Repo and Reverse Repo: RBI's Liquidity Tools

Understanding Repo and Reverse Repo operations - how RBI manages liquidity, the LAF framework, policy rate transmission, and impact on interest rates.

6 min read Jan 15, 2025

Introduction: The Plumbing of Monetary Policy

“When the RBI changes the repo rate, it makes headlines. But understanding how repo actually works reveals the elegant mechanism through which monetary policy reaches the real economy.”

Repo and reverse repo are the primary tools through which the Reserve Bank of India manages liquidity in the banking system. These operations determine short-term interest rates and form the foundation of monetary policy transmission.


What is Repo?

Definition

Repo (Repurchase Agreement): A transaction where one party sells securities to another with an agreement to repurchase at a predetermined price on a future date.

In RBI Context: Banks sell government securities to RBI and get cash, agreeing to buy back at repo rate.

How Repo Works

StepAction
1Bank needs cash (liquidity)
2Bank sells G-secs to RBI
3RBI gives cash to bank
4At maturity, bank buys back G-secs
5Bank pays original amount + interest (repo rate)

Example

ParameterValue
G-secs sold₹100 crore
Repo rate6.5%
TenorOvernight
Interest₹100 cr × 6.5% × (1/365) = ₹1.78 lakh
Repurchase amount₹100.0178 crore

Why Banks Use Repo

ReasonBenefit
Short-term liquidityMeet daily obligations
CRR shortfallCover reserve requirements
Payment settlementClear large payments
Better rateCheaper than unsecured borrowing

What is Reverse Repo?

Definition

Reverse Repo: Banks lend money to RBI by buying securities with agreement that RBI will repurchase.

In RBI Context: Banks park excess cash with RBI, earning interest (reverse repo rate).

How Reverse Repo Works

StepAction
1Bank has excess cash
2Bank buys G-secs from RBI
3RBI takes cash from bank
4At maturity, RBI buys back G-secs
5Bank receives original amount + interest

Why Banks Use Reverse Repo

ReasonBenefit
Park surplus fundsEarn safe return
No credit riskRBI counterparty
LiquidityOvernight access
Capital efficiencyBetter than idle cash

Standing Deposit Facility (SDF)

Recent Addition (April 2022)

Replaced Reverse Repo as Floor:

FeatureDetails
PurposeAbsorb excess liquidity
CollateralNo collateral needed
RateSDF rate = Repo - 25 bps
IntroducedApril 2022

Why SDF Introduced

ReasonExplanation
No G-sec constraintRBI doesn’t need to sell G-secs
SimplerNo collateral management
FlexibilityCan absorb large liquidity

Marginal Standing Facility (MSF)

Definition

Emergency overnight borrowing window for banks at MSF rate.

Features

FeatureDetails
RateRepo rate + 25 bps
CollateralG-secs (including SLR)
Dip into SLRCan use 2% of SLR
PurposeEmergency liquidity

When Used

SituationAction
Tight liquidityBanks can’t get funds elsewhere
CRR pressureNeed to meet reserve
Penalty avoidanceCheaper than CRR penalty

LAF Corridor

Interest Rate Corridor

The Framework:

RateFunction
MSF RateCeiling (upper bound)
Repo RatePolicy rate (middle)
SDF RateFloor (lower bound)

Corridor Width: 50 bps (±25 bps from repo)

How Corridor Works

Overnight RateWhat Happens
Above MSFBanks borrow from MSF (ceiling)
Between MSF-RepoLAF repo borrowing
At RepoNormal operations
Between Repo-SDFSome excess liquidity
At SDFExcess parked with RBI (floor)

RBI’s Liquidity Operations

Liquidity Adjustment Facility (LAF)

Daily Operations:

OperationPurpose
RepoInject liquidity
Reverse Repo/SDFAbsorb liquidity

Timing: Daily at 10:00 AM and 2:30 PM

Variable Rate Operations

VRR (Variable Rate Repo):

  • Longer tenor (14 days, 28 days)
  • Auction-based rate
  • Manage durable liquidity

VRRR (Variable Rate Reverse Repo):

  • Absorb excess liquidity
  • Auction-based rate

Open Market Operations (OMO)

TypePurpose
OMO PurchaseInject durable liquidity
OMO SaleAbsorb durable liquidity

Difference from LAF: OMO = permanent; LAF = temporary


Liquidity Conditions

System Liquidity

Net Liquidity = Total deposits with RBI - Total borrowing from RBI

Repo Rate and Monetary Policy

Policy Rate

Repo rate is THE policy rate:

  • Announced by MPC every 2 months
  • Signals monetary policy stance
  • Benchmark for economy-wide rates

Transmission Mechanism

StageWhat Happens
1RBI changes repo rate
2Bank borrowing costs change
3Banks adjust deposit/lending rates
4Borrowers face new rates
5Consumption/investment affected
6Inflation/growth impacted

Repo in Non-RBI Context

Inter-Bank Repo

Banks with Banks:

  • Banks lend to each other
  • Using G-secs as collateral
  • CBLO market (now TREPS)

Corporate Repo

Tri-Party Repo (TREPS):

Repo in Liquid Funds

Reverse Repo/TREPS Exposure:

  • Safe component of liquid funds
  • Near risk-free
  • Lower yield, high safety

Key Takeaways

  1. Repo = borrowing – Banks borrow from RBI against G-secs
  2. Reverse repo = lending – Banks park money with RBI
  3. SDF is floor – Lower bound for overnight rates
  4. MSF is ceiling – Upper bound for overnight rates
  5. Corridor framework – Keeps rates within band
  6. Policy transmission – Repo rate affects all rates
  7. Watch liquidity – Determines actual market rates

Frequently Asked Questions

Q: Why is repo rate important for me? A: Repo rate influences your loan EMIs (especially floating rate) and FD returns. When repo rises, EMIs may increase and FD rates improve.

Q: What’s the difference between repo and MSF? A: Both involve borrowing from RBI against G-secs. Repo is normal facility; MSF is emergency at 25 bps higher. Banks use MSF when desperate.

Q: Why did RBI introduce SDF? A: With large liquidity surplus, RBI was running out of G-secs for reverse repo. SDF absorbs liquidity without needing collateral.

Q: How often does RBI change repo rate? A: MPC meets 6 times a year (every 2 months). Rate changes happen during these meetings, though not every meeting results in a change.

Q: Where can I track RBI’s liquidity operations? A: RBI website publishes daily Money Market Operations data. Shows LAF volumes, liquidity position, and rates.

Understanding repo and reverse repo is like understanding the engine of monetary policy—these operations determine the price of money in the economy and affect every financial decision from home loans to corporate bonds.
