The euro appreciated vis-à-vis the U.S. dollar today as the single currency tested offers around the US$ 1.4195 level and was supported around the $1.4125 level.  Greece won some confidence back from the markets today after floating €8 billion in new bonds in a transaction that was about three times oversubscribed - an affirmation that Greece's credit concerns may be more manageable than most dealers believed last week.  Still, there are concerns that sovereign credit ratings may suffer more in the eurozone with Portugal on traders' radar.  Data released in the eurozone today saw German GfK February consumer sentiment decline to 3.2 from 3.4 in January.  Also, EMU-16 factory orders increased sharply in November, up 2.7% m/m and off 0.5% y/y, the largest monthly increase since July 2009.  Most European regulators are applauding the Obama administration announcement last week that it will drastically attempt to alter the regulatory landscape of banking institutions in the U.S.  but have also said they have no plans to follow suit at this time.  In U.S. news, data released in the U.S. today saw December existing home sales print at 5.45 million, below expectations and below November's print of 6.54 million.  This represented at 16.7% m/m decline. Also, the Dallas Fed's January manufacturing activity index improved to 8.3%.  After a rough few days, it appears Fed Chairman Bernanke will garner the Senate votes needed for reconfirmation later this week and this has been market-supportive today.  Dealers will pay extremely close attention to President Obama's State of the Union address on Wednesday night.  Euro bids are cited around the US$ 1.3885 level.
