Globalisation and international trade explains why countries buy and sell across borders, how governments restrict trade and how money changes hands. This page shows how the four skills connect and the order to study them.
The area sits inside SPM Economics, and it is easier once you have met demand and supply.
What are the four skills in this area?
Each lesson builds on the one before it.
- Explaining reasons for trade: why countries exchange goods.
- Comparing trade restrictions by mechanism: what each restriction does to price and quantity.
- Interpreting exchange rate changes: what a rise or fall does to import and export prices.
- Reading balance of payments information within scope: how trade and other flows are recorded.
For extra drills, the trade and exchange rate reasoning sub-area gives smaller steps. Then test the whole area with the practice set.
How does one island example link them?
Take the fictional island of Pulau Bayu, which grows coconuts but has no steel. It exports coconuts and imports steel, which is the reason for trade.
Suppose its government places a tax on imported steel. The price of steel rises for the island’s builders, which is a trade restriction at work.
Now suppose the island’s currency becomes cheaper against the steel seller’s currency. The steel costs more in local money even with no tax, because the exchange rate moved.
Each of these can be recorded in the island’s payments with the outside world. The four skills in this area are four views of the same flows.
Who should start where?
A student new to trade starts with reasons for trade, even if the ideas feel familiar. A student who is confident with the reasons but loses marks on numbers goes straight to the exchange rate lesson.
If the direction of a rate keeps flipping, use converting a quoted exchange rate in the correct direction.
When does one-to-one help?
Free lessons show the method. A teacher watching you convert a rate can see the moment you multiply instead of divide, which a page cannot do. See online one-to-one Economics tuition if you want that.
