- Counterparty risk definition: Counterparty risk is the risk that a counterparty to a financial transaction will default or fail to perform its contractual obligations, resulting in financial loss. It arises in derivatives, securities lending, repo agreements, and bilateral OTC trades.
- Types of counterparty risk: The main types include pre-settlement risk (default before final settlement), settlement risk (failure to deliver on settlement date), and replacement cost risk (cost to replace a defaulted position at current market prices). Each type requires distinct measurement and mitigation approaches.
- Credit risk vs. counterparty risk: While credit risk generally refers to the risk of loss from a borrower's failure to repay, counterparty risk specifically applies to bilateral contracts where the exposure is contingent on future market movements. This contingent nature makes it more complex to quantify.
- Pre-settlement risk: This occurs when a counterparty defaults before the final cash flows are exchanged. The non-defaulting party must replace the contract at current market prices, incurring a loss if the replacement cost is unfavorable. It is the most common form of counterparty risk.
- Settlement risk: Also known as Herstatt risk, this arises when one party delivers its side of the transaction but does not receive the corresponding payment. It is particularly acute in cross-currency transactions where time zone differences delay final settlement.
- Replacement cost risk: After a counterparty defaults, the surviving party must enter into a new contract to replicate the original economic terms. The cost depends on the current market value of the position and the creditworthiness of the new counterparty.
- Wrong-way risk: This occurs when exposure to a counterparty is positively correlated with its probability of default. For example, a derivatives position that increases in value as the counterparty's credit deteriorates amplifies potential losses and requires specialized modeling.
- Right-way risk: The opposite of wrong-way risk, where exposure decreases as the counterparty's credit quality declines. This can mitigate losses but must still be monitored as correlations may shift during stress periods.
- Contingent exposure: Unlike a standard loan, the exposure amount in a derivative contract can change over time based on underlying market variables. This dynamic nature means that risk managers must forecast potential future exposure under various market scenarios.
Financial Formula
Replacement Cost (RC)
RC = max(V, 0)
RC = max(V, 0)
Where:
- V: The current market value of the derivative contract from the perspective of the non-defaulting party
- RC: The cost to replace the contract if the counterparty defaults; zero if the contract has negative value to the holder
Regulatory Requirement
Regulation: Basel III
Basel III requires banks to calculate counterparty credit risk capital using the Standardized Approach for Counterparty Credit Risk (SA-CCR), which incorporates replacement cost and potential future exposure. The framework mandates that banks hold capital against both current exposure and a multiplier applied to the notional amount of transactions.
Quick Revision
- Counterparty risk is the risk of default by a transaction counterparty, leading to financial loss.
- Key types include pre-settlement, settlement, and replacement cost risk.
- Wrong-way risk is a significant concern where exposure and default probability are positively correlated.
- Replacement cost is calculated as the positive market value of the contract and is a critical component of exposure measurement.
