How are currency exchange rates determined?

Exchange rates fluctuate continuously based on global foreign exchange market supply and demand, central bank interest rates, inflation, and macroeconomic events.

What is the difference between buy rate and sell rate?

The buy (bid) rate is the price a bank pays to buy foreign currency from you, while the sell (ask) rate is the higher price they charge when selling foreign currency to you. The difference is the bank spread.

How do I calculate bank markup fees on currency conversions?

Subtract the bank's offered rate from the mid-market interbank rate, divide by the mid-market rate, and multiply by 100 to find the hidden percentage markup.

Which currencies are most traded globally?

The most traded currencies are the US Dollar (USD), Euro (EUR), Japanese Yen (JPY), British Pound (GBP), Australian Dollar (AUD), and Canadian Dollar (CAD).
