The course is aimed at providing the main tools for measuring and managing financial risks. We begin by defining the various types of financial risks and stress the need for their management through the analysis of losses and defaults of financial institutions in the recent past. The first type of financial risk we analyze is market risk, measured by the Value-at-Risk (VaR). We discuss the estimation of the main inputs surrounding the calculation of VaR and the possible methodologies available for determining the VaR of individual assets and portfolios. In doing so, we also elaborate on models for time-varying volatility and correlations. Alternative measures of risk are also analyzed.
The second half of the course focuses on credit risk. We first define the objects of interest in evaluating credit risk and explore several classes of models which have been proposed for its measurement. We then look at the derivative products that are available to transfer credit risk, such as credit default swaps, and discuss their pricing.
The course concludes with an overview of the regulatory capital requirements from the Basel Accords.
