The role of money and financial markets exam tips
Quick Revision Summary (Key Takeaway)
Money acts as a medium of exchange, store of value, unit of account, and standard of deferred payment, overcoming the inefficiencies of the barter system. Financial markets facilitate lending and borrowing by connecting savers and borrowers, underpinning commercial activity and central bank monetary policy.
Topic Overview
The role of money and financial markets explores how modern economies eliminate the double coincidence of wants inherent in barter systems. It covers the four functions of money, its key characteristics, and how financial intermediaries allocate capital between savers and borrowers.
Understanding financial institutions like commercial banks and central banks is vital for analysing macroeconomic policy. This topic connects microeconomic decisions regarding saving and borrowing with macroeconomic performance, particularly inflation control and economic growth.
Key Concepts
- →The four functions of money: medium of exchange, store of value, unit of account, and standard of deferred payment.
- →The key characteristics of money: durability, portability, divisibility, uniformity, limited supply, and acceptability.
- →The primary role of commercial banks: accepting customer deposits, providing loans, and generating profits through the net interest margin.
- →The role of the Bank of England: setting the base interest rate, regulating the financial sector, issuing legal tender, and acting as the lender of last resort.
- →The impact of interest rates on household borrowing, saving, mortgage repayments, and firm investment decisions.
Examiner Tips
- 💡Always state units clearly (e.g. £ signs or percentage symbols) when performing financial calculations to avoid dropping accuracy marks.
- 💡When explaining how interest rates affect consumers, distinguish between savers (who benefit from higher returns) and borrowers (who face higher repayment costs).
Common Mistakes
- Assuming money must have intrinsic physical value, whereas modern fiat money holds value primarily through universal legal acceptance and institutional trust.
- Believing that commercial banks only lend out money that has already been physically deposited, overlooking their ability to create bank deposits electronically through lending.
- Confusing simple interest and compound interest in numerical calculation questions.

How Students Lose Marks (Examiner Pitfalls)
Pitfall: Confusing the functions of money with the characteristics of money.
❌ Weak Answer (Loses Marks):A key function of money is that it is portable and durable so people can carry it around easily.
Example improved answer:A key function of money is serving as a medium of exchange, which allows goods and services to be traded without the need for a double coincidence of wants. In contrast, portability and durability are physical characteristics that enable an asset to perform this function effectively.
Examiner Tip: Memorise the exact four functions: medium of exchange, store of value, unit of account, and standard of deferred payment. Treat physical traits like divisibility and durability strictly as characteristics.
Pitfall: Muddling the roles of commercial banks with the distinct role of the central bank.
❌ Weak Answer (Loses Marks):Commercial banks control the UK interest rate and print banknotes to manage inflation in the economy.
Example improved answer:Commercial banks are profit-seeking retail institutions that accept deposits and provide loans to consumers and businesses. The Bank of England, as the UK central bank, is responsible for setting the official Bank Rate, maintaining price stability, issuing banknotes, and acting as the lender of last resort.
Examiner Tip: Clearly distinguish between retail/commercial banks (e.g. Barclays, HSBC) and the central bank (Bank of England) when discussing credit creation, interest rates, and monetary policy.
Step-by-Step Worked Solutions
Question: A saver deposits £4,000 into a fixed-rate savings account offering 5% simple interest per annum. Calculate the total value of the savings after 3 years.
- 1.Step 1: Calculate annual interest: £4,000 * 0.05 = £200.
- 2.Step 2: Multiply annual interest by 3 years: £200 * 3 = £600 total interest earned.
- 3.Step 3: Add total interest to the original principal deposit: £4,000 + £600 = £4,600.
Final Answer: £4,600
Question: Analyse how a rise in interest rates by the central bank affects consumer borrowing and spending in the economy. (6 marks)
- 1.Step 1: Explain the mechanism: When the central bank raises the base rate, commercial banks pass this on by increasing interest rates on overdrafts, personal loans, and credit cards.
- 2.Step 2: Link to consumer borrowing: Higher interest rates make the cost of servicing existing debt and taking out new loans more expensive, discouraging consumers from borrowing.
- 3.Step 3: Link to consumer spending and saving: Higher rates also raise the reward for saving, incentivising households to save rather than spend, which leads to a contraction in aggregate consumer spending.
Final Answer: A rise in interest rates increases the cost of borrowing and raises the return on saving, causing consumers to reduce credit-financed purchases and discretionary spending.

Key Fact: It increases their monthly mortgage repayments, reducing their discretionary disposable income.
Frequently Asked Questions
What is the difference between a function and a characteristic of money?
A function describes what money actually does in an economy, such as acting as a medium of exchange or a store of value. A characteristic describes the physical or practical qualities money must possess to perform those functions, such as portability, durability, divisibility, and scarcity.
Why is the Bank of England called the 'lender of last resort'?
The Bank of England acts as the lender of last resort by offering emergency loans to commercial banks experiencing severe liquidity shortages. This ensures solvent banks do not collapse during panics, preventing systemic bank runs and protecting wider financial stability.
How do commercial banks make a profit?
Commercial banks generate profit primarily through the net interest margin. They pay a lower rate of interest to savers who deposit money with them, and charge a higher rate of interest to borrowers taking out loans or mortgages, keeping the difference as profit.
Why does high inflation reduce money's ability to act as a store of value?
Inflation causes the general price level of goods and services to increase, which erodes the purchasing power of money over time. If prices rise rapidly, cash held in a savings account or wallet buys fewer goods in the future, rendering it ineffective as a reliable store of value.
