What is Portfolio Margin?

Unlike regular margin, which calculates margin on the contract level, BIT portfolio margin (“PM”）evaluates the risk on the portfolio level by computing the most likely loss could occur to a portfolio under a series of hypothetical market scenarios. After the PM account is enabled, the client will be able to find the risk parameters published on the ‘Portfolio Margin’ page of BIT and monitor the client's overall margin level.

Compare to the regular margin model, PM model tends to reward hedgers by offering a greater capital efficiency to their well-maintained low-risk portfolios. For speculators who have directional portfolios, however, a lower margin is not always guaranteed with the PM enabled. Please be noted that one’s account will not always be better off with PM enabled. Examples: a long option account might be more likely to trigger liquidation under the certain market conditions with PM enabled compare to the regular margin mode.

To be qualified for a PM account, below are the minimum criterias to be met:

​Sample of Option Trading under Portfolio Margin:
​
The client uses the Put Spread strategy to buy 250 ETH (strike price=2000) put options expiring on 11/24 and sell 250 ETH (strike price=1950) the put options expiring on 11/24.
At this time, due to the Put Spread form, the risk is relatively limited. The margin calculated in BIT's PM mode and well-known exchanges' PM mode is as follows:
​
​Buy Put Spread strategy, expiry date 11/24 situation (Buy 250 ETH Put @ 2000, Sell 250 ETH Put @ 1950)

*Margin unit USDT

At this time, the customer wants to sell 50 ETH of the put options he already holds (strike price = 2000). Since he sells the put options he holds, the overall portfolio risk is caused by the put options he has sold (strike price = 1950). Overall risk rises
At this time, the margin under PM will become the following situation due to the increase in risk
​
​Sell ​​part of the purchased put, expiration date 11/24 (buy 200 ETH Put @ 2000, sell 250 ETH Put @ 1950)

*Margin unit USDT
​
​Note: The margin under PM may be greater than the premium of the option
