What are foreign currency exchange rates?
Let’s start with a definition of foreign currency exchange rates. Simply put, foreign currency exchange rates are what it costs to exchange one country’s currency for another country’s currency. For example, if you go to England on vacation, you will have to pay for your hotel, meals, admissions fees, souvenirs and other expenses in British pounds. Since your money is all in US dollars, you will have to sell some of your dollars to buy British pounds.
Let’s assume that you have decided to take a trip to England. Before you leave, you go to your bank and buy $1,000 worth of British pounds. If you get 565.83 British pounds (£565.83) for your $1,000, each dollar is worth .56583 British pounds. This is the exchange rate for converting dollars to pounds.
After spending a few days in England, you realize that £565.83 won’t be enough to cover all of your expenses. So you go to a bank in England and buy another $1,000 worth of British pounds. This time, however, you get only £557.02 for your $1,000. The exchange rate for converting dollars to pounds has dropped from .56583 to .55702. This means that US dollars are worth less compared to the British pound than they were before you left on vacation.
When you arrive home, you still have some British pounds left. So you go to your bank and use your remaining £100 to buy US dollars. If the bank gives you $179.31, each British pound is worth 1.7931 dollars. This is the exchange rate for converting pounds to dollars.
