India is the world's most populous country and its fifth-largest economy — and it faces an inflation challenge that is structurally different from what Western central banks deal with. With food and beverages accounting for 45.9% of the CPI basket (versus ~14% in the US), a single bad monsoon season or a surge in onion and tomato prices can push headline CPI 1–2 percentage points above target within weeks. The Ministry of Statistics and Programme Implementation (MoSPI) publishes monthly CPI data; the long-run series is available via World Bank WDI.
The monsoon-food-CPI transmission
India's food price inflation is uniquely sensitive to weather. The southwest monsoon (June–September) determines crop yields for rice, wheat, vegetables, and pulses across most of the country. A deficient monsoon (below-average rainfall) reduces supply and pushes prices up within 1–3 months of harvest. In 2023–2024, irregular monsoon patterns drove tomato prices up over 200% and onion prices up 60% at various points — single items that collectively pushed food CPI into double digits. The Directorate of Economics and Statistics tracks crop output, and the Reserve Bank of India's monetary policy page contains the MPC statements that explain how these food shocks feed into the inflation forecast.
Core inflation: a different story
India's core CPI (excluding food and fuel) has been remarkably well-contained at 3.3% in September 2026 — well within the RBI's 2–6% tolerance band. This split between elevated headline (food-driven) and subdued core is a recurring pattern in India: it reflects domestic supply-side food price volatility rather than demand-pull inflation. The RBI's monetary policy framework requires it to target headline CPI — not core — which means it must respond to supply-driven food shocks even when core is benign. The IMF India Article IV consultation and the OECD India economic survey both discuss this structural challenge. Track India's inflation history on our India inflation chart.
