Banks adhere to strict rules regarding the quantity of regulatory capital held, but have some flexibility as to its composition. In this paper, we examine bank insolvency risk (distance to default) for listed North American and European banks over the period 2002-2014, focusing on sensitivity to capital other than common equity. Decomposing tier 1 capital into equity and non-core components reveals a heretofore unidentified variation in risk reduction capacity. Greater non-core tier 1 capital is associated with increased insolvency risk for larger and more diversified banks, impairing the risk reducing capacity of aggregate tier 1 capital. Overall tier 2 capital is not linked with insolvency risk, although a conflicting relationship is isolated conditional on the level of total regulatory capital held. Finally, the association between risk and capital is weakened when the latter is defined relative to risk-weighted assets.
