US soyabean futures fell to a 1-1/2-week low on Monday on technical selling and on concerns about demand from China as the world's top soya importer remains locked in a tariff war with the United States. Wheat also fell after Russia, the world's top supplier, left its export forecast unchanged despite recent speculation that supplies are dwindling.
Corn drifted lower, following soya and wheat.
Grain markets languished as Chinese trade figures dampened demand sentiment and fuelled concerns across financial markets about an economic slowdown in China and beyond.
China's General Administration of Customs said December soya imports in December fell 40 percent from the same month a year earlier, the lowest for the month since December 2011.
Future Chinese demand for animal feed imports also remained a concern due to the spread of African swine fever, which has prompted culling of the hog herd and pressured Chinese soyameal prices.
Losses in grain futures were limited, however, by concerns about adverse growing weather for corn and soyabeans in South America, as well as continuing hopes of fresh Chinese purchases during a 90-day truce for negotiations. US officials expect China's top trade negotiator to visit Washington this month, signalling higher-level discussions are likely to follow last week's talks in Beijing.
Chicago Board of Trade March soyabeans fell 8-1/2 cents to $9.01-3/4 a bushel by 11:52 a.m. CST (1752 GMT) after breaching chart support at several key moving averages.
March corn was 1-1/4 cents lower at $3.77 a bushel. CBOT March wheat shed 5-1/2 cents to $5.14 a bushel, dropping below its 20- and 50-day moving averages. Easing concerns about harsh cold in the US Plains wheat belt weighed on prices as farm fields in a large portion of the region received several inches of snow over the weekend.
