Monetary Policy Framework and Inflation

Prerequisites: Money Supply and the Banking System · National Income Accounting

The Hook: The Letter the RBI Had to Write

The Core Concept

Part 1: The framework

Objective. The Preamble of the RBI Act, as amended in 2016, says the primary objective of monetary policy is to maintain price stability while keeping in mind the objective of growth.

How India got here.

Key sections of the RBI Act (Chapter IIIF):

• Section 45ZA: the Central Government, in consultation with the RBI, determines the inflation target once every five years.
• Section 45ZB: constitution of the Monetary Policy Committee, which determines the policy rate required to achieve the target.
• Section 45ZN: if the RBI fails to meet the target, it must report to the Government the reasons, the remedial actions and the time needed. Failure means average inflation above the upper tolerance or below the lower tolerance for three consecutive quarters.

The Monetary Policy Committee

Part 2: The instruments

The RBI changes the price and quantity of money in the banking system. Most tools work through bank liquidity.

    A["MSF rate: ceiling, repo + 25 bp"] --> B["Policy repo rate: set by MPC"]
    B --> C["SDF rate: floor, repo - 25 bp"]
    B --> D["Weighted average call rate: operating target"]
    D --> E["Bank deposit and lending rates"]
    E --> F["Spending, investment and inflation"]

Qualitative (selective) tools: margin requirements on secured loans, credit rationing, selective credit controls, moral suasion and direct action.

Policy stance: the MPC also announces a stance, such as accommodative, neutral, or “withdrawal of accommodation”, which signals the likely direction of future rates.

Part 3: Transmission

A repo cut helps the economy only when banks cut their lending rates. India has tried successive lending-rate regimes to speed this up:

Part 4: Inflation

Inflation is a sustained rise in the general price level, which reduces the purchasing power of money.

Measuring inflation in India

Base years are revised periodically; check MoSPI and the Office of the Economic Adviser for the series currently in use.

Who gains and who loses from unexpected inflation: borrowers gain and lenders lose (the real value of debt falls); people on fixed incomes and pensioners lose; holders of cash lose. Inflation acts like a tax on money holdings.

Three relationships to remember:

• Fisher relation: real interest rate ≈ nominal interest rate − expected inflation.
• Quantity theory of money (Fisher’s equation of exchange): MV = PT. With velocity and output steady, faster money growth shows up as higher prices.
• Phillips curve: in the short run, lower unemployment tends to come with higher inflation; stagflation in the 1970s showed this trade-off is not stable.

Memory Anchors

MPC in numbers: “6-3-4-14”: 6 members, 3 external, 4-year term (and at least 4 meetings), minutes on day 14.

The corridor: “SDF sits on the floor, MSF hits the ceiling, repo lives in the middle.”

CRR vs SLR

Lending-rate regimes in order: “Bigger Banks Make Easy”: BPLR → Base rate → MCLR → External benchmark.

For Prelims

For Mains

• Dimensions: price stability vs growth; supply-side food inflation vs demand-side tools; transmission to bank rates; fiscal–monetary coordination; credibility and institutional independence; distributional effects of inflation on the poor.
• Keywords: nominal anchor, inflation expectations, flexible inflation targeting, policy corridor, liquidity, transmission lag, supply shocks, core inflation, fiscal dominance.
• Value-addition: the Urjit Patel Committee (2014) argued that a clear nominal anchor would anchor expectations. Because food and beverages form nearly half the 2012 CPI basket, supply shocks (monsoon failures, vegetable price spikes) push headline inflation in ways the repo rate cannot fix directly; this is why the framework is flexible, with a band and a growth objective.

Common Traps

In the News

• April 2022: the RBI introduced the Standing Deposit Facility as the floor of the liquidity adjustment facility corridor.
• November 2022: the RBI sent its first report to the Government under Section 45ZN after inflation stayed above 6% for three consecutive quarters.
• March 2021: the Government retained the 4% (2–6%) target for April 2021 to March 2026; check the current notification for the next five-year period → see Current Affairs.
