Currency Exchange FAQ - Common Questions About Exchange Rates

What is an exchange rate?

An exchange rate is the value of one currency expressed in terms of another currency. For example, if the USD to EUR exchange rate is 0.85, it means 1 US Dollar equals 0.85 Euros. Exchange rates fluctuate constantly based on market conditions, economic factors, and supply and demand.

How often do exchange rates change?

Exchange rates change continuously throughout the day as currency markets are open 24/5 (Monday through Friday). Major changes typically occur during market hours when banks and financial institutions are actively trading. At BuckRates.com, we update our rates three times a day (06:00, 13:00, and 20:00 UTC) to provide you with current interbank middle rates.

What is the difference between buying and selling rates?

The buying rate (bid) is what banks pay when you sell foreign currency to them, while the selling rate (ask) is what you pay when buying foreign currency. The difference between these rates is called the "spread" and represents the bank's profit margin. Our rates show the middle rate, which is the average of buying and selling rates.

Why do exchange rates fluctuate?

Exchange rates fluctuate due to various factors including:

• Economic indicators: GDP growth, inflation, employment data
• Interest rates: Higher rates typically strengthen a currency
• Political stability: Political events can impact currency values
• Market sentiment: Investor confidence and speculation
• Trade balances: Import/export relationships between countries
• Central bank policies: Monetary policy decisions
