RBI's Monetary Policy: Repo, CRR, SLR, and What Actually Moves Inflation

May 28, 2026
8 min read

In June 2022, the RBI held an emergency off-cycle Monetary Policy Committee meeting and raised the repo rate by 40 basis points. It was the first off-cycle rate action since 2020's COVID cut. The trigger: inflation at 7.8%, well above the upper tolerance band of 6%. Over the next 18 months, the MPC raised the repo rate 250 basis points — from 4% to 6.5%. Understanding why these decisions were made, what instruments were used, and how they affect you is the core of monetary policy for UPSC.


[TOPIC CLASSIFICATION]

Topic type: Monetary Economics / RBI / Economy PYQ frequency: Very High. Every year in Prelims; Mains GS 3 standard topic. Exam stage relevance: Prelims + Mains Primary GS Paper: GS 3 (Indian Economy)


[EXAMINER REASONING]

  1. Trap: Confusing what repo and reverse repo are from the bank's perspective. Repo = RBI lends to banks (banks REPO their securities). Reverse Repo = RBI borrows from banks (banks park excess funds with RBI). Repo rate is higher; reverse repo rate is lower.

  2. Most confused: CRR vs SLR. Both are reserve requirements. CRR must be kept with RBI in cash. SLR must be maintained in liquid assets (government securities, gold, cash). CRR earns no interest; SLR assets earn interest.

  3. Key anchor: The inflation targeting framework (amended RBI Act, 2016). 4% target ±2% band (2–6%). If CPI inflation exceeds 6% for three consecutive quarters, RBI must explain to government in writing. This framework formalised MPC's mandate.

  4. Current affairs hook: In FY 2023–24, after 250bps of rate hikes, the MPC paused rates at 6.5% for 6+ meetings. By 2024–25, inflation fell below 4%, and the MPC began cutting rates. The monetary policy stance shifted from 'withdrawal of accommodation' to 'neutral'.

  5. Mains hinge: "India's inflation targeting framework has improved monetary policy credibility but constrained RBI's developmental role." Evaluate.


Core Concept

The Liquidity Adjustment Facility (LAF) — the corridor

The RBI manages short-term liquidity through a corridor:

  • Repo Rate: RBI lends overnight to banks against government securities. Banks pay repo rate. Currently 6.5% (as of mid-2024). This is the policy rate — the primary signal.
  • Reverse Repo Rate: RBI borrows overnight from banks (banks park surplus). Banks receive reverse repo rate. Typically 35 bps below repo = Standing Deposit Facility (SDF) replaced the fixed-rate reverse repo in 2022.
  • Marginal Standing Facility (MSF): Emergency window — banks borrow from RBI at MSF rate (repo + 25 bps). Borrowing against SLR securities (even below minimum SLR requirement).

Critical Minerals and India's Strategy: Self-Reliance in a Resource Race

India identified 30 critical minerals in 2023 — including lithium, cobalt, nickel, graphite, and rare earth elements. Global demand for critical minerals is projected to increase 3-5 times by 2030. India imports 100% of lithium and cobalt. The Critical Mineral Mission (2024, ₹24,000 Cr) aims to change this.

MSP Legal Guarantee & Farmer Protests: The Agricultural Pricing Debate

The 2020-21 farmer protests against three farm laws led to their repeal — but the core demand for a legal guarantee of MSP (Minimum Support Price) continues. The government has not accepted the demand. MSP covers 23 crops but only 6% of farmers sell at MSP. The legal guarantee question divides economists and policymakers.

GST: Structure, Council, and What UPSC Keeps Asking

GST replaced 17 taxes and 23 cesses with one destination-based tax from July 1, 2017. This note covers the dual GST structure (CGST/SGST/IGST/UTGST), the GST Council's composition and voting, the five rate slabs, HSN codes, input tax credit, the compensation cess controversy, and why the 101st Constitutional Amendment is the legal backbone of the entire system.

  • Standing Deposit Facility (SDF): Introduced 2022. Replaced fixed-rate reverse repo as the floor. Banks can park unlimited funds with RBI at SDF rate (repo − 25 bps).
  • So the LAF corridor = SDF (floor) to MSF (ceiling), with Repo Rate in the middle.


    Reserve Requirements

    • Cash Reserve Ratio (CRR): Percentage of a bank's Net Demand and Time Liabilities (NDTL) that must be kept with RBI in cash. Currently 4%. Earns NO interest. Directly affects money supply.
    • Statutory Liquidity Ratio (SLR): Percentage of NDTL that banks must maintain in liquid assets: government/approved securities, cash, or gold. Currently 18%. Earns interest (unlike CRR). Ensures banks always have liquidity.

