1. Chapter at a Glance
Imagine a world without money. A shoemaker who wants wheat would have to find a farmer who has wheat and wants shoes at the same time. Trade would be slow and frustrating. Money solves this problem. Today money exists as coins, currency notes, bank deposits, cheques and digital payments through phones. Closely linked to money is credit — loans that let a farmer buy seeds before harvest, a shopkeeper stock goods before festival sales, or a family build a house. Credit can help people prosper, but it can also trap them in debt. This chapter explains how money works, how banks create credit, why the terms of credit matter, and how the poor can get cheaper loans through formal sources and self-help groups.
- Money as a medium of exchange and the problem of double coincidence of wants.
- Modern forms of money: currency and demand deposits; role of the RBI.
- How banks use deposits to give loans.
- Two sides of credit — productive credit and debt traps.
- Terms of credit: interest, collateral, documentation, repayment.
- Formal and informal sources of credit and why formal credit must expand.
- Self-help groups for the poor.
2. Money as a Medium of Exchange
In a barter system, goods are exchanged directly for goods. Trade happens only when what one person wants to sell is exactly what the other wants to buy, and vice versa — the double coincidence of wants. This is rare and makes barter inefficient.
Money acts as an intermediate in exchange — a medium of exchange. The shoemaker sells shoes for money and uses money to buy wheat from any farmer. The double coincidence is no longer needed. Money also serves as a common measure of value and a way to store value for the future.
3. Modern Forms of Money
Over history, many things have served as money — grains, cattle, shells, and later coins of gold, silver and copper. Today we use:
- Currency — paper notes and coins. In India, currency is issued by the Reserve Bank of India (RBI) on behalf of the central government (one-rupee notes are issued by the Government of India). Currency is accepted because the law authorises it as a medium of exchange; no individual can legally refuse rupees in settling transactions in India.
- Deposits with banks — people deposit extra cash in bank accounts and earn interest. Because money in a savings or current account can be withdrawn on demand, these are called demand deposits. Payments can be made from them by cheque, debit card, net banking or UPI on a mobile phone, without handling cash.
A cheque is a paper instructing the bank to pay a specific amount from the account holder's account to the person named on it. If Salim pays a supplier ₹20,000 by cheque, the supplier deposits it in his bank; the amount is transferred from Salim's account to the supplier's. Demand deposits thus share the essential features of money.
4. Loan Activities of Banks
Banks keep only a small part of their deposits as cash to meet the daily withdrawals of depositors, because on any given day only some depositors withdraw money. They use the major part of deposits to extend loans to farmers, businesses, families and others.
- Banks pay interest on deposits and charge a higher interest on loans.
- The difference between the two is the main source of income for banks.
- Thus banks act as intermediaries between those who have surplus funds (depositors) and those who need funds (borrowers).
A bank pays 4% a year on deposits and lends at 10%. If it lends ₹1 crore of deposits for a year, how much does it earn before costs?
Solution: Interest received = ₹10 lakh; interest paid = ₹4 lakh; gross margin = ₹6 lakh, out of which it pays salaries and other expenses.
5. Two Different Credit Situations
Credit (loan) is an agreement in which the lender supplies money, goods or services to the borrower in return for the promise of future payment.
| Situation | Story (illustrative) | Outcome |
|---|---|---|
| Credit helps | A shoe manufacturer takes credit from leather suppliers and advance payments from traders before the festival season, completes the order on time and earns profit. | Credit raises earnings — the borrower is better off. |
| Credit traps | A small farmer borrows from a moneylender at high interest to grow a crop. The crop fails due to pests; the loan cannot be repaid, so the farmer borrows again, and the debt grows. Finally the farmer sells part of the land to repay. | A debt trap — the borrower is worse off. |
Whether credit is useful depends on the risks involved and on whether there is support in case of loss, such as crop insurance.
6. Terms of Credit
Every loan agreement specifies: the interest rate; the collateral (security) required; the documentation needed; and the mode and period of repayment.
Collateral is an asset the borrower owns (land, building, vehicle, livestock, bank deposits) and pledges to the lender as a guarantee until the loan is repaid. If the borrower fails to repay, the lender may sell the collateral to recover the money.
Terms vary greatly by lender and borrower. Banks often require collateral and proper documents, which many poor households lack. That is one major reason the poor fall back on informal lenders.
7. Formal and Informal Sources of Credit
| Basis | Formal sources | Informal sources |
|---|---|---|
| Examples | Banks, cooperatives | Moneylenders, traders, employers, relatives and friends |
| Supervision | Supervised by the RBI | No organisation supervises them |
| Interest | Lower, regulated | Often much higher |
| Collateral and documents | Usually required | Flexible, based on personal knowledge |
| Recovery | Legal means | May use unfair means; may tie borrower to the lender |
The RBI monitors whether banks maintain cash balances, and also checks that banks lend not just to profitable businesses but also to small cultivators, small-scale industries and small borrowers.
Why formal credit must expand: high-interest informal loans mean a large part of earnings goes in repaying loans, leaving less for the borrower. Cheap and affordable credit is crucial for development — it allows people to grow crops, run businesses and set up small industries. Formal credit is also more likely to reach the poor fairly if access is widened. In India, a large share of the credit needs of poorer rural households is still met by informal sources, while richer households rely more on formal sources — so the goal is to expand formal credit, especially to the poor.
8. Self-Help Groups for the Poor
A Self-Help Group (SHG) typically has 15–20 members, often women, usually from one neighbourhood. Members pool small savings regularly (for example, ₹50–₹100 a month). The group lends to members from this fund at a reasonable interest rate. After a year or two of regular saving, the group becomes eligible for a bank loan in the name of the group, without collateral. Members use loans to release mortgaged land, meet working-capital needs, buy assets such as sewing machines or cattle, or for housing.
- Most important decisions — loan size, purpose, interest, repayment — are taken by the group members.
- The group is responsible for repayment; non-repayment by one member is followed up by others, which keeps repayment high.
- SHGs help women become financially self-reliant, gain confidence and discuss social issues such as health, nutrition and domestic violence.
The idea of collateral-free group lending was made famous by the Grameen Bank of Bangladesh, founded by Professor Muhammad Yunus, who along with the bank received the Nobel Peace Prize in 2006.
9. Case Studies and Solved Problems
Megha needs ₹5,000 urgently for her child's treatment. The bank asks for collateral and documents; a moneylender gives the loan at once but at a very high interest. Why might she take it, and what is the risk?
Answer: She lacks collateral and cannot wait. The risk is that high interest makes repayment hard, leading to more borrowing — a debt trap. An SHG loan would be a better option if available.
₹10,000 for one year: Option A (bank) at 12% a year; Option B (moneylender) at 3% per month (simple interest). Compare.
Answer: A: interest ₹1,200. B: 3% × 12 = 36% a year → ₹3,600. The moneylender's loan costs three times as much.

