India's monetary policy framework

This is the topic an RBI interview panel is most likely to test, because it is the RBI's own core job. It also appears in ESI, in Finance & Management and in almost every Phase 1 current affairs set. The framework has a clear legal structure, a small set of instruments and a handful of recurring debates. Learn those three layers well and you can answer questions from a one-mark MCQ to a 15-mark evaluation.

How India got here

The shift happened because the multiple indicator approach, though flexible, gave no clear anchor for inflation expectations. After years of high inflation around 2010–13, a single, public, numerical target was meant to make policy predictable and accountable.

The legal architecture

The amended RBI Act, 1934 states that the primary objective of monetary policy is to maintain price stability while keeping in mind the objective of growth.

• Section 45ZA: the central government, in consultation with the RBI, sets the inflation target in terms of CPI, once every five years.
• Section 45ZB: constitutes the Monetary Policy Committee, which decides the policy rate needed to achieve the target.

The target and accountability

• Target: 4% CPI (Combined) inflation, with an upper tolerance of 6% and a lower tolerance of 2%.
• Periods: first notified for August 2016 to March 2021, then retained for April 2021 to March 2026.
• Failure: the RBI fails the target if average inflation stays above 6% or below 2% for any three consecutive quarters. It must then report to the government the reasons, the remedial actions it proposes and the time it expects to take to return to the target.

This was first triggered in 2022, when inflation stayed above 6% for the January–March, April–June and July–September quarters, driven by commodity prices after the war in Ukraine. The MPC held a special meeting and the RBI sent its report to the government in November 2022.

The Monetary Policy Committee

Each member's vote is public, so dissent is visible. That is deliberate: it makes the committee accountable and shows markets how views are shifting.

Operating procedure: the corridor

The MPC decides one number, the policy repo rate. The RBI's operations then try to keep the overnight money market rate close to it. The operating target is the weighted average call rate (WACR).

The liquidity adjustment facility (LAF) corridor sets the boundaries:

The SDF was introduced in April 2022 as the floor, replacing the fixed-rate reverse repo in that role. The Bank Rate is aligned with the MSF rate.

Illustration: if the repo rate were 5.50%, the SDF would be 5.25% and the MSF 5.75%. Since no bank would lend overnight below what the RBI pays or borrow above what the RBI charges, the call rate stays inside the 50-basis-point corridor.

Liquidity tools

• Variable rate repo (VRR) and reverse repo (VRRR) auctions to inject or absorb liquidity for fixed periods.
• Open market operations (OMOs): buying or selling government securities for durable liquidity.
• Cash reserve ratio (CRR): the share of deposits banks keep with the RBI (under Section 42 of the RBI Act).
• Statutory liquidity ratio (SLR): the share of deposits banks hold in liquid assets such as government securities (under the Banking Regulation Act); mainly prudential now.
• Foreign exchange swaps: buy/sell swaps can inject or absorb rupee liquidity.

Transmission: from the repo rate to your loan

Policy works through several channels: interest rates (loan, deposit and bond rates), credit (how much banks lend), the exchange rate, asset prices and expectations. Each works with a lag, often several quarters before the full effect on inflation.

Loan pricing has been reformed repeatedly to speed up the interest rate channel:

Under the external benchmark system, the rate must be reset at least once in three months. Illustration: a home loan priced at repo plus a spread of 2.75% would move from 8.25% to 8.00% after a 25-basis-point repo cut, at the next reset.

Transmission is still imperfect. Many deposits are fixed-rate for their term, small savings rates are set by the government, and banks compete for deposits. So lending rates can adjust faster than deposit rates.

The debates

Model answer outline (15 marks)

Question: Evaluate India's flexible inflation-targeting framework.

1. Opening: the 2016 amendment to the RBI Act; 4% CPI target with a 2–6% band; the MPC.
2. Features: statutory target, committee-based decisions, public votes and minutes, accountability report on failure.
3. Achievements: lower and more stable inflation in the early years; better-anchored expectations; transparency. Describe trends in words unless sure of numbers.
4. Challenges: supply shocks and food prices; the 2022 breach; imperfect transmission; external shocks through the rupee and capital flows.
5. The debates: headline versus core; target level and band.
6. Way forward: retain the framework's credibility; supply-side reforms by the government; better data and communication; faster transmission.
7. Conclusion: the framework has given India a credible anchor; its success depends on government supply-side action too.

Short model answer (10 marks)

Question: What is the liquidity adjustment facility corridor? How does it help the RBI keep the call money rate close to the repo rate?

The liquidity adjustment facility (LAF) is the set of windows through which the RBI injects or absorbs liquidity from banks. Its corridor has three parts: the policy repo rate in the middle; the Standing Deposit Facility as the floor, at 25 basis points below repo, where banks can park surplus funds without collateral; and the Marginal Standing Facility as the ceiling, at 25 basis points above repo, where banks can borrow overnight in emergencies.

The corridor works through arbitrage. No bank would lend in the call market below the SDF rate, because the RBI pays that rate risk-free. No bank would borrow above the MSF rate, because it can borrow from the RBI instead. So the weighted average call rate, the RBI's operating target, stays within the corridor.

Within the corridor, the RBI uses variable rate repo and reverse repo auctions to keep the call rate close to the repo rate. This makes the MPC's decision effective: a change in the repo rate moves the whole corridor, and through it money market, bond and loan rates.

Practice questions

1. How many members does the MPC have, and how many are appointed by the central government?
   • Six; three external members are appointed by the government.
2. What happens if MPC votes are tied?
   • The Governor has a second or casting vote.
3. Which facility forms the floor of the LAF corridor?
   • The Standing Deposit Facility.
4. Who sets the inflation target, and how often?
   • The central government, in consultation with the RBI, once every five years.
5. What is the RBI's operating target for monetary policy?
   • The weighted average call rate.
6. From when were new floating-rate retail and MSE loans required to be linked to an external benchmark?
   • 1 October 2019.

Common mistakes

• Writing the current repo rate from memory. State the rule, or take the figure from the latest statement.
• Calling the reverse repo the floor. The SDF has been the floor since April 2022.
• Saying the RBI sets the target alone. The government sets it in consultation with the RBI.
• Forgetting accountability. The failure-reporting rule is what gives the target teeth.

What to do next

• Read the latest MPC resolution and minutes; note the stance and each member's vote.
• Draw the corridor from memory with the current repo rate.
• Type the 15-mark answer above in 27 minutes.
• Revise with the inflation guide, and see the money market in the financial markets guide for how call and repo markets work.
