Recent data and Reserve Bank of India projections underpin the 98% implied probability for India’s 2026 annual CPI inflation exceeding 4.5%. September’s 5.54% print, following August’s 4.8% rise, reflects broadening pressures from food inflation near 7.7%, elevated fuel costs, and a deficient monsoon amid El Niño conditions. The RBI’s October update lifted its FY27 forecast to 5.2%, citing ongoing supply-side risks and core inflation at 4.2%, with quarterly peaks expected near 6%. Trader consensus aligns with these official estimates and recent prints rather than lower historical averages. A sharper decline in global oil prices, stronger rabi output, or faster policy transmission could still pull the full-year average below 4.5%, though such shifts appear limited by current momentum.
