12. How is Derivatives risk offset carried out in the Portfolio margin account?

Portfolio margin account conducts stress tests under various risk scenarios for derivatives: futures, perpetual swaps and options. Account margin is then set at maximum loss value. If the risks of different positions can compensate each other, margin is then deducted accordingly. Risk scenarios don’t include spot and margin positions. If position values are too low, margin under Unified account can also be lower.

The following examples show typical position margin cases under portfolio margin account. Actual margin may be different due to market volatility:

(1) Futures calendar spread arbitrage: BTCUSD quarterly futures +480,000 contracts. BTCUSD weekly futures +480,000 contracts. Unified account maintenance margin = 23,000,000 USD. Portfolio margin account maintenance margin = 4,000,000 USD.

(2) Unilateral long futures positions: BTCUSDT quarterly futures +1,000 contracts. Unified account maintenance margin = 0.2 BTC. Portfolio margin account maintenance margin = 1.6 BTC.

(3) Unilateral short options positions: BTCUSD weekly options -10,000 contracts. Unified account maintenance margin = 4,600,000 USD. Portfolio margin account maintenance margin = 650,000 USD. (4) Intertemporal covered call portfolio of futures and options: Sell 678 contracts of BTCUSD bi-weekly call options at 70,000 USD and buy 13,000 contracts of BTCUSD quarterly futures. Unified account maintenance margin = 560,000 USD. Portfolio margin account maintenance margin = 200,000 USD.
