 NEW YORK, Aug 12 (Reuters) - Global stocks slumped and the
dollar strengthened on Thursday after weakness in the U.S. jobs
market and sour Greek data sapped the appetite for risk and
sent yields on safe-haven debt in Europe to an all-time low.
                                
 The number of American workers filing new claims for
unemployment insurance unexpectedly rose to its highest level

 In Greece, flash estimates for gross domestic product in
the second quarter showed the economy shrank more than expected
and unemployment climbed to 12 percent, reflecting the pain of
measures taken to overcome the country's fiscal crisis.

 "Right now, there is no short-term catalyst for economic
optimism," said Guy LeBas, chief fixed-income strategist with

 Jessica Hoversen, a fixed-income and currency analyst at MF
Global in Chicago, said markets are re-pricing slower growth
outside the United States, spurring dollar appreciation.
                                
 "Investors were aware of a slowdown in the U.S. economic
recovery, but now there are concerns other economies won't be
able to decouple from slower growth here and in China,"
Hoversen said.
