Monetary Policy of RBI: CRR, SLR, Repo Rate & All Tools Explained for UPSC

RBI's monetary policy framework changed fundamentally in 2016 when India adopted flexible inflation targeting. Before 2016, the RBI used multiple indicators — money supply, credit growth, exchange rate — with no single anchor. After 2016, there is one clear objective: keep CPI inflation at 4%, with a tolerance band of +/- 2% (i.e., between 2% and 6%).

This is not academic trivia. UPSC Prelims has asked about MPC composition, the inflation target, and specific tools in nearly every exam since 2017. GS-III Mains regularly tests the transmission mechanism and the effectiveness of monetary policy.

The Monetary Policy Committee (MPC) now drives all rate decisions. Understanding who sits on it, how they vote, and what tools they control is non-negotiable for UPSC preparation.

The Monetary Policy Committee (MPC)

The MPC was constituted under Section 45ZB of the RBI Act, 1934 (amended by the Finance Act, 2016). It has 6 members:

RBI side (3 members):

1. RBI Governor (Chairperson, with casting vote in case of a tie)
2. Deputy Governor in charge of monetary policy
3. One officer of RBI nominated by the Central Board

Government side (3 members): 4-6. Three members appointed by the Central Government from a search-cum-selection committee

Each member has one vote. The Governor's casting vote means the RBI effectively controls outcomes in a 3-3 split. The MPC meets at least 4 times a year (currently meets 6 times — every 2 months). Decisions are by majority vote, and individual votes are published.

Common student mistake: Writing that the Finance Minister is on the MPC. The Finance Minister has no seat. The government-appointed members are academics/experts selected through a committee, not bureaucrats or politicians.

The MPC's mandate is price stability while keeping growth in mind. The inflation target agreement between the Government and RBI specifies: if CPI inflation stays above 6% or below 2% for three consecutive quarters, the MPC must write a report to the Government explaining why and proposing remedial actions. This "failure clause" has not been triggered yet, though inflation breached 6% for multiple months in 2022.

Quantitative Tools: The Rate Framework

Repo Rate

The Repo Rate (Repurchase Rate) is the rate at which the RBI lends short-term money to commercial banks against government securities as collateral. It is the primary policy rate — when you hear "RBI cut rates" or "RBI hiked rates," this is the repo rate.

Current Repo Rate: 6.25% (as of February 2025, after a 25 bps cut from 6.50%)

Mechanism: When RBI raises the repo rate, borrowing becomes costlier for banks. Banks raise lending rates. Loans become expensive. Spending and investment fall. Demand drops. Inflation cools. The reverse happens when RBI cuts the repo rate.

The repo rate operates through the Liquidity Adjustment Facility (LAF), conducted daily through auctions.

Standing Deposit Facility (SDF) — Replaced Reverse Repo

The SDF was introduced in April 2022 as the new floor of the LAF corridor. Banks deposit surplus funds with RBI at the SDF rate. Unlike the old reverse repo, SDF does not require government securities as collateral — the RBI simply accepts deposits.

Current SDF Rate: 6.00% (Repo Rate minus 25 basis points)

Why the change? The reverse repo required the RBI to hold government securities to accept deposits. The SDF gives RBI more flexibility to absorb liquidity without being constrained by its securities portfolio. The reverse repo still exists technically but is no longer the primary absorption tool.

Common student mistake: Still writing "Reverse Repo Rate" as the floor of the LAF corridor. Since April 2022, the SDF rate is the effective floor. Update your notes.

Marginal Standing Facility (MSF)

MSF Rate = Repo Rate + 25 basis points = 6.50%

Banks can borrow overnight from RBI under MSF by dipping into their SLR portfolio (up to a specified percentage). MSF is an emergency window — costlier than repo, available when banks face acute short-term liquidity shortage.

The MSF rate forms the ceiling of the LAF corridor. The corridor is: SDF (floor) — Repo (middle) — MSF (ceiling), with a 50 bps width.

Bank Rate

Current Bank Rate: 6.50% (aligned with MSF rate)

The Bank Rate is the rate at which RBI lends long-term funds to banks without collateral. In practice, it is now aligned with the MSF rate and has limited independent significance. It is used for penalty calculations (penalty on CRR/SLR shortfall is charged at Bank Rate + margin).

