April wholesale prices rose most in 42 months as Iran war pain deepens

📌 Summary:

• Wholesale Price Index (WPI) inflation jumped to 8.3% year-on-year in April, up from 3.88% in March — the highest in 42 months
• Energy-related items contributed nearly three-fourths of the increase: ATF wholesale price more than doubled month-on-month; naphtha rose 67%, furnace oil 46%, bitumen 39%; petrol up 24%, diesel 17%, natural gas 15%, kerosene 12%, LPG 10%
• Fuel and power inflation skyrocketed to 24.71% (from 1.05%); primary articles inflation rose to 9.17%; manufactured products inflation rose to 4.62%
• Retail (CPI) inflation rose only slightly to 3.48% as the government and oil marketing companies absorbed much of the crude price shock — but producers have begun passing on costs (dining-out prices rose sharply)
• Economists warn of 'second-round effects': WPI feeds into CPI with a lag via higher input costs; CareEdge expects WPI inflation to average 7.8% in FY27 (vs 0.7% in FY26)
• A higher probability of an El Nino event adds upside risk to food inflation; wholesale food inflation was muted (2.31%) but onion prices crashed to as low as 50 paise/kg in Nashik, stressing the rural economy
