NEW YORK, Oct 9 (Reuters) - U.S. Treasuries prices advanced on Tuesday as investors, worried about bleak views of global growth and the upcoming earnings season, dumped riskier assets to pour money into safe havens.

The International Monetary Fund, one of Greece's main lenders, said in a report on Tuesday that Athens would miss the five-year debt reduction target that is a condition for the country's 130 billion euro bailout.

The group also warned the United States faces meager growth of about 2.0 percent this year and in 2013 and predicted a 0.4 percent contraction in the euro zone this year. It also downgraded its outlook on China, the world's second-largest economy.

The IMF outlook "was adding to the downbeat sentiment. It was a confirmation of slow growth globally," said Gennadiy Goldberg, an interest rate strategist with TD Securities in New York. "That's why we are setting back into this trading range."

Key U.S. stock indexes also dropped as investors awaited what many fear could be a disappointing earnings season.

"Earnings season is under way, and it does not bode to be particularly good," said David Ader, head of government bond strategy at CRT Capital Group in Stamford, Connecticut.

"I'd like to see whether that takes the edge off stocks and other risk assets," he added.

Thomson Reuters data through Friday showed 90 companies in the S&P 500 have lowered outlooks versus 21 raised outlooks. The resulting ratio of negative to positive outlooks of 4.3 is the weakest showing since the third quarter of 2001.

The concerns about Greece and global growth overshadowed Friday's government report that the U.S. jobless rate fell in September to 7.8 percent, the lowest level since January 2009. The lower jobless rate and other surprisingly upbeat aspects of the Labor Department's September payroll report led to a sell-off in Treasuries on Friday and pushed benchmark yields to their highest levels in about two weeks. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The U.S. bond market was closed on Monday for to the Columbus Day holiday.

Safe-haven appetite for Treasuries was mitigated by some selling by bond dealers in anticipation of this week's $66 billion in coupon supply.

In addition, the Treasury Department sold $32 billion in three-year notes on Tuesday at a high yield of 0.346 percent.

The Treasury Department will sell $21 billion in 10-year debt on Wednesday and $13 billion in 30-year bonds on Thursday.

In addition, the Federal Reserve resumed transactions under its Operation Twist program, which involves selling shorter-dated Treasuries and purchasing longer-dated issues in a bid to hold down long-term borrowing costs to help the economy. It bought $1.89 billion in Treasuries due in February 2036 to August 2042.

Fed Vice Chairwoman Janet Yellen was scheduled to speak at 8:30 p.m. (0030 GMT) about sovereign risk and financial markets at an event sponsored by the IMF and the Japanese Ministry of Finance.

"The market is struggling with a lot of moving parts," said Robert Tipp, chief investment strategist with Prudential Fixed Income in Newark, New Jersey. "At the end of the day, we'll be in a pretty tight trading range."

On the open market, benchmark 10-year notes


up 06/32 in price to yield 1.713 percent, down from 1.748 percent late on Friday, the highest level since Sept 24.

Wall Street stocks fell, with the Standard & Poor's 500 index

0.77 percent lower. Traders will focus on the earnings of Dow component Alcoa
