The FIs constructed with reference to an underlying asset are called derivatives as their price is derived from the price that develops on the physical market. This relationship, however, is neither clear-cut nor simple. It is not clear-cut as the physical price does influence the derivative; however, in return, the price of the FI has an impact on the physical markets.
