Greece's deepening debt crisis:Worries about Greece’s ability to roll over its maturing debt are giving way to bigger fears

Optimists are still confident that the government can raise enough funds in the next six weeks to stave off default, though at a high cost. The government has more than €13 billion in cash, enough to refinance maturing debt and fund the budget deficit during April. It needs to raise another €10 billion-12 billion in May. The likely borrowing requirement for the remainder of the year, around €25 billion, is spread more evenly. “If we can get over the May borrowing hump, it’s a relatively smooth cruise for the rest of the year,” says one trader in Athens.
