If it is volatile, personally, palm oil is the most volatile of the three oils. The main reason is that the main producers of palm oil are Malaysians and Indonesians, while China is one of the big consumers, and its import dependence is high, so the analysis may be relatively simple. As for soybean oil and rapeseed oil, raw materials are also relatively dependent on imports. The raw material of soybean oil is soybean, the import of soybean depends on America, and the raw material of rapeseed oil depends on Canada. Rapeseed oil and rapeseed meal are sometimes affected by the news of the Meng Wanzhou incident because of the tense relationship between China and Canada. There is also the consideration of soybean meal and rapeseed meal, and sometimes the question of profit. Sometimes there is a strong demand for soybean oil and rapeseed oil, but the poor sales of soybean meal or rapeseed meal in oil plants will cause the problem of inventory expansion.
