The document provides a history of foreign exchange markets. It discusses how bartering led to the development of currency, and how coins and paper money emerged. Modern foreign exchange markets originated in 17th century London coffee houses. These markets grew significantly in the 1970s with the rise of interbank trading between commercial and investment banks. Electronic communications networks and the internet further accelerated growth and lowered transaction costs. Major currencies that are traded include the US dollar, euro, Japanese yen, and British pound. Factors like interest rates, inflation, and central bank policies influence exchange rates in both the short and long term.
