Class 7 Social Science Part 2 Chapter 8: Banks and the Magic of Finance Notes
This chapter in five lines
Banks and the Magic of Finance is about financial infrastructure: the banks, payment systems, stock markets and other institutions that move money between people, businesses and the government. Banks keep deposits safe, pay interest that grows by compounding and lend to borrowers, under the rules of the Reserve Bank of India. Payments have moved from cash and cheques to cards and UPI, shares let people own parts of companies, and everyone must guard against fraud.
What is this chapter about?
The last chapter showed the roads, railways and networks that carry goods and people. But who pays the workers, how do shoppers pay shopkeepers, and where does the money for a new highway come from? The answer is financial infrastructure: banks, payment systems, stock markets and other institutions through which people, businesses and the government move and manage money.
Banks: deposits and loans
Navdeep saves ₹3000 a month, but cash in a cupboard is not safe, so he deposits it in a bank. Rima, who makes bamboo products, needs more money for her business than friends can lend, so she borrows from the bank. The bank keeps Navdeep’s money safe, pays him interest and lends it to Rima, who repays it with interest. Banks offer savings accounts for regular savers, current accounts for businesses and fixed deposits for money set aside for a few years. Read more in how banks work.
The magic of compounding
Interest is the reward for saving and the price of borrowing. If ₹1000 earns 6% a year, it becomes ₹1060 after one year. In the second year interest is paid on ₹1060, so the total becomes ₹1123.60. Earning interest on interest is compounding; after 12 years the ₹1000 grows to about ₹2012.20. A story from Ambalappuzha in Kerala makes the same point: a sage asked a king for rice that doubled on every square of a chessboard, and by the 32nd square the grains passed 210 crore.
The RBI and banking for all
Banks pay depositors a lower rate than they charge borrowers, and the gap is their income. The Reserve Bank of India, set up in 1935 and the central bank since 1949, supervises them, keeps their accounts, issues currency and fixes the benchmark interest rate. Post offices, NABARD and IFCI also provide financial services. The Jan Dhan Yojana of 2014 opened over 50 crore bank accounts, so wages and scholarships now reach people directly.
Ways to pay
Money can be taken out with a withdrawal slip or from an ATM with a debit card. A cheque pays someone from your account but takes time. Debit cards, net banking and above all UPI, launched in 2016, make payments instant: scan a QR code, enter the amount and the UPI PIN, and the money moves. Nepal, the UAE, France, Sri Lanka, Bhutan and Mauritius have adopted UPI. See digital payments and UPI.
Shares and staying safe
A share is a piece of ownership in a company, bought and sold at a stock exchange such as the Bombay Stock Exchange, set up in 1875. Share prices rise and fall, so shares can bring gains or losses. Read shares and the stock market. Finally, digital money brings new risks: fraudsters use fake calls and messages to steal OTPs and bank details. Report any fraud on the 1930 helpline. Answers to every question are in the NCERT solutions for Part 2 Chapter 8.
