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, crucial for currency conversion in international trade. Exchange rates are expressed as currency pairs, such as USD/GBP, where the base currency is USD and the price currency is GBP. In a floating exchange rate system, rates are determined by demand and supply in the FOREX market. An increase in demand or decrease in supply of a currency leads to appreciation, while the opposite causes depreciation. Factors influencing currency demand and supply include foreign demand for exports, domestic demand for imports, foreign direct investment, portfolio investment, remittances, speculation, inflation rates, interest rates, growth rates, and central bank interventions. Understanding these factors helps in predicting currency movements and their impact on the global economy.