12. Mind Map
- Medium of exchange
- Currency, deposits
- Deposits → loans
- RBI supervision
- Terms of credit
- Debt trap
- Formal, informal

13. Tips and Tricks
- For "why demand deposits are money", mention: withdrawable on demand + usable for payments (cheques, UPI).
- For formal vs informal, always include supervision by RBI, interest rate and collateral.
- Convert monthly interest to yearly (× 12) when comparing loans.
- Saying banks keep all deposits as cash — they keep only a small part.
- Confusing collateral (security) with interest (price of a loan).
- Writing that SHGs are run by banks — they are run by members themselves.

15. Exam-pattern Questions with Detailed Answers
Who issues currency notes on behalf of the central government in India?
- State Bank of India
- Reserve Bank of India
- Finance Commission
- NABARD
Show answer
The RBI is India's central bank and issues currency notes on behalf of the government.
Answer: (B)
What is collateral?
Show answer
An asset owned by the borrower (land, building, vehicle, livestock, deposits) pledged to the lender as a guarantee until the loan is repaid.
Answer: Asset used as security for a loan
Name two formal and two informal sources of credit.
Show answer
Formal: banks, cooperative societies. Informal: moneylenders, traders (also employers, relatives, friends).
Answer: Banks, cooperatives; moneylenders, traders
How does money solve the problem of double coincidence of wants?
Show answer
Money is accepted by everyone as a medium of exchange. A seller exchanges goods for money and uses money to buy from anyone else, so the exact two-way match of wants is no longer required.
Answer: By acting as a universally accepted intermediate
Why are demand deposits considered money?
Show answer
They can be withdrawn on demand and used directly to make payments through cheques, cards or UPI, without cash. So they perform the main function of money — medium of exchange.
Answer: They are withdrawable on demand and used for payments
Explain how banks act as intermediaries.
Show answer
Banks accept deposits from people with surplus funds and pay them interest. They keep a small part as cash and lend the rest to people who need funds, charging higher interest. They thus connect savers and borrowers and earn from the interest difference.
Answer: Link savers and borrowers; earn the interest margin
Why do poor households depend more on informal sources of credit?
Show answer
Banks are absent in many villages, require collateral and documents that the poor lack, and take time. Moneylenders know borrowers personally, lend quickly without collateral and are willing to give small loans — though at high interest.
Answer: Lack of collateral, documents and access to banks
Compare the cost of ₹20,000 borrowed for a year at 1% per month and at 2.5% per month (simple interest).
Show answer
1% × 12 = 12% → ₹2,400. 2.5% × 12 = 30% → ₹6,000. The second costs ₹3,600 more.
Answer: ₹2,400 vs ₹6,000
"Credit has its own unique role for development." Discuss both sides.
Show answer
Positive: credit lets producers buy inputs, expand business and meet working-capital needs, raising incomes (e.g. the shoe manufacturer). Negative: high-interest credit with risky activities (rain-fed farming without insurance) can lead to a debt trap and loss of assets. Therefore cheap, affordable formal credit with risk support is essential for development.
Answer: Credit raises incomes when cheap and well-used; can trap when costly and risky
Explain the working and advantages of self-help groups.
Show answer
15–20 members save regularly, lend internally at fair interest, and after a year or two receive collateral-free bank loans as a group. Members decide terms; the group ensures repayment. Advantages: access to cheap credit without collateral, freedom from moneylenders, women's empowerment, a platform to discuss social issues and start income-generating activities.
Answer: Group savings + collateral-free bank loans; empowerment and cheaper credit
Why should the RBI supervise banks' lending?
Show answer
To ensure banks keep adequate cash to protect depositors, follow sound lending practices, and lend not only to large profitable firms but also to small farmers, small industries and weaker sections. Supervision maintains trust in the banking system and supports inclusive development.
Answer: Safety of deposits and fair, inclusive lending
Suggest measures to make formal credit reach the rural poor.
Show answer
Expand bank branches, business correspondents and digital banking in villages; promote SHGs and cooperatives; simplify documents; give collateral-free small loans; link credit with crop insurance; and enforce priority-sector lending to small borrowers.
Answer: Wider access, SHGs/cooperatives, simpler terms, insurance-linked credit
