NCERT Explained: Class XII Macroeconomics, Chapter 3 - Money and Banking

Introduction to the Topic

Imagine a world without money. How would you buy your favourite book, pay for a movie ticket, or even get a haircut? You would have to trade something you own for the service or good you want. This system of direct exchange, known as the barter system, was the foundation of early human commerce. However, it was riddled with complexities and inefficiencies. This chapter from your Class XII Macroeconomics textbook, "Money and Banking," takes us on a fascinating journey from the clunky barter system to the sophisticated financial world we live in today. It unravels the very essence of money—what it is, why we need it, and how it functions. Furthermore, it delves into the backbone of a modern economy: the banking system. We will explore the roles of commercial banks, their almost magical ability to 'create' money, and the supreme authority of the Central Bank, the Reserve Bank of India (RBI), which acts as the guardian of the nation's financial stability. Understanding money and banking is not just an academic exercise; it's about understanding the pulse of the economy, the forces that dictate prices, and the policies that shape our financial lives. So, let's dive in and demystify the concepts that keep the wheels of our economy turning.

Key Concepts Explained

The Barter System and its Drawbacks: Life Before Money

Before the invention of money, societies relied on the barter system. Barter is the direct exchange of goods and services for other goods and services. If a farmer who grew wheat wanted a pair of shoes, he had to find a shoemaker who not only had an extra pair of shoes but was also in need of wheat. This fundamental problem highlights the biggest drawback of the barter system.

The Problem of Double Coincidence of Wants:

This is the cornerstone issue of barter. It means that for an exchange to occur, two individuals must each have a good or service that the other desires. The wheat farmer needing shoes must find a shoemaker wanting wheat. The chances of this mutual desire occurring simultaneously are incredibly low, making transactions difficult, time-consuming, and highly restrictive for economic growth.

Beyond this primary hurdle, the barter system suffered from several other significant limitations:

• Lack of a Common Measure of Value (Unit of Account): How do you determine the value of a cow in terms of sacks of rice or pairs of shoes? Without a common unit of account, every good had to be valued against every other good. This created a chaotic and unmanageable system of millions of exchange ratios. For example, if there are 1000 different goods, you would need to remember nearly half a million exchange rates! Money provides a simple, universal yardstick to measure and compare the value of all goods and services.
• Difficulty in Storing Wealth (Store of Value): How could the farmer store his wealth? He could store wheat, but it is perishable and would rot over time. Storing live animals is costly and risky. Wealth in the form of physical commodities is often bulky, difficult to store, and can lose value. Money, on the other hand, is a much more convenient way to store purchasing power for future use.
• Problem of Divisibility: Imagine you have a horse and you want to buy a small item like a loaf of bread. You cannot divide the horse into smaller pieces without destroying its value. This lack of divisibility for many goods made small transactions nearly impossible under the barter system.
• Absence of a Standard for Deferred Payments: The barter system made it extremely difficult to engage in contracts or credit transactions that involved future payments. If you borrowed a bag of wheat today, how would you repay it a year later? The quality of the wheat might differ, or its value relative to other goods might have changed drastically. This uncertainty hindered lending and borrowing, which are crucial for investment and economic development.

The Evolution and Functions of Money: A Revolutionary Invention

The inconveniences of the barter system led to the evolution of money. Initially, various commodities like salt, shells, cattle, and grains were used as 'commodity money'. Over time, precious metals like gold and silver became the preferred medium of exchange due to their durability, divisibility, and portability. This eventually led to the modern form of money, including paper currency and coins (fiat money) and digital transactions.

So, what exactly is money? Money is defined as anything that is generally accepted as a medium of exchange and simultaneously acts as a measure, store of value, and standard for deferred payments. Its value comes from the trust and acceptance it commands within a society. Let's break down its crucial functions.

Primary Functions of Money

• Medium of Exchange: This is the most important function of money. It eliminates the need for a double coincidence of wants. Money acts as an intermediary, breaking a single barter transaction into two separate transactions: sale and purchase. The farmer can now sell his wheat for money and then use that money to buy shoes from any shoemaker. This separation drastically increases the volume and efficiency of trade.
• Measure of Value / Unit of Account: Money serves as a common denominator or a yardstick to express the value of all goods and services. The price of every item, from a pen to a car, is expressed in monetary units (like Rupees, Dollars, etc.). This makes it easy to compare the values of different things and facilitates economic calculation and accounting.

