The problem is inflation’s second-round effects

Why in the News

The Monetary Policy Committee (MPC) has voted to raise interest rates and to shift its stance to calibrated tightening, which signals further rate rises. The increase was unanimous, but two members voted against the change of stance, preferring a neutral posture. How far tightening now goes turns on whether second-round effects take hold.

What are second-round effects, and why do they decide the next move?

1. Second-round effects: A shortage raises prices once. Second-round effects follow when workers ask for higher wages and sellers raise prices in advance, so a one off jump becomes lasting inflation.
2. Supply side inflation: Prices pushed up by scarce food or costly energy pass through the index once and then fade.
3. Why the distinction decides policy: Interest rates cannot add rainfall or oil. They cool demand, so more tightening is justified only where price rises have spread.
4. The takeaway: The argument inside the committee is not about the latest inflation reading. It is about whether the shock is being built into wages and prices.

Where do the committee’s members differ?

1. Supply side reading: One member argued that inflation is driven largely by supply side factors and shows no sign of overheating or of becoming generalised.
2. Entrenchment reading: Another member cautioned that the data increasingly suggests price pressures are getting entrenched, meaning built into the economic system’s wages and prices.
3. The Governor’s reading: The Reserve Bank of India (RBI) Governor saw rising signs of generalisation, meaning price rises spread across most of the Consumer Price Index (CPI) basket rather than a few items.

What does the price evidence show?

1. Household expectations: The RBI’s household survey shows three month ahead expectations have jumped. Expectations shape the wages people ask for and the prices sellers set.
2. Limited embedding so far: The central bank’s own reading finds only limited signs that sellers are building supply side cost pressures into their pricing.
3. Food, fuel and weather: Global food prices are hardening, crude oil is dear, and a strengthening El Nino, a periodic Pacific warming that shifts rainfall, threatens the winter sown rabi crops.

How much more tightening does this justify?

1. The case for more: If pressures are spreading through wages and pricing behaviour, rates must rise further before expectations harden.
2. The case against: If the pressure is a run of supply shocks, higher rates cut demand and growth without touching the cause.
3. Deciding factors: Further tightening depends on how members read supply pressures, whether second-round effects take hold, and how growth and inflation move together.

Challenges

1. Shocks outside policy reach: Tightening against a crude oil shock buys price control at the cost of growth.
2. Expectations turn self-fulfilling: Households that expect dearer goods press for higher wages, so a survey reading can become actual inflation.
3. Transmission lags: A change in the repo rate, the rate at which the RBI lends to banks, reaches loans and demand only over several quarters, so a rise can bite after the shock passes.

Way Forward

1. State the exit test: The MPC should set out in its resolution what evidence would make it stop tightening, so firms can plan.
2. Supply measures with the Centre: The government should use buffer stock releases and duty changes on food staples, since the first round pressure is on supply.
3. Publish the expectations detail: The RBI should release the household survey’s city and group level readings, so the spread is visible.

Conclusion

Monetary policy has turned hawkish on a judgement that price pressures are no longer confined to supply, a judgement not all of the committee’s members share. Whether tightening goes further rests on evidence that wages and pricing behaviour are moving, not on the next inflation reading.

Key numbers

1. Spread of inflation: 37% of commodities in the CPI basket had inflation above 4% in August, against 20% in March (RBI Governor, MPC minutes).
2. Household expectations: Three month ahead expectations up 70 basis points to 9.9% (RBI household survey).
3. Energy price: Brent crude oil trading at around $115 a barrel.

Back2Basics: Monetary Policy Committee (MPC)

1. What it is: The six member committee that fixes the policy repo rate, set up under Section 45ZB of the Reserve Bank of India Act, 1934.
2. Composition: Three RBI members, including the Governor as chairperson, and three appointed by the Centre, with the Governor holding a casting vote.
3. The target: Under the Monetary Policy Framework Agreement of 2015 the target is 4% headline CPI inflation, with a tolerance band of two percentage points either side.
