What is the relationship between bank fragility and competition during a period of market turmoil? Does market power in European banking involve extra-gains after discounting for the cost of government intervention? We answer these questions in the context of Eurozone banking over 2005-2012 and show that greater market power increases bank stability implying aggregate extra-gains of 57% of EU12 gross domestic product for the banking sector after discounting for the costs associated with government intervention. The negative influence of competition on bank stability is non-monotonic and reverses for lower degrees of competition. Capital injections, guarantees and asset relief measures elicit greater bank soundness.
