In multiple contexts, it’s important to shape. Currently, consumers come into contact with currency exchanges while traveling. To convert their home currency to the currency of the country they wish to fly to, they go to a bank or currency exchange bureau.
Consumers may also purchase goods in a foreign country or via the Internet with their credit card, in which case they will find that the amount they paid in the foreign currency will have been converted to their home currency on their credit card statement.
Although each such currency exchange is a relatively small transaction, the aggregate of all such transactions is significant. Businesses typically have to convert currencies when they conduct business outside their home country. They export goods to another country and receive payment in the currency of that foreign country, then the payment must often be converted back to the home currency.
