Chicago soybeans dipped on Tuesday after hitting a seven-week high on Monday due to concerns over US yields and Brazilian weather. Wheat and corn prices also fell in early Asian trade. The soybean market had surged 2.7% on Monday amid worries about Brazilian crop weather and US yields. The USDA maintained its national soybean yield estimate at a record 53.2 bushels per acre, while dry weather in Brazil delayed planting. Commodity funds' significant net short positions in soybean and corn futures make these markets prone to short-covering. The USDA reported the US corn harvest at 14% complete, slightly below expectations but above the five-year average. European trade association Coceral reduced its estimate of the EU and Britain's grain crop. Global stock indexes rose on Monday after a significant interest rate cut by the Federal Reserve, while the euro weakened against the dollar due to poor euro zone business activity readings.
