Inflation targeting in India
Targeting a consumer price index in an economy where food and fuel swing violently, with a tool that works on demand. The design choices follow from that tension, and so do the criticisms.
Chapter 9 · Advanced
India targets headline CPI at 4%, within a 2–6% band. Both halves of that choice are contested, and the arguments are worth understanding because they recur every time inflation moves.
The instrument and the problem do not match
Monetary policy works on demand. Raising rates makes borrowing dearer, investment and consumption fall, and price pressure eases.
A large share of Indian inflation is supply-driven: food prices moving with the monsoon, fuel prices moving with global crude and the exchange rate. Food and fuel together are a far larger share of the Indian consumption basket than in richer economies, which is exactly why they dominate the index.
Rates do not grow vegetables. A monsoon failure raises prices for reasons no interest rate can address, and raising rates in response imposes a cost on the whole economy without touching the cause.
Headline or core
This is the central design argument.
The case for core — stripping out food and fuel — is that it isolates the demand-driven component policy can actually influence. Targeting headline means responding to noise, and responding with a tool that does not work on it.
The case for headline, which India chose, has three parts and they are strong:
It is what households experience. Core inflation excludes most of what a poorer household spends its money on. A target that excludes food in an economy where food is a large share of the basket is a target disconnected from the people it exists to protect.
Food inflation is not always temporary. Repeated shocks keep the price level rising, and "look through it" becomes a policy of never responding.
Expectations are the real mechanism. This is the decisive one. If households and firms expect high inflation, they demand higher wages and set higher prices, and the expectation becomes self-fulfilling. Expectations are formed from the prices people actually see, which are headline prices — so a central bank that ignores headline while the public does not is losing the anchor it most needs.
That last point is why the answer to the problem is not simply "do nothing".
The honest answer to the monsoon case
Both sides, as the problem asks.
Do not raise. The shock is supply-side and temporary. Core is steady, so there is no demand pressure. Raising rates damages growth to address a cause rates cannot reach, and the price spike will reverse when the next harvest arrives.
Raise. A sustained breach of the band risks un-anchoring expectations, and once wage and price setting start assuming higher inflation, bringing it back costs far more than acting early. The target is headline for exactly this reason, and a target abandoned whenever it is inconvenient is not a target.
What to actually do: this is what the band and the horizon exist for. Tolerate the breach while it is clearly a supply shock, communicate plainly that it is one, and watch two things — whether it is spreading into core, and what survey measures of inflation expectations are doing. Act on the second derivative, not the headline. If expectations drift, the shock has stopped being temporary regardless of its origin, and then rates are the right tool.
That is flexible inflation targeting working as designed rather than being set aside.
What the framework achieved
Before 2016 there was no numerical target and no committee. Three things changed:
- An anchor. A published number gives households, firms and markets something to form expectations around, which is most of what monetary policy does.
- Accountability. Published votes, published minutes, and a formal explanation required for sustained breach.
- Predictability. Market participants can forecast policy because the objective is stated. That improves transmission (chapter 7), because expectations move rates before the RBI does.
The standing criticisms
It is the wrong target for a developing economy. Growth and employment matter more where incomes are low, and a single-minded inflation focus may cost output.
The band is wide. A 4-point range leaves considerable latitude, so the target constrains less than it appears to.
Transmission is incomplete (chapter 7), so the instrument is weaker than the framework assumes.
Fiscal dominance. Large government borrowing can push rates independently of monetary policy, and the RBI manages that debt — which is the structural conflict of chapter 5 arriving in practice.
None of these is settled. They are the reasons the target is reviewed every five years rather than fixed permanently.
The point
India targets headline CPI at 4% within a 2–6% band, in an economy where food and fuel swing for reasons monetary policy cannot touch. Headline was chosen over core because it is what households actually experience and therefore what forms expectations — and expectations are the mechanism a central bank can genuinely lose. The band and the horizon exist so that a supply shock can be tolerated while it is watched for signs of spreading into core.

Now do it with your own numbers
A monsoon failure pushes vegetable prices up and CPI above 6%. Core inflation is steady. Argue both sides of whether the MPC should raise rates, then say what you would actually do.
Rates do not grow vegetables. But the target is headline, not core, and expectations are the thing a central bank can genuinely lose.
