...the next global problem: portugal...

"Next on the radar will be Portugal. This nation has largely missed the spotlight, if only because Greece spiraled downward. But both are economically on the verge of bankruptcy, and they each look far riskier than Argentina did back in 2001 when it succumbed to default.

Portugal spent too much over the last several years, building its debt up to 78 percent of G.D.P. at the end of 2009 (compared with Greece’s 114 percent of G.D.P. and Argentina’s 62 percent of G.D.P. at default). The debt has been largely financed by foreigners, and as with Greece, the country has not paid interest outright, but instead refinances its interest payments each year by issuing new debt. By 2012 Portugal’s debt-to-G.D.P. ratio should reach 108 percent of G.D.P. if the country meets its planned budget deficit targets. At some point financial markets will simply refuse to finance this Ponzi game.

The main problem that Portugal faces, like Greece, Ireland and Spain, is that it is stuck with a highly overvalued exchange rate when it is in need of far-reaching fiscal adjustment." aqui
