Chicago Close

Corn: Sep 11 corn closed at USD7.01 1/4, up 10 1/2 cents; Dec 11 corn closed at USD6.85, up 6 1/2 cents. Dec corn was up 68 1/2 cents on the week. As with soybeans the corn market was adding some pre-weekend risk premium on fears that a prolonged heatwave would damage corn at the pollination stage, the most sensitive period for determining yields. Strong crude oil and a weaker US dollar also added some support. The dollar was under pressure on talk that Moody's and S&P might downgrade America's credit rating.
Wheat: Sep 11 CBOT wheat closed at USD6.94 3/4, down 12 1/4 cents; Sep 11 KCBT wheat closed at USD7.64 1/2, down 3/4 cent; Sep 11 MGEX wheat closed at USD8.23 3/4, down 5 1/4 cents. On the week overall Sep CBOT wheat closed up 43 1/2 cents, Sep 11 KCBT wheat closed up 37 1/4 cents and Sep 11 MGEX wheat closed up 6 3/4 cents. News that Russia had again bought wheat from Russia at far cheaper levels than other origins depressed the market today. US wheat was around USD35/tonne dearer than the winning Russian bids on an FOB basis, and in the case of Egypt there is then dearer freight to add on top.
