Extra questions & answers
What is financial infrastructure?
It is the network of banks, payment systems, stock markets and other financial institutions that help people, businesses and the government make financial transactions and manage money.
What are the main things a bank does?
A bank holds deposits that people put in their accounts, keeping the money safe and paying interest, and lends money to borrowers as loans on which it charges interest.
How do banks make money?
They pay a lower interest rate on savings deposits and charge a higher interest rate on loans; the difference between the two is a source of income for the banks.
What is compounding, and how does the chessboard story illustrate it?
Compounding is earning interest on previous interest as well as on the original amount; the sage who asked for grains of rice doubling on each chessboard square showed how small amounts grow enormously over time.
What are the three types of bank accounts?
A savings account for regular savers that earns interest, a current account for businesses with no interest but frequent transactions, and a fixed deposit account kept for a fixed period at a higher interest rate.
What role does the Reserve Bank of India play?
The RBI is India's central bank and the 'banker to banks'; it supervises the banking system, maintains accounts of other banks, prints and distributes currency, and fixes benchmark interest rates.
How did the Pradhan Mantri Jan Dhan Yojana change banking?
Launched in 2014, it gave every Indian, especially low-income earners, access to a bank account without a minimum balance or fees, opening over 50 crore accounts, mainly for women, and enabling direct transfers.
What is UPI, and why is it called India's gift to the world?
UPI is a fast, secure digital payment system launched in 2016 that enables instant fund transfers using a QR code or phone number; several countries have adopted it, making it India's gift to the world of payments.
What is a share, and what happens on a stock exchange?
A share is a unit of ownership in a company; buying one makes a person a part-owner, and the actual buying and selling of shares takes place on a stock exchange like the Bombay Stock Exchange.
How can people stay safe from financial fraud?
By never sharing personal information like account numbers, passwords or OTPs with strangers, avoiding unknown links, not storing sensitive banking details on devices, and reporting fraud via the 1930 helpline or the cybercrime portal.
The Big Questions
1. What is financial infrastructure, and what does it comprise?
Financial infrastructure is the network of institutions, systems and rules that helps money to move and be managed in an economy. It comprises banks and other financial institutions, payment systems like cheques, debit cards, internet banking and UPI, the stock market and stock exchanges, and the regulating body the Reserve Bank of India which sets rules for all of them.
2. What are the main functions performed by banks and how do they impact people’s lives?
Banks mainly hold deposits safely, pay interest on savings, and give loans or credit for needs like education, houses, farming and business. They also help people withdraw money and transfer money through cheques, ATMs, debit cards and digital systems. This impacts lives by encouraging saving, making transactions safe and easy, and giving access to money when needed, as seen with Navdeep who could save safely and Rima who could borrow for her business.
3. How does financial infrastructure contribute to a nation’s progress?
It keeps the flow of money smooth between households, businesses and the government. It promotes savings through interest and compounding, provides credit for investment in farms, industry and physical infrastructure like roads, and allows quick digital payments and raising of funds through shares. The chapter notes that wider access, for example through Jan Dhan Yojana, brings more people into the economy and helps the nation grow.
LET'S EXPLORE
This picture is from a bank. What do you think the people are doing? Ask your family members if they have visited a bank and learn more about the activities there.
In the picture people are doing usual bank work. Some customers are sitting at counters talking to bank staff, submitting slips or asking for information, while staff are helping them. Others are waiting for their turn. A person is using a phone, perhaps checking a transaction. If you ask family members, they will say they go to a bank to open accounts, deposit cash or cheques, withdraw cash, update passbooks, apply for loans, or get a debit card and cheque book.
THINK ABOUT IT
Why does Navdeep think that saving at the bank is better than keeping cash at home?
Saving at home in a cupboard is unsafe because cash can be stolen, lost or damaged, and it does not grow. In a bank the money is kept safely, there is a record of deposits and withdrawals in a passbook, the money can be withdrawn when needed, and the bank pays interest so the amount increases over time through compounding.
Can Navdeep and Rima lend to each other directly without the bank? What could happen in that case? Discuss.
