Eight banks have failed Europe's bank stress test designed to assess whether they could survive another economic crisis, banking regulators said Friday according to dpa. A total of 90 banks - representing 65 per cent of the assets of Europe's banking sector - have been subject this year to the tests, which leaders hope will help ease the tensions triggered by the eurozone's debt crisis. The eight banks - one from Austria, five from Spain and two from Greece - fell short of having the required 5-per-cent core tier one capital, the London-based European Banking Authority (EBA) said releasing the report.
