Soybean futures on the Chicago Mercantile Exchange rose on Thursday due to a technical recovery after hitting a four-year low, driven by expectations of a record crop in Brazil, decreased Chinese demand for U.S. soybeans, and uncertainties about U.S. biofuel policy. Despite these challenges, U.S. exporters have managed to sell soybeans to undisclosed destinations. The stronger U.S. dollar, making U.S. crops less competitive on the global market, and the anticipated harvest in South America continue to pose significant challenges. In other grain markets, Tunisia purchased wheat and durum in an international tender, and South Korea bought animal feed maize in a private deal, with the purchase likely to come from the U.S., South America, or South Africa.
