December corn was down 6 3/4 cents late in the overnight session. Outside market forces look mixed to weak this morning, with lower trade for energy and metal markets and a firm tone to the US dollar late in the session. Continued talk of better than expected corn yields for Midwest producers plus increased harvest pressures expected in the next week or more due to dry weather are factors which have helped to pressure the market recently. Traders are also nervous that cheap feedwheat might have translated to slower feed demand for corn over the last quarter and a higher September 1st stocks number on Friday. This has helped keep the market in a long liquidation mode, as speculators have moved to the sidelines ahead of this report. Open interest is down 73,000 contracts since August 26th. Ideas that September 1st stocks (Friday morning) might be 40-50 million bushels above the recent USDA forecast of 920 million may have been one of the factors that caused the market to give back a big part of the early gains from yesterday. There is a wide range of estimates for the report, as feed and ethanol usage can be difficult to predict. December corn saw some early strong gains yesterday, but the market moved drifted well off of the early highs as the buying slowed later in the session. The surge higher in energy markets and a jump across the board in commodity markets helped spark the early strength, as there appeared to be fewer concerns over European economic woes. The corn harvest reached only 15% complete as of Sunday, which was lower than expected. South Korea bought 110,000 tonnes of corn, 55,000 tonnes of feedwheat and 55,000 tonnes of meal. The push back up through the 200-day moving average was seen as a technical factor helping to relieve fears of continued long liquidation selling from fund traders and speculators. Ideas that officials in Europe are working on measures to calm Euro debt issues helped support the across-the-board buying for commodity markets yesterday. South Korean feed millers have bought at least 12 cargoes (661,000 tonnes) of corn since September 20th.
