Chicago soybeans closed higher at $13.94-3/4 a bushel, reaching their highest level since July on South American weather risks. Corn fell 7-1/4 cents to $6.02-1/4 and CBOT wheat fell 9-1/4 cents to $7.60-3/4.
Dryness in Argentina and southern Brazil threatened crops, while excess rain in northern Brazil slowed harvest.
Yield-loss risks in major exporting countries support soybean and corn prices. Harvest delays from wet weather in northern Brazil may also tighten near-term export availability.
