Show answer

Answer: (B) an increase in the rate of interest

This is a basic supply-demand question applied to the money market.

Think of the interest rate as the 'price' of money.

If the supply of money remains constant but the demand for money increases (people want to hold more money for transactions or precautionary reasons), then money becomes relatively scarce.

Just like any other commodity — when demand exceeds supply, the price goes up.

Here, the 'price' of money is the interest rate, so it increases.

This is directly derived from the Liquidity Preference Theory.

Options (a), (c), and (d) do not logically follow from this scenario.

Why this was asked

Interest rate is the 'price' of money - when demand for money increases but supply stays constant, this price (interest rate) must rise.

This tests the core logic of Keynes' Liquidity Preference Theory, where interest rates adjust to balance money demand and supply in financial markets.

Money Market Equilibrium

Indian Economy supply of money demand for money rate of interest

Money Market Equilibrium: Supply, Demand & Interest Rate Determination

Must know

Interest rate is the 'price' of money in the money market

When money demand ↑ and supply constant → interest rates ↑

Money market follows basic supply-demand principles like any commodity market

Good to know

Based on Keynes' Liquidity Preference Theory

Core Concept

The money market works like any commodity market where interest rate acts as the price of money. When people want to hold more cash (increased demand) but the central bank keeps money supply unchanged, money becomes scarce and its 'price' (interest rate) rises.

Money Market Scenarios

Interest Rate Effect

Example

Question Scenario

Constant

Increases

Rises

Festive season - people need more cash

Expansionary Policy

Increases

Constant

Falls

RBI injects liquidity through OMO

Contractionary Policy

Decreases

Constant

Rises

RBI absorbs excess liquidity

Economic Growth

Constant

Increases

Rises

More transactions due to higher GDP

Question Analysis

The question tests understanding that interest rate = price of money

Option A (fall in prices) confuses money market with goods market - wrong direction

Option C (decrease in interest rate) gets the direction completely wrong

Option D (income/employment rise) is unrelated to immediate money market equilibrium

Exam traps

Trap: Confusing 'price level' with 'price of money' - they move in opposite directions

Trap: Thinking increased money demand automatically increases supply - supply is controlled by RBI

Trap: Mixing up short-term money market effects with long-term economic growth effects

Memory aid: Think of money like any scarce good - more demand + same supply = higher price (interest rate)

Liquidity Preference Theory

Indian Economy demand for money

Keynes' Liquidity Preference Theory: Why People Hold Money

Must know

Keynes identified 3 motives for holding money: transactions, precautionary, speculative

Liquidity preference = desire to hold money in liquid form rather than interest-earning assets

Money demand depends on income level and interest rates

Theory Foundation

John Maynard Keynes explained why people hold money despite it earning no interest. He called this liquidity preference - the desire to keep wealth in the most liquid form (cash) rather than bonds or other assets.

Three Motives for Holding Money

# Liquidity Preference
## Transactions Motive
- Daily purchases
- Business payments
- Salary payments
- Depends on income level
## Precautionary Motive
- Emergency fund
- Unexpected expenses
- Medical emergencies
- Also depends on income
## Speculative Motive
- Profit from bond price changes
- Interest rate expectations
- Inversely related to current interest rates
- Most volatile component

Relationship

UPSC Example

Stability

Transactions

Income Level

Positive

Higher GDP → more business transactions → more cash needed

Stable

Precautionary

Income Level

Positive

Richer people keep larger emergency funds

Fairly Stable

Speculative

Interest Rate

Negative

Low rates → people expect rates to rise → hold cash to buy bonds later

Volatile

UPSC Applications

RBI monetary policy directly impacts speculative demand - rate cuts increase money demand

Demonetization 2016 forced shift from cash (liquidity preference) to digital payments

Festival seasons increase transactions demand - RBI injects extra liquidity accordingly

Financial market volatility increases precautionary demand for cash

Exam traps

Trap: All three motives increase with income - only speculative motive is inversely related to interest rates

Trap: Higher interest rates reduce total money demand but through speculative motive only

Memory aid: TSP = Transactions, Speculation, Precaution - only Speculation varies with interest rates

RBI Money Supply Control

Indian Economy supply of money

RBI's Money Supply Control: Tools & Mechanisms

Must know

RBI controls money supply through repo rate, CRR, SLR, and OMO

Repo rate is the primary tool - rate at which RBI lends to banks

CRR & SLR directly control how much banks can lend

RBI's Role

The Reserve Bank of India has exclusive control over money supply in the economy. Unlike market forces that determine demand, supply is administratively controlled through various monetary policy instruments.

Recent Examples

COVID-19 response: RBI cut repo rate from 5.15% to 4% and reduced CRR to inject ₹3.74 lakh crore

Inflation targeting: RBI mandate to keep CPI inflation at 4% ± 2% guides money supply decisions

Demonetization impact: Currency in circulation dropped 20% temporarily, RBI had to manage liquidity carefully

Exam traps

Trap: Confusing RBI tools - CRR is with RBI, SLR is in government securities

Trap: Repo vs Reverse Repo direction - repo is RBI lending rate, reverse repo is RBI borrowing rate

Current affairs: UPSC often asks about recent changes in these rates - stay updated with RBI policy reviews
