CHICAGO, April 5 (Reuters) – Soybean futures on the Chicago Board of Trade were expected to open down 8 to 10 cents a bushel Tuesday, pressured by news China was raising benchmark deposit and lending rates in an attempt to cool inflation. Also weighing on prices is the advancing harvest of what is expected to be a record South American soybean crop, and talk that soy orders may be switched from the U.S. to South America. China’s central bank raised interest rates for the second time this year on Tuesday, bringing its one-year deposit rate to 3.25 percent and the equivalent lending rate to 6.31 percent, and stepping up efforts to cool inflation. Drier weather in Argentina over the next 7 days will boost crop harvest and also favor maturing crops. Drier conditions in Brazil also will help improve harvest progress. Brazil’s 2010/11 soybean crop, which is more than two-thirds harvested, is seen at a record 70.56 million tonnes, up from the March view of 69.8 million tonnes, grains analysts Celeres said on Monday.
