Counterparty Risk and CVA › Summary

This chapter covered counterparty credit risk and Credit Valuation Adjustment, essential concepts for anyone working with OTC derivatives.

The key takeaways are:

• Counterparty risk has option-like character: You face losses only when derivatives have positive value at default, creating asymmetric exposure that must be modeled through expected positive exposure
• CVA integrates exposure, default probability, and loss given default: The fundamental formula combines simulated exposure profiles with credit information from CDS markets to produce a fair price for counterparty risk
• Exposure profiles differ by product: Interest rate swaps show hump-shaped profiles, while cross-currency swaps concentrate exposure near maturity; these patterns inform risk management
• Netting and collateral dramatically reduce exposure: Legal documentation through ISDA Master Agreements and CSAs can reduce CVA by 70-90%, explaining the post-crisis push for margining
• CVA desks centralize counterparty risk management: Banks hedge CVA using CDS and manage the P&L volatility from credit spread movements
• The XVA family extends beyond credit: DVA, FVA, KVA, and MVA capture other costs and benefits that affect derivative valuations

CVA calculation remains one of the most computationally intensive areas of quantitative finance, requiring sophisticated simulation techniques and careful modeling of dependencies. As we'll see in the next chapter on liquidity risk, the crisis-era reforms that CVA helped motivate continue to reshape how financial institutions measure and manage risk.
