Market Based Monetary Instruments

Bank Rate

The Bank Rate is the rate at which the RBI → Lends money to commercial banks → Without collateral
It is also called the discount rate.

Historical Role of Bank Rate

Earlier:

• Bank Rate was the primary policy rate
• Changes in Bank Rate influenced → Lending rates, Deposit rates, Overall credit conditions

However, with the introduction of → LAF, Repo rate, MSF → The Bank Rate lost its day-to-day operational role.

Current Role of Bank Rate

Today, the Bank Rate functions mainly as a → Penalty and Signalling Rate

It is used to calculate penal interest when banks fail to maintain → CRR/ SLR

Penal Structure

Penalties are imposed as → Bank Rate + 3%, or Bank Rate + 5%

Example

• Bank Rate = 4%
• Penalty = Bank Rate + 3%
• Penal interest = 7%

If a bank falls short of SLR:

• It must pay 7% interest on the shortfall
• This enforces regulatory discipline

Alignment with MSF

• The Bank Rate is aligned with the MSF rate
• Therefore → Whenever MSF changes, Bank Rate changes automatically

📌 UPSC Insight:
Bank Rate is now a reference rate, not a liquidity management tool.

Role in LAF	Centre	Discretionary	Ceiling	Floor	Outside LAF
Relation to Repo	Base rate	Below repo	Repo + 25 bps	Repo − 25 bps	= MSF
Main Use Today	Core policy signal	Secondary	Safety valve	Liquidity floor	Penalty computation

Open Market Operations

Open Market Operations (OMOs) refer to the buying and selling of government securities by RBI in the open market to regulate liquidity.

Unlike LAF:

• OMOs are outright transactions
• They have a longer-lasting impact on liquidity

OMO for Liquidity Injection

When RBI wants to increase money supply:

• It buys government securities from banks and PDs (Primary Dealers)
• Pays by crediting banks’ accounts
• Bank reserves increase
• Lending capacity expands

📌 Impact
More credit → higher investment & consumption → economic growth

OMO for Liquidity Absorption

When RBI wants to control inflation:

• It sells government securities
• Money flows from banks to RBI
• Bank reserves fall
• Lending capacity reduces

📌 Impact
Lower borrowing & spending → inflation cools down

OMOs vs LAF (Conceptual Distinction)

• LAF → Short-term, reversible liquidity management
• OMOs → Longer-term, durable liquidity impact

👉 UPSC often tests this difference.

Forex Swaps (Foreign Exchange Swaps)

What is a Forex Swap?

A forex swap is a two-leg transaction:

• One transaction happens today
• The reverse transaction happens on a pre-decided future date
• Exchange rate for both legs is pre-agreed

Forex swaps are conducted through RBI-announced auctions, in which commercial banks participate.

👉 Key idea: Temporary exchange of currencies to manage liquidity without permanently changing forex reserves.

Types of Forex Swaps

1. Sell/Buy Forex Swap

(Liquidity Absorption Tool)

Structure

• Sell leg (now): RBI sells foreign currency (e.g., USD) to banks
• Buy leg (future): RBI agrees to buy back the same foreign currency later

Purpose

• Absorb rupee liquidity
• Prevent rupee depreciation
• Manage inflationary pressure caused by excess liquidity

Example

• RBI sells USD 100 million at ₹80/USD
• Absorbs ₹8 billion from the banking system
• After one year, RBI buys back USD at ₹81/USD
• Re-injects ₹8.1 billion

📌 Insight: Liquidity absorption is temporary, unlike permanent sterilization.

2. Buy/Sell Forex Swap

(Liquidity Injection Tool)

Structure

• Buy leg (now): RBI buys foreign currency from banks
• Sell leg (future): RBI sells the same amount back later

Purpose

• Inject rupee liquidity
• Tackle liquidity crunch
• Smooth volatility in forex markets

Example

• RBI anticipates liquidity stress due to tax outflows
• Buys USD 100 million at ₹80/USD
• Injects ₹8 billion into the system
• After one year, RBI sells back USD at ₹79/USD
• Absorbs ₹7.9 billion

Why Forex Swaps Are Powerful

• Liquidity impact is time-bound
• Do not permanently alter RBI’s forex reserves
• Useful during:
  • Capital flow volatility
  • External shocks
  • Global monetary tightening/loosening cycles

📌 Note:
Forex swaps allow RBI to manage liquidity and exchange rate simultaneously without changing the policy rate.

Market Stabilization Scheme (MSS)

What is MSS?

The Market Stabilization Scheme (MSS) is a liquidity absorption tool used by RBI to sterilize excess liquidity, especially arising from large foreign exchange inflows.

• Introduced in 2004
• Used when forex inflows create → Excess rupee liquidity, Inflationary pressure, Undue appreciation of the rupee

Why MSS Was Needed

When RBI buys foreign currency to prevent rupee appreciation → It injects rupees into the banking system → This can fuel inflation

👉 MSS was designed to neutralize (sterilize) this excess liquidity.

How MSS Works

1. RBI issues Market Stabilization Bonds (MSBs)
2. These are government-backed securities
3. Sold via auction to banks and financial institutions
4. Money raised:
   • Not used for government spending
   • Parked in a separate MSS account

Important Features

• Interest cost borne by Government of India
• Principal repaid from the MSS account
• Usually short-term securities
• Purely a liquidity management tool

Indian Context Examples

Early 2000s

• Large capital inflows → Rupee appreciation pressure → MSS used extensively to absorb liquidity

Demonetisation (2016)

• Sudden surge in bank deposits → Massive excess liquidity → MSS deployed to mop up surplus funds

📌 UPSC Value Addition:
MSS is an exceptional tool, activated only during extraordinary liquidity situations.

MSS vs Open Market Operations (OMOs)

Aspect	OMOs	MSS
Nature	Buying/selling G-secs	Issuance of special bonds
Usage	Regular monetary tool	Exceptional, situation-specific
Liquidity Impact	Injection or absorption	Mainly absorption
Securities	Normal G-Secs, T-Bills	Market Stabilization Bonds
Fiscal Impact	Normal budget process	Interest borne by government, funds parked
