International Trade and Exchange Rates for ACCA BT

Updated 11 October 2026 · Fact-checked

International trade and exchange rates cover how countries buy and sell goods, services and capital across borders. The balance of payments records these flows. Exchange rates set the price of one currency in another. To solve questions, identify who gains or loses: exporters, importers or borrowers. Then link to trade barriers or blocs.

Understand International Trade and Exchange Rates

International trade means selling goods and services to other countries (exports) and buying from them (imports). Countries trade because they differ in resources, skills and costs. Trade gives businesses bigger markets and cheaper inputs. It also brings more competition.

The balance of payments is a record of all money flowing into and out of a country over a period. It has two main parts. The current account records trade in goods (visible), trade in services (invisible), income from investments and transfers. The capital and financial account records investment, loans and other capital flows. In theory the whole balance of payments balances. In exam questions, a current account deficit means a country buys more from abroad than it earns from abroad on current items.

An exchange rate is the price of one currency in terms of another. If the dollar strengthens against the euro, one dollar buys more euros. Rates can be floating (set by supply and demand in the market), fixed (set by the government or central bank) or managed. A rate rises when demand for the currency rises, for example when foreigners want the country's exports or its higher interest rates.

Exchange rates affect business directly. A stronger home currency makes exports dearer for foreign buyers and imports cheaper at home. This hurts exporters and helps importers. A weaker home currency does the reverse. Firms also face transaction risk: the rate may move between agreeing a deal and being paid.

Trade barriers protect home industries. Tariffs are taxes on imports. Quotas limit the quantity of imports. Subsidies help domestic producers. Embargoes ban trade altogether. Non-tariff barriers include strict standards and slow paperwork. Protectionism can save jobs and protect new industries, but it raises prices, reduces choice and invites retaliation.

Trading blocs are groups of countries that agree to trade more freely with each other. Types run from a free trade area (no tariffs between members), to a customs union (a common external tariff as well), to a common market (free movement of labour and capital too), to economic union (a shared currency or policies). Members gain bigger markets and lower costs. Outsiders face barriers, and members give up some control over policy.

Globalisation is the growing links between national economies through trade, investment, technology and people. It lets firms source cheaply, sell widely and locate anywhere. It also exposes them to foreign competitors, currency swings, political risk and criticism over labour and environmental standards.

Key formulas to remember

Balance of payments identity: Current account + Capital and financial account ≈ 0 (after balancing items); Overall, payments in equal payments out. A current account deficit is financed by a capital account surplus, such as borrowing or foreign investment.
Current account: Trade in goods + Trade in services + Income + Transfers; Goods are visible trade; services are invisible trade.
Converting currency: Foreign amount = Home amount × Rate (foreign per 1 home) ; Home amount = Foreign amount ÷ Rate; Check which currency is quoted per one unit of the other. Multiply or divide accordingly.
Effect of currency strength: Stronger home currency → exports dearer, imports cheaper ; Weaker home currency → exports cheaper, imports dearer; Assumes other things equal. The actual effect on volumes depends on demand elasticity.

How to solve International Trade and Exchange Rates questions

Use this method for any question on trade, exchange rates, barriers or blocs.

1Read the question and identify the type: balance of payments, exchange rate, trade barrier, trading bloc or globalisation.
2Identify the business or country involved and whether it is an exporter, importer, borrower or investor.
3For exchange rates, decide the direction of the move: is the home currency stronger or weaker?
4Work out the effect on prices: exports become dearer or cheaper for foreigners, and imports dearer or cheaper at home.
5For numbers, check how the rate is quoted, then multiply or divide. Check the answer makes sense.
6For barriers and blocs, list the winners and losers: domestic producers, consumers, foreign firms, governments.
7Match your answer to the question verb and the number of options required, then check each option against the conditions.
8Eliminate options that reverse the direction of the effect. This is the most common trap.

Quickest way: Direction-of-effect shortcut

When to use it: Use it for multiple choice questions on exchange rate effects and trade barriers when time is short.

Mark the home currency as stronger or weaker.
Stronger: exporters lose, importers gain. Weaker: exporters gain, importers lose.
For tariffs and quotas: domestic producers gain, consumers and foreign producers lose, the government gains only from tariffs.
For blocs: members trade freely inside, outsiders face a barrier.
For rate conversions: if you are converting into the currency that is quoted per one home unit, multiply; otherwise divide.
Pick the option that matches, and reject any that reverse the direction.

