India WPI inflation jumps to 9.68% in May 2026

Wholesale inflation moves closer to double digits

India’s wholesale price inflation (WPI) rose to 9.68% year-on-year in May, up from 8.30% in April, as cost pressures widened across fuel, food and manufacturing. The May print also marked the first reading under the revised WPI series, with 2022-23 as the base year. The move keeps wholesale inflation near the highest levels seen in recent years, after a sharp surge in April. Several reports flagged that the May reading came in above market expectations of 9.1%.

What the latest WPI data showed

Official data showed broad-based pressure from energy and input costs. Fuel and power inflation accelerated further, while food and primary articles also edged higher. Manufacturing costs were highlighted as another contributor, consistent with the idea that higher energy prices were feeding into a wider set of goods.

The May reading followed a sharp rise in April, which was described as the highest wholesale inflation level in 42 months. That April spike was also linked primarily to fuel and power prices.

Fuel and power: the biggest driver in May

The strongest push came from energy. Fuel and power inflation jumped to 30.33% in May, up from 24.89% in April. Reports attributed the pressure to elevated crude oil prices for much of the month, linked to supply concerns amid tensions in West Asia and disruption risks around key routes.

One account tied the rise in global crude to the continuing Middle East tensions linked to the US-Iran war, which strained supply chains and kept input costs high. Higher fuel costs typically flow through to freight and logistics, raising delivered prices for a wide range of goods in wholesale markets.

Food and primary articles: prices tick higher

Food inflation at the wholesale level was also reported higher in May. One set of figures put wholesale food inflation at 4.49% in May, up from 3.11% in April, reflecting increases in key agricultural commodities. Another report cited food inflation at 4.78% to 4.8%, up from 4.20% to 4.2% in April, showing broadly similar direction even where the precise number differed.

Within the broader “primary articles” bucket, which includes food items, minerals and non-food articles, inflation rose to 4.99% in May from 3.78% in April. The rise suggests that price pressures were not limited to a single commodity group.

Manufacturing and core WPI: input costs in focus

Manufacturing costs were named among the drivers behind the May rise. Earlier data for April showed manufactured product prices up 4.62% year-on-year. April also saw core WPI inflation reach 5%, described as a 43-month high, up from 3.7% in March 2026 and 1.2% a year ago.

The April breakdown pointed to energy-driven pass-through. Fuel and power inflation rose sharply, and several sub-components were also highlighted: petrol prices rose 32.40% (vs 2.50% in March), high-speed diesel (HSD) 25.19% (vs 3.26%), and LPG rebounded to 10.92% (vs -1.54%).

April set the stage: a sudden jump in wholesale prices

The May reading came immediately after wholesale inflation surged in April. WPI inflation accelerated to 8.3% in April 2026, compared with 3.9% in March 2026 and 0.9% in April 2025. Fuel and power inflation in April was cited at 24.7%, and it had jumped from 1.05% in March as energy markets reacted to the prolonged conflict in West Asia.

Food inflation in April was portrayed as relatively softer in some reports, easing to 2.3%. There were also detailed trends within foodgrains: foodgrain inflation was -1%, cereals 0.3% (vs **3.9% earlier), pulses -4% (vs -5.6%), and wheat inflation slowed to 0.4% (from 7.4%).

New WPI series: why the May print matters

May was described as the first WPI inflation reading published under a revised series with 2022-23 as the base year. A base year revision changes the reference period and can reshape weights across items in the index. While the data still showed a clear acceleration from April, investors and economists often watch the first few prints under a new series to understand how the new basket behaves during commodity swings.

Retail inflation also edged up in May

Wholesale inflation strength was mirrored by a rise in retail inflation (CPI) in May. Government data showed retail inflation at 3.93% in May, up from 3.48% in April, mainly due to rising food and fuel costs. One Reuters report noted that the increase was driven by escalating food and fuel prices, with the Middle East conflict continuing to influence the outlook.

Fuel prices were also cited as a direct contributor in May, with state-owned fuel retailers increasing fuel prices four times during the month, adding to transportation costs.

Key numbers at a glance

Market impact and why investors track WPI closely

WPI matters because it captures price changes closer to the producer and wholesale level, where energy and raw material swings show up early. The May jump to 9.68% reinforced that fuel and logistics costs were still feeding into broader pricing, including manufactured goods. With fuel and power inflation at 30.33%, sectors exposed to transport and input costs tend to be watched closely for margin pressures.

Some commentary in the reports suggested that the effects of the West Asia conflict could become more visible in CPI in the coming months, given the higher WPI readings and ongoing pressure from oil and non-oil input costs alongside supply chain disruptions.

What to watch next

The next data points investors will track are whether fuel and power inflation cools from the 30% level and whether food inflation remains elevated at the wholesale level. The trajectory of crude oil prices and supply conditions, especially around West Asia tensions, will remain central to how quickly input costs ease. For markets, the key question is how persistent the pass-through is from wholesale prices into retail inflation and company cost structures in upcoming months.
