Corn The old crop corn market did not suffer any big changes during the last week. There were a couple of sellers still willing to see demand out of Upriver ports for August/September shipments. Open prices stand at -35 CZ, but selling ideas are close to -40 CZ. There is little demand for spot shipments as most buyers already have covered their positions and are currently looking for October/November and December shipments.Only a couple trades -- not more than 0.07 MMT -- during the week in review. In our last report, as much as 0.25 MMT were reported. It now seems that demand will not appear -- at least not at these premiums. August shipment is mostly done, and sellers now are looking for 15 August or September shipments.Panamaxes loadi...
