What are Currency Exchange Rates?

Currency exchange rates refer to the value of one currency compared to another. They fluctuate constantly based on various economic factors, such as inflation, interest rates, and political stability. For example, if the exchange rate for the US Dollar (USD) to the Euro (EUR) is 0.83, it means that 1 USD can be exchanged for approximately 0.83 EUR.

Factors Influencing Currency Exchange Rates

Several factors can impact currency exchange rates, including:

  1. Inflation: Higher inflation in a country can lead to a weaker currency, as the purchasing power of that currency decreases.
  2. Interest Rates: When a country’s interest rates rise, its currency often becomes more attractive to investors, causing its value to increase.
  3. Economic Performance: A country with a strong economy and stable growth is likely to have a stronger currency compared to countries with weaker economic performance.
  4. Political Stability: Political uncertainty or instability in a country can negatively impact its currency’s value.
  5. Supply and Demand: The basic laws of supply and demand also apply to currencies. If there is a high demand for a particular currency, its value will increase.
