DES MOINES, Iowa (Agriculture.com)--The CME Group wheat market took control of commodities trading Thursday, helping corn finish higher too.

The Dec. futures corn contract settled 7 3/4 cents higher at $7.98 1/2. Nov. soybean futures contract finished 1/2 of a cent lower at $17.47. Dec. wheat futures settled 23 1/2 cents higher at $9.10 1/2 per bushel. The Dec. soyoil futures contract finished $0.59 lower at $57.38. The Dec. soymeal futures contract ended $3.10 per short ton higher at $528.10.

In the outside markets, the NYMEX crude oil is $0.06 per barrel higher, the dollar is lower and the Dow Jones Industrials are 216 points higher.

Jack Scoville, PRICE Futures Group vice president, says wheat is up on news Ukraine could stop exports in a month or so, once the surplus is gone.  

Ukraine stated that they want to make sure the domestic market there has plenty of wheat and are ready to shut it down.  Russia still says no, but said they might buy what is available from the Kazaks to cover. So, this implies higher prices too.  

Corn is higher, due to Thursday's announcement of an 'unknown' purchasing 217,000 tons of corn for 2012-14 delivery, he says. This is the second sale for the next crop year in a week.  

"Plus, corn is going along with wheat. Meanwhile, soybeans are a mess, as weak cash markets keep futures weak. But, buying is coming in spurts with the grains. Seems like mostly specs both ways. My commercial side is quiet right now and Brazil is trying to sell rallies in beans, but is quiet in corn right now,' Scoville says.
