reference to price indices and inflation measurement in India, consider the following statements:

  1. The Wholesale Price Index (WPI) is published monthly by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation.
  2. Unlike the Consumer Price Index (CPI), the WPI basket does not capture price fluctuations in the services sector.
  3. In the current WPI series, “Manufactured Products” carry the highest weightage among all major commodity groups.

Which of the statements given above is/are correct?
(a) 1 and 2 only    (b) 2 and 3 only    (c) 1 and 3 only    (d) 1, 2 and 3

Answer: (b) 2 and 3 only

  • Statement 1 — Incorrect (the trap): WPI is published by the Office of the Economic Adviser, DPIIT (Ministry of Commerce & Industry)! It is the retail CPI that is published by the NSO (MoSPI).
  • Statement 2 — Correct: WPI measures wholesale factory goods only. It completely excludes services (like education, healthcare, and IT), whereas CPI includes them.
  • Statement 3 — Correct: Manufactured Products account for roughly 64.2% of the entire WPI basket, holding a much larger weight than Primary Articles or Fuel & Power.