In theory Navdeep could lend his surplus
THINK ABOUT IT
How does one track so many transactions of deposits and withdrawals? The bank provides a diary-like document called a passbook that keeps a record of all the receipts and payment transactions. This can be updated regularly at the bank.
Every deposit and withdrawal is recorded by the bank. The passbook is a small diary given to the account holder that lists date, particulars, cheque number, debit which is money taken out, credit which is money received, and the remaining balance. Today the same record is also available as a printed statement at the bank, and as an online or mobile banking transaction history and SMS alerts, so the holder can check all movements at any time.
Look at the passbook in Fig. 8.7. Observe all the particulars under the expenses (debit) and income (credit). Why is keeping records of financial transactions important? Discuss in the class.
The passbook in Fig. 8.7 shows salary credit, rent payment and shopping debits, cash deposit credit, SMS charges debit and interest credit, with the balance after each entry. Keeping such records is important because it helps a person know how much was earned, spent and saved, plan a budget, prove income or payment if there is a dispute, calculate interest earned or due, and detect any fraud or error quickly. For banks and for tax purposes it is also a legal proof of transactions.
THINK ABOUT IT
Why do companies issue shares, and why do people buy them? Are there any benefits of owning shares?
Companies issue shares to raise money from many people without taking a loan. This capital is used to expand business, buy machines, develop new products or build infrastructure. People buy shares to invest their savings and become part-owners of the company. Benefits of owning shares include getting a share of profit as dividend if the company does well, and gaining when the share price rises so the investment can be sold at a higher price. However prices can also fall, so there is risk of loss.
Questions and activities
1. What is financial infrastructure? How does it complement physical infrastructure?
Financial infrastructure is the network of banks, post offices and other financial institutions, payment systems such as cash, cheques, debit cards, POS machines, internet banking and UPI, the stock market, and the regulator the Reserve Bank of India. Physical infrastructure like roads, railways and telecom needs large funding for building and maintenance. Financial infrastructure complements it by collecting savings as deposits, giving loans and credit to businesses and the government, enabling quick payments, and helping raise funds through shares, so the money needed for physical infrastructure can flow smoothly.
2. How does having a bank account help people? Should everyone be required to have a bank account?
A bank account keeps money safe, allows easy deposit and withdrawal through slips, ATMs and debit cards, provides a passbook and digital record of transactions, pays interest on savings so money grows, and makes it possible to receive wages, scholarships and government transfers directly and to get loans when needed. Access has widened through Jan Dhan Yojana with no minimum balance. Whether everyone should be required is a matter for discussion: while universal access helps include everyone and reduce cash and middlemen, some people may prefer not to use banks or may live far away, so the aim is to make accounts accessible and voluntary with awareness, rather than compulsory.
3. What could be the possible advantages and disadvantages of compound interest for savers and borrowers?
For savers, compounding is an advantage because interest is earned not only on the original amount but also on interest already earned, so money grows faster over time. For example
4. How does financial infrastructure enable the flow of money between households and businesses? Can you think of how the government can facilitate this flow?
Households deposit savings in banks. Banks use those deposits to give loans to businesses for buying raw material, machines, transport and expansion. When businesses earn profit they pay wages to households, who again spend or save, so money circulates. Financial infrastructure enables this through accounts, loans, cheques, cards and UPI. The government can facilitate it by opening more bank accounts like Jan Dhan, supporting post office savings and banks like NABARD for farmers, making digital payments safe and cheap, and ensuring RBI rules keep banks stable, plus direct benefit transfers that send subsidies and scholarships straight to bank accounts without middlemen.
5. What could be the reason for the higher interest rate earned on fixed deposits as compared to a savings account?
A savings account allows money to be deposited and withdrawn frequently, so the bank cannot be sure how long the money will stay and must keep it readily available. A fixed deposit is locked for a fixed period such as 3 or 5 years. Because the bank can safely lend that money for a longer time and plan its use, it rewards the saver with a higher rate of interest than a savings account.
