Objectives & Core Topics

This master's thesis aims to estimate the systematic component of credit spreads in the EUR-denominated corporate bond market to provide insights for debt beta calculations in business valuations. The research decomposes credit spreads into their constituent parts—specifically targeting the systematic risk portion—and investigates how these components behave under different economic regimes, such as financial crises.

• Decomposition of EUR-denominated corporate bond credit spreads.
• Estimation and comparison of systematic credit spread components.
• Investigation of regime-dependent spread behavior during economic crises.
• Derivation of implications for debt beta in business valuation models.

Excerpt from the Book

Summary of Chapters

1 Introduction: Introduces the EUR-denominated corporate bond market and the central phenomenon known as the "credit spread puzzle," setting the stage for the systematic decomposition of credit spreads.

2 Literature review: Provides an overview of existing theoretical and empirical approaches for measuring systematic risk and identifying its determinants within credit spreads.

3 Systematic risk and debt beta: Examines the theoretical foundations and standardized instructions for incorporating debt beta into business valuation processes.

4 Corporate bond risk: Analyzes the primary risk components that bond investors seek compensation for: credit risk (default and migration risk), liquidity risk, and systematic risk.

5 Empirical analysis: Presents the methodology and results of the study, estimating the systematic credit spread and analyzing how these spreads vary across different economic crisis regimes.

6 Implications on debt beta: Discusses the practical consequences of the empirical findings on the estimation and application of debt beta in business valuations.

7 Conclusion: Summarizes the key insights of the thesis regarding the systematic risk component in the European corporate bond market and provides suggestions for future research.

A Appendix: Contains supplementary data, technical calculations, and robustness checks for the empirical analysis.

Frequently Asked Questions

What is the primary motivation for this research?

The study is motivated by the "credit spread puzzle," where observed corporate bond credit spreads exceed historical default rates. The thesis aims to clarify the systematic component of these spreads to assist practitioners in correctly calculating debt beta for business valuations.

Which market is analyzed in the thesis?

The focus of the research is the EUR-denominated corporate bond market, specifically analyzing Non-Financials to provide an empirical basis for understanding systematic risk in this region.

What is the central research question?

The central question is how the systematic component of EUR-denominated corporate bond credit spreads can be estimated and whether this systematic risk is dependent on different economic regimes, such as crisis periods.

Which methodology is employed in the study?

The thesis utilizes a reduced-form model approach to decompose credit spreads, combined with a Fama-French-5-Factor regression to determine the impact of systematic priced factors on residual spreads.

What is covered in the empirical analysis section?

This section details the data set compilation, the specific steps for estimating the default risk premium, the calculation of the systematic credit spread, and the statistical analysis of spread behavior across different economic cycles.

How is "systematic risk" characterized in the context of the study?

Systematic risk is defined as the component of the credit spread that is driven by aggregate market movements and financial factors (such as stock market returns) which cannot be diversified away by holding a bond portfolio.

How does the choice of the transition matrix affect the results?

The study finds that the results are highly sensitive to the chosen transition matrix and recovery rate inputs, noting that lower default probabilities in Europe compared to the US drive variations in the resulting credit spread estimates.

What does the study conclude regarding the "debt beta" in business valuation?

The findings suggest that the systematic risk component is non-negligible, and practitioners should consider that the systematic portion of the credit spread may be larger than previously assumed, which influences the calculation and relevance of debt beta.
