European Commission anti-trust investigators are probing whether banks are deliberately blocking non-bank competitors from accessing customer account data, reports Finextra. The Commission confirmed that it carried out unannounced inspections in Holland and Poland after allegations of anti-competitive practices "aimed at excluding non-bank owned providers of financial services by preventing them from gaining access to bank customers' account data, despite the fact that the respective customers have given their consent to such access." Italy's finance minister said he had doubts about the European Central Bank's plan to make it costlier for banks to hold bad loans through forcing them to increase provisions for non-performing loans, reports the FT. Pier Carlo Padoan was echoing concerns from other Italian politicians and officials that the proposed new guidelines would hamper credit creation and threaten Italy's economic growth. "The swift timeline would disproportionately hurt Italy, where many bankruptcy cases remain unresolved for longer," reports the FT. The European Central Bank has completed its latest round of eurozone stress tests, and says banks won't be required to raise fresh capital to guard against a sudden rise in interest rates, reports the Wall Street Journal.
