First of all, the weather has an important influence on the growth and yield of corn. Suitable weather conditions can promote the healthy growth of maize and increase its yield. However, unfavorable weather conditions may lead to slow growth and decreased production.

Secondly, according to the latest report of USDA, it is estimated that the global corn output will increase by more than 6% in 2023/24 compared with last year, and the ending inventory will also increase accordingly. The corn production in the United States is expected to be 388 million tons, a substantial increase over last year. Domestically, the corn harvest area and total output have also increased.

Finally, policy adjustment is also one of the important factors affecting the corn market. The government's policy support for corn planting may be adjusted, which will have an impact on farmers' enthusiasm for planting and corn supply. If the government increases its support for corn planting, it may increase farmers' enthusiasm for planting, thus increasing the supply of corn. On the contrary, if the government reduces its support for corn planting, it may lead to the decrease of farmers' enthusiasm for planting, thus reducing the supply of corn.
