Unter die Kategorie der Marktrisiken einer bestimmten Finanzposition subsumieren wir allgemein alle Risiken, die aus der Veränderung des Marktpreises dieser Position über eine bestimmte Zeitperiode resultieren. Die Finanzposition kann dabei ein einzelner Finanztitel, eine Klasse von...

The goal of the paper is to present the intervention strategies used by central banks in order to influence the value of the domestic currency, transparency versus discretion when it comes to publishing data about FX intervention and the cost and effectiveness of intervention. It is rarely that...

We propose several connectedness measures built from pieces of variance decompositions, and we argue that they provide natural and insightful measures of connectedness among financial asset returns and volatilities. We also show that variance decompositions define weighted, directed networks, so...

In the work of the Basel Committee there has been a tradition ofdistinguishing market from credit risk and to treat both categories independentlyin the calculation of risk capital. In practice positionsin a portfolio depend simultaneously on both market and credit riskfactors. In this case, an...

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...

In this paper we investigate the interaction between a credit portfolio and another risktype, which can be thought of as market risk. Combining Merton-like factor models forcredit risk with linear factor models for market risk, we analytically calculate their interriskcorrelation and show how...
