NEW YORK, Oct 9 (Reuters) - U.S. Treasuries prices advancedon Tuesday as investors, worried about bleak views of globalgrowth and the upcoming earnings season, dumped riskier assetsto pour money into safe havens.
The International Monetary Fund, one of Greece's mainlenders, said in a report on Tuesday that Athens would miss thefive-year debt reduction target that is a condition for thecountry's 130 billion euro bailout.
The group also warned the United States faces meager growthof about 2.0 percent this year and in 2013 and predicted a 0.4percent contraction in the euro zone this year. It alsodowngraded its outlook on China, the world's second-largesteconomy.
The IMF outlook "was adding to the downbeat sentiment. Itwas a confirmation of slow growth globally," said GennadiyGoldberg, an interest rate strategist with TD Securities in NewYork. "That's why we are setting back into this trading range."
Key U.S. stock indexes also dropped as investors awaitedwhat many fear could be a disappointing earnings season.
"Earnings season is under way, and it does not bode to beparticularly good," said David Ader, head of government bondstrategy at CRT Capital Group in Stamford, Connecticut.
"I'd like to see whether that takes the edge off stocks andother risk assets," he added.
Thomson Reuters data through Friday showed 90 companies inthe S&P 500 have lowered outlooks versus 21 raised outlooks. Theresulting ratio of negative to positive outlooks of 4.3 is theweakest showing since the third quarter of 2001.
The concerns about Greece and global growth overshadowedFriday's government report that the U.S. jobless rate fell inSeptember to 7.8 percent, the lowest level since January 2009.The lower jobless rate and other surprisingly upbeat aspects ofthe Labor Department's September payroll report led to asell-off in Treasuries on Friday and pushed benchmark yields totheir highest levels in about two weeks.<^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
