Counterparty Risk Stress Testing Calculator

Understanding Counterparty Risk and Economic Capital

Counterparty credit risk represents the risk that a counterparty defaults before fulfilling financial obligations. Financial institutions deploy robust stress testing architectures to measure severe market disruptions, assessing potential spikes in Exposure at Default (EAD) combined with deteriorating counterparty credit profiles.

Economic capital acts as an internal buffer calculated via advanced statistical frameworks like the Vasicek Single Risk Factor model. It cushions unexpected losses exceeding institutional expected loss baselines at elite confidence thresholds such as 99.9 percent.

Formulas Used

• Stressed EAD: $EAD_{stressed} = Notional \times EAD_{ratio} \times (1 + Macro + FX) \times Netting \times (1 - Haircut)$
• Expected Loss (EL): $EL = EAD_{stressed} \times PD_{stressed} \times LGD_{stressed} \times Concentration$
• Economic Capital (EC): Derived using asymptotic single risk factor model adjustments across chosen confidence percentiles.

How to Use This Calculator

1. Input core portfolio figures like total notional amount, default probabilities, and recovery loss parameters.
2. Adjust macroeconomic shocks, FX volatility spikes, netting efficiencies, and collateral haircuts.
3. Select your preferred risk confidence level and time horizon, then click calculate to view analytics.

Frequently Asked Questions

What is the primary objective of stress testing? Stress testing identifies hidden vulnerabilities by simulating severe historical or hypothetical financial crises.

How does economic capital differ from regulatory capital? Economic capital is internally modeled to reflect exact risk profiles, whereas regulatory capital follows rigid standardized formulas.
