ATHENS/BRUSSELS (Reuters) – Greece can scrape together enough cash to meet its payment obligations into June, euro zone and Greek officials said on Wednesday, playing down fears of an imminent default as hopes receded of a deal with its creditors to release fresh aid. The European Central Bank raised its ceiling on emergency lending by the Greek central bank to Greek banks by 1.5 billion euros to 75.4 billion euros, giving them a bigger buffer to cope with deposit withdrawals, a banking source said.
