Consumer inflation rises to 3.93% in May, higher costs from West Asia war passed on to households

📌 Summary:

• CPI (retail) inflation rose to 3.93% in May 2026 (year-on-year), up from 3.48% in April; inflation has risen every month in 2026
• Causal chain — why prices are climbing: (1) producers passing on input cost rises (WPI inflation was 8.3% in April) to households; (2) West Asia war (4th month) raised commercial LPG prices → "restaurant & accommodation" inflation jumped to 5.75%; (3) heatwave conditions pushed up perishables — tomato +48% y-o-y, ginger +32%
• Food inflation rose to 4.78% (from 4.2%); Consumer Food Price Index up 0.92% month-on-month
• Forward risks: economists expect June inflation near 4.5%; monsoon forecast 10% below the Long Period Average threatens food prices; crude may stay elevated until US-Iran deal reopens the Strait of Hormuz
• Policy context: RBI''s MPC (June 5) held the repo rate at 5.25%, cut FY27 GDP growth forecast to 6.6% (from 6.9%) and raised inflation projection to 5.1% (from 4.6%); Governor Sanjay Malhotra warned average crude could be "substantially higher" than $85/bbl
• RBI''s inflation path for FY27: 4.2% (Apr-Jun), 5.1% (Jul-Sep), 5.9% (Oct-Dec), 5.4% (Jan-Mar 2027); mandate is 4% CPI within a 2-6% band

🔑 Key Term: Headline vs Core inflation — headline CPI includes volatile food and fuel; "core" strips them out; the West Asia war is transmitting via the food/fuel components here.
