Futures is a margin transaction, just like you pay a margin before buying a house. If the state increases the down payment ratio, you must pay more deposit when buying a house. Besides, the account you calculated is wrong. I'll recalculate it for you.

Soybean price is 3000/ ton, and 10% deposit 100 lot needs 300,000. When the margin ratio becomes 15%, the margin required for 100 lots is 450,000, or only 66 lots can be bought for 300,000 lots. The futures company will close 34 positions for you and control the margin ratio.

In order to control risks and prevent customers from crossing positions, futures companies should increase the margin ratio according to regulations. How to ensure the safety of futures companies? Either let customers lighten up their positions or customers pay more.
