Economics: Money and Credit

The One Thing

Money makes exchange more efficient than barter, while credit connects savings with consumption and productive activity. Credit can promote development when its terms are fair and repayment is manageable, but financial inclusion and regulation are necessary to protect borrowers from excessive costs and debt traps.

Who and What

• Barter system: A system in which goods and services are exchanged directly for other goods and services. It is limited by the need for a double coincidence of wants.
• Double coincidence of wants: The situation in which both participants in a barter exchange must want what the other possesses and be willing to exchange it.
• Money: Anything widely accepted as a means of payment for goods and services and for settling debts. It is trusted because it can be used to purchase goods and services from others.
• Medium of exchange: The function of money that permits buying and selling without the direct exchange of goods.
• Currency: Notes and coins used as money and accepted as legal tender for payments.
• Legal tender: Money that must be accepted by law for the payment of debts.
• Demand deposits: Money kept in bank accounts that can be withdrawn whenever the account holder demands it. They are considered money because they can be used for payments through cheques, cards, or digital methods.
• Cheque: A written instruction to a bank to pay a specified amount from one person’s account to another person or organisation.
• Credit: An arrangement in which a borrower receives money, goods, or services immediately and promises to repay later, usually with interest.
• Interest: The additional amount paid by a borrower to a lender for using borrowed money.
• Collateral: An asset, such as land, a house, or a vehicle, pledged as security for a loan.
• Terms of credit: The conditions of a loan, including the interest rate, collateral, required documents, repayment period, and method of repayment.
• Formal sources of credit: Regulated lenders, such as commercial banks and cooperative societies, that follow rules set by financial authorities.
• Informal sources of credit: Unregulated lenders, including moneylenders, traders, employers, relatives, and friends.
• Debt trap: A situation in which a borrower cannot repay a loan and must take further loans, causing the debt to increase.
• Reserve Bank of India: India’s central bank. It supervises banks, regulates the formal credit system, and manages the currency and monetary system.
• Self-help group: A small voluntary group, often formed by rural women, that saves regularly, provides small loans to members, and may obtain bank loans.
• Financial inclusion: Ensuring that all people, particularly low-income and disadvantaged groups, can access affordable and useful financial services.

Causes and Consequences

• Barter creates exchange difficulties. Direct exchange requires a double coincidence of wants: each person must want what the other person has. Money solves this problem by functioning as a medium of exchange, making transactions faster and more efficient.

• Trust gives money its practical value. Money is accepted because people expect that it can later be exchanged for goods and services. Modern money includes currency and demand deposits in banks.

• Currency provides legally recognised payment. Currency notes in India are issued by the Reserve Bank of India, except the one-rupee note and coins, which are issued by the Government of India. Currency is legal tender and must be accepted by law for the payment of debts.

• Demand deposits extend the meaning of money. Bank deposits can be withdrawn on demand and used for payments through cheques, cards, or digital methods. A cheque transfers money from one person’s bank account to another person or organisation without requiring the physical movement of currency.

• Banks connect savers and borrowers. Banks accept deposits from people and use a major portion of these deposits to provide loans. They therefore support both consumption and productive activities.

• Banks earn income through lending. Their income includes the difference between the interest charged on loans and the interest paid on deposits, together with other service charges.

• Credit creates a future repayment obligation. A borrower generally repays the principal amount plus interest and other charges. A loan may be secured by collateral, although some loans are provided without collateral depending on the borrower’s income, records, and the lending conditions.

• The cost of credit depends on several terms. It is determined mainly by the principal amount, interest rate, additional fees, and repayment period. When the rate is expressed as a percentage per year:

$$\text{Interest}=\frac{\text{Principal}\times \text{Rate}\times \text{Time}}{100}$$

The total amount to be repaid is:

$$\text{Total amount to be repaid}=\text{Principal}+\text{Interest}+\text{Other charges}$$

• The usefulness of credit depends on its purpose and terms. Credit can increase income when used to buy seeds, tools, livestock, or equipment for a productive activity. It can become harmful when income is uncertain, the interest rate is high, or the borrower must sell assets to repay the loan.

• Formal credit offers greater regulation and protection. Commercial banks and cooperative societies are supervised by the Reserve Bank of India or other authorised regulatory bodies and must follow lending rules. Formal loans generally provide greater transparency, legal protection, and more reasonable conditions.

• Informal credit may be easier to obtain but less fair. Moneylenders, traders, employers, relatives, and friends may not require extensive documents or collateral. However, informal lenders are usually not supervised by a financial regulator, so their interest rates and conditions may be unfair or difficult to verify.

• Limited access to formal credit sustains informal borrowing. Formal lenders may require documents, collateral, regular income, or complicated procedures. Consequently, easier access to informal credit does not necessarily mean that the credit is fair or affordable.

• Unmanageable loans can create debt traps. If a borrower cannot repay a loan, further borrowing may be required, causing the debt to increase. High interest, uncertain income, and the loss of productive or household assets can intensify this problem.

• Self-help groups improve access to finance. They encourage regular saving, provide small loans to members, reduce dependence on moneylenders, and may help members obtain bank loans. They therefore support participation in the formal financial system, particularly among rural women.

• Financial inclusion reduces financial inequality. It includes access to bank accounts, affordable credit, savings facilities, insurance, pensions, secure payment systems, and financial literacy. These services help disadvantaged groups save securely, borrow affordably, and manage financial risks.

• Responsible borrowing limits the risks of credit. Borrowers should compare interest rates, understand all loan conditions, assess their ability to repay, and keep proper records. Fair formal financial services, together with financial inclusion, can support economic progress while protecting borrowers.