Secondary Functions of Money

• Store of Value: Money allows us to transfer purchasing power from the present to the future. You can earn money today and save it to spend later. While its value can be eroded by inflation, it is far more efficient and less perishable than storing wealth in the form of commodities. This function encourages saving, which is vital for investment and capital formation.
• Standard of Deferred Payment: Money facilitates credit transactions. It allows for contracts to be written where payments are promised at a future date. Since the value of money is relatively stable and universally accepted, both borrowers and lenders can be confident in the terms of the transaction. This function is the bedrock of modern lending, financial markets, and business operations.

Demand for and Supply of Money: The Economic Pulse

Like any other commodity, money has its own demand and supply dynamics, which are central to macroeconomic policy.

Demand for Money

Why do people desire to hold money, which, unlike stocks or bonds, does not earn interest? The NCERT syllabus highlights two primary motives for holding money:

• The Transaction Motive: People hold money to carry out their day-to-day transactions. We receive income at specific intervals (e.g., monthly salary), but we spend it continuously. Therefore, we need to hold a certain amount of cash to bridge this time gap between the receipt of income and its expenditure. The amount of money held for this purpose depends directly on the volume of transactions, which in turn is related to an individual's or a nation's income. Higher income generally leads to a higher demand for money for transaction purposes.
• The Speculative Motive: This is the demand for money as a financial asset. People can hold their wealth in various forms, such as money or interest-bearing assets like bonds. The speculative motive arises from the desire to avoid losses from holding bonds when interest rates are expected to change. There is an inverse relationship between the market rate of interest and the price of bonds. When the interest rate is very high, people expect it to fall in the future. A fall in the interest rate will lead to a rise in bond prices, resulting in a capital gain. So, at high-interest rates, people will hold less money and more bonds. Conversely, when the interest rate is very low, people expect it to rise. A rise in the interest rate will cause bond prices to fall, leading to a capital loss. To avoid this loss, people will hold more of their wealth as cash. Therefore, the speculative demand for money is inversely related to the rate of interest.

Supply of Money

The supply of money refers to the total stock of money in circulation among the public at a particular point in time. It is important to note that 'public' here refers to the money-using sector, i.e., individuals and business firms. It does not include the money-creating sector, namely the government and the banking system, as the cash held by them is not in active circulation.

In India, the Reserve Bank of India (RBI) publishes data on four alternative measures of money supply, denoted by M1, M2, M3, and M4.

• M1 = CU + DD
  • CU is the currency (notes and coins) held by the public.
  • DD is the net demand deposits held by commercial banks. These are deposits that can be withdrawn on demand, like those in a current account or savings account.
  • M1 is the most liquid measure of money supply.
• M2 = M1 + Savings deposits with Post Office savings banks.
• M3 = M1 + Net time deposits of commercial banks.
  • Time deposits are those with a fixed period of maturity, like Fixed Deposits (FDs). They are less liquid than demand deposits.
  • M3 is the most widely used measure of money supply and is often referred to as 'broad money'.
• M4 = M3 + Total deposits with Post Office savings organisations (excluding National Savings Certificates).

The Banking System: Architects of the Financial World

The banking system is the set of institutions that manages the supply and flow of money and credit in an economy. It is broadly divided into Commercial Banks and the Central Bank.

Commercial Banks and the Art of Money Creation

Commercial banks are the heart of the financial system. They are institutions that accept deposits from the public and use these funds to grant loans, thereby earning a profit. But their most fascinating function is the ability to create credit or 'money'. This is not about printing currency notes; rather, it's about expanding their demand deposits, which are a part of the money supply (M1).

This process is known as credit creation. It is based on two key assumptions:

1. The entire commercial banking system is treated as a single unit.
2. All receipts and payments in the economy are routed through the banks.

The amount of credit that banks can create is limited by the Legal Reserve Ratio (LRR), which is set by the central bank. LRR is the minimum fraction of deposits that commercial banks are legally required to keep as reserves and cannot lend out. It has two components: the Cash Reserve Ratio (CRR, kept with the RBI) and the Statutory Liquidity Ratio (SLR, kept by the bank with itself in the form of liquid assets).

