In the article the author presents the importance of unlisted derivates in the financial market. The increasing volatility of basic prices of financial instruments (foreign exchange rates, interest rates and stock exchange indexes) is a major factor in the increase in sales of the derivates and makes business entities protect themselves against a financial risk. Simultaneously, it motivates business entities to take speculative action in order to make a profit. These are two factors in the derivates creation and development. The main reason why the interest in derivates has been growing is that the unlisted market was faced with obstacles related to the prediction of future changes of interest rate and foreign exchange rate. Financial activity was riskier and riskier. Moreover, mainly speculative dealings of national banks with foreign banks are carried out in the unlisted derivates market. Thus, banks provide financial markets liquidity.