Cash Reserve Ratio (CRR)

Current CRR: 4.00%

Every scheduled commercial bank must maintain a certain percentage of its Net Demand and Time Liabilities (NDTL) as cash with the RBI. This cash earns no interest.

CRR is the most direct liquidity tool. When RBI raises CRR from 4% to 4.5%, banks must park more money with RBI. Less money is available for lending. Credit contracts. When RBI cuts CRR, the opposite happens — money is released into the system.

Key facts for UPSC:

• CRR applies to all scheduled commercial banks (including foreign banks operating in India)
• RBI can set CRR between 0% and 15% without referring to the Government (as per RBI Act amendments)
• CRR changes do not require MPC approval — it is an RBI administrative decision
• CRR deposits earn zero interest

Statutory Liquidity Ratio (SLR)

Current SLR: 18.00%

Banks must maintain a specified percentage of NDTL in liquid assets — government securities (G-Secs), cash, and gold. Unlike CRR (which sits idle with RBI), SLR investments in G-Secs earn interest.

SLR serves two purposes: ensuring bank solvency (liquid assets as backup) and creating a captive market for government borrowing (banks are forced to buy G-Secs).

RBI can set SLR between 0% and 40%. Over the years, SLR has been progressively reduced from over 30% in the 1990s to the current 18%.

Open Market Operations (OMOs)

RBI buys or sells government securities in the open market to inject or absorb liquidity.

• RBI buys G-Secs → pays banks → money enters the system → liquidity increases
• RBI sells G-Secs → banks pay RBI → money exits the system → liquidity decreases

OMOs are a permanent liquidity tool — unlike repo (temporary, overnight/short-term), OMOs change the monetary base durably.

Long-Term Repo Operations (LTROs) — introduced in 2020 — are repo operations with 1-3 year maturity, providing longer-term liquidity at the repo rate.

The Complete Rate and Tool Table

Qualitative Tools: The Other Side of Monetary Policy

Quantitative tools adjust the volume of money. Qualitative tools control the direction of credit.

Margin Requirements: RBI can change the margin (down payment) required for loans against specific assets. If gold prices are rising due to speculation, RBI can raise the margin for gold loans from 25% to 40%, discouraging speculative borrowing.

Credit Rationing: RBI can set sector-specific lending limits. Priority sector lending norms (40% of adjusted net bank credit to agriculture, MSMEs, education, housing) are a form of credit direction.

Moral Suasion: RBI Governor‘s statements, advisories, and informal guidance to banks. When RBI publicly asks banks to pass on rate cuts to consumers, that is moral suasion. It has no legal force but carries institutional weight.

Direct Action: RBI can refuse to rediscount bills, charge penal interest, or ultimately cancel a bank's license. This is the nuclear option — rarely used against large banks but applied to cooperative banks and small finance institutions.

The Transmission Mechanism: How Rate Changes Reach You

This is where UPSC Mains expects depth. The repo rate changing from 6.50% to 6.25% does not automatically make your home loan cheaper. The chain works like this:

RBI cuts repo rate → banks' cost of borrowing from RBI falls → banks should cut deposit rates and lending rates → cheaper loans → more borrowing → more spending → economic activity increases

The problem is transmission lag. Banks have been historically slow to pass on RBI rate cuts to borrowers.

MCLR to EBLR: The Transmission Fix

Before 2016, banks used Base Rate — an opaque internal calculation. RBI replaced it with MCLR (Marginal Cost of Funds Based Lending Rate) in April 2016. MCLR was better but still allowed banks to delay transmission.

In October 2019, RBI mandated that all new floating-rate retail loans (home, auto, MSME, personal) must be linked to an External Benchmark — the repo rate, 3-month T-bill rate, 6-month T-bill rate, or any other benchmark published by FBIL. Most banks chose the repo rate.

This External Benchmark Linked Lending Rate (EBLR) system means rate changes now flow through within 1-3 months for new loans — a massive improvement over the old system where transmission took 6-12 months.

