NEW YORK, Jan 27 (Reuters) - The U.S. dollar rose on Wednesday to a six-month high against the euro and bond prices fell on worries over Greece's fiscal problems amid a renewed bid for safe-havens after a surprise drop in U.S. sales of new home.
The stronger dollar helped knock down the price of gold, oil and industrial metals as investors were cautious ahead of a policy announcement later in the day from the U.S. Federal Reserve. [
]Investors were also awaiting U.S. President Barack Obama's first State of the Union address at 9 p.m. (0200 GMT Jan. 28), when he is expected to promise more jobs creation and a slimmed budget deficit.
U.S. stocks fell after new home sales dropped unexpectedly in December, while heavy equipment maker Caterpillar Inc <CAT.N> and diversified manufacturer United Technologies Corp <UTX.N> provided guarded outlooks for the months ahead. [
]European shares fell, with banks the main drag following poor quarterly results from Spanish lender BBVA <BBVA.MC>.
"There is risk aversion about extending capital into the market place," said Craig Peckham, equity trading strategist at Jefferies & Company in New York.
Peckham said there was concern about potential changes in an expected statement by the Federal Open Market Committee at about 2:15 p.m. (1915 GMT) after Federal Reserve policy makers conclude their two-day meeting. The Fed is expected to leave interest rates near zero percent.
Obama's speech also was playing on investors' nerves.
"We've got some jitters about what we may get out of the State of the Union tonight," said Peckham.

> index of leading European shares closed down 0.9 percent at 1,013.83 points.Concerns over Greece weighed on all markets. The spread of the 10-year Greek bond yield over benchmark German Bunds rose to its highest since Greece adopted the euro currency in 2001.
"Greece is a great problem," said Giuseppe-Guido Amato, strategist at Lang & Schwarz in Frankfurt.
"If the uncertainty related to Greece is increasing then you see the dollar firm against the bunds. The strengthening of the dollar is correlated with falling markets."
Greece denied press reports it had chosen Goldman Sachs <GS.N> to sell up to 25 billion euros ($35 billion) of bonds to China, though it reiterated plans for an investor roadshow in Asia.
Greek government bonds were crushed after the denial.
"The real issues in the market are: what's going on with Greece; what the Fed is going to say later today. Also, they're scared about Obama's speech tonight and the attacks on the banks, and so on," said James Combias, head of government bond trading at Mizuho Securities USA, in New York.
He noted that U.S. home sales added to pressures but remained a lesser factor in the markets.
The benchmark 10-year U.S. Treasury note <US10YT=RR> was up 3/32 in price to yield 3.61 percent.
In early trading, the euro <EUR=> slipped 0.23 percent to $1.404 after hitting a low of $1.4022, the lowest since the end of July, according to Reuters data.

Oil prices fell toward $74 a barrel, pressured by a mixed inventory report from the United States and a stronger dollar. [
