Using data for more than 160 countries in the period 1997–2010, we explore the impact of large-scale natural disasters on the distance-to-default of commercial banks. The financial consequences of natural catastrophes may stress and threaten the existence of a bank by adversely affecting their solvency. After extensive testing for the sensitivity of the results, our main findings suggest that natural disasters increase the likelihood of a banks’ default. More precisely, we conclude that geophysical and meteorological disasters reduce the distance-to-default the most due to their widespread damage caused. In addition, the impact of a natural disaster depends on the size and scope of the catastrophe, the rigorousness of financial regulation and supervision, and the level of financial and economic development of a particular country.

We examine the effectiveness of the financial sector rescue packages provided by the national governments during the 2008 financial crisis. This study questions the implicit assumption that government interventions have an uniform effect on the default risk of individual banks. After testing the results for sensitivity, our main findings suggest that there exists a significant negative relationship between the announcement of the financial sector rescue packages and the daily change of the credit default premium. However, quantile regressions show that the effectiveness of these packages differs across banks: most interventions do not decrease the risk of intermediate to low-risk banks, while they do reduce the risk of high-risk banks. Besides, we find that interventions aimed at specific financial institutions are more effective in restraining banking risk than broad interventions taken to stabilize the financial market as a whole.

It has been argued that central bank independence (CBI) may not only be beneficial for reaching the objective of price stability, but also for maintaining financial stability. Greater independence from external pressure implies that central banks are less politically constrained in acting to prevent financial distress, while it also will allow them to act earlier and more decisively when a crisis erupts. We estimate the relation between CBI and a newly constructed measure of financial instability using a dynamic panel model for the period 1985–2005 with a large set of control variables. We find a significant and robust negative relation between CBI and financial instability, which is mostly due to political independence.

Using data for more than 200 banks from 21 OECD countries for the period 2002–2008, we examine the impact of bank regulation and supervision on banking risk using quantile regressions. In contrast to most previous research, we find that banking regulation and supervision has an effect on the risks of high-risk banks. However, most measures for bank regulation and supervision do not have a significant effect on low-risk banks. As banking risk and bank regulation and supervision are multi-faceted concepts, our measures for both concepts are constructed using factor analysis.
