What is the main or major purpose of this foreign exchange market? Well the main reason for the foreign exchange market is to aid in the international trade and investments. This market is the one that allows many of the businesses today to change one currency into another currency for the business that they need to accomplish to be profitable. Let’s take for example a US business that needs to import goods from England and they need to pay for the goods in British pounds even though the business receives its main income in US dollars. This market regulates the rates and how best exchange rates is being sold and exchanged. This is one of the main reasons why we need foreign exchange and so the foreign exchange market is here.

The foreign exchange market is just one of those things that work in the background of our lives yet it ensures that everything around us moves smoothly.
