Answer: (B) Increase in the banking habit of the population

The correct answer is (B) — Increase in the banking habit of the population.

The money multiplier shows how much the total money supply increases for every rupee of base money.

When more people use banks (higher banking habit), more money gets deposited, banks can lend more, and those loans become new deposits elsewhere — creating a multiplier effect.

Increasing CRR (A) or SLR (C) would REDUCE the multiplier because banks must keep more money in reserve.

Population increase alone (D) doesn't change the multiplier.

Tip: More people banking = more deposits = more lending = higher money multiplier.

Why this was asked

The money multiplier determines how much total money supply increases when RBI injects one rupee of base money into the banking system.

Jan Dhan Yojana and digital payments push have increased banking penetration significantly, making the concept of banking habits affecting money supply practically relevant.

The question tests understanding that money multiplier depends on behavioral factors like banking habits, not just regulatory ratios like CRR and SLR.

Money Multiplier Concept

Indian Economy money multiplier

Money Multiplier: Formula, Mechanism & UPSC Applications

Quick Revision

Must know

Money multiplier = 1 ÷ (CRR + SLR + Currency-Deposit Ratio)

Higher banking habit reduces currency-deposit ratio → increases money multiplier

Higher CRR or SLR reduces money multiplier

Good to know

Shows how ₹1 of base money creates multiple rupees in total money supply

What is Money Multiplier

The money multiplier measures how much the total money supply expands when the central bank injects ₹1 of base money into the banking system. It works through fractional reserve banking — banks keep only a fraction of deposits as reserves and lend out the rest.

Factors Affecting Money Multiplier

Factor

Increase Causes

Why

UPSC Trap

Cash Reserve Ratio (CRR)

Multiplier decreases

Banks must keep more reserves, less lending

Students think more reserves = more multiplication

Statutory Liquidity Ratio (SLR)

Multiplier decreases

Banks must buy more govt securities, less lending

Similar confusion as CRR

Banking Habit

Multiplier increases

More deposits → lower currency-deposit ratio

Key to solving this PYQ

Currency-Deposit Ratio

Multiplier decreases

People hold more cash outside banks

Counter-intuitive for students

Question Analysis

This PYQ tests the inverse relationship between currency-deposit ratio and money multiplier. When banking habit increases, people deposit more and hold less cash — reducing the currency-deposit ratio and increasing the multiplier. Options A and C are direct traps because students confuse 'more reserves' with 'more multiplication'.

Common UPSC Mistakes

Trap: Higher CRR means more money in banks, so multiplier increases — Wrong! Higher CRR reduces lending capacity

Trap: Population increase automatically increases multiplier — Wrong! Only if new people use banks (banking habit matters)

Trap: SLR increases bank assets, so multiplier increases — Wrong! SLR reduces lendable funds

Memory: Money multiplier formula has these in denominator — so increasing CRR/SLR/Currency ratio reduces multiplier

CRR & SLR Banking Reserves

Indian Economy cash reserve ratio statutory liquidity ratio

CRR vs SLR: Definitions, Current Rates & Monetary Impact

Current Status

Must know

CRR: Currently 4% (varies with RBI policy)

SLR: Currently 18% (minimum 18%, can be higher)

Both are RBI tools to control money supply and liquidity

Good to know

Higher CRR/SLR = contractionary monetary policy

CRR vs SLR Comparison

Aspect

Cash Reserve Ratio (CRR)

Statutory Liquidity Ratio (SLR)

Definition

% of deposits kept with RBI in cash

% of deposits in liquid assets (cash + govt securities)

Where Kept

RBI account (cannot be used)

Bank's own vault (can be accessed)

Liquidity

Zero liquidity for banks

High liquidity — can sell govt securities

Interest Earned

No interest from RBI

Interest earned on govt securities

Primary Purpose

Control money supply

Ensure bank solvency and govt borrowing

Impact on Lending

Direct reduction in lendable funds

Indirect — diverts funds from private lending

How They Affect Money Multiplier

Increasing CRR: Banks must park more money with RBI → less lending → lower money multiplier

Increasing SLR: Banks must buy more govt bonds → less private lending → lower money multiplier

RBI uses both during inflation to reduce money supply and credit growth

Legal minimums: CRR can be 0% minimum, SLR cannot go below 18%

Frequency: RBI reviews both rates in monetary policy meetings every 2 months

UPSC Confusion Points

Trap: CRR money 'stays in banking system' so multiplier increases — Wrong! It's locked with RBI

Trap: SLR provides liquidity so multiplier increases — Wrong! It reduces lendable funds

Trap: Confusing CRR with repo rate — CRR is deposit ratio, repo is borrowing rate

Memory trick: Both CRR and SLR tie up bank money → less lending → lower multiplier

Currency-Deposit Ratio

Indian Economy banking habit population

Currency-Deposit Ratio: Impact on Money Multiplier & Banking Penetration

Key Relationships

Must know

Currency-Deposit Ratio = Cash with public ÷ Deposits with banks

Lower ratio = more banking habit = higher money multiplier

Good to know

India's ratio is higher than developed countries due to cash preference

Digital payments and financial inclusion reduce this ratio

Banking Habit Connection

Banking habit refers to people's tendency to use banks for saving, payments, and transactions instead of holding physical cash. When banking habit increases, the currency-deposit ratio falls because more money flows into the banking system rather than staying as cash in people's hands.

Factors Affecting Currency-Deposit Ratio

Impact on Money Multiplier

Examples

Improved banking habit

Decreases

Increases

More people open bank accounts

Digital payment adoption

Decreases

Increases

UPI, cards replace cash transactions

Financial inclusion

Decreases

Increases

Jan Dhan accounts, rural banking

Economic uncertainty

Increases

Decreases

People prefer cash during crisis

Higher denomination notes

Increases

Decreases

Easier to hold large cash amounts

Demonetization

Temporary decrease

Temporary increase

Forces money into banks initially

India-Specific Context

Post-demonetization: Currency-deposit ratio fell sharply in 2016-17, then gradually recovered

COVID-19 impact: Digital payments surged, reducing cash preference among urban population

Rural vs urban: Rural areas still have higher currency-deposit ratios due to limited banking access

Policy focus: Government promotes Digital India and JAM trinity to reduce cash dependence

Seasonal pattern: Ratio increases during festivals and harvest seasons when cash demand rises

Conceptual Mistakes

Trap: More population automatically means higher multiplier — Wrong! Depends on banking habits of new people

Trap: Currency-deposit ratio and money multiplier move in same direction — Wrong! They're inversely related

Trap: Demonetization permanently increased money multiplier — Wrong! Effect was temporary

Key insight: Population growth matters only if accompanied by improved banking penetration
