Greek banks saw deposit outflows of about 400 million euros (289.17 million pounds) on Monday as the pace of withdrawals picked up from last week after talks with the country's creditors over an aid-for reforms deal broke down on Sunday, bankers said. "There is worry but the outflows were rather contained, not as bad as feared in the context of a bad climate after negotiations hit an impasse," one banker told Reuters, declining to be named. Athens's tortuous talks with its euro zone partners and the International Monetary Fund over the last five months have fed uncertainty and fears that capital controls could be introduced, unnerving savers who have been withdrawing around 200-250 million euros daily from Greek banks in recent weeks.
