This paper contains an analysis of the level of security of banks operating in Poland, with forms of the ownership taken into account. The results of the analysis have shown specificity of our country when compared to research already published. During volatile conditions in global markets nearly constant level of security of the cooperative banks and high dynamicity of indicators of commercial banks should be pointed out. Both BFG safety and the Z-score indexes lead to the conclusion that the financial crisis has highlighted the weakness of basing the security of banks on apparent, above-average financial results and used leverage, with the simultaneous abandonment of strengthening the capital base and of maintaining quality of loan portfolios.
