CME Group, a financial markets operator, is designing a new Black Sea wheat futures contract to follow the prices of wheat in Romania and Bulgaria. This contract will be based on an index of export prices for 12.5% protein wheat in the 'CVB' zone, which includes the Romanian port of Constanta and the Bulgarian ports of Varna and Burgas. The product will be cash-settled, priced in U.S. dollars, and traded in lots of 50 metric tons. It is expected to be introduced in time for the summer harvest.
