With the economic downturn and Sino-US trade friction, gold has become a variety of investment for many people. With the price of gold rising step by step, many people want to know how much gold futures are worth. The margin ratio of gold futures is set by the futures exchange for futures companies, which is currently 9%. When the futures company provides it to customers, it is impossible to give 9% as much. Generally, it needs to be added. Now the futures company offers 1 1%. How much can gold futures buy? Generally, the margin ratio of primary futures gold is about 10%. If one gram of 350 yuan is1000g, the margin ratio is 10%. In this way, you need 350 yuan * 1 hand *1000g *10% = 35,000 yuan, but you only need 35,000 yuan, and you need risk money, because once you have a loss margin, you will be forced to close your position, so you need 50,000 yuan. However, the margin ratio is not fixed and will change in two situations: 1 According to the risk rules of the previous issue, when the contract enters the tenth trading day of the second month before the delivery month, the standard given by the exchange to futures companies will be raised to 10%, and the customer margin will be raised to14% accordingly; From the first trading day of 1 month before the delivery month, it is 15% and19% respectively; From the 10th trading day before the delivery month 1 month, 20% and 24% respectively; From the first trading day of the delivery month, 30% and 34% respectively; From two trading days before the last trading day, it is 40% and 44% respectively. 2 When the contract closes for 5 minutes on the last day, the margin ratio will be raised to 8% on the second day (not mentioned at present, because it is now 9%) and to 10% on the third day. Futures companies are also raised accordingly. Therefore, it is more appropriate to buy gold futures and invest 50 thousand yuan. If the price of gold is one gram of 350 yuan and the primary price is 350,000 yuan, the required deposit is 35,000 yuan. 50,000 yuan is more appropriate, because the proportion of the deposit will change, and it is also to prevent it from being flattened.
