GREECE - Greece’s financial crisis has come back to the boil as Athens draws up emergency plans to stabilize the banking system, raising concerns that the country may ultimately need a fourth EU rescue to escape its depression trap. Global risk aversion and contagion from Italy’s parallel banking drama has lifted a lid on the festering legacy of bad debts, and exposed the implausible methods employed by Greek regulators and the EU-led troika to camouflage the problem. Greek bank shares slumped a further 6 percent on Tuesday after five days of falls. They are now down by 60 percent since May, chiefly on fears of drastic state intervention to shore up thinning capital buffers.
