Chicago soybean futures were mixed, with the January contract gaining 5.5 cents to $11.9375 per bushel, as traders covered short positions ahead of the USDA monthly supply-and-demand report. A reported large Chinese soybean purchase and expectations that USDA would lower its U.S. production and ending-stock forecasts also supported prices; corn futures edged higher, though gains were limited.
Chinese buying adds demand support for U.S. soybeans, while anticipated tighter USDA balances could reinforce a firmer tone in both soybean and corn markets. The moves reported were modest and partly driven by position adjustment ahead of the report.
