Treasury can make money by selling soybean oil, but the degree of making money is related to market supply and demand and price fluctuation. The national treasury refers to the national reserve of soybean oil, and its sale can affect the market supply and thus the price. If the market demand is large and the price is high, the national treasury can obtain higher profits by selling soybean oil. But if the market demand is small and the price is low, the possibility of making money is relatively small. In addition, the government also needs to consider the factors of stabilizing market prices and supply, so the operation of the national treasury is also affected by policy regulation. In short, the national treasury has the potential to make money by selling soybean oil, but the specific situation needs to be judged according to market trends and policies.
