We then ask whether the cross section of the MES can help to identify ex ante, i.e. before a crisis unfolds, which institutions are the more likely to su¤er the most severe losses ex post, i.e. once it has unfolded. Unfortunately, using the recent crisis as a natural experiment, we …nd that standard balance-sheet metrics like the tier one solvency ratio are better able than the MES to predict equity losses conditionally to a true crisis.

Non technical summaryThe Finally, using the 2007-2009 crisis as a natural experiment, we ask whether the MES as measured before the crisis (i.e. taking an ex ante view) would have been useful to identify which institutions were the most likely to be severely hit should a crisis occur. Based on cross-sectional rank correlations as well as cross-sectional regressions, we conclude that some standard balance-sheet ratios already routinely monitored by regulators, like the ratio of tier-one capital to risk-weighted assets would have been more useful than the MES at predicting which banks were bound to su¤er the most severe equity losses during the crisis.3
