1, domestic soybean oil futures and American soybean oil futures have a high correlation, mainly because soybean and soybean oil futures can be regarded as shadow varieties of soybean oil futures, but their trading objects are different. For example, palm oil belongs to soybean oil, while soybean oil belongs to soybean oil and vegetable oil.

2. In addition, American soybean oil futures are American soybeans, and soybeans are important soybean crude oil varieties in China. Because domestic soybeans and soybean oil are not directly produced soybeans, there is a great correlation between them.