Let's understand this with an example. Suppose the LRR is 20% (0.2).

• Round 1: A person deposits ₹1000 in Bank A. This is the primary deposit. Bank A is required to keep 20% of this (i.e., ₹200) as a reserve and can lend out the remaining ₹800.
• Round 2: The person who borrows ₹800 uses it to make a payment. The receiver of this payment deposits the ₹800 into their account in Bank B. Now, Bank B has a new deposit of ₹800. It keeps 20% of this (₹160) as a reserve and lends out the remaining ₹640.
• Round 3: This ₹640 is deposited in Bank C, which then keeps 20% (₹128) and lends out ₹512.

This process continues, with each round creating a smaller amount of new deposits. The total amount of money created in the economy is a multiple of the initial deposit. This multiple is called the Money Multiplier.

The formula for the Money Multiplier is: 1 / LRR

In our example, the Money Multiplier = 1 / 0.20 = 5.

Total Money Creation = Initial Deposit × Money Multiplier = ₹1000 × 5 = ₹5000.

Thus, an initial deposit of ₹1000 has led to the creation of total deposits worth ₹5000. This shows that the lower the LRR, the higher the money multiplier, and the greater the credit-creating capacity of commercial banks.

The Central Bank: The Reserve Bank of India (RBI)

The Central Bank is the apex institution of a country's monetary and banking system. In India, this role is performed by the Reserve Bank of India (RBI), established in 1935. It does not deal directly with the public but acts as a regulator and guide for the entire financial system. Its functions are critical for maintaining economic stability.

Key Functions of the RBI:

• Currency Authority (Bank of Issue): The RBI has the sole authority to issue currency notes in India (except for the one-rupee note and coins, which are issued by the Ministry of Finance). This ensures uniformity in the currency and gives the central bank control over the money supply.
• Banker to the Government: The RBI acts as a banker, agent, and financial advisor to the central and state governments. It maintains government accounts, manages public debt, and provides short-term credit to the government.
• Banker's Bank and Supervisor: The RBI acts as a bank for all the commercial banks in the country. Commercial banks are required to keep a certain portion of their deposits (CRR) with the RBI. The RBI also acts as a 'lender of last resort,' providing financial assistance to commercial banks facing a liquidity crisis. As a supervisor, it regulates and inspects banks to ensure they function soundly and protect depositors' interests.
• Controller of Money Supply and Credit: This is arguably the RBI's most crucial function. It uses various instruments of monetary policy to regulate the amount of credit created by commercial banks, influencing the overall money supply to achieve objectives like price stability and economic growth.

The instruments used by the RBI are categorized as quantitative and qualitative.

Quantitative Instruments (affecting the total volume of credit):

• Repo Rate: The rate at which the RBI lends money to commercial banks for their short-term needs against government securities. By increasing the Repo Rate, the RBI makes borrowing more expensive for commercial banks. They, in turn, increase their lending rates, which discourages borrowing by the public, thus reducing the money supply. A decrease in the Repo Rate has the opposite effect.
• Bank Rate: A similar tool, this is the rate at which the RBI lends to commercial banks for their long-term needs. It signals the central bank's long-term outlook on interest rates.
• Open Market Operations (OMOs): This involves the buying and selling of government securities (bonds) by the RBI in the open market. To reduce the money supply, the RBI sells securities, which sucks liquidity out of the system as banks pay the RBI. To increase the money supply, the RBI buys securities, injecting money into the banking system.
• Legal Reserve Ratios (CRR and SLR): As discussed earlier, the RBI can change these ratios. An increase in CRR or SLR reduces the funds available with commercial banks for lending, thereby contracting credit. A decrease in these ratios increases their lending capacity and expands credit.

Qualitative Instruments (directing the flow of credit to specific sectors):

• Margin Requirements: The margin is the difference between the market value of the security offered for a loan and the amount of the loan granted. By changing the margin requirements, the RBI can encourage or discourage credit for certain purposes.
• Moral Suasion: The RBI uses persuasion and informal suggestions to convince commercial banks to follow certain credit policies in the larger economic interest.
• Selective Credit Controls: These are used to control credit for specific sectors or commodities, for example, by regulating consumer credit or setting minimum down payments.
