You calculate 4080 yuan per ton according to the current rebar futures price, and 40800 yuan according to 10 ton. Take this money to open an account with a futures company and buy a rebar futures contract for a long time. Be sure to open only one hand. Then tell your broker to remind you to change positions before the contract expires. Two years later, you still hold a 10 ton rebar contract, and then you can take out the money to buy steel in the market.

Of course, because the transaction cost may be different from the futures and spot prices, you may be able to buy a little more than 10 tons of steel or a little less than 10 tons of steel after the money is taken out.

But I don't agree to use this method. It's too troublesome and risky. China's real estate is now too high to be cold, and there is a serious overcapacity of steel bars. Those steel mills are more anxious than you, and have been pushing down shipments. It doesn't cost too much to buy five tons of steel. It's better to put the money in the bank, buy it whenever you want, and just find a warehouse to save it.
