PIB TrackerWholesale inflation at 9.87% in June — WPI runs well above retail CPI, led by fuel and mineral oils
Provisional Wholesale Price Index (WPI) inflation for June 2026 was 9.87% year-on-year (up from 9.68% in May), on the 2022-23 base — running far above the 4.38% retail (CPI) print, a producer-vs-consumer price divergence driven by Fuel & Power (27.41%), mineral oils and basic metals.
What happened
- Wholesale (WPI) inflation was 9.87% year-on-year in June 2026, up from 9.68% in May, on the 2022-23 base.
- The All Commodities index was 110.2 (from 109.9 in May).
- By major group: Fuel & Power 27.41%, Primary Articles 7.0%, Manufactured Products 7.48%.
- Mineral oils, food articles, basic metals and chemicals were the biggest drivers; the WPI Food Index rose 6.14% (from 4.49%).
- Notably, WPI (9.87%) ran well above retail CPI (4.38%) — a producer-vs-consumer price wedge driven by energy and industrial inputs.
For Prelims
- WPI: The Wholesale Price Index tracks prices at the wholesale/producer level; it is compiled by the Office of the Economic Adviser, DPIIT (Ministry of Commerce & Industry).
- Base year 2022-23: The WPI series shown here uses the 2022-23 base (index = 100 in the base period), refreshing weights and the item basket.
- WPI has no services: Unlike CPI, WPI covers only goods — Primary Articles, Fuel & Power, and Manufactured Products; Manufactured Products has the largest weight.
- RBI targets CPI, not WPI: Monetary policy is anchored to retail CPI (4% ±2%); WPI is a supplementary gauge of cost pressure, useful for the GDP deflator and producer margins.
- WPI > CPI: A wide gap (here 9.87% vs 4.38%) usually signals producer-side/energy cost pressure not yet passed on to consumers, or divergent basket weights (fuel weighs more in WPI).
- WPI Food Index: Combines 'Food Articles' (Primary) with 'Manufacture of Food Products' (Manufactured) — a cross-cutting read on food prices at wholesale.
For UPSC: Use this alongside the CPI print for the inflation and monetary-policy story — and specifically for the WPI-vs-CPI divergence (9.87% vs 4.38%): why the two indices differ (coverage of services, basket weights, wholesale vs retail stage), and why fuel/energy and industrial inputs drive WPI. Anchor the WPI's structure (three groups, no services, DPIIT compilation), the RBI's CPI-only targeting, and the pass-through question.
What it is NOT: This is a provisional monthly statistical release (base 2022-23), not a policy decision — and WPI is not what the RBI targets (that is retail CPI). The high WPI reading does not by itself imply a rate action; it flags producer-level cost pressure, chiefly in fuel/energy and industrial inputs.
For Mains
Syllabus: GS3.1 · Linkage L2
Anchor
Price measurement and cost pressure — wholesale inflation running well above retail, signalling producer-side energy and input-cost stress.
Substantiation (data)
June 2026 WPI 9.87% YoY (base 2022-23; index 110.2); Fuel & Power 27.41%, Primary Articles 7.0%, Manufactured Products 7.48%; WPI Food Index 6.14%; vs retail CPI 4.38%.
Exemplification
Mineral oils, food articles, basic metals and chemicals as the swing drivers; WPI's heavier fuel weight amplifying energy shocks relative to CPI.
Problematisation
A wide WPI-CPI wedge complicates the inflation read — producer costs may pass through to consumers with a lag, squeezing margins; energy/import prices remain the key risk.
Way-forward
Monitor pass-through from wholesale to retail, manage fuel and input-cost volatility, and keep monetary policy anchored to CPI while watching WPI as a leading cost gauge.
Position
WPI is a diagnostic of cost-push pressure, not a policy target; the RBI's flexible inflation targeting stays anchored to retail CPI within the 2-6% band.
Deploys into: Indian economy — inflation and price indices (GS3.1) · the WPI (wholesale, goods-only, DPIIT) vs the CPI (retail, RBI-targeted), basket weights, and the WPI-CPI divergence as a cost-pressure signal.
