5. Conclusion
This study investigates the relationship between financial penalties and banks’ profitability and stock performance. More specifically, in the first part of our study, we analyze the connection between the return on average assets, pre-tax as well as after-tax, and financial penalties. In the second part of our study, we examine the stock market performance of banks facing financial penalties. To that end, we consider the one-year buy-and-hold return and abnormal returns. We use a unique dataset containing hand-collected information on the amount, the type, and the date of each financial penalty imposed on the banks included in our sample. This dataset includes 671 financial penalties paid by 68 international banks between 2007 and 2014.
Our analyses provide evidence of a significant negative relation between financial penalties and the pre-tax profitability of banks. However, banks can – depending on national tax laws, the judicial system, and the type of misconduct – deduct some financial penalties from their taxable earnings. Especially in the case of the US banks examined here, we observe that the relation between financial penalties and profitability described above changes dramatically when after-tax profitability is considered. In contrast, profitability of the European banks is still significantly related to financial penalties. Also, we find evidence that financial penalties are negatively related to profitability in the following year due to a lower income-to-total-assets ratio.
