Summary and Exam Tips for Exchange Rates
Exchange Rates is a subtopic of International Trade and Globalisation, which falls under the subject Economics in the Cambridge IGCSE curriculum.
The foreign exchange rate is the value of one currency expressed in terms of another, such as £1 = $1.2. This rate is crucial for international trade and investment. The exchange rate is determined by the demand and supply of a currency in the foreign exchange market. For instance, demand for the pound sterling arises when foreign consumers purchase UK goods or invest in the UK, while supply occurs when UK consumers buy foreign goods or invest abroad.
Fluctuations in exchange rates can be caused by factors such as inflation, changes in interest rates, foreign direct investment (FDI), speculation, and government intervention. A rise in demand or a fall in supply of a currency leads to an appreciation, while the opposite causes depreciation.
The consequences of exchange rate fluctuations include changes in import and export prices, affecting trade balances. A floating exchange rate is determined by market forces and can lead to automatic stabilization but also uncertainty. In contrast, a fixed exchange rate is controlled by the central bank, providing stability but less flexibility.
Exam Tips
-
Understand Key Definitions: Be clear on terms like foreign exchange rate, appreciation, and depreciation. These are fundamental to answering questions on exchange rates.
-
Demand and Supply: Focus on how changes in demand and supply affect exchange rates. Remember, increased demand or decreased supply leads to currency appreciation, and vice versa.
-
Causes and Consequences: Be prepared to explain how factors like inflation, interest rates, and FDI influence exchange rates and their subsequent impact on trade balances.
-
Floating vs. Fixed Rates: Know the advantages and disadvantages of both systems. Floating rates offer flexibility but can cause uncertainty, while fixed rates provide stability but limit policy flexibility.
-
Use Real-World Examples: Illustrate your answers with examples of how countries manage their exchange rates, such as the role of central banks in maintaining fixed rates.
