a) Impact of changes in exchange rates and the possible effects on: o the current account and the balance of payments o economic growth; firms o employment/unemployment o the rate of inflation o FDI flows
Changes in exchange rates significantly impact macroeconomic objectives and firm behaviour. A depreciation typically improves the current account of the balance of payments by making exports more competitive and imports more expensive. This boost in net exports can stimulate economic growth and increase employment in export-driven sectors. However, dearer imports can cause cost-push inflation, squeezing firms' profit margins if they rely on imported raw materials. Furthermore, a weaker currency might attract Foreign Direct Investment (FDI) flows as domestic assets become cheaper for foreign investors, though severe exchange rate volatility can deter long-term investment by increasing uncertainty for multinational corporations.
b) The Eurozone
The Eurozone is a monetary union of EU member states that use the euro as their sole currency. Regarding exchange rate changes, Eurozone membership means individual countries, like Italy, cannot independently devalue their currency to manage economic shocks or boost competitiveness. The European Central Bank sets a single monetary policy for the bloc. While this single currency eliminates exchange rate uncertainty and transaction costs between members, boosting intra-Eurozone trade, it removes a key macroeconomic adjustment tool. If a member faces a downturn, it cannot use exchange rate depreciation to stimulate export demand, relying instead on internal devaluation, such as lowering wages, to restore its international competitiveness.
Your focus
- Analyse the theoretical effects of currency appreciation and depreciation on the current account and domestic inflation.
- Evaluate the consequences of exchange rate volatility for economic growth, employment levels, and firm profitability.
- Assess the relationship between exchange rate movements and the volume of Foreign Direct Investment entering or leaving an economy.
Show all 6 objectives
- Define the Eurozone and explain its function as a monetary union.
- Analyse the benefits of eliminating exchange rate fluctuations between member states.
- Evaluate the macroeconomic consequences for a country that cannot independently change its exchange rate.

Marking Points
- Analyse how a depreciation of the domestic currency can lead to an improvement in the current account balance, assuming the Marshall-Lerner condition is met.
- Evaluate the impact of an appreciation on economic growth, noting that while export volumes may fall, cheaper imported capital goods can boost long-term productivity for firms.
- Explain the transmission mechanism from a weaker exchange rate to higher domestic inflation via increased import prices (cost-push inflation).
- Discuss how exchange rate movements influence FDI flows, highlighting that a depreciated currency makes domestic assets cheaper for foreign buyers.
- Assess the effect of exchange rate fluctuations on employment, particularly the potential for job creation in export-oriented industries during a depreciation.
- Identify the Eurozone as a monetary union sharing a single currency and central bank.
- Explain that Eurozone members cannot independently alter their exchange rates to manage economic shocks.
- Recognise that a single currency eliminates exchange rate risk and transaction costs for trade between member states.
- Evaluate the inability to use currency depreciation to boost exports during a recession as a significant disadvantage.
Examiner Tips
- 💡Always use the acronym SPICED (Strong Pound Imports Cheap Exports Dear) to quickly determine the initial price effects of an exchange rate appreciation.
- 💡In extended responses, evaluate the impact of exchange rate changes by considering the price elasticity of demand for imports and exports (Marshall-Lerner condition).
- 💡Link exchange rate movements explicitly to firms' costs and revenues, especially for businesses that import raw materials or export finished goods.
- 💡When evaluating the impact of exchange rates, contrast the policy options of a Eurozone member with those of a country with a floating national currency.
- 💡Use the concept of internal devaluation (lowering domestic prices and wages) as the alternative to currency depreciation for Eurozone members.
- 💡Remember that while intra-Eurozone trade has no exchange rate risk, the euro still fluctuates against other global currencies like the US dollar.
Common Mistakes
- Assuming a depreciation immediately improves the current account; correct this by applying the J-curve effect, which shows a short-term worsening before long-term improvement.
- Confusing the impact of exchange rates on inflation; remember that an appreciation typically reduces inflationary pressure by making imports cheaper, not more expensive.
- Stating that a strong currency is always beneficial for an economy; correct this by explaining that while it lowers import costs, it harms export competitiveness and can increase unemployment in manufacturing.
- Confusing the Eurozone with the European Union; correction: The EU is a political and economic union, whereas the Eurozone specifically refers to the subset of EU countries that use the euro.
- Assuming individual Eurozone countries can set their own interest rates; correction: The European Central Bank sets a single interest rate for the entire Eurozone.
- Believing Eurozone countries can devalue their currency to boost exports; correction: Member states share the euro and cannot independently devalue it; they must use internal devaluation instead.
