A Grain Exchange is a marketplace where various types of grains, such as wheat, corn, and rice, are bought and sold. These exchanges facilitate trading by providing a platform for farmers, traders, and investors to negotiate prices and contracts. The goal is to ensure fair pricing and efficient distribution of grain products. Grain exchanges often operate under specific rules and regulations to maintain transparency and fairness in trading. They may also provide services like price discovery, risk management, and market information. Notable examples include the Chicago Board of Trade and the Minneapolis Grain Exchange.
