The failure of Greek politicians to form a coalition government after the recent election was a trigger for a major collapse of confidence this week.
Many investors clearly believe the Greek government is closer to defaulting on its debt. Indeed the interim government revealed that 900 million euros was withdrawn from Greek bank accounts on Monday.
More recently, The Guardian has cited Spanish media reports that more than 1 billion euros had been withdrawn from the country's fourth-largest bank (Bankia) since it was nationalised on May 9.
While those reports have since been denied by Bankia there is an undeniable risk that other heavily indebted European countries could follow the path of Greece - and the Greek government is in a situation where it may have to finally consider abandoning the Euro currency block.
How the situation plays out over the coming weeks is uncertain but there is more pressure on the US Federal Reserve Bank to introduce more quantitative easing measures.
