We analyzed the effects of Brazil and Argentina's currency devaluation on the U.S. soybean import demand in major importing countries. Results indicate that nominal exchange rates between the United States and importers affect the U.S. soybean export market. Additionally, we found evidence that currency depreciations have favored soybean exports from Argentina and Brazil at the cost of reduced exports from the United States. Increased world soybean demand has promoted export sales from major producers, affecting export prices. However, adoption of GM soybeans in the United States has been a determinant in decreased U.S. soybean exports.
