Review Questions

• How does central bank intervention affect the stability of a country's currency?
  • Central bank intervention plays a crucial role in maintaining the stability of a country's currency by mitigating excessive fluctuations in its value. When a central bank steps in to buy or sell its own currency, it can counteract market forces that may lead to rapid appreciation or depreciation. This stability helps create a favorable environment for trade and investment, allowing businesses and consumers to plan better for the future.
• Evaluate the potential consequences of prolonged central bank intervention in foreign exchange markets.
  • Prolonged central bank intervention can lead to several consequences. While it may provide short-term stability for the currency, it can also result in the depletion of foreign exchange reserves if the intervention is significant. Additionally, continuous market manipulation might lead investors to question the credibility of the central bank, possibly resulting in increased volatility once intervention ceases. Lastly, it can also create dependency on interventions rather than addressing underlying economic issues.
• Assess how central bank intervention interacts with global economic conditions and its implications for international trade.
  • Central bank intervention is closely intertwined with global economic conditions as fluctuations in major economies can impact exchange rates significantly. When one country intervenes, it can lead to ripple effects in other nations' currencies, influencing competitive advantages in international trade. For example, if a central bank devalues its currency through intervention, its exports may become cheaper and more attractive to foreign buyers. However, this strategy can also provoke retaliatory measures from other countries, leading to tensions in international trade relationships.
