Grain trade refers to the buying and selling of cereal crops, such as wheat, corn, and rice, which are essential for food production worldwide. This trade occurs both domestically and internationally, allowing countries to meet their food needs and manage surplus production. The grain market is influenced by various factors, including climate conditions, government policies, and global demand. Major grain-exporting countries, like the United States and Brazil, play a significant role in stabilizing prices and ensuring food security for importing nations.
