India's factory-gate inflation surged to 8.3% year-on-year in April 2026, a 42-month high and a steep rise from 3.88% in March. The Ministry of Commerce and Industry's WPI release showed a month-on-month increase of 3.86% between March and April, with the fuel and power group the principal driver. Crude petroleum and natural gas recorded an annual rise of 67.18%, while petrol and high-speed diesel inflation accelerated to roughly 32.40% and 25.19% respectively, placing pressure on manufacturers, transport operators and energy-intensive sectors. Bank of Baroda chief economist Madan Sabnavis warned that if international crude stays near the $100-120 per barrel region he cited, wholesale inflation is likely to remain elevated.

Multiple reports based on the Ministry of Commerce and Industry data put headline wholesale price index inflation at 8.3% in April 2026, the biggest jump in 42 months. The ministry's release also showed that WPI rose 3.86% between March and April on a month-on-month basis, underlining how rapidly costs moved in a single reporting period.

Energy accounts for most of the increase

The fuel and power segment was the immediate cause of the surge. Inflation in that group jumped to 24.71% in April from 1.05% in March, according to the published data. Within the group, the crude petroleum and natural gas subgroup recorded an annual rise of 67.18% in April. Several accounts of the release highlighted very large increases in crude petroleum specifically.

Petrol inflation accelerated to roughly 32.40% year-on-year in April, while high-speed diesel moved to about 25.19%. Liquefied petroleum gas swung from deflation into double-digit inflation in the same month. Industry bodies and economists cited higher international crude prices and geopolitical risk in West Asia as proximate causes, and noted the speed with which those external developments passed through into domestic fuel prices and transport costs.

That pass-through has been rapid. Reports emphasised that earlier domestic price adjustments this year, including rises in aviation turbine fuel and commercial LPG for industrial users, have already shifted costs onto commercial and industrial buyers. Household LPG cylinder prices were largely insulated in the immediate term, the data indicated, but commercial users and firms faced higher energy bills that feed into production costs.

Mastheads

Manufacturing and primary goods show broad pressure

Manufactured products, which carry about two-thirds of WPI's weight, also contributed to the headline move. The manufactured-products index rose to 4.62% year-on-year in April, up from 3.39% in March.

That upward trend was broad based.

Several reports broke the manufacturing pressures down further. Chemicals and chemical products inflation was quoted near 5.09%, basic metals around 7.00%, and textiles roughly 7.30%. Higher petrochemical feedstock costs and elevated metal prices were cited as important drivers of those increases. Some reporting offered larger increases in particular manufactured subgroups, but those figures appeared in single accounts and should be treated as single-source claims.

Primary articles also became costlier. The primary articles index climbed to 9.17% in April from 6.36% in March, supported by stronger prices for non-food articles and minerals. At the wholesale level, the food index remained relatively contained, with the food index near 2.31% and primary food articles around 1.98-1.99% year-on-year across different series.

Vegetable prices continued to show volatility. Some staple items, including potatoes and onions, remained in negative year-on-year territory in certain series, while other perishables moved seasonally. The mix meant that headline food inflation at the wholesale level didn't mirror the sharp increase seen in fuel and power.

The net effect is a WPI profile in which businesses and sectors exposed to fuel, transport and intermediate inputs feel a much larger squeeze than final consumers do at present. Still, the combination of higher input costs and rising manufactured goods inflation suggests consumer-facing prices could face upward pressure later in the year.
