GS 3 10 Years of Flexible Inflation Targeting: Does India Need a Rethink?
Context: Marking 10 years of RBI’s Flexible Inflation Targeting (FIT), economists argue that India’s Phillips curve is largely flat and inflation expectations remain poorly anchored, questioning whether rate hikes effectively control inflation without hurting growth and employment.
10 Years of Flexible Inflation Targeting
About 10 Years of Flexible Inflation Targeting: Does India Need a Rethink?
What it is?
Inflation Targeting (IT) is a monetary policy framework where the central bank publicly announces an explicit quantitative target for the medium-term inflation rate (in India, 4% with a tolerance band of ±2%, under the amended RBI Act, 1934).
Both transmission channels rely theoretically on the New Keynesian Phillips Curve (NKPC):
where current inflation (πₜ) is a positive function of future expected inflation (Eₜ[πₜ₊₁]) and the output gap (yₜ − yₜ).* Mainstream theory presumes that as economic output expands, tighter labor markets empower workers to negotiate higher nominal wages, which firms pass into prices via markups. When inflation flares, monetary tightening slides the economy down along the NKPC, exchanging lower output for reduced price pressure.
Key Empirical Data:
Flat Phillips Curve: IIP and CPI data from April 2012 to March 2026 show an almost flat relationship (κ ≈ 0). This suggests that higher output in India does not necessarily lead to higher inflation.

Large Informal Workforce: Nearly 92% of Indian workers are in the informal sector, where wage bargaining is limited. So, an increase in economic activity may not result in strong wage-led inflation.

Gap in Inflation Expectations : RBI’s IESH shows that households generally expect inflation to be around 4 percentage points (400 bps) higher than RBI projections.

Food Dominates Inflation: Food and beverages make up 45.86% of the CPI basket. Rate hikes have limited impact on inflation caused by crop failures, supply shortages or global commodity prices.
Core Criticisms Raised Against the Framework:
The Flat Phillips Curve Dilemma : Because the NKPC is flat, hiking policy interest rates reduces domestic output and stalls capital formation without producing a commensurate decrease in inflation, risking monetary-induced stagflation.

Failure of the Wage-Push Premise: Mainstream NKPC models assume that high output strengthens worker bargaining power. In India’s informal labor market, wages remain stagnant while workers absorb price shocks as price takers.

Ineffective Inflation Tethering: The expectation channel fails because household perception is anchored heavily in daily retail food and fuel costs rather than the central bank’s published numerical path.

Disproportionate Burden on the Real Economy: High borrowing costs disproportionately squeeze micro, small, and medium enterprises (MSMEs) and prospective homeowners, curbing employment creation in manufacturing and construction.

Neglect of Supply-Side Volatility: Raising the cost of credit cannot address seasonal vegetable crop failures, geopolitical crude oil surges, or domestic supply disruptions.
Counter-Arguments: Why the RBI & Mainstream Economists Defend FIT:
Macroeconomic Stability & Lower Risk Premia : Since adopting FIT in 2016, India’s headline inflation has averaged lower and displayed significantly less volatility than during the double-digit episodes of 2009–2013, anchoring sovereign bond yields.

Preventing Generalization of Price Shocks: While interest rates cannot grow vegetables, tightening prevents temporary food and energy price shocks from embedding into core inflation and broader inflationary psychology.

Counter-Cyclical Flexibility: India practices Flexible Inflation Targeting rather than rigid strict targeting. The Monetary Policy Committee (MPC) accommodates temporary supply shocks by utilizing the full width of the 2%–6% band to support growth during downturns.
Way Ahead:
Re-Evaluating the Output-Inflation Trade-Off: The Monetary Policy Committee should formally account for labor market informality and the flat Phillips curve when determining the output sacrifice ratio during rate-hiking cycles.

Prioritizing Coordinated Supply-Side Interventions : Complement monetary policy with fiscal supply management, including targeted market interventions, dynamic food buffer-stock offloading, and strategic strategic fuel excise adjustments.

Addressing Food Price Volatility Structurally: Invest in climate-resilient cold chains, modern warehouse infrastructure, and decentralized agro-processing to stabilize perishables before price shocks require monetary tightening.

Refining Inflation Expectations Measurement : Develop nuanced surveying methodologies that distinguish between short-term grocery price perceptions and broader underlying inflation expectations.

Modernizing the CPI Consumption Basket: Accelerate the revision of the CPI weighting structure (currently using the outdated 2011–12 base) to reduce the disproportionate weight of food items in line with current household consumption trends.
Conclusion:
While the RBI’s framework has fostered macro-financial stability, an overwhelming reliance on monetary demand contraction in an economy marked by a flat Phillips curve and food-driven price swings risks curbing growth. Combining monetary vigilance with active supply-chain management and public investment is essential to stabilizing prices without compromising job creation.
