Measuring bank risk : Forward-looking z-score

While the z-score has been widely used to evaluate bank risk, it is criticized as a backward-looking measure. We propose a forward-looking method to construct the z-score by incorporating analyst forecasts. Empirical results show that the forward-looking z-score can predict the movement of the standard z-score one quarter ahead of time, and its predictive ability on banks' downward risk is better than the standard z-score. Moreover, we find that the predictive ability of the forward-looking z-score improves after the Dodd-Frank Act of 2010, especially for large banks, showing the consequences of strengthened regulation and transparency. The forward-looking z-score is also significantly associated with the probability of default and market-based risk measures and can provide predictive signals for banks' future profitability. Overall, our findings suggest that the forward-looking z-score mitigates the shortcomings of the standard z-score and provides a reliable early warning signal for banks' future risk and performance
