Counterparty credit risk pricing and measurement of swaption portfolios
This paper introduces a technique for pricing and risk measurement of portfolios containing swaption contracts in the presence of counterparty credit risk, under general market model and volatility assumptions.
A credit value adjustment scheme for bank loan portfolios
In this study the authors develop an analytical scheme that integrates a large spectrum of typical bank loans and credits, accommodates common bank loan portfolio chronological interdependencies and allows the necessary credit value adjustments (CVAs)…
Systematic risk factors redefined
Credit risk factor models tend to have a narrow focus on the Gaussian case, use copula functions that don’t work well with the martingale methods used in pricing, and can introduce arbitrage. Dariusz Gatarek and Juliusz Jablecki show how an increasing…

Cutting Edge introduction: systematic systematic factor models
Credit factor models tend to obscure the economics in favour of tractability – and this puts them at odds with rigorous arbitrage-free martingale pricing methods. To resolve this, quants are looking more closely at what a systematic risk factor actually…

Cutting Edge introduction: Wrong-way risk and the limits of correlation
Traditional models for wrong-way risk focus on the correlation between default and exposure – a blunt tool for a tail risk. Alternatives are thin on the ground, but a scenario-based approach may provide some fresh insight. Laurie Carver introduces this…

Model foundations of Basel III standardised CVA charge
The credit valuation adjustment (CVA) capital charge in Basel III comes in two flavours: advanced (simulations) and standardised (formula). In this article, Michael Pykhtin shows that the standardised CVA charge formula can be obtained by adding several…
