December wheat opened 13 cents lower on the day at 560 and established an early range of 558 to 572. The wheat market opened lower following a selloff in crude oil and stocks. Traders reported that early volume was good. Demand is still said to be good on export markets with Black Sea and UK origin being cited as major factors by cash market sources. The Baltic Dry Sea Freight Index fell again today. This is contributing to export sales, but shippers are also citing fears of potential declines in grain shipping business as well as fears of defaults by customers that bought at higher levels.
