Keeping India’s 4% inflation target makes sense through an oil shock

India is right to keep headline inflation as the Reserve Bank’s target through the next five years. The Finance Ministry’s notification retains a 4% target with a lower tolerance level of 2% and an upper one of 6%, from 1 April 2026 through 31 March 2031. The decision comes at a moment when energy costs are testing the difference between a price shock and an inflation process. The RBI should explain which part of the increase it expects to fade, which part could spread to other prices and what it would do if that spread becomes visible. A stable target is useful precisely because the correct policy rate can change with the source of the shock. Gazette notification on the inflation target · Reuters on the renewed target

The midpoint is the target, and the band allows for shocks

The monetary framework gives the committee a point target of 4% and room for temporary deviations. The RBI’s review describes the accountability test as a deviation outside the tolerance band for three consecutive quarters. The rule makes prolonged misses consequential. It does not require a change in the policy rate after one monthly print or treat 6% as the objective whenever inflation is below it. The published February CPI reading, at 3.21% year on year on the new base, is a useful starting point. It measures prices before the recent phase of the energy shock and cannot settle where inflation will be once firms and households respond.

The reason to keep the midpoint unchanged is that an inflation target also coordinates behaviour. A firm writing annual contracts and a household negotiating wages have to form a view of next year’s prices. An announced increase in the target in response to a shock could cause them to revise that view even if the immediate price rise would otherwise have faded. That would make a temporary shock more persistent. Maintaining the target preserves a reference point while allowing the RBI to explain why it is willing to take time to bring inflation back toward it. The credibility of that explanation depends on the quality of its forecasts and whether it follows through when inflation broadens. RBI’s review of the monetary policy framework

Headline inflation answers a welfare question that core cannot

The strongest argument for a core target is that food and fuel prices can move for reasons the repo rate cannot quickly fix. Higher rates will not produce more onions, replenish imported energy or clear a shipping bottleneck. A central bank that tried to reverse every such move could depress investment and employment while the original shortage persisted. Core measures can help identify underlying pressure. The problem with a core target is that food and fuel are part of the spending households actually need to finance. If those prices rise persistently, they can affect wage demands, discretionary spending and the prices businesses set. The headline is the right object for the public commitment, while measures of persistence and breadth inform the policy response. RBI’s review of the monetary policy framework

A simplified calculation illustrates the difference. Take a hypothetical economy where an energy-sensitive group represents 10% of the household basket and its price rises 12% once, starting from base weights. With all other prices unchanged, that lifts the overall price index by 1.2%. If the group then stays at the higher level and everything else is flat, the direct contribution to year-on-year inflation drops out once the comparison month also contains the higher price. If transport, packaged goods and services reprice repeatedly in response, the contribution becomes wider and more persistent. The assumed 10% weight is illustrative. The new CPI groups household energy, transport and related items in ways that require more detail for an actual estimate. MoSPI’s February inflation release

The distinction does not make a one-off rise harmless. A household with fixed cash income still loses purchasing power when prices settle at a higher level. Lower-income households may also have less room to reduce fuel or food use without giving up other essentials. Governments can address some of that distribution through targeted transfers or measures that relieve supply constraints. Blanket price suppression has its own costs. If a retail price stays flat because a public enterprise absorbs the increase, the household index can look better while the financial burden accumulates elsewhere. Monetary policymakers should look through the right price movements and still account for the economy-wide cost of the shock.

A stable target is compatible with different policy paths

The RBI’s 2025 review says headline inflation averaged 4.9% after the adoption of flexible targeting in its sample, against 6.8% in the preceding period of the same series. That is a useful record and an imperfect estimate of what the framework caused. Food supply, global energy, fiscal decisions and the pandemic also changed across those periods. A stronger test is whether medium-term expectations remained anchored through shocks and whether inflation returned toward the target without unnecessarily large losses of activity. The review records that the MPC met under the accountability provision in November 2022 after a sustained overshoot. The framework can therefore accommodate volatility while still requiring an explanation when the breach persists. RBI’s review of the monetary policy framework

Suppose the initial oil shock weakens real household demand and firms in most sectors still struggle to raise prices. A pre-emptive tightening would then impose a second cost on borrowers and investment. Suppose instead that the rupee depreciates, wage settlements accelerate and services prices start rising across categories even as the original fuel increase slows. That would make a stronger case for resisting the spread. These are different scenarios, not forecasts. The committee can make its reaction function clearer by showing how its projected headline path changes under each and explaining the evidence that would switch its preferred response. Publishing a single conditional path without its most consequential assumptions leaves too much of the decision implicit.

Flexibility should be symmetric. A sustained fall below 2% can be a sign that the economy is weak enough to justify easing, even when cheaper food has initially helped households. For a borrower facing fixed nominal payments, lower expected inflation raises the real burden of the debt at a given interest rate. The same monetary regime should therefore require the committee to explain persistent undershoots. A temporary fall in a few fresh food prices is different from broad disinflation accompanied by slower sales and investment. The case for waiting or acting should rely on the breadth of the movement and what it implies for the forecast, just as it does when inflation is above the midpoint.

Forecasts would be easier to evaluate if the RBI separated its assumptions about world oil prices, the rupee and domestic pass-through. The same imported cost shock can reach the CPI quickly if retail prices adjust or more slowly if duties, contracts or company margins absorb it. A forecast that assumes one of these paths should state it. The committee should then compare the realised path with the forecast and explain whether the error came from energy prices, the exchange rate or the behaviour of domestic prices. This is useful accountability even when inflation stays within the band. It would help readers judge whether a change in the outlook warrants a change in the rate.

Judge the framework by what it explains when the outlook changes

Track household and business inflation expectations at several horizons, the breadth of price rises beyond food and energy, and evidence that wage and margin decisions have begun to respond. Also watch lending and demand so that the committee can distinguish persistence from a shock that is already squeezing spending. If expectations and broader prices remain stable, patience through a temporary overshoot can be consistent with a credible target. If the pressure spreads or expectations move, the case for a policy response strengthens. Keeping the same 4% anchor is sensible. The value of that decision will be measured by how clearly the RBI explains and manages the trade-offs around it.
