Introduction and importance of money
Money is one of the most fundamental concepts in economics and banking. It plays a central role in all economic activities, as it enables the exchange of goods and services in an organised and efficient manner. In a modern economy, money acts as the lifeblood of trade, production, consumption, and investment.
Meaning of money
In simple terms, money is anything that is generally accepted as a medium of exchange in an economy. It is used to buy goods and services, repay debts, and store value for future use. Money has value not because of its physical form but because people have confidence that others will accept it in exchange.
Economists define money not by what it looks like, but by what it does. Therefore, anything that performs the functions of money effectively can be called money.
Evolution of money
In the early stages of economic development, people followed the barter system, where goods were exchanged directly for other goods. However, barter suffered from serious limitations such as lack of double coincidence of wants, difficulty in measuring value, indivisibility of goods, and problems in storing value.
To overcome these difficulties, money evolved in different forms over time. Initially, commodities such as cattle, grains, shells, and metals were used as money. Later, metallic money in the form of gold and silver coins became popular. With economic growth and expansion of trade, paper money emerged, followed by credit money such as cheques and drafts. In modern economies, digital and electronic money have gained importance, especially in banking and financial systems.
Functions of money
The functions of money explain why money is essential in an economy. These functions are commonly divided into primary, secondary, and contingent functions.
Primary functions of money
The most important function of money is that it acts as a medium of exchange. Money eliminates the need for direct exchange of goods and services and facilitates smooth transactions. Buyers can purchase what they need, and sellers can sell their products easily using money.
Money also acts as a measure of value or unit of account. It provides a common standard for measuring and comparing the value of different goods and services. Prices are expressed in terms of money, making economic calculation simple and uniform.
Secondary functions of money
Money serves as a store of value, meaning that wealth can be stored in monetary form and used in the future. Unlike perishable goods, money can be saved and accumulated with relative ease.
Money also acts as a standard of deferred payments. Loans, salaries, rents, and other future payments are expressed and settled in terms of money. This function is particularly important in modern credit-based economies and banking systems.
Another secondary function of money is that it acts as a means of transferring value. Money allows value to be transferred from one place to another and from one person to another without any physical movement of goods.
Contingent functions of money
Money also performs certain contingent or subsidiary functions. It helps in the distribution of national income, as wages, rent, interest, and profits are all paid in money terms. Money assists in the maximisation of satisfaction and profit, as consumers and producers try to optimise their decisions using money prices and costs.
Money forms the basis of the credit system, as banks create credit on the basis of deposits held in money form.
Characteristics of good money
For money to function effectively, it should possess certain characteristics. Good money should be generally acceptable, durable, divisible, portable, and easily recognisable. It should also be relatively scarce to maintain its value and stable in value to ensure confidence among users.
Modern paper and digital money may not possess all these characteristics in physical form, but legal backing by the government and regulation by the central bank ensure their acceptability and stability.
Types of money
Money exists in various forms in a modern economy. Commodity money has intrinsic value, such as gold or silver. Fiat money has no intrinsic value but is accepted because it is declared legal tender by the government. Credit money, such as cheques, drafts, and bank deposits, is widely used in banking transactions.
In recent years, digital and electronic money, including debit cards, credit cards, UPI, and internet banking, have become increasingly important. While these forms may not be physical money, they perform the same functions and are regulated by the banking system.
Money in the modern banking system
In a modern economy, money supply is managed by the central bank, such as the Reserve Bank of India. The central bank regulates money and credit through various monetary policy tools to ensure price stability and economic growth.
Commercial banks play a crucial role by accepting deposits and creating credit. Thus, money is not only a medium of exchange but also a tool for economic development and financial stability.
