同学你好,
在双边净额结算(bilateral netting)中,两两之间Exposure相互抵消。具体计算如下:
Firm 1:
- Exposure给Firm 2: AUD 90 million
- Exposure给Firm 3: AUD 12 million
- 从Firm 2: AUD 60 million
- 从Firm 3: AUD 70 million
净Exposure计算= (90 + 12) - (60 + 70) = 102 - 130 = -28
因此,Firm 1的净Exposure为AUD 0 million(负值表示没有Exposure)。
Firm 2:
- Exposure给Firm 1: AUD 60 million
- Exposure给Firm 3: AUD 57 million
- 从Firm 1: AUD 90 million
净Exposure计算= (60 + 57) - 90 = 117 - 90 = 27
因此,Firm 2的净Exposure为AUD 27 million。
Firm 3:
- Exposure给Firm 1: AUD 70 million
- 从Firm 2: AUD 57 million
- 从Firm 1: AUD 12 million
净Exposure计算= 70 - (12 + 57) = 70 - 69 = 1
因此,Firm 3的净Exposure为AUD 1 million。

在中央清算(central clearing)中,CCP(中央对手方)承担所有的Exposure,计算方法如下:
1. CCP对Firm 1的Exposure:
- Firm 1的Exposure = 90 + 12 = AUD 102 million
- CCP的Exposure = 60 + 70 = AUD 130 million
- 净Exposure = 130 - 102 = 28 million
2. CCP对Firm 2的Exposure:
- Firm 2的Exposure = 60 + 57 = AUD 117 million
- CCP的Exposure = 90 million
- 净Exposure = 90 - 117 = -27 million
因此,CCP的净Exposure为AUD 0 million(负值表示没有Exposure)
3. CCP对Firm 3的Exposure:
- Firm 3的Exposure = 70 million
- CCP的Exposure = 12 + 57 = 69 million
- 净Exposure = 69 - 70 = -1 million
因此,CCP的净Exposure为AUD 0 million(负值表示没有Exposure)
综上,CCP的净Exposure是所有净Exposure的总和,在这个例子中为AUD 28 million。
希望能解答你的疑惑,加油!
