How does counterparty credit risk specifically differ from issuer default risk?

Q: How does counterparty credit risk specifically differ from issuer default risk?

Consider two exposures to hypothetical Briardale Holdings:\n\n**Exposure A — Bond**: $50M 5-year senior unsecured note, BBB rated. If Briardale defaults, you lose (1 - RR) × $50M = 0.6 × 50 = $30M assuming 40% recovery. The loss is known the day you buy.\n\n**Exposure B — Interest rate swap**: Receive fixed 3.5%, pay SOFR on $200M notional for 5Y. MtM depends on rates. If rates rise, the receive-fixed side loses value; if rates fall, it gains. You're only exposed when MtM is positive to you.\n\nFive key differences:\n\n1. **Exposure magnitude** — bond exposure is the face value; swap exposure is MtM, which is usually a small fraction of notional.\n\n2. **Direction uncertainty** — bond is always your asset; swap can be your asset or liability.\n\n3. **Time variation** — bond exposure declines as coupons are paid; swap exposure typically rises toward the middle of its life then declines.\n\n4. **Mitigation techniques** — bonds have covenants and collateral rarely; swaps have netting (ISDA master), collateral (CSA with daily variation margin), central clearing, SA-CCR capital, and initial margin.\n\n5. **Regulatory capital** — bonds use standardized risk weights or IRB PD·LGD·EAD; swaps use SA-CCR (or IMM) for EAD plus CVA capital charge.\n\nFor FRM, remember the formula: CCR EAD ≈ α × EEPE where α = 1.4 (Basel multiplier) and EEPE = time-weighted Effective EPE. The comparison to a bond is: bond EAD = face value; swap EAD = a dynamic risk measure.

Consider two exposures to hypothetical Briardale Holdings:

**Exposure A — Bond**: $50M 5-year senior unsecured note, BBB rated. If Briardale defaults, you lose (1 - RR) × $50M = 0.6 × 50 = $30M assuming 40% recovery. The loss is known the day you buy.

**Exposure B — Interest rate swap**: Receive fixed 3.5%, pay SOFR on $200M notional for 5Y. MtM depends on rates. If rates rise, the receive-fixed side loses value; if rates fall, it gains. You're only exposed when MtM is positive to you.

Five key differences:

1. **Exposure magnitude** — bond exposure is the face value; swap exposure is MtM, which is usually a small fraction of notional.

2. **Direction uncertainty** — bond is always your asset; swap can be your asset or liability.

3. **Time variation** — bond exposure declines as coupons are paid; swap exposure typically rises toward the middle of its life then declines.

4. **Mitigation techniques** — bonds have covenants and collateral rarely; swaps have netting (ISDA master), collateral (CSA with daily variation margin), central clearing, SA-CCR capital, and initial margin.

5. **Regulatory capital** — bonds use standardized risk weights or IRB PD·LGD·EAD; swaps use SA-CCR (or IMM) for EAD plus CVA capital charge.

For FRM, remember the formula: CCR EAD ≈ α × EEPE where α = 1.4 (Basel multiplier) and EEPE = time-weighted Effective EPE. The comparison to a bond is: bond EAD = face value; swap EAD = a dynamic risk measure.
