Since the spot crude oil is a margin transaction, the minimum margin of the spot crude oil standard contract is 5%, which means that you made a transaction of 100% with 5% capital, and the capital was enlarged by 20 times.

Generally speaking, the leverage of margin financing and securities lending is an amplifier. The original 10000 yuan can be changed into10000 n through a certain lever (n is the lever). For example, the leverage of spot crude oil is 1: 20. Then, 10000 yuan will be enlarged to 200000 yuan.

Originally, you could only invest 10000 yuan, but now you can use it as 200000 yuan, which is equivalent to your capital being enlarged 20 times. Similarly, if you want to buy 1 ton spot crude oil, suppose you need 40,000 yuan, then you only need 200 yuan to buy the contract of 1 ton spot crude oil.
