In this study we develop and demonstrate a powerful and flexible forward-looking portfoliosimulation methodology for assessing the correlated impacts of market risk, and privatesector, sovereign and inter-bank default risk on both individual banks (i.e. 28 of the largestBrazilian banks) and...

This paper studies the relative pricing of euro area sovereign CDS and the underlying government bonds. Our sample comprises weekly CDS and bond spreads of ten euro area countries for the period from January 2006 to June 2010. We first compare the determinants of CDS spreads and bond spreads and...

Estimating asset correlations is difficult in practice since there is little available data and many parameters have to be found. Paul Demey, Jean-Frédéric Jouanin, Céline Roget and Thierry Roncalli present a tractable version of the multi-factor Merton model in which firms are sorted into...

We give a complete algorithm and source code for constructing what we refer to as heterotic risk models (for equities), which combine: i) granularity of an industry classification; ii) diagonality of the principal component factor covariance matrix for any sub-cluster of stocks; and iii)...

This study measures the effects of specific credit risk factors of companies that defaulted during the Asian currency and global credit crises. Using Taiwanese listed companies' data, the predictability of specific credit risk factors were discrepancies during these 2 crises. First, I captured...

The Basel Committee has made it a goal to create a regulatory framework that is simple, comparable and risk sensitive for the measurement of insolvency risk and the determination of capital adequacy. To this end, our contribution in this paper is to propose a novel dynamic geometrical...

The risks to global financial stability posed by recent defaults by government borrowers have, for the most part, been manageable. However, the dynamics underpinning the ad hoc arrangements for resolving sovereign defaults are changing. Public debt burdens in many advanced economies are set to...

This paper discusses the concept of leverage, its components and how to measure and monitor it. It proposes an innovative approach to assessing leverage based on flows using the concept of a marginal leverage ratio, which reveals the leverage related to new activities, as a valuable supplement...

We give a simple explicit algorithm for building multi-factor risk models. It dramatically reduces the number of or altogether eliminates the risk factors for which the factor covariance matrix needs to be computed. This is achieved via a nested "Russian-doll" embedding: the factor covariance...

Total notional principal outstanding for single-name credit default swaps (CDSs) based on corporate and sovereign reference entities grew significantly through June 2011, but, following the global credit crisis and Eurozone sovereign debt crisis, notional amounts on single-name CDSs outstanding...
