Corn futures were caught off-guard by a surprise hike to corn yield on Friday, as contracts closed with losses of 19 to 21 cents in the front months. December pulled nearly a dime off the limit losses, but still saw a weekly loss of 18 cents. Deferred contracts were down 3 to 8 cents on Friday. The CmdtyView national average Cash Corn price was down 22 3/4 cents at $4.39.
Crop Production data from this morning showed US corn yield at 181.2 bpa, up 2.7 bpa from the September report. That took the production total 234 mbu higher to 16.034 bbu and was well above trade estimates.
