Summary and Exam Tips for Exchange Rates
Exchange Rates is a subtopic of The Global Economy, which falls under the subject Economics in the IB DP curriculum. An exchange rate is the value of one currency in terms of another and is crucial for currency conversion in international trade. Exchange rates are expressed as currency pair quotations, such as USD/GBP, where the base currency is the first currency and the price currency is the second. In a floating exchange rate system, the value of currencies is determined by the forces of demand and supply in the FOREX market. An increase in demand or a decrease in supply of a currency leads to its appreciation, while a decrease in demand or an increase in supply leads to depreciation. Factors affecting currency demand and supply include foreign demand for exports, domestic demand for imports, foreign direct investment, portfolio investment, remittances, speculation, relative inflation rates, interest rates, growth rates, and central bank intervention. Understanding these factors is essential for analyzing currency fluctuations and their impact on the global economy.
