Monetary Policy

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

Monetary policy is the RBI’s framework for regulating money and credit to maintain price stability while supporting growth. Authority flows from the RBI Act, 1934 (Sections 22, 26, 28) and the Monetary Policy Framework Agreement (Feb 2015).

TermOne-line meaning
Repo RateSingle policy rate at which RBI lends short-term funds to banks against G-Secs
Reverse Repo / SDFRate at which RBI absorbs liquidity (SDF since Apr 2021, 25 bps below repo)
MSF RateRepo + 25 bps — banks’ overnight liquidity window (up to 2% of NDTL)
Bank RateLong-term lending rate under Sec 49, aligned to repo since Apr 2020
CRR / SLRCash with RBI / Statutory holdings by banks (Sec 42(1) and Sec 24)
MPC6-member statutory committee (3 RBI + 3 external) sets repo rate by majority
FITFlexible Inflation Targeting — CPI target 4% with ±2% band (2–6%)

Money Multiplier = 1 / CRR (CRR 4% ⇒ multiplier 25). Target operating rate is the WACR in the overnight call market.


🟡 Standard — Regular Study (2d–2mo)

Standard content for students with a few days to months.

Under Flexible Inflation Targeting (FIT), RBI’s primary mandate is CPI (Combined) inflation of 4% with a ±2% tolerance band (2%–6%). Growth is secondary. The Monetary Policy Framework Agreement (Feb 2015) between RBI and Government codified the target; the RBI (Amendment) Act, 2016 gave it statutory force. If inflation breaches the band for three consecutive quarters, RBI must submit a report to the Central Government explaining reasons and remedial action. The Government, in exceptional circumstances, can set a revised target for up to two years after consultation.

The Monetary Policy Committee (MPC)

The 6-member MPC decides the policy repo rate by majority vote. Composition: RBI Governor (chair, casting vote), RBI Deputy Governor in charge of monetary policy, one RBI officer nominated by the Central Board, and three external members nominated by the Central Government. The committee meets bi-monthly (at least four times a year), publishes a resolution, and releases minutes two weeks later disclosing each member’s vote and rationale.

Operating Framework — The LAF Corridor

The Liquidity Adjustment Facility (LAF) is the primary operating instrument. The repo rate is the single policy rate. The corridor:

  • Upper bound = MSF Rate (repo + 25 bps), available without bidding, collateral: SLR-eligible securities.
  • Lower bound = SDF Rate (repo − 25 bps, variable since Apr 2021), introduced as an uncollateralised absorption tool to replace the fixed Reverse Repo as floor.

Banks anchor the Weighted Average Call Rate (WACR) to the repo rate; WACR is the operating target.

Quantitative vs Qualitative Tools

Quantitative instruments control volume: CRR (cash reserve with RBI, no interest paid since 2007), SLR (held by banks in cash, gold, govt-approved securities), Open Market Operations (OMO), Market Stabilisation Scheme (MSS), and LCR under Basel III.

Qualitative tools change composition or direction: margin requirements, credit ceilings, priority-sector lending, moral suasion, and administrative guidance.

Transmission Mechanism

Repo rate → bank lending/deposit rates → credit growth → aggregate demand → inflation/output. The real policy rate ≈ nominal repo − expected inflation (Fisher approximation), guiding the MPC’s stance: Accommodative (easing), Neutral, or Withdrawal of Accommodation (replaced “Calibrated Tightening” from the October 2022 MPC resolution).


🔴 Extended — Deep Study (3mo+)

Comprehensive coverage for students on a longer study timeline.

Worked Numerical — Money Multiplier in Action

Suppose CRR is 4%. Money multiplier m = 1 / 0.04 = 25. Initial fresh primary deposit of ₹1,000 cr with the banking system expands M1 by ₹25,000 cr under full lending. If RBI hikes CRR from 4% to 5%, m collapses to 20, contracting potential M1 by ~20% for the same base. Likewise, an OMO purchase injecting ₹10,000 cr reserves raises M1 by 10,000 × 25 = ₹2.5 lakh cr (ΔMS = ΔReserves × 1/CRR). Always keep units in ₹ crore and CRR in decimal form.

Edge Cases and Examiner Traps

  • SDF ≠ Reverse Repo. The Standing Deposit Facility (April 2021) is uncollateralised and 25 bps below repo. Pre-2021 answer keys calling reverse repo the corridor floor are now obsolete.
  • MSF vs Bank Rate. MSF is overnight, 2% of NDTL, at repo + 25 bps; the Bank Rate is the long-term lending signal under Section 49 of the RBI Act, currently aligned with the repo rate.
  • WPI is out. FIT targets CPI-Combined (not WPI or GDP deflator); a strong distractor in MCQs.
  • Governor ≠ Sole Authority. Since the 2016 amendment, only the MPC sets the repo rate. The Governor chairs and casts a tie-breaking vote.
  • Stance vocabulary. Memorise the chronology: Accommodative → Neutral → Calibrated Tightening (2018) → Withdrawal of Accommodation (Oct 2022 onward).

Adjacent Connections

  • Fiscal–Monetary Coordination — beyond the 2015 Framework Agreement, coordination occurs through the GDP deflator and G-Sec yields, since heavy government borrowing raises yields and crowds out private credit (the “twin balance sheet” problem).
  • MPC reporting to Parliament ties into Section 7 of the RBI Act, an unusual provision where the Centre can consult and even direct RBI on public-interest matters.
  • LCR under Basel III influences the corridor by altering banks’ willingness to use MSF/SDF facilities.

Practice Prompts

  1. “Identify the uncollateralised liquidity absorption tool introduced by RBI in April 2021, its rate spread relative to repo, and why it replaced the fixed reverse repo.”
  2. “CRR rises from 4% to 5.5%. Compute the change in money multiplier and explain its likely impact on M1, assuming primary deposit expansion remains constant.”
