What this dot point is asking
The SQA wants you to define an exchange rate, explain appreciation and depreciation of the pound, and work out how a change in the exchange rate changes the prices of imports and exports for individuals and firms.
What an exchange rate is
When countries trade, they use different currencies, so one must be swapped for another. The rate at which this happens is the exchange rate.
Appreciation and depreciation
The pound's value against other currencies can rise or fall.
How exchange rates affect import and export prices
This is the part the SQA tests most: a change in the exchange rate changes the prices of traded goods. A helpful memory aid is SPICED - Strong Pound, Imports Cheap, Exports Dear.
Effects on individuals and firms
A change in the exchange rate reaches everyone:
- Individuals find foreign holidays and imported goods cheaper when the pound is strong, and dearer when it is weak.
- Importing firms pay less for foreign raw materials and goods when the pound is strong, lowering their costs; they pay more when it is weak.
- Exporting firms are more competitive abroad when the pound is weak (their goods are cheaper for foreigners) and less competitive when it is strong.
- The wider economy: a weak pound can raise UK prices because imported goods and raw materials cost more, adding to inflation; a strong pound can help keep inflation down but make exporters struggle.
Why this matters across the course
Exchange rates are the price link in global trade: they decide how a country's imports and exports are priced, so they connect directly to the global trade dot point. A weak pound raising import prices links to inflation in the UK economy area, and exchange rates affect where multinationals locate and how individuals manage spending (personal economics).
Try this
Q1. Define an exchange rate. [1 mark]
- Cue. The price of one currency in terms of another (e.g. £1 = $1.25).
Q2. The pound depreciates. State what happens to the price of UK exports for foreign buyers. [1 mark]
- Cue. They become cheaper, so foreigners buy more.
Q3. Explain one effect of a stronger pound on a UK firm that imports raw materials. [2 marks]
- Cue. Imports become cheaper, so the firm's costs fall (it pays fewer pounds for the same materials).

SQA N5 specimen4 marksDescribe what is meant by an exchange rate and explain the difference between appreciation and depreciation.Show worked answer →
An exchange rate is the price of one currency in terms of another, for example how many US dollars one pound buys (1 mark). Appreciation is a rise in the value of a currency, so the pound buys more foreign currency than before (1 mark + 1 development for the direction). Depreciation is a fall in the value of a currency, so the pound buys less foreign currency than before (1 mark for the contrast). Markers reward the definition of an exchange rate plus the correct directions of appreciation (rise) and depreciation (fall).
SQA N5 past-style6 marksExplain the effects on UK importers and exporters of a fall (depreciation) in the value of the pound.Show worked answer →
When the pound falls, UK exports become cheaper in foreign currency, so foreigners buy more UK goods and exporters tend to sell more and gain (1 mark + 1 development). At the same time imports become more expensive in pounds, because each pound buys less foreign currency, so importers and UK consumers pay more for foreign goods and raw materials (1 mark + 1 development). Dearer imported raw materials and goods can also raise UK prices, adding to inflation (1 mark + 1 development). Markers reward the export effect (cheaper, sell more), the import effect (dearer), and a link such as the inflation effect.
