(4)In order to ensure that the price discovery process is not unduly influenced by the existence of a position and to identify the build-up of concentrations of positions that could result in price distortion, market manipulation or other abusive trading practices, trading venues should be aware of large positions held by end position holders and parent undertakings in physically settled commodity derivatives and the reasons for holding those positions. As the actual supply of the underlying physical commodity is restricted to a finite supply, physically settled commodity derivatives are more susceptible to disorderly trading practices such as market squeezes or market cornering where counterparties would make use of a dominant position to secure the price of a commodity derivative, or of the underlying commodity, at an artificial level. Therefore, large positions should be identified in commodity derivatives that are physically settled by design as well as in commodity derivatives that can be physically settled at the option of the buyer or the seller.
