Greece is in danger of defaulting on its national debt as its bond market comes under increasing pressure, unless its European neighbors intervene.
Analysts believe that the shape of Greece's fiscal future – default or bail-out – could be decided in the coming days.
"We think an intervention over the weekend is a distinct possibility," wrote Stephane Deo, a UBS analyst based in London, in a note to investors.
He said that the falling price of Greek bonds "means that an external intervention may be unavoidable and could happen very soon as the situation is untenable."
He added that a cash injection from the International Monetary Fund is the "most likely scenario" and would solve the country's liquidity problem, at least for now.
