India’s Wholesale Inflation Surges to 9.68% in May as Fuel and Manufacturing Costs Rise

India's wholesale inflation rocketed to 9.68% in May 2026, significantly higher than April's 8.26%, under a newly revised Wholesale Price Index (WPI) series with a base year of 2022-23. This surge, exceeding market expectations, is primarily fueled by escalating global energy prices, particularly crude oil and natural gas, alongside rising manufacturing costs exacerbated by ongoing geopolitical tensions in West Asia. The dramatic increase underscores India's vulnerability to external shocks and points to widespread input cost pressures across its industrial base. The acceleration in wholesale prices, particularly the 30.33% year-on-year jump in fuel and power and 7.48% in manufactured products, paints a challenging picture for the Reserve Bank of India (RBI). The RBI Monetary Policy Committee (MPC) recently held the repo rate steady at 5.25% in its June 2026 meeting but significantly raised its FY27 inflation forecast to 5.1% from 4.6%, citing global uncertainties, crude oil volatility, and supply-chain disruptions, notably from the de facto closure of the Strait of Hormuz. While the central bank primarily targets consumer price index (CPI) inflation (which stood at a 16-month high of 3.93% in May), a sustained rise in WPI is expected to feed into retail prices, further complicating the inflation management mandate and potentially dampening economic growth. India's Ministry of Commerce & Industry is phasing out the WPI over the next five years, intending to replace it with the new Producer Price Index (PPI) to align with international standards. This transition aims to provide a more comprehensive view of price pressures by including services, though the immediate concern remains managing the existing inflationary spiral. Policymakers will be closely watching crude oil price movements, which have seen recent fluctuations influenced by Middle East developments, as well as the upcoming monsoon season, both critical determinants of future inflation trajectory and the RBI next monetary policy actions. The challenge for the government and RBI lies in curbing inflation without stifling the already revised-downward GDP growth forecast of 6.6% for FY27.