    Open Market Operations (OMO)

    RBI buys or sells government securities in the open market to manage liquidity:

    • OMO Purchase (buying G-secs): Injects liquidity into the system. Bank credit expands.
    • OMO Sale (selling G-secs): Absorbs liquidity from the system. Credit tightens.

    Monetary Policy Committee (MPC)

    Constituted under RBI Act 1934 (amended 2016). Fixes the repo rate (policy rate).

    Composition (6 members):

    • RBI Governor (Chairperson)
    • 2 RBI Deputy Governors / officials nominated by RBI Board
    • 3 external members appointed by Central Government (Ministry of Finance)

    Voting: Simple majority; Governor has casting vote in case of tie. Meetings: At least 4 times a year (usually 6 — every 2 months). Mandate: Maintain CPI inflation at 4% with ±2% band (2–6%). Accountability: If inflation stays outside band for 3 consecutive quarters, MPC must write to government explaining why and what remedial action is planned.


    Key Facts

    • current repo rate: 6.5% (paused since Feb 2023; first cut cycle began mid-2024)
    • inflation target: 4% ±2% (2–6% band), CPI-based
    • MPC composition: 3 RBI + 3 government appointees; Governor chairs with casting vote
    • CRR: 4% of NDTL; kept with RBI in cash; no interest
    • SLR: 18% of NDTL; liquid assets (G-secs, gold, cash); earns interest
    • SDF introduced: April 2022 (replaced fixed-rate reverse repo as floor)
    • OMO: RBI open market bond operations to manage system liquidity
    • monetary policy stance categories: Accommodative (easy), Neutral, Withdrawal of Accommodation, Calibrated Tightening

    Statement Elimination Guide

    Correct: "When RBI increases the repo rate, borrowing by banks from RBI becomes costlier, which leads to higher lending rates and lower credit offtake, helping to cool inflation." False: "Increasing repo rate directly controls government spending." Trap: "Reverse repo rate is higher than repo rate." (False. Repo rate is always higher. Banks borrow at repo (higher), park funds at reverse repo/SDF (lower).)

    Correct: "CRR is maintained with RBI in cash and earns no interest. SLR is maintained in liquid assets including government securities, which earn interest." False: "Both CRR and SLR are maintained with RBI and earn the repo rate of interest." Trap: "Reducing CRR increases money supply." (Correct — it is NOT a trap. This is the mechanism: lower CRR → banks keep less with RBI → more to lend → money supply expands.)

    Correct: "The MPC has 6 members: 3 from RBI and 3 external experts appointed by the Central Government." False: "All MPC members are appointed by the RBI Board."


    Current Affairs Hook

    By early 2025, the RBI's MPC shifted its policy stance from 'withdrawal of accommodation' (tightening bias) to 'neutral' as food inflation began moderating and core inflation fell below 4%. The February 2025 MPC meeting cut the repo rate by 25 bps for the first time since 2020 — signalling the beginning of an easing cycle. However, US Fed's rate path, rupee depreciation pressure, and food price volatility from erratic monsoons remain key risks.

    The SDF (Standing Deposit Facility) introduced in April 2022 was a significant reform — it gives RBI an uncollateralised absorption window, unlike reverse repo (which required government securities as collateral). This improved RBI's liquidity management flexibility considerably.


    Common Mistakes

    1. "Repo rate is the rate at which RBI borrows from banks": No. Repo = RBI LENDS to banks. Reverse repo/SDF = RBI borrows from banks.
    2. "SLR is maintained with RBI in cash": No. SLR is maintained in the bank's own books in liquid assets (G-secs, gold, cash). CRR is maintained WITH RBI.
    3. "OMO purchase increases interest rates": No. OMO purchase injects liquidity, which generally REDUCES short-term rates by easing supply.
    4. "MPC decision requires unanimous agreement": No. Simple majority. Governor has casting vote in case of tie.
    5. "CPI target is 4% with no tolerance band": No. 4% ±2% — the band is 2–6%. Breach of 6% for 3 consecutive quarters triggers accountability to government.

    Revision Snapshot

    RBI's monetary policy uses the LAF corridor: SDF (floor = repo − 25bps) → Repo Rate (policy rate, currently 6.5%) → MSF (ceiling = repo + 25bps). CRR (4% NDTL): kept with RBI in cash, no interest, controls money supply. SLR (18% NDTL): liquid assets, earns interest, ensures bank liquidity. OMO: RBI buys G-secs = liquidity injection; sells = absorption. MPC: 6 members (3 RBI, 3 government appointees), simple majority, Governor casting vote; meets 6×/year; inflation target 4% ±2% CPI; if >6% for 3Q, must write to government. SDF introduced April 2022 (replaced fixed-rate reverse repo as floor). 2022–23: 250bps hike cycle. 2025: easing cycle begins.
