Chicago | Reuters—Chicago soybeans fell on Monday after hitting two-month highs on Friday, as industry players lost confidence that Chinese buyers would purchase U.S. soybeans, while dealers assessed exemptions granted to U.S. crude oil refiners for use of soy-based biofuels.

Corn firmed after a crop tour forecast the U.S. harvest below estimates from the U.S. Department of Agriculture. Wheat rose on spillover support from corn futures and hopes of U.S. export sales with Black Sea prices robust.

Chicago Board of Trade most-active soybeans Sv1 settled 10-3/4 cents lower to $10.47-3/4 per bushel.
