Pig futures are futures that reflect the fluctuation of pork prices, and are a type of futures such as soybeans and corn. In China, live pigs are the most valuable agricultural and sideline products in China, with a market scale of nearly one trillion yuan. Therefore, the emergence of hog futures will play a positive role in improving the formation mechanism of hog price, enhancing the risk management ability of market participants and hindering the development of hog industry. Of course, pig futures can regulate the price of pork and restrain the abnormal operation of the price.