Common mistakes in International Trade and Exchange Rates

Saying a strong currency helps exporters.
Strong sounds good, so students assume it benefits everyone.
Fix: Remember a strong home currency makes exports dearer abroad. It helps importers, not exporters.
Multiplying when you should divide in currency conversion.
Students do not check how the rate is quoted.
Fix: Write the rate as 'X units of foreign per 1 home' first. Foreign amount = home × rate. Then sense-check: does the result look larger or smaller as expected?
Confusing tariffs and quotas.
Both restrict imports, so they seem identical.
Fix: A tariff is a tax on imports and raises government revenue. A quota is a limit on quantity and raises no tax revenue.
Mixing up a free trade area, a customs union and a common market.
The names sound similar and the stages build on each other.
Fix: Free trade area: no internal tariffs. Customs union: adds a common external tariff. Common market: adds free movement of labour and capital.
Treating a current account deficit as automatically bad.
The word deficit sounds negative.
Fix: State the facts. A deficit means more spent abroad than earned. It may be financed by investment inflows and can be sustainable for a time. It is a concern if it persists and relies on borrowing.
Listing only advantages of protectionism or globalisation.
Students learn one side and stop.
Fix: Give both sides and tie them to the business in the question.

Worked examples

Example 1

A company in the UK sells goods to the US priced in pounds. The pound strengthens against the dollar. Which ONE of the following is the most likely effect on the company? A) US customers find the goods cheaper. B) US customers find the goods dearer, so demand may fall. C) The company's UK costs rise automatically. D) The goods become cheaper to import into the UK.

Show the solution

The exporter is UK-based and prices in pounds.
The pound is stronger, so a US buyer needs more dollars to buy each pound.
The goods are therefore dearer in dollars for US customers.
Dearer goods usually reduce demand, depending on elasticity.
Option A reverses the effect. Option C is not caused by the rate. Option D concerns imports, not this company's exports.

Answer: B

Example 2

A US firm buys machinery from a eurozone supplier for €240,000. The exchange rate is $1 = €0.80. What is the cost in dollars, and what happens to that cost if the dollar weakens to $1 = €0.75?

Show the solution

The rate is quoted as euros per 1 dollar, so dollars = euros ÷ rate.
At €0.80 per $1: $240,000 ÷ 0.80 = $300,000. Wait: €240,000 ÷ 0.80 = $300,000.
At €0.75 per $1: €240,000 ÷ 0.75 = $320,000.
The difference is $320,000 − $300,000 = $20,000 more.
A weaker dollar buys fewer euros, so imports priced in euros become dearer.

Answer: The cost is $300,000 at the original rate and rises to $320,000 after the dollar weakens, an increase of $20,000.

Exam tips

Always state the direction first: stronger or weaker home currency. Most marks are lost by reversing it.
In number entry, check how the rate is quoted and do a sense check before you type.
For multiple response questions, select exactly the stated number and test each option against the exact definition, such as free trade area versus customs union.
Link your answer to the business in the scenario: exporter, importer, or firm with foreign borrowings.
Learn the terms precisely: tariff, quota, subsidy, embargo, and the stages of trading blocs.

International Trade and Exchange Rates: frequently asked questions

What is the balance of payments in ACCA BT?

It is a record of all money flowing into and out of a country over a period. The current account covers trade in goods and services, income and transfers. The capital and financial account covers investment and loans.

How do exchange rates affect business?

They change the price of exports and imports and the value of foreign income and debts. A stronger home currency hurts exporters and helps importers. A weaker one does the opposite. Firms also face the risk of rates moving between a deal and payment.

What are the advantages and disadvantages of tariffs and quotas?

They protect domestic producers and jobs, and tariffs raise government revenue. They also raise prices, reduce consumer choice and can cause other countries to retaliate. Foreign producers lose sales.

How do trading blocs affect businesses?

Members gain access to a larger market with fewer or no trade barriers, which can lower costs and support growth. Firms outside the bloc may face tariffs and stronger competition. Members also accept shared rules and lose some policy freedom.
