Know How Foreign Exchange Rates Are Determined

Do you want to know how foreign exchange rates are determined? If so, keep reading!

The foreign exchange market is very large, with trillions of dollars being exchanged on a daily basis. In order to have an idea about what happens in this market, it is important to understand how foreign exchange rates are determined and how they work.

The supply of currencies depends on several factors such as:

  1. How many units of a certain currency do we have?
  2. What does each unit cost?
  3. Who wants it?
  4. Will anyone sell it to me at this price?
  5. Is there a buyer willing to pay more than I want for it?
  6. What would happen if I bought more units than there were buyers willing to sell them at this price?

Overall, foreign exchange rates are determined by the supply and demand of global currency pairs. When the demand for one currency is greater than another, its value rises. The opposite is also true, meaning that if there is more demand for a different currency than another, then its value will fall.
