Attributing ratings to the top-20 owners, we construct a Risk-Weighted Ownership index (RWO) to measure the profitability and risk-taking behaviour of the ownership structure at banks. Collecting data from 19 European countries plus the UK over the 2008-2017 period, preliminary results show strong evidence that RWO measures are significant in explaining bank performance and risk, at both an accounting and a market-based level. Overall, these results suggest that not only markets and regulators should look at bank's owners: instead, it is far more relevant to assess the contribution carried by top-owners to bank risk, both individually and collectively.
JEL Classification: G21, G32period. First of all, we aggregate data of owner identity and percentages of ownership. Second, we gather the ratings released by Credit Rating Agencies (CRAs) -when available -or calculate it by referencing to either the Bank Z-Score or the Altman Z-Score (depending upon the owner's identity, whether financial or non-financial), based on the hypothesis that credit risk is correlated with equity risk (recently: Bai et al. 2017;Bekaert and Hoerova, 2016;Han et al., 2017). Where it was not possible to assign an idiosyncratic rating, we opted to attribute the rating of the country (systematic rating).On this dataset, we measure the RWO by assigning weighting coefficients pursuant to the Basel 1 framework, in relation to each owner's identity only, or Basel 2, by considering each owner's rating too. Then, we account for the effect of the single owner on the ownership structure by multiplying Basel coefficients by the percentage stake in the bank's capital. Hence, we can build two types of RWO index: one encompassing the sole identity of top-20 owners, another considering their "quality" too.Controlling for other corporate governance characteristics and regulatory environment, our preliminary results show strong evidence that RWO measures are relevant in explaining bank performance and risk, at both an accounting and a market-based level.The relevance of our findings is twofold. First, the RWO might be used as an early-warning indicator to signal when increasing the level of risk in bank decision-making is expected. This yields many remarkable implications in terms of stock market performance and volatility: also, considering the cross-correlation between financial markets. To policymakers, our results suggest that regulators, who already supervise banks' ownership structure, should not only look at whom owns the bank but, also, devote particular attention to analysing the risk appetite of potential owners, still within the context of the already-existing shareholding base.Our paper contributes to the emerging body of research by investigating the ways in which the ownership structure and specific categories of owners affect a bank's risk-taking. Compared to the extant literature, our paper is the first to propose a methodology to measure the risk-return profile of a bank's shareholding base as a driver of ex-ante risk-taking. In addition, we...
