Why Inflation Targeting Matters
India’s Flexible Inflation Targeting (FIT) framework—4% target with a ±2% band—comes up for review in March 2026. RBI’s recent discussion paper reassesses whether this target continues to protect growth, household welfare, and macroeconomic stability.
Inflation is not just an economic metric; it is a silent tax that hurts the poor most. High inflation discourages investment, erodes savings, and distorts consumption. Since 2016, FIT has anchored expectations and strengthened India’s monetary credibility.
Understanding Inflation Indexes in India
Major Inflation Indices in India
Index | Measured by | What it captures | Use in policy |
| WPI (Wholesale Price Index) | Ministry of Commerce | Prices of commodities at wholesale level; no services | Earlier main index; now secondary |
| CPI (Consumer Price Index) – Combined | NSO | Retail inflation for households; includes food, services | Primary anchor for FIT |
| CPI – Rural / Urban | NSO | Consumption baskets for rural & urban families | Welfare policymaking |
| Core Inflation | Derived | CPI excluding food & fuel | Tracks underlying price pressures |
Why CPI is used for FIT: It better reflects household welfare, especially food inflation, which dominates India’s consumption basket.
What Should India Target? Headline or Core?
RBI’s analysis suggests:
- Headline inflation should remain the benchmark because food & fuel matter for welfare and political stability.
- Core inflation is useful for trend detection, but not ideal for India’s lived reality.
Is 4% the Right Target? Evidence Says Yes
RBI finds a non-linear relationship between inflation and growth (using post-1991 data).
- Very low inflation → suppresses growth & investment
- Very high inflation → erodes consumption & stability
- Optimal inflation for India ≈ 3.8% → rounded to 4%
This protects poorer households while ensuring predictability for businesses and investors.
The +/-2% Band: Should It Change?
India’s band provides flexibility during supply shocks (COVID-19, oil spikes). But staying near 6% too often weakens RBI credibility.
RBI concludes the 2–6% band is appropriate, though the central bank must avoid operating close to the upper limit for long periods.
Inflation–Growth–Policy: An Integrated View
What FIT Achieves | What Challenges Persist | What India Needs to Do (Policy Directions) |
| Anchors expectations for households & markets | Cannot control food supply shocks | Strengthen food supply chains and logistics |
| Enhances monetary credibility | Fiscal slippages weaken impact | Maintain fiscal discipline to support monetary policy |
| Supports long-term investment stability | Rising climate-linked volatility | Improve inflation forecasting with climate models |
| Prevents political interference in monetary decisions | High food weight makes inflation control complex | Clear policy communication to anchor expectations |
India’s inflation targeting model balances stability with growth, but works best when fiscal and supply-side policies support RBI action.
