A floating exchange rate is a system in which the value of a currency is allowed to fluctuate according to the foreign exchange market. This is primarily determined by factors such as interest rates, inflation, and economic stability. Unlike a fixed exchange rate, where a currency's value is pegged to another currency or a basket of currencies, a floating rate can change frequently, reflecting real-time economic conditions.
For example, if the demand for the US dollar increases due to higher interest rates in the United States, its value against other currencies, such as the euro, will rise. This adjustment represents the market's perception of the relative economic conditions in the two regions. Floating exchange rates can offer flexibility and help absorb shocks in the economy, but they can also lead to volatility, as sudden market movements can impact value significantly.
