This is a lurking crisis for stocks

Just when you thought it was safe to forget about Europe, the Italian stock market gets pummeled on fears of another government crisis. This as the Greek finance minister hints his country may need another €10 billion in aid.

Former Italian Prime Minister Silvio Berlusconi's political party, Il Popolo della Libertà, said that should their leader be ousted from parliament, they would seek to oust the government from power. Berlusconi, one of the world's richest men, was convicted of tax evasion last year. He is scheduled to serve a one-year conviction which could potentially bar him from political office. And that's something his party won't stand for, causing them to threaten to bring down the government. In turn, that brought down the Italian stock market by 1.6%.

Italy, a country with €2.1 trillion debt, is the third-most indebted nation on earth behind the US and Japan. Italy's debt is nearly 130% of its entire GDP and the current government's instability won't help matters.

Meanwhile across the Ionian Sea, Greece's Finance Minister Yannis Stournaras told Greek newspaper Proto Thema that the country could need another bailout in 2014, but it would be the "small" amount of €10 billion. In 2010, Greece received €110 billion and in 2012, another €140 billion in bailouts from the International Monetary Fund and larger, more stable European countries, particularly Germany.

Spain, too, is feared to be close to a crisis point. Though its GDP contracted "only" 0.1% the in the last quarter compared with the previous year, prospects for future growth remains grim. Spain's unemployment rate is at 26%, a little less than Greece's 27%. But, Spain has more than four times Greece's population of 11 million.
