NEW YORK, Dec 19 (Reuters) - World shares rose to 17-month highs and the euro surged on Wednesday as hopes grew for a year-end budget deal in the United States and the economic outlook for Germany improved, but Wall Street faltered after its best two days of gains in a month.
A key business survey in Germany bolstered investor sentiment by suggesting that Europe's biggest economy was likely to bounce back quickly from a slowdown.
The growing German confidence lifted the euro to a 16-month high against the yen and an 8-1/2 month peak versus the U.S. dollar, while Brent oil rose toward $110 a barrel.
But despite a sense American politicians were getting closer to an agreement to avert the "fiscal cliff" - steep tax hikes and spending cuts that will take effect in the new year - it was not enough to push the broad U.S. equity market higher.
"The question has shifted to what a deal will look like and entail, and markets are taking a pause as we consider that," said Scott Eldridge, director of portfolio management at Caprin Asset Management in Richmond, Virginia.
"It seems like all the parties at the table have made steady progress, but it continues to drown out all the other noise in markets."
Strong results from Oracle lifted U.S. technology shares, but the S&P 500 struggled to extend its best two-day run in a month.
Investors gave little importance to data that showed U.S. homebuilding permits touched their highest level in nearly 4-1/2 years in November, pointing to strength in the housing market, even though ground-breaking activity dropped.
The Dow Jones industrial average was down 9.79 points, or 0.07 percent, at 13,341.17. The Standard & Poor's 500 Index was down 2.08 points, or 0.14 percent, at 1,444.71. The Nasdaq Composite Index was up 2.12 points, or 0.07 percent, at 3,056.65.

The FTSEurofirst 300 index rose 0.43 percent to a provisional 19-month closing high of 1142.35.
The better tone in global markets was supported by the U.S. Federal Reserve's efforts to boost the U.S. recovery, signs of growing economic momentum in China and talk that Japan is set for a policy shift to lift itself out of recession.
The latest German Ifo Institute survey of 7,000 firms bolstered this sentiment by finding that business confidence had improved for a second straight month in December, in part because of better export prospects.
The brighter outlook has pushed MSCI's all-country world equity index to levels last seen in July 2011. The index rose 0.42 percent to 342.87 on Wednesday, on track for its fifth straight weekly gain.
The yen also weakened to its lowest in more than 18 months against the dollar on expectations the Bank of Japan will ease monetary policy at the end of a two-day policy meeting on Thursday.
The euro rose 0.2 percent to 1.3257 to the dollar, a level not seen since April 2011, while against the yen it gained 0.41 percent to 111.82, its highest since August 2011.
