The primary factor driving currency exchange rate fluctuations is changes in interest rates. Interest rates set by central banks, such as the Federal Reserve in the U.S. or the European Central Bank in the Eurozone, directly influence the value of a currency. Higher interest rates typically attract foreign capital, as investors seek to take advantage of higher returns on investments that denominated in that currency. This increased demand for the currency can lead to its appreciation. Conversely, lower interest rates may result in capital outflows and a depreciation of the currency.

While government policy changes, shifts in investor sentiment, and economic performance indicators all have roles in affecting currency values, they often interplay with interest rates. For instance, a government policy that leads to changes in interest rates can have a more pronounced effect on currency exchange rates than the policy itself. Similarly, shifts in investor sentiment may relate to perceptions about interest rate movements. Additionally, economic performance indicators can influence interest rates when they lead to central bank actions in response to inflation or growth forecasts. However, changes in interest rates are what directly dictate the flow of capital across borders, thus leading to significant fluctuations in currency exchange rates.
