We derive a Z-score measure reflecting downside bank insolvency risk, drawing on a Chebyshev inequality in terms of the lower semivariance. As then illustrated empirically for US banks, this may provide a useful alternative, or robustness check, to the more commonly used Z-score measure based on the standard Chebyshev inequality.
