Managing Counterparty Credit Risk. Any firm participating in the OTC Derivatives market is exposed to the counterparty credit risk. Among them a common adopted measure is the Max Peak Exposure which stands for the maximum amount of loss that would occur if the counterparty were to default at any point in the future, for a given statistical confidence level. In that situation if the company suffers cash flow difficulties, the value of stock will drop as the probability of default increases. Part I: Comments 1. This mathematical expression and specifically the conditional expectation highlight the fact that there exists a correlation between the Bank exposure and the credit quality of the counterparty materialized by its expected default frequency.

Part IV: Managing Counterparty Credit Risk. The market volatility experienced during the financial crisis has driven many firms to review their methods of accounting for counterparty credit risk.
The traditional approach of controlling counterparty credit risk has been to set limits against future exposures and verify potential trades against these limits. Credit Value Adjustment CVA is new risk measure that offers an opportunity for banks to move beyond the system control of limits and to price dynamically counterparty credit risk of new trades.
Many banks already measure CVA in their accounting statements, but the financial crisis has led pioneering banks to invest in systems that more accurately assess CVA, and integrate CVA into pre-deal pricing and structuring.
Towards active management of counterparty credit risk with CVA. Any firm participating in the OTC Derivatives market is exposed to the counterparty credit risk.
This risk has been defined as the risk that occurs when counterparty defaults, implying the non-payments of the future cash flows that were agreed on the derivatives contracts. Then modeling the credit future exposures is a fundamental part of the risk management and it introduces changes on the day to day pricing and hedging on transactions within this market.
Basel II Accords introduces many statistics on the law of distribution of the Future to Market in order to estimate the potential positive future exposures:. Among them a common adopted measure is the Max Peak Exposure which stands for the maximum amount of loss that would occur if the counterparty were to default at any point in the future, for a given statistical confidence level.
Say it in another words, it is the greatest future exposure over all future paths of the relevant market risk factors between now and the future maturity date of the contracts.
Another kind of risk that was under estimate or neglected is that the value of the derivative contract can be highly and adversely correlated to the creditworthiness of the counterparty.
This type of risk is often referred to the Wrong Way Risk. Specific WWR arise when for instance a company chooses to use its own shares as collateral for position taking. In that situation if the company suffers cash flow difficulties, the value of stock will drop as the probability of default increases. This leads to a depreciation of the collateral value held to cover delivery of contracts the firm has open. General form of Wrong Way Risk arises when the credit quality of the counterparty may for non-specific reasons may be correlated with other macroeconomic factors that may also impact the exposure of open derivatives transactions.
General Wrong Way Risk is linked to the economic conjectural factors that are both hard to detect on a Bank trading book and also hard to measure. Assume that an investor A protection buyer buys a CDS from its counterparty, a bank B protection seller on a reference entity E that potentially can defaulted on. This situation is typical of what we have called specific Wrong Way Risk. The financial market turmoil that started on has clearly highlighted this underlying risk on OTC transactions.
Other institutions take into accounts this underlying risk but did not actively price or manage it. Today it becomes obvious that the counterparty credit risk should also be taken into account when reporting the fair value of any derivative position. The Credit Value Adjustment is by definition the difference between the risk-free portfolio and the true portfolio value that takes into account the possibility if a counterparty's default.
In other words, CVA represents the market value of the counterparty credit risk. Risk neutral probability: Time when the default will occur We also make the assumption that the Recovery Rate at default is a known constant and we then have the general expression of the CVA:.
This mathematical expression and specifically the conditional expectation highlight the fact that there exists a correlation between the Bank exposure and the credit quality of the counterparty materialized by its expected default frequency.
In other words this measure introduces the joint distribution of market factors and the credit factors that drives the potential default of the counterparty. CVA measure changes environment for pricing and managing counterparty risk and most users derivatives have already CVA groups dedicated to controlling counterparty credit risk for their business lines.
It seems natural to centralize the management of CVA since a typical counterparty can be linked with numerous trading desks. This way the Trading Desk is free of:.
Running in parallel of the Trading Desk, the CVA Desk has in charge to express CVA as a scalar representing the spread between a risk-free and credit risky valuation of a trade or a portfolio.
At portfolio level CVA is unfortunately not an additive measure and this implies that the Global CVA at global portfolio level cannot be computed as the sum of the individual CVA trades. This is due to the netting and collateral agreements that prevail on some OTC transactions and also due to the nature of the credit exposure out the money Mark to Market have no exposure. They improve the competitive advantage within transaction, and help to realize when it is best to run away from some risky full counterparties and when it is interesting to increase the level of business with some reliable counterparties.
