December corn was down 6 cents late in the overnight trade. Outside markets look weak as a lack of new news from Washington on the debt ceiling and a stronger US dollar are seen as negative forces for most commodity markets. While there are plenty of reports which suggest that the pollination weather in July was abnormal enough to trigger a reduction in yield for most Midwest locations, the emergence of rain and cooler weather to stem losses and the outlook for milder weather into mid-August for the Midwest has helped spark the recent selling. While there are potential supply issues ahead, traders suggest that the USDA may not pick up all of these pollination problems for the upcoming August production report. In addition, the market is struggling with demand issues as well. A surge in wheat production from Europe and the Black Sea is expected to eat into export demand for corn and it is rare that Russia wheat is trading near or even under US corn so feedwheat demand is expected to be stronger than normal. US corn export premiums at the gulf yesterday were down 4-5 cents which added to the negative demand tone. The market closed lower on the session yesterday but once again had some late buying to bounce off of the lows. An improved weather outlook for the next few weeks and hopes for some rain in the next week for the dry areas of the south helped to pressure. The outlook for southern and Eastern Corn Belt areas to get at least some rain plus active rain for the northern Midwest helped spark selling. A bounce in the US dollar and demand concerns added to the negative tone. Weekly ethanol data Wednesday was sluggish and weekly export sales news yesterday was also slow for corn as global wheat prices are cheap relative to corn. Net weekly export sales for corn, came in at 331,500 metric tonnes for the current marketing year and 153,400 for the next marketing year for a total of 484,900 which was below trade expectations. Cumulative new crop corn sales stand at 15.6% of the USDA forecast versus a 5 year average of 8.4%. Sales of 699,000 metric tonnes are needed each week to reach the USDA forecast. The International Grain Council pegged world corn production at a record high 859 million tonnes from 858 million as last month's estimate and from 827 million tonnes last year. Traders continue to discuss news this week that Brazil will continue to import ethanol in the months ahead and may end up importing near 650 million liters for the year ending March. This represents about 4.1 million barrels which is about 2/3rds of one week production in the US and represents near 62 million bushels of corn.
