Data not judgement required for Nordic banks' Basel approach
Nordic banks want to use the Basel framework’s advanced approach to credit risk capital, but local regulators are insistent that data – rather than judgement – has to be the basis for the calculations. Banks don’t have enough instances of default in…

A multi-state Vasicek model for correlated default rate and loss severity
Correlation between default and recovery has an important bearing on credit risk capital. Here, Rahul Sen shows that the effect can be modelled efficiently by allowing multiple loss states in the Vasicek framework. Heavy-tailed distributions result for…
A multi-state Vasicek model for correlated default rate and loss severity
Correlation between default and recovery has a major bearing on credit risk capital. Rahul Sen shows the effect can be modelled efficiently by allowing multiple loss states in the Vasicek framework. Heavy-tailed distributions result for arbitrary loss…

Uncovering PD/LGD liaisons
Francisco Sanchez, Roland Ordovas, Elena Martinez and Manuel Vega consider the presence of correlation between default and recovery through the familiar variance of loss formula. Business cycle dependence permits a neat decomposition of the variance…
Going downturn
There is much debate regarding the definition of 'downturn' loss given default (LGD). In this article, Michael Barco offers an analytic approach for calculating downturn LGD so that credit risk capital is not underestimated or overestimated

Modelling CDO tranches with dependent loss given default
Guido Giese presents an analytic methodology for pricing collateralised debt obligations tranches including stochastic and dependent loss given default

Default and recovery correlations - a dynamic econometric approach
Integrating coherences between defaults and loss given default (LGD) is postulated by Basel II. If there is a positive correlation between the two, separate models for each lead to biased estimates for the LGD parameters, and the economic loss is…

Modelling and estimating dependent loss given default
Martin Hillebrand proposes a portfolio credit risk model with dependent loss given default (LGD), offering a reasonable economic interpretation that is easily applicable to real data. He builds a precise mathematical framework, and stresses some…
A saddle for complex credit portfolio models
Guido Giese applies the saddle-point approximation to analyse tail losses for very general credit portfolios, including correlated defaults, stochastic recovery rates, and dependency between default probabilities and recovery rates. The numerical…
Web-based monitoring system targets requirements for mortgage lenders
Basel II has left many mortgage providers with additional requirements for enhanced and improved tracking of credit rating structures, presenting a challenge to some traditional monitoring systems.
Basel Committee clarifies 'Downturn LGDs'
The Basel Committee has issued clarification relating to the quantification of loss-given-default (LGD) parameters used for Pillar 1 capital calculations, as requested by banks and national bank supervisors. The LGD Working Group, established in…
From Basel II to Basel III
Financial institutions face major challenges in modelling credit portfolio risk, particularly in the field of CDOs. Walter Schulte-Herbrüggen and Gernot Becker argue that the main challenge will be in model testing, due to the increasingly customised…
