Currency

Definition

Currency refers to the system of money in general use within a particular country or economic area. It serves as a medium of exchange, a unit of account, and a store of value, facilitating trade and economic interactions both domestically and internationally. The value of currency can fluctuate based on various factors, including supply and demand dynamics, interest rates, and economic policies, making it essential to understand its role in exchange rates, international trade, and capital flows.

Review Questions

• How does the value of currency influence exchange rates and what factors contribute to these fluctuations?
  • The value of currency directly affects exchange rates, as it determines how much of one currency can be exchanged for another. Factors such as inflation rates, interest rates, and economic stability influence these fluctuations. For instance, if a country's inflation rate is higher than that of other countries, its currency may depreciate relative to others. Additionally, supply and demand for the currency in the foreign exchange market play crucial roles in determining its value.
• In what ways do changes in government policies impact the foreign exchange market and consequently affect currency values?
  • Government policies such as changes in interest rates or fiscal stimulus can significantly impact the foreign exchange market. For example, if a government raises interest rates to control inflation, it could attract foreign investment seeking higher returns. This increased demand for the currency can cause its value to rise. Conversely, expansionary fiscal policies might lead to concerns about future inflation, potentially depreciating the currency. Thus, policy decisions have a ripple effect on currency values through investor perceptions and market reactions.
• Evaluate how real interest rates affect international capital flows and their subsequent impact on currency strength or weakness.
  • Real interest rates play a crucial role in determining international capital flows because higher real interest rates tend to attract foreign capital seeking better returns. This influx of capital can lead to an appreciation of the domestic currency as demand increases. Conversely, lower real interest rates may drive capital outflow as investors seek higher returns elsewhere, leading to currency depreciation. Thus, the relationship between real interest rates and capital flows significantly influences currency strength or weakness in the global market.