6. Sahil received ₹10,000 as a prize in a poster-making competition. His father promises to pay him 12 per cent interest per year if he does not spend the amount. After 3 years, how much money would Sahil have?
His father pays compound interest at
7. How does the stock market help mobilise the savings of individuals? In what ways do companies benefit by issuing shares to people?
The stock market, for example the Bombay Stock Exchange, is a marketplace where shares are bought and sold digitally. It mobilises savings by letting individuals invest small amounts to become part-owners of companies and benefit if the company does well. Companies benefit because issuing shares brings large funds from many investors at once to expand operations without borrowing and repaying interest, and it increases the company's reputation and ability to raise more capital.
8. How can we balance the convenience of digital payments with the risk of cyber fraud?
We can enjoy quick payments through UPI, cards and internet banking while staying safe by never sharing PIN, password or OTP, not clicking unknown links, not storing sensitive details on the phone, using strong PINs and updating apps, checking SMS and passbook entries regularly, and reporting suspected fraud immediately on helpline
9. Ask your family members or neighbours about— how they save money?
In a small survey at home, most family members said they save by depositing a part of income in a bank savings account or a post office scheme such as NSC or Sukanya Samriddhi, some keep a fixed deposit for long-term goals, while elders also mentioned keeping a small amount of cash at home for emergencies and using digital methods to track savings.
9. Ask your family members or neighbours about— whether they use UPI, ATM or cheques, the kinds of transactions they perform through UPI; do they find UPI better than using cash or not, and why.
Most persons use UPI for daily payments like buying vegetables, groceries, paying auto fares and mobile recharges, and use ATM debit cards to withdraw cash and cheques for larger payments such as rent or school fees. They find UPI better than cash because it is instant, works with a QR code or phone number, avoids the need to carry cash or visit the bank, provides an automatic transaction record on the phone, and works even during holidays.
9. Ask your family members or neighbours about— if they or their acquaintance have experienced digital fraud, for instance, through a fake call or message asking for bank details. What did they do when they realised it was a scam, and what did they learn from that experience?
One neighbour received a fake call claiming to be from the bank and asking for OTP to block a card. He realised it was a scam because banks never ask for OTP on phone, disconnected, blocked the number, and reported it on
9. Summarise your findings in a table or short report. Share one surprising insight with your class.
A short report can have columns for Name, Saving method, Payment method used, UPI uses, View on UPI vs cash, Fraud experience. A surprising insight to share could be that women in the household now use Jan Dhan accounts actively and that many small vegetable vendors prefer UPI over cash because it saves change and gives a record, showing how far digital inclusion has reached.
10. Create a Financial Safety Poster. Design a poster with dos and don’ts of digital banking safety (for example, not sharing OTPs, reporting frauds).
Poster title: Stay Safe with Digital Banking. Do's: keep PIN and OTP secret, use strong passwords, check transaction alerts, lock phone with screen lock, update payment apps. Don'ts: don't share OTP or password on phone, don't click unknown links, don't write PIN on card, don't store passwords in notes on phone.
10. Create a Financial Safety Poster. Include emergency numbers or websites like https://cybercrime.gov.in or 1930 helpline.
Poster should clearly display at the bottom: If you are a victim of fraud, call immediately
10. Create a Financial Safety Poster. Hang the posters in school corridors or the library.
The finished poster can be made on A3 paper with bold headings, icons for a lock, phone and warning sign, and colours for do's in green and don'ts in red, then displayed on the school notice board, corridor or library wall and explained to juniors during assembly.
11. Cheques are often used to pay utility bills. Ask your parents to allow you to fill out the cheques for a few monthly payments.
With parents' permission, take a cancelled cheque leaf and practise: write the date, payee name such as Electricity Board, amount in words and figures, and sign. Never sign a blank cheque. Check that the MICR code, cheque number and your account number are printed. Then submit the cheque to the payee or its drop box and keep the record.
12. Suppose you have to withdraw ₹10,000 from your bank account, how would you fill out the cash withdrawal slip at your bank? Let us try below!
On the withdrawal slip fill: Date of withdrawal, savings account number, amount in figures
