The USDA on Tuesday forecast the US soyabean harvest as the largest ever, while the corn crop was seen at the third largest on record. The agency also bumped up global stocks of corn, soyabeans and wheat to record highs. Chicago Board of Trade December corn rose 2-1/2 cents, or 0.7 percent, to $3.61-1/2 a bushel by 11:56 am CST (1756 GMT) while January soyabeans gained 2 cents, or 0.2 percent, to $8.57-1/2 a bushel. CBOT December wheat was unchanged at $4.90-3/4 a bushel.
"The little bit of support is from a technical rebound due to the increase in short positions that we saw yesterday in open interest," said Terry Reilly, senior commodities analyst with Futures International. As futures prices dropped on Tuesday, open interest grew, according to exchange data. The day's trading volume, meanwhile, was near a record high in several commodities, in stark contrast to Wednesday's slow trade. US wheat export demand remained limited by ample supplies of less expensive grain elsewhere in the world.
There were no offers of US wheat in the latest international tender by Egypt's state buyer GASC, its second tender in as many days. The market largely shrugged off a trucker strike in Brazil as impacts on corn and soyabean shipments to export terminals was very limited.
