NEW YORK, Oct 9 (Reuters) - U.S. Treasuries prices rose onTuesday as bleak views of global growth and the upcomingearnings season prompted investors to dump riskier assets andpour money into safe havens.

The International Monetary Fund warned that the UnitedStates faces meager growth of about 2 percent this year and nextand predicted the euro zone economy would shrink 0.4 percent in2012. It downgraded its outlook on China, the world'ssecond-largest economy.

The fund, one of Greece's main lenders, also said thatAthens would miss the five-year debt reduction target that is acondition for the country's 130 billion euro bailout.

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 overshadoweddata on Friday showing the U.S. jobless rate fell in Septemberto 7.8 percent, its lowest since January 2009. The LaborDepartment's September payroll report led to a sell-off inTreasuries on Friday and pushed benchmark yields to theirhighest in about two weeks.
