Abstract

Analysing the database made available by the European Central Bank and by the European Banking Authority, we evaluate the Comprehensive Assessment (CA) (Asset Quality Review and Stress Test (ST)) of banks carried out in 2014. In a nutshell, the main results are: (i) risk-adjusted capital ratios are negatively related to the Asset Quality Review shortfall, but not to the ST shortfall, whereas the leverage ratio plays a significant role in both cases; (ii) the CA predominantly concentrated on traditional credit activity rather than on banks’ financial assets and (iii) the CA seems to be characterized by double standards. The Asset Quality Review was severe with banks operating in non-core countries, while medium-sized banks were either riskier or were treated severely in both exercises. The analysis leads to a puzzle: comparatively, the assessment per se led to significant adjustments for solid banks and large shortfalls for weak banks. The puzzle can be resolved by referring to the legacy of the country’s former supervisory activity and to the low level of capitalization of weak banks mostly in peripheral countries.
