An **exchange rate** is the price of one currency expressed in another currency. It shows how much of one currency you receive for one unit of another currency. Exchange rates constantly change due to supply and demand in the foreign exchange market.

The exchange rate determines how many foreign products or investments you can buy.

 

When many people want to exchange euros for dollars, the value of the dollar rises relative to the euro. Economic growth, interest rate differences and political stability can influence the exchange rate. For investors, the exchange rate is important when investing in foreign shares or bonds, because changes in currency value affect the final return.

 

 

 

 

 

 

 

 

 

Short example:

 

Suppose the exchange rate is €1 = $1.10. This means that for €1.00 you receive approximately $1.10.

 

If you exchange €1,000, you receive $1,100.

 

If the exchange rate later falls to €1 = $1.00, you receive only $1,000 for €1,000. Changes in the exchange rate can therefore affect the value of international investments.
