10 Years of Flexible Inflation Targeting: Is India’s Monetary Policy Framework Due for a Rethink?

Context

A decade after India formally adopted Flexible Inflation Targeting (FIT), the framework is facing renewed debate. The central concern is whether conventional interest-rate adjustments are sufficiently effective in an economy where the relationship between growth and inflation appears weak, inflation expectations are not firmly anchored, and food prices account for a large part of consumer inflation.

What is Flexible Inflation Targeting?

Flexible Inflation Targeting is a monetary-policy regime under which the central bank seeks to maintain inflation around a publicly announced numerical target while also allowing room to support economic growth.

• India targets 4% CPI inflation, with a tolerance range of 2%–6%.
• The framework was formally institutionalised in 2016 through amendments to the RBI Act, 1934.
• The Monetary Policy Committee (MPC) determines policy rates with price stability as the primary objective, while keeping growth considerations in view.
• Its theoretical foundation is closely linked to the New Keynesian Phillips Curve (NKPC), which broadly connects inflation with expected future inflation and economic slack.

Why is India’s Phillips Curve Debate Important?

The Phillips Curve traditionally suggests a trade-off between economic activity and inflation: stronger demand and tighter labour markets can raise wages and eventually prices.

However, Indian evidence presents a different picture.

• Weak output-inflation relationship: Data covering roughly 2012–2026 indicate an almost flat Phillips Curve, suggesting that stronger output does not automatically generate proportionately higher inflation.
• Informal employment structure: With the overwhelming majority of workers outside formal employment, stronger economic activity may not translate into substantial wage bargaining or wage-driven inflation.
• Food-led inflation: Food and beverages constitute around 45.86% of the CPI basket, making inflation highly sensitive to agricultural and supply-side disturbances.
• Poorly aligned expectations: Household inflation perceptions can remain significantly above the RBI’s projected inflation path, particularly because people experience inflation through everyday purchases of food and fuel.

Major Concerns with the Existing Approach

1. The Flat Phillips Curve Problem

If inflation responds only weakly to changes in domestic demand, aggressive monetary tightening may reduce output and investment without delivering a comparable decline in inflation.

This raises the possibility of an unnecessarily high output sacrifice for achieving price stability.

2. Limited Wage-Price Transmission

The conventional wage-price mechanism is less powerful when a large informal workforce has weak bargaining power. Workers may absorb higher living costs rather than negotiate substantially higher wages, weakening the conventional transmission from employment to inflation.

3. Inflation Expectations Remain Difficult to Anchor

Households often form expectations from frequently purchased items. A spike in vegetables, cooking fuel or transport costs can therefore influence perceived inflation more strongly than the RBI’s numerical target.

4. Interest Rates Cannot Directly Fix Supply Shocks

Monetary tightening cannot increase vegetable production after crop damage, repair disrupted supply chains or directly reduce an international crude-oil shock.

Using higher borrowing costs against such inflation can instead affect investment, housing and employment.

5. Pressure on Investment and MSMEs

Higher interest rates raise financing costs for businesses, particularly smaller enterprises that depend heavily on bank credit. Prolonged tightening can discourage capacity expansion and weaken employment generation.

Why Should FIT Still Be Retained?

Despite these limitations, abandoning FIT would be premature.

• Greater macroeconomic stability: The post-2016 period has generally witnessed lower and less volatile inflation than the high-inflation years preceding FIT.
• Anchoring broader price behaviour: Monetary tightening can prevent temporary food or energy shocks from spreading into wages, core prices and longer-term inflation behaviour.
• Improved credibility: A clearly defined inflation target gives households, investors and financial markets a predictable policy reference point.
• Exchange-rate stability: Maintaining an appropriate real-interest-rate differential can help reduce pressures on capital flows and the rupee during periods of global monetary tightening.
• Built-in flexibility: India does not follow a rigid inflation-only regime. The 2%–6% tolerance band gives the MPC some space to accommodate temporary supply shocks while considering growth.

The Larger Policy Challenge

The debate should therefore not be framed simply as “FIT versus no FIT.” The more relevant question is whether India’s inflation-targeting framework is adequately adapted to the structure of the Indian economy.

India’s inflation dynamics are shaped substantially by:

• agricultural supply disruptions;
• global energy and commodity prices;
• weather-related shocks;
• food-storage and logistics bottlenecks;
• exchange-rate movements; and
• changing consumption patterns.

These factors cannot be managed through interest rates alone.

Way Forward

• Reassess the output-inflation trade-off: The MPC should give greater analytical weight to India’s informal labour market and the apparently weak output-inflation relationship while assessing the costs of monetary tightening.
• Strengthen monetary-fiscal coordination: Interest-rate policy should be complemented by timely food-market interventions, buffer-stock management and calibrated fiscal measures.
• Build resilient food supply chains: Better cold storage, warehousing, transport and agro-processing can reduce the frequency with which temporary supply disruptions turn into persistent price pressures.
• Improve inflation-expectation surveys: Measurement should distinguish between short-term perceptions driven by grocery prices and expectations regarding broader, persistent inflation.
• Update the CPI basket: The consumption basket should be periodically revised to better reflect contemporary household spending patterns rather than relying excessively on older consumption weights.
• Preserve RBI credibility: Any reform should strengthen, rather than dilute, the transparency, accountability and predictability established under FIT.

Conclusion

Ten years of FIT demonstrate that credible inflation management matters, but India’s experience also shows the limits of relying predominantly on monetary demand compression. A relatively flat Phillips Curve, a large informal workforce and substantial food-driven inflation weaken the effectiveness of conventional rate hikes in dealing with every inflationary episode.
