Argentina starts the season with a significant moisture deficit because La Nina is persisting for a third consecutive season. Crop condition ratings for soybeans and corn are poor, and forecasts call for dry, warm weather through mid-January.
Continued dryness threatens Argentine soybean and corn output, which are major exports of meal, oil and grain, so the risk supports prices for these commodities.
