Review Questions

  • How does the Foreign Exchange Market facilitate international trade and investment?
    • The Foreign Exchange Market facilitates international trade and investment by allowing businesses and individuals to exchange currencies easily. This is crucial for companies that operate globally and need to convert their domestic currency into foreign currency to pay for goods or services. By providing a platform for currency conversion, the FOREX market ensures that transactions can occur efficiently, enabling smoother cross-border trade and investment flows.
  • Discuss how central banks impact the Foreign Exchange Market and the implications of their actions on exchange rates.
    • Central banks impact the Foreign Exchange Market primarily through monetary policy decisions, such as setting interest rates and engaging in open market operations. For instance, if a central bank raises interest rates, it may attract foreign capital seeking higher returns, leading to an appreciation of the domestic currency. Conversely, when a central bank lowers interest rates, it could result in depreciation as capital flows out. These actions can create volatility in exchange rates and affect international trade competitiveness.
  • Evaluate the role of speculation in the Foreign Exchange Market and its effects on currency stability.
    • Speculation plays a significant role in the Foreign Exchange Market as traders buy and sell currencies based on anticipated movements in exchange rates. While speculation can provide liquidity and help determine fair value for currencies, it can also lead to increased volatility and instability. For example, if speculators believe a currency will depreciate, they may sell it en masse, causing rapid declines in its value. This speculative behavior can create short-term fluctuations that might not reflect fundamental economic conditions.
