India’s wholesale price inflation accelerated sharply to 8.3% year-on-year in April 2026 — more than doubling from 3.88% in March 2026 — as the Middle East war’s impact on global crude oil prices flooded through to India’s wholesale price index with full force for the first time. The data, released by the Ministry of Commerce and Industry on May 14, 2026 through PIB Delhi, marks the fastest pace of wholesale inflation in India in several years and reflects the direct transmission of the Strait of Hormuz disruption into the country’s commodity price structure.
The headline numbers
The All India WPI stood at 167.0 (provisional) in April 2026 against 160.8 in March 2026 — a month-on-month jump of 3.86%, the largest single-month WPI increase in recent memory. On an annual basis, WPI inflation at 8.3% compares with 3.88% in March, 2.26% in February, 1.68% in January, and was actually negative at -0.13% as recently as November 2025 — a trajectory that illustrates precisely how rapidly the Middle East war has transmitted into India’s wholesale price structure over five months.
Fuel and Power: The dominant driver
The Fuel and Power group — carrying a weight of 13.15% in the WPI basket — is the single most explosive component of April’s data. The group’s annual inflation rate surged to 24.71% in April 2026 from just 1.05% in March and -3.85% in February. On a month-on-month basis, Fuel and Power prices jumped 18.22% in a single month — the most dramatic monthly move in any major WPI component.
Within Fuel and Power, petrol inflation reached 32.40% year-on-year — up from 2.50% in March and -5.38% in February. High-speed diesel inflation hit 25.19% year-on-year from 3.26% in March. LPG inflation rose to 10.92% from -1.54% in March. The mineral oils sub-component saw a month-on-month increase of 29.37% in April alone — the direct and unambiguous imprint of Brent crude prices rising above $100 per barrel as the Middle East war deepened.
Crude petroleum: The most extreme data point
The crude petroleum and natural gas component — with a weight of 2.41% in the WPI — delivered the most extreme year-on-year reading in the entire dataset. Crude petroleum inflation reached 88.06% year-on-year in April 2026, reflecting the full base effect of low crude prices in April 2025 combining with the extraordinary price surge that began when the US-Israel attacks on Iran commenced in late February 2026. The crude petroleum and natural gas group overall showed 67.18% year-on-year inflation — the highest reading of any component in the April WPI data.
On a month-on-month basis, crude petroleum prices rose 16.99% from March to April alone — consistent with Brent crude’s move from approximately $70 per barrel before the war to $105-126 per barrel during April 2026.
Primary Articles: Broad-based acceleration
Primary Articles — with a weight of 22.62% — saw annual inflation of 9.17% in April 2026, up sharply from 6.36% in March. Non-food articles inflation reached 12.18% year-on-year. Oil seeds inflation stood at 22.24%. Minerals inflation hit 12.15%. The food articles component, however, showed considerably more restraint at 1.98% year-on-year — with vegetables at just 0.53%, pulses at -4.03% (deflation), and potato at -30.04% (deep deflation) — suggesting that India’s food supply chains have not yet been severely disrupted by the energy shock.
Manufactured Products: Rising but controlled
Manufactured Products — the largest WPI component at 64.23% weight — saw annual inflation of 4.62% in April, up from 3.39% in March. Basic metals inflation reached 7.00% year-on-year — reflecting the Middle East conflict’s impact on global metal prices. Textiles inflation hit 7.30%. Chemicals and chemical products rose 5.09%. Pharmaceuticals showed relatively modest inflation of 1.79%.
The manufactured products data confirms a broad-based but controlled cost-push from energy and raw material inputs flowing through the industrial production chain — 21 of 22 NIC two-digit manufactured product groups showed month-on-month price increases in April.
The WPI-CPI divergence and its policy implications
The April WPI of 8.3% sits dramatically higher than April’s CPI reading. The divergence between wholesale and retail inflation reflects the fact that the government has kept retail fuel prices frozen since April 2022 — absorbing the crude oil shock at the OMC level rather than passing it through to consumers. This is precisely the mechanism generating the ₹1,600-1,700 crore per day in under-recoveries at IOC, BPCL, and HPCL that has accumulated to over ₹1 lakh crore in ten weeks.
The WPI data makes the eventual fuel price correction even more inevitable. When retail fuel prices are finally revised — whether before May 15 as anticipated or shortly thereafter — the WPI’s Fuel and Power component will be joined by the CPI’s transport and energy components in a simultaneous inflationary impulse. RBI Governor Malhotra’s statement at the SNB-IMF conference in Switzerland that a fuel price hike is “just a matter of time” takes on additional weight in the context of WPI fuel inflation already running at 24.71%.
The WPI Food Index showed contained annual inflation of 2.31% — rising from 1.85% in March — providing some reassurance that the energy shock has not yet translated into broad food inflation. This is the primary buffer preventing a sharper CPI acceleration in the near term.
The next WPI data release, covering May 2026, is scheduled for June 15, 2026 — by which time the full impact of the government’s gold and silver import duty hike, any fuel price revision, and the continued crude oil price environment will be visible in the wholesale price structure.
