COUNTERPARTY RISK FOR CREDIT DEFAULT SWAPS:: IMPACT OF SPREAD VOLATILITY AND DEFAULT CORRELATION
contingent credit default swaps copula functions Counterparty risk Credit Default Swaps
2011/8/30
We consider counterparty risk for Credit Default Swaps (CDS) in presence of correlation between default of the counterparty and default of the CDS reference credit. Our approach is innovative in that,...
Correlation of financial markets in times of crisis

Using the eigenvalues and eigenvectors of correlations matrices of some of the main financial market indices in the world, we show that high volatility of markets is directly linked with strong correl...
The fine structure of spectral properties for random correlation matrices: an application to financial markets

We study some properties of eigenvalue spectra of financial correlation matrices. In particular, we investigate the nature of the large eigenvalue bulks which are observed empirically, and which have ...

Marking Systemic Portfolio Risk the Correlation Skew of Equity Baskets
2011/1/4
The downside risk of a portfolio of (equity)assets is generally substantially higher than the downside risk of its components. In particular in times of crises when assets tend to have high correlatio...

2010/10/22
In this paper we propose a copula contagion mixture model for correlated default times. The model includes the well known factor, copula, and contagion models as its special cases. The key advantage ...

This paper describes a flexible and tractable bottom-up dynamic correlation modelling framework with a consistent stochastic recovery specification. The stochastic recovery specification only models ...
In the recent years, banks have sold structured products such as worst-of options, Everest and Himalayas, resulting in a short correlation exposure. They have hence become interested in offsetting par...
