Factors Affecting the Market

Currency prices are affected by a variety of economic and political conditions, most importantly interest rates, inflation and political stability. Moreover, governments sometimes participate in the Forex market to influence the value of their currencies, either by flooding the market with their domestic currency in an attempt to lower the price, or conversely buying in order to raise the price. This is known as Central Bank intervention. Any of these factors, as well as large market orders, can cause high volatility in currency prices. However, the size and volume of the Forex market makes it impossible for any one entity to «drive» the market for any length of time.
Another factor affecting the market, with an effect as important as the other factors mentioned above, is the news. Once released, the news have a direct outcome on the currency price as per news are always directly related to the economic stability of the market.
