While market participants last week expected the unveiling of the specifics of the Greece bailout plan, European officials merely continued their tough stance on Greece.

They reiterated their expectations that Greece should slash its budget deficit to 8.7 percent of the Gross Domestic Product (GDP) for 2010, which is a 4 percentage points reduction from the 12.7 percent 2009 figure.

By 2012, they expect Greece slash its budget deficit below the permitted European Union ceiling, which is 3 percent of GDP.

Jean-Claude Juncker, the Eurogroup chief from Luxembourg, warned that if Greece's debt reduction plans are not on target by March 16, additional measures may need to be considered.

In protest of the austerity measures, Greek customs officials began a 3-day strike today. The spread between the yield of Greek and German sovereign debt widened modestly today.

Although most ADRs of European financial firms are trading higher, those of the National Bank of Greece (NYSE:NBG) lost 4.35 percent.
