Forex market

Unlike the equity market - where investors often only trade with institutional investors (such as mutual funds) or other individual investors - there are additional participants that trade on the forex market for entirely different reasons than those on the equity market. Therefore, it is important to identify and understand the functions and motivations of the main players of the forex market.
Governments and Central BanksArguably, some of the most influential participants involved with currency exchange are the central banks and federal governments. In most countries, the central bank is an extension of the government and conducts its policy in tandem with the government. However, some governments feel that a more independent central bank would be more effective in balancing the goals of curbing inflation and keeping interest rates low, which tends to increase economic growth. Regardless of the degree of independence that a central bank possesses, government representatives typically have regular consultations with central bank representatives to discuss monetary policy. Thus, central banks and governments are usually on the same page when it comes to monetary policy.
Central banks are often involved in manipulating reserve volumes in order to meet certain economic goals. For example, ever since pegging its currency (the yuan) to the U.S. dollar, China has been buying up millions of dollars worth of U.S. treasury bills in order to keep the yuan at its target exchange rate. Central banks use the foreign exchange market to adjust their reserve volumes. With extremely deep pockets, they yield significant influence on the currency markets.
