After two straight weeks lower, corn futures have moved back up in Chicago. The December/23 ended last Friday, September 8, quoted at 483.75 cents/bu, an appreciation of 0.5% in the weekly comparison.


American crop condition: According to the USDA crop follow-up report, 53% of corn crops were rated good/excellent (B/E) on Sept. 3, down three percentage points from a week earlier, down 1 point from the same period last year, and 7 points below the 5-year average. A drop in crops classified as good/excellent was expected, but the drop was 1 point higher than the agents' expectation. The US crop is advancing as expected.
