How Currency Exchange Rates Work
Exchange rates represent the price of one nation's currency in terms of another. These values are determined by the global Foreign Exchange (Forex) market, where traders, banks, and governments buy and sell currencies 24 hours a day. Factors such as interest rates, inflation, and geopolitical stability cause these rates to fluctuate constantly.
Floating vs. Fixed Exchange Rates
Most major currencies like the USD, EUR, and GBP have **floating rates**, meaning their value is determined by market demand. Some currencies, like the UAE Dirham (AED), use a **fixed rate** (pegged) system, tied directly to the value of the US Dollar to maintain stability for international trade.
Understanding the Mid-Market Rate
The "Mid-Market" rate is the midpoint between the buy and sell prices of two currencies. This is the rate global banks use when trading with each other. When you convert money at a bank or airport, they usually add a markup of 3% to 5%, which is why their rates are worse than the live rates shown here.
