Counterparty credit risk (CCR) is the risk that the other party in a financial transaction will default before the final settlement of the transaction's cash flows. Unlike traditional credit risk in lending, CCR involves bilateral risk — both parties face potential losses. Understanding CVA and DVA is critical for FRM Part 2 success.
What Is Counterparty Credit Risk?
In OTC derivatives, both parties are exposed to each other's default risk. If you enter an interest rate swap and your counterparty defaults when the swap has a positive mark-to-market value to you, you lose that value. This is fundamentally different from a bond, where only the lender bears credit risk.
Key Exposure Metrics
| Metric | Definition |
|---|---|
| Current Exposure (CE) | The loss if the counterparty defaults today (max of MTM value and zero) |
| Potential Future Exposure (PFE) | The maximum expected exposure at a future date at a specified confidence level |
| Expected Exposure (EE) | The average exposure at a future date |
| Expected Positive Exposure (EPE) | The time-weighted average of expected exposures over a period |
| Exposure at Default (EAD) | The estimated exposure when default actually occurs |
Credit Valuation Adjustment (CVA)
CVA is the market price of counterparty credit risk. It represents the difference between the risk-free portfolio value and the portfolio value accounting for the counterparty's possibility of default.
CVA Formula (Simplified)
$$CVA \approx \sum_{i=1}^{n} EE(t_i) \times PD(t_{i-1}, t_i) \times LGD$$
Where:
- EE(tᵢ) = Expected Exposure at time tᵢ
- PD = Probability of Default during the interval
- LGD = Loss Given Default (1 − Recovery Rate)
CVA is essentially the expected loss from counterparty default over the life of the derivative, discounted to present value. Banks must hold capital against CVA risk under Basel III regulations.
Debit Valuation Adjustment (DVA)
DVA is the mirror image of CVA — it reflects the value to you of your own potential default. If your creditworthiness deteriorates, your liabilities to counterparties decrease in market value, which is a "gain" from your perspective.
DVA Formula (Simplified)
$$DVA \approx \sum_{i=1}^{n} NEE(t_i) \times PD_{own}(t_{i-1}, t_i) \times LGD_{own}$$
Where NEE is the Negative Expected Exposure (exposure from the counterparty's perspective).
The DVA Controversy
DVA is controversial because:
- A bank's credit quality worsening creates an accounting gain
- Realizing DVA gains by monetizing your own default risk is impractical
- Under Basel III, DVA gains are excluded from regulatory capital calculations
- IFRS 13 and ASC 820 require DVA recognition in fair value measurements
Bilateral CVA (BCVA)
When both CVA and DVA are considered together, we get Bilateral CVA:
$$BCVA = CVA - DVA$$
This reflects the net credit risk from both counterparties' perspectives.
Netting and Collateral
Two critical risk mitigants for counterparty credit risk:
Netting Agreements
Close-out netting allows parties to offset positive and negative exposures on default, significantly reducing exposure. Under an ISDA Master Agreement, if you have 10 trades with a counterparty, the net exposure replaces the gross exposure.
Collateral (CSA)
Under a Credit Support Annex (CSA), parties post collateral (typically cash or government bonds) to cover mark-to-market exposures. Collateral reduces exposure but introduces margin period of risk — the time between the last collateral exchange and closeout of positions.
Wrong-Way Risk and Right-Way Risk
- Wrong-Way Risk (WWR): Exposure increases when the counterparty's credit quality deteriorates. Example: buying a put option from a bank whose credit is correlated with the underlying asset declining.
- Right-Way Risk: Exposure decreases when the counterparty's credit quality deteriorates. This is more favorable but less common.
Central Counterparties (CCPs)
Post-2008 regulatory reforms require many standardized OTC derivatives to be cleared through CCPs. A CCP becomes the counterparty to both sides of a trade, mutualizing credit risk. Key CCP risk concepts include:
- Default fund contributions
- Initial margin and variation margin
- Loss waterfall
