NCERT Solutions for Class 12 Macroeconomics Chapter 3: Money and Banking
Introduction
Money and Banking is one of the most important chapters in Class 12 Macroeconomics. This chapter explores the concepts of money, functions of money, supply of money, and the role of banking in an economy. Understanding how the monetary system works is crucial for comprehending modern economic systems.
Overview of Chapter
The chapter begins by introducing the concept of money and discussing its evolution. It then moves on to explain the functions of money, the supply of money, and various measures of money supply. The banking system, including commercial banks and central banks, is also discussed in detail. The chapter concludes with an explanation of how the banking system creates money through the process of credit creation.
Key Concepts
Money
Money is anything that is generally accepted as a medium of exchange, measure of value, store of value, and standard for deferred payments. It facilitates economic transactions and helps in the smooth functioning of an economy.
Functions of Money
- Medium of exchange: Money facilitates the buying and selling of goods and services.
- Store of value: Money can be saved and retrieved in the future.
- Measure of value: Money serves as a common denominator to measure the value of goods and services.
- Standard of deferred payments: Money is used for settling future payments.
Evolution of Money
Money has evolved over time from commodity money to metallic money, paper money, and now to electronic money. This evolution reflects the changing needs of economies and advancements in technology.
For example, earlier people used cattle, grains, and other commodities as money. Later, metals like gold and silver were used. With the development of banking systems, paper money backed by reserves became common. Today, we also have digital currencies and electronic transactions.
Supply of Money
The supply of money refers to the total amount of money in circulation in an economy at a given point of time. In India, the Reserve Bank of India (RBI) is responsible for controlling the money supply.
Measures of Money Supply
In India, there are four measures of money supply:
- M1 = Currency + Demand Deposits + Other Deposits with RBI
- M2 = M1 + Post Office Savings Bank Deposits
- M3 = M1 + Time Deposits with Banks
- M4 = M3 + Post Office Savings Bank Deposits
| Measure | Components |
|---|---|
| M1 | Currency + Demand Deposits + Other Deposits with RBI |
| M2 | M1 + Post Office Savings Bank Deposits |
| M3 | M1 + Time Deposits with Banks |
| M4 | M3 + Post Office Savings Bank Deposits |
Banking System
Commercial Banks
Commercial banks are financial institutions that accept deposits from the public and lend money to borrowers. They play a crucial role in the economy by mobilizing savings and channeling them into productive investments.
Functions of Commercial Banks
Commercial banks perform various functions:
- Acceptance of deposits: They accept various types of deposits such as current accounts, savings accounts, and fixed deposits.
- Lending: They provide loans and advances to individuals and businesses.
- Credit creation: Through the process of credit creation, banks create money in the economy.
- Agency services: They act as agents for their customers, carrying out various services like collecting checks, making payments, etc.
- General utility services: They provide various general utility services like locker facilities, underwriting, etc.
Central Bank (Reserve Bank of India)
The central bank is the apex banking institution in a country. In India, the Reserve Bank of India serves as the central bank. It is responsible for regulating the monetary policy, issuing currency notes, controlling the credit supply, and acting as the banker to the government.
Functions of Central Bank
- Monopoly of note issue: The central bank has the exclusive authority to issue currency notes.
- Banker to the government: It acts as the banker, agent, and financial advisor to the government.
- Banker's bank: It acts as the bank of commercial banks, providing them with loans and advances.
- Controller of credit: It regulates the credit supply in the economy to maintain price stability.
- Custodian of foreign exchange reserves: It maintains foreign exchange reserves of the country.
Credit Creation by Banks
Process of Credit Creation
Credit creation is an important function of commercial banks. Banks create credit by maintaining only a fraction of their deposits as reserves and lending out the remaining amount. These loans then become deposits in other banks, leading to a multiplier effect. This process continues and results in the creation of multiple times the original deposit.
Credit Multiplier
The credit multiplier refers to the ratio of the total credit created to the initial deposit. It is calculated as:
Total Credit = Initial Deposit (1/Reserve Ratio)
The higher the reserve ratio, the lower the credit creation capacity, and vice versa.
For example, if the reserve ratio is 10%, and a bank receives an initial deposit of Rs. 1000, it will keep Rs. 100 as reserves and lend out Rs. 900. This Rs. 900 becomes a deposit in another bank, which again keeps 10% as reserves and lends out the remaining Rs. 810. This process continues, and eventually, the total credit created would be: Rs. 1000 (1/0.10) = Rs. 10,000.
NCERT Solutions
Question 1: What is money? Explain its functions.
Money is anything that is generally accepted as a medium of exchange for goods and services and in the repayment of debts. It serves as a measure of value, a store of value, and a standard for deferred payments.
Functions of money include:
- Medium of exchange: Money facilitates the buying and selling of goods and services.
- Store of value: Money can be saved and retrieved in the future.
- Measure of value: Money serves as a common denominator to measure the value of goods and services.
- Standard of deferred payments: Money is used for settling future payments.
Question 2: Explain the relationship between the reserve ratio and credit creation.
The reserve ratio and credit creation have an inverse relationship. The reserve ratio is the fraction of total deposits that banks are required to maintain as reserves. When the reserve ratio is high, banks have to keep a larger portion of deposits as reserves, reducing their ability to lend. This limits credit creation. Conversely, when the reserve ratio is low, banks can lend out a larger portion of deposits, leading to more extensive credit creation.
Question 3: What are the functions of a commercial bank?
Commercial banks perform the following functions:
- Acceptance of deposits: They accept various types of deposits such as current accounts, savings accounts, and fixed deposits.
- Lending: They provide loans and advances to individuals and businesses.
- Credit creation: Through the process of credit creation, banks create money in the economy.
- Agency services: They act as agents for their customers, carrying out various services like collecting checks, making payments, etc.
- General utility services: They provide various general utility services like locker facilities, underwriting, etc.
Question 4: How does a central bank control credit?
The central bank controls credit through various monetary policy instruments:
- Open market operations: Buying and selling of government securities to influence the money supply.
- Bank rate policy: Changing the rate at which the central bank lends to commercial banks.
- Variable reserve ratios: Adjusting the cash reserve ratio (CRR) and statutory liquidity ratio (SLR).
- Margin requirements: Changing the margin on loans given against securities.
- Moral suasion: Persuading commercial banks to follow certain credit policies.
Question 5: Distinguish between demand deposits and time deposits.
| Aspect | Demand Deposits | Time Deposits |
|---|---|---|
| Withdrawal | Can be withdrawn on demand | Can be withdrawn only after a specified period |
| Interest Rate | Generally lower interest rate | Higher interest rate |
| Examples | Current accounts, savings accounts | Fixed deposits, recurring deposits |
| Liquidity | More liquid | Less liquid |