Common student mistake: Writing that all loans are now linked to EBLR. Only new floating-rate retail and MSME loans are mandatorily EBLR-linked. Old loans on MCLR or Base Rate continue on their original benchmarks unless borrowers switch. Corporate loans are not mandatorily EBLR-linked.

Inflation Targeting Framework: The 2016 Shift

Before 2016, the RBI targeted multiple objectives — inflation, growth, exchange rate stability, financial stability — with no clear hierarchy. The Urjit Patel Committee (2014) recommended adopting CPI-based inflation targeting, which was formally implemented through the RBI Act amendment in 2016.

Key parameters:

• Target: CPI inflation at 4%
• Upper tolerance: 6%
• Lower tolerance: 2%
• Review period: Every 5 years (first period 2016-2021, renewed for 2021-2026)
• Failure clause: If inflation stays outside the 2-6% band for 3 consecutive quarters, RBI must explain to the Government

Why CPI and not WPI? CPI (Consumer Price Index) captures what consumers actually pay. WPI (Wholesale Price Index) captures producer prices and includes items like crude oil and industrial metals that consumers do not buy directly. Since monetary policy aims to manage aggregate demand through consumer behavior, CPI is the appropriate anchor.

India uses CPI (Combined) — base year 2012 — which covers rural and urban India, compiled by the NSO.

Monetary Policy Stances

The MPC announces not just rates but a stance that signals future direction:

• Accommodative: Indicates willingness to cut rates. Will not raise rates. Focus on supporting growth.
• Neutral: Open to moving in either direction based on data. No bias.
• Tightening/Hawkish: Rates may increase. Focus on controlling inflation.
• Withdrawal of Accommodation: Transitional stance — no longer accommodative, moving toward neutral. Used during 2022-23 as MPC shifted from COVID-era easy money.

The stance matters as much as the rate itself. A repo rate hold with a change in stance from "neutral" to "accommodative" signals that cuts are coming — and markets and banks adjust in anticipation.

How UPSC Tests Monetary Policy

Prelims pattern: "Which of the following is/are quantitative tools of RBI?" or "Consider the following statements about MPC" — factual recall questions.

Mains GS-III pattern: “Examine the effectiveness of RBI’s inflation targeting framework in the post-COVID period.” Or: “Discuss the challenges of monetary policy transmission in India.”

The scoring answer structure for Mains:

1. Define the concept/tool
2. Explain the mechanism with current numbers
3. Identify one limitation or controversy
4. Connect to India's current economic situation
5. Suggest one reform or improvement

For example, on transmission: "The EBLR system has improved transmission for new retail loans, but the Rs 40+ lakh crore stock of old MCLR-linked loans still shows weak transmission. A time-bound migration framework could address this structural gap."

What Counts as Money: Legal Tender and the Supply Aggregates (M0–M3)

Before the RBI can manage money, you have to know what “money” legally is. Only fiat money — the currency notes and coins issued under the authority of the state — is legal tender that a creditor must accept to settle a debt. The everyday instruments people treat as money are not legal tender: demand deposits (the balance in your savings or current account) and cheques drawn on those accounts are payment instruments a creditor can lawfully refuse. They are convenient, but acceptance is by consent, not by law. This is exactly the distinction GPSC 2026 tested — fiat money qualifies as legal tender, deposits and cheques do not.

Those accepted forms are then bundled into the RBI’s money-supply aggregates, ordered by liquidity. M0 (reserve money or high-powered money) is currency in circulation plus bankers’ deposits with the RBI and other deposits — the monetary base the central bank directly controls. M1 (narrow money) is currency with the public plus demand deposits plus other deposits with the RBI. M2 adds savings deposits held at post offices. M3 (broad money), the headline figure the RBI tracks, is M1 plus time deposits with banks, while M4 further adds total post-office deposits. Each step trades immediate spendability for a wider definition of money.

This foundation also explains a bank run (a related GPSC trap): because most deposits are not held as cash but lent out, a sudden rush of depositors withdrawing at once can drain a solvent bank’s liquidity and push it toward failure — which is why the RBI’s liquidity tools, deposit insurance, and reserve ratios exist in the first place.
