Which one is not the price influencing factor of soybean futures? Monetary policy is not the price influencing factor of soybean futures. Soybean futures prices will not be directly affected by monetary policy. Monetary policy involves money supply, interest rate, exchange rate and other factors, which mainly affects the value of money and the liquidity of the market, but does not directly affect the supply-demand relationship or production cost of soybeans, so it will not become an important factor in the fluctuation of soybean futures prices. Soybean futures refer to derivative contracts with soybeans as the subject matter. Futures contracts allow buyers and sellers to deliver a certain amount of soybeans at an agreed price on a specific date in the future.
