* U.S. stocks fall on soft economic data
* Euro higher on European outlook; Spanish, Greek yields steady
* U.S. Treasury yields fall
NEW YORK, Nov 30 (Reuters) - Major U.S. stock indexes and U.S. Treasury yields fell on Friday as concern about the stalemate in crucial U.S. budget talks and soft U.S. economic data added to worries about slowing economic growth in the world's largest economy.
The euro fell to session lows against the dollar after data on U.S. consumer spending and income fell short of expectations , though it later recovered as investors focused on a better outlook for Europe after a deal between Greece and international lenders earlier in the week.
U.S. President Barack Obama, reiterating his re-election campaign theme of protecting the middle class, heads to Pennsylvania on Friday to argue that Republicans could spoil Christmas by driving the country over the "fiscal cliff" of tax hikes and spending cuts set to kick in early next year.
"Washington brinkmanship and a delay in reaching an agreement on the 'fiscal cliff' are likely to rattle markets. These risks and uncertainties are likely to keep markets volatile," said John Praveen, chief investment strategist at Prudential International Investments Advisers LLC.
The Dow Jones industrial average was down 22.42 points, or 0.17 percent, at 12,999.40. The Standard & Poor's 500 Index was down 3.25 points, or 0.23 percent, at 1,412.70. The Nasdaq Composite Index was down 9.58 points, or 0.32 percent, at 3,002.45.
The benchmark 10-year U.S. Treasury note was up 1/32, the yield at 1.616 percent. A private report on business activity in the Chicago area in November matched economists' forecasts, portending moderate growth for the U.S. economy. .
"These numbers were soft," said Ryan Sweet, senior economist with Moody's Analytics, shortly after the consumer spending data was released. "It's a sign that consumers are cautious. They are tightening their purse strings with the jobs market taking a step back. The 'fiscal cliff' will likely hit spending later even though it's not in the forefront of consumers' mind."
World and European stocks edged lower. The MSCI world equity index was down 0.1 percent at 332.02, though it was still near its highest level for November, having added almost 1 percent on Thursday.
The FTSEurofirst 300 index of top European shares also slipped 0.1 percent to 1,120.89, following Thursday's 1.1 percent gain, which took it to a four-month closing high.
European shares are on course for their best month since August and a sixth straight monthly gain as sentiment over the outlook for Europe has improved since a deal was reached on aid to Greece earlier this week.
Those signs have also helped the euro, which was up 0.3 percent against the dollar to $1.3012 after climbing to a five-week high. The single currency touched a seven-month high against the yen.
Strong demand at an Italian bond auction this week, which cut Rome's borrowing costs to a two-year low, and falls in Spanish bond yields have encouraged investors to return to European assets.
Spanish and Italian 10-year bond yields were stable on Friday at 5.334 percent and 4.48 percent respectively, well below their peak in July, when Spain's debt yielded more than 6 percent.
Earlier, MSCI's broadest index of Asia-Pacific shares outside Japan rose 0.6 percent to its highest level since March 1, after a monthly gain of 2.1 percent.
The U.S. fiscal crisis remains the center of focus in oil markets due to its potential impact on demand from the world's biggest consumer. Crude was up ahead of the weekend.
Brent crude slipped 0.1 percent to $110.60 a barrel, while U.S. crude rose 0.3 percent to $88.31 a barrel.
"No significant progress seems to have been made in the U.S. budgetary dispute, which has led to profit-taking, especially since oil is trading at the upper end of its trading corridor," said Commerzbank oil analyst Carsten Fritsch.
Gold fell to $1,714.14 an ounce, buffeted by uncertainty over the U.S. budget crisis.
