Prices for key crops on the Chicago Stock Exchange surged, with wheat, corn, and soybeans all seeing increases following a period of uncertainty ahead of President Trump's return to the White House. The absence of immediate customs duty increases has led to a bullish market response. The potential for a trade agreement between the US and China, which could result in increased American agricultural purchases, has further bolstered optimism. However, concerns over Brazilian corn exports and the impact of cold weather on the winter wheat belt add some uncertainty to the outlook.
