The November WASDE showed corn ending stocks lifted to 2.154 billion bushels with yield trimmed to 186.0 bpa, soybeans tightening modestly, and wheat loosening more than expected.

The bearish wheat and corn balance sheets reduce price support, while soybeans get mild support that depends on confirmed Chinese buying.
