What this lesson teaches
I can explain why governments use policy to raise living standards.
Syllabus 8843, 3.2.3(a). Macroeconomic Policies: Macroeconomic policy decisions undertaken by governments to achieve macroeconomic objectives in relation to living standards
I can explain fiscal, monetary and supply-side policy and judge how well each works.
Syllabus 8843, 3.2.3(b). Macroeconomic Policies: Policy measures and their effectiveness in achieving macroeconomic objectives:; Fiscal policy - How discretionary fiscal policy can influence the level of economic activities and living standards through government spending and taxation; Supply-side policies - How supply-side policies can improve quantity, quality and mobility of factors of production to increase the productive capacity of an economy and hence affect living standards; Monetary policy - How monetary policy can influence the level of economic activities and living standards through the management of exchange rates (case of Singapore) and interest rates
Make a guess
A central bank's policy rate is 3% while inflation is 6%. Is borrowing expensive in real terms?
- Yes. A 3% interest rate is high.
- No. The real interest rate is about -3%.
- Yes, the real rate is 9%, adding both.
Show the answer
No. The real interest rate is about -3%.
The real rate is the nominal rate minus inflation. Borrowers repay money that has lost more value than the interest they pay.
A whole H1 case study: 40 marks, about 90 minutes in the exam. Answer every part, then compare with the suggested answers.
This is a complete case study in exam format. It is about how central banks fought the inflation of 2022 and how their decisions spread to other economies. It has eight parts worth 40 marks, like each H1 case study. In the exam you have 3 hours for two case studies, so allow about 90 minutes for this one, including reading time.
The events in the extracts are real. Country A and every number in Figure 1 and the tables are illustrative: invented for practice, not official data.
Allow about 80 to 90 minutes. Read the data and all three extracts first. Write each answer before you open its suggested answer, and use the level descriptors below to mark the 8- and 10-mark parts.
The extracts
Extract 1: The Fed's fight against inflation
In June 2022, consumer prices in the United States were 9.1% higher than a year earlier, the fastest rise in about 40 years. The US central bank, the Federal Reserve (the Fed), then raised its policy interest rate. It went from near zero in March 2022 to a range of 5.25% to 5.5% by July 2023. Higher rates made home loans, car loans and business borrowing dearer. Inflation slowed over the next two years, while unemployment stayed close to 4%, lower than many economists had expected. The Fed began to cut its rate in September 2024. Written for these notes from public information.
Extract 2: Singapore takes a different road
Singapore does not set an interest rate to control inflation. The Monetary Authority of Singapore (MAS) manages the Singapore dollar against a basket of currencies. Between October 2021 and October 2022, MAS tightened monetary policy five times, letting the Singapore dollar strengthen faster. A stronger currency makes imported food, fuel and materials cheaper in Singapore dollars. Interest rates in Singapore still rose in 2022 and 2023, because they largely follow world rates. The government also gave cash payments and vouchers, with more help for lower-income households, to ease the rise in living costs. Written for these notes from public information.
Extract 3: When US rates rise, others feel it
When US interest rates rise, investors can earn more by holding US dollar assets. Money flows out of other economies and into the United States, and the US dollar strengthens. In 2022, the currencies of many economies, including Japan and the United Kingdom, fell sharply against the US dollar. A weaker currency raises the price of imports and adds to inflation at home. Economies that have borrowed in US dollars find their debts harder to repay. Some central banks raised their own interest rates to protect their currencies, even though their economies were slowing.

How the 8- and 10-mark parts are marked
Data parts (1 to 3 marks)
Point-marked. A 'compare' part gives 1 mark for a similarity or difference with figures and 1 for a second point. A 'calculate and explain' part gives marks for the working, the answer and what it shows.
8 marks: L2 (4 to 6)
Two-sided analysis. Both sides are explained with clear chains and tied to evidence from the extracts. A top L2 answer develops both sides fully.
8 marks: L1 (1 to 3)
One-sided, or points listed without explanation, or little use of the case.
8 marks: E (1 to 2)
E2: a reasoned judgement in the context of the case that says what the answer depends on. E1: a judgement that is stated but not explained.
10 marks: L2 (4 to 7)
Both policies are analysed with developed chains, their limits and case evidence. If only one of the two policies is developed, the answer is usually capped at about 5.
10 marks: L1 (1 to 3)
Mostly descriptive, one-sided, or not tied to the case.
10 marks: E (1 to 3)
E3: a well-reasoned judgement on which policy is more effective and why, with a conclusion. It uses criteria such as the cause of inflation, time lags and side effects. E2: a reasoned judgement with less support. E1: an unsupported judgement.
| Year | Inflation rate (%) | Policy interest rate (%) |
|---|---|---|
| 2021 | 4.0 | 0.5 |
| 2022 | 7.0 | 2.5 |
| 2023 | 4.0 | 4.5 |
| 2024 | 3.0 | 5.0 |
| 2025 | 2.5 | 4.5 |
| Feature | Country A | Singapore |
|---|---|---|
| Total trade (% of GDP) | 30 | over 300 |
| Share of household loans with interest rates that change often (%) | 70 | most home loans |
| Main tool of monetary policy | Policy interest rate | Exchange rate |
Worked example: Compare two series for 2 marks
Suppose a chart shows a country's exports and imports from 2020 to 2024. Exports rose from 50 to 80; imports rose from 60 to 70. The question asks you to compare them.
- Similarity (1 mark): both exports and imports rose over the period.
- Difference (1 mark): exports rose faster, by 30 against 10, so exports overtook imports.
- Quote figures and years for each point.
- A comparison links the two series in each sentence; it does not describe them one after the other.
Watch out for this
Inflation fell from 7% to 4%, so prices in Country A fell.
A lower inflation rate means prices rose more slowly, not that they fell. Prices fall only when inflation is negative, which is deflation.
Check your understanding
By 2024 Country A has lifted its policy rate to 5%, and prices are rising 3% a year. How tight is policy now?
- Extremely tight: the real rate is about 8%, adding both rates.
- Loose: the real rate is about -2%, so borrowing is still cheap.
- Tight: at about +2%, the real rate now makes borrowing costly.
Show the answer
Tight: at about +2%, the real rate now makes borrowing costly.
Right. 5 - 3 = +2%. Moving from about -4.5% to +2% is what turns policy from loose to tight.
