A bottom-up model with top-down dynamics
Yadong Li proposes a flexible, tractable and arbitrage-free bottom-up dynamic correlation modelling framework with a consistent stochastic recovery specification for multi-name credit derivatives. In this framework, the model’s spread dynamics can be…
Sponsored statement: The problems with generally used interpolation spaces
In a world increasingly focused on effective enterprise-level risk management, there are notable discrepancies in volatility management techniques. Murex proposes a cross-asset interpolation space with potentially significant risk management impacts

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…
Estimating credit contagion in a standard factor model
State-of-the-art credit risk portfolio models and the new Basel capital Accord consider only symmetric dependencies between borrowers in a portfolio, such as correlations. Recently, asymmetric dependencies have been introduced by Davis & Lo (2001), among…
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…
RAPM popular, but doubts remain over reliability
Risk-adjusted performance measurement (RAPM) techniques are spreading rapidly across the risk management industry, but many still doubt how reliable the results are, according to an industry survey.
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.
PD estimates for Basel II
One of the main issues banks will have to face to comply with the new Basel II internal ratings-based approach is to prove that the long-run average probabilities of default they assign to their clients, which will be used as the basis for regulatory…
S&P warns banks against reducing capital too soon in anticipation of Basel II
Standard and Poor's will review, and possibly downgrade, issuers that will be found to have reduced their capital levels in anticipation of the effect of the new Basel Accord, also known as Basel II, according to Paris-based Scott Bugie, the rating firm…
