Soybean prices on the Chicago Stock Exchange fell by over 1% due to negative impacts on soybean meal in Argentina and the falling dollar in Brazil. Recent rainfall in Argentina has reduced the index of soybean crops in fair or poor conditions from 50% to 30%, but harvest estimates vary from 49.6 to 45 million tons. The market is currently cautious, awaiting the USDA's new monthly supply and demand bulletin, which is expected to cut South American harvest figures. The market is also closely monitoring weather conditions and the volatility of the dollar against the real.
