Improving futures margin is the need of daily operation and management of futures trading, and will not affect the price of futures itself. Raising futures margin means that the market is controlling risks. If the exchange thinks that the risk of the futures contract is too high, it will increase the margin and reduce the leverage, thus reducing the risk of investors shorting.

Futures trading is margin trading, and the margin ratio is generally 5- 10% of the value of futures contracts. Generally, the higher the margin is on holidays or the closer to the futures delivery date, mainly to limit the risk of futures trading.
