The grains spent the overnight trade on the higher side, and that strength is expected to spill into Thursday's trading session.

Early calls for the grains are corn 4-6 cents higher, soybeans 9-11 higher and wheat 6-9 higher, according to private sources. Overnight trading found March corn trading 3 1/2 cents higher at $6.04 3/4 per bushel, while January soybeans were 9 cents higher at $11.40 1/4 and March wheat was 7 1/2 cents higher at $6.03 1/4, according to Barchart.com.

It looks to be another volatile trading day Thursday, says ICAP Energy LLC Derivatives Manager Scott Shellady. Wednesday's action by world banks, including the U.S. Federal Reserve, to lower a key interest rate makes the U.S. Dollar cheaper, Shellady says, and heightens the grains' focus on the U.S. Dollar index moving forward.

"We need to keep an eye on dollar strength/weakness as we lurch from headline to headline," Shellady said Thursday morning.
