Initial public offering of the standard granulated iron ore Salam contracts of Golgohar Mining and Industrial Company was inaugurated in Iran Mercantile Exchange (IME) in July 2014 and all the issues pertinent to the registry, clearing, settlement, and delivery of these contracts are implemented in CSDI using MCNetclear. The relevant secondary trades started from August 2 and will proceed till July 13th 2015. CSDI plays a very crucial role here due to the fact that the tasks of handling four main activities including registry, clearing, settlement, and delivery are done by CSDI. The registry of standard granulated iron ore Salam contracts in the post-trade system is a pre-condition to the secondary trade. Simply put, these trades will be cleared and settled in the net based model by CSDI and it is beneficial for both investors and brokerage houses in this regard.
