* Wall Street little changed as uncertainty rules
* Italian banks in focus after a capital increase (Updates with U.S. markets' open)
By Barani Krishnan
NEW YORK, March 29 (Reuters) - European banking shares helped lead world stocks lower on Tuesday after an Italian bank announced a capital increase, while the dollar rose on comments by a Federal Reserve official and the yen hit post-intervention lows.
U.S. stocks were slightly lower as many investors, cautious about continuing global crises, bided their time before the quarter's end.
Oil prices fell, buffeted by continuing uncertainties over the political chaos in the Arab world and Japan's nuclear crisis.
World stocks as measured by MSCI <.MIWD00000PUS> were down 0.3 percent, mainly as a result of weakness in Europe. Emerging market stocks <.MSCIEF> gained around 0.3 percent.
The surprise announcement by Italy's UBI Banca's <UBI.MI> of a 1 billion euro ($1.4 billion) capital hike dragged down Italian banks on speculation that other lenders could be heading down the same road. UBI shares fell more than 10 percent. Investors also remained cautious ahead of the results of stress tests on Irish banks, due on Thursday.
The FTSEurofirst 300 <
> index of top European shares was down 0.3 percent."We are still very cautious on the banking sector as a whole," said Felicity Smith, fund manager at Bedlam Asset Management. "The big problem is that they need to hold more capital and that means in future, even if the economy grows, the returns they generate would be lower."
Volume has begun to fall on European bourses in line with 2011 lows on Wall Street.
The Dow Jones industrial average <
> was down 12.83 points, or 0.11 percent, at 12,185.05. The Standard & Poor's 500 Index <.SPX> was down 3.74 points, or 0.29 percent, at 1,306.45. The Nasdaq Composite Index < > was down 5.25 points, or 0.19 percent, at 2,725.43."The quarter is ending with a lot of uncertainties out there, resulting in messy intraday moves at the same time that nothing is really happening," said Michael Shaoul, chairman of the New York-based Marketfield Asset Management, which oversees $973 million.
"There's nothing obvious about what investors need to do in this environment, and that's why you're seeing such low volume," he said. "No one has any reason to recommit capital."
EURO/DOLLAR
The dollar rose against the euro on Tuesday after the president of the St. Louis Federal Reserve Bank, James Bullard, said the Fed's $600 billion asset purchase program could be trimmed by some $100 billion. [
] .The euro <EUR=> hit a session low of $1.4060 on EBS trading platform after falling through reported bids at $1.4080. It last traded at $1.4064. Traders said reported sovereign bids at $1.4050 could limit losses in the single currency, however.
Portugal's debt remained under pressure, with yields on its 10-year bonds near record levels above 8 percent, complicating the country's attempts to avoid a European Union bailout.
The dollar extended gains against the euro after data showed U.S. single family home prices fell for a seventh straight month in January, offering fresh evidence that the housing market recession in the United States was not over yet. [
].Meanwhile, the dollar and euro both reached their highest levels against the yen since since March 18, when the Bank of Japan and other major central banks intervened to stop runaway yen gains.
The dollar rose to high of 82.42 yen <JPY=EBS> on trading platform EBS. The euro rose to 115.86 <EURJPY=R> .It was on course to test 116.03, above which would mark a 10-month high.
In commodity markets, Brent crude for May delivery <LCOc1> was 39 cents lower at $114.41, after earlier falling more than a dollar. U.S. light crude <CLc1> dropped a dollar before paring losses to $103.62, down 36 cents.
Analysts said Japan's lack of progress in containing the nuclear crisis was likely to delay the world's third-largest oil user's return to full industrial strength, but the downside for oil prices could be limited by unrest in the Middle East.
"We have two factors that are countervailing," said Harry Tchilinguirian, analyst at BNP Paribas.
"There is a risk premium in the Middle East built in on risk of further contagion. On the other hand we have the fact Japan is a major component of the global supply chain, so the potential for a price correction in the second quarter remains."
U.S. gold fell further on Tuesday, as the prospect of interest rate increases undermined its appeal as an inflation hedge and copper slipped as demand from top consumer China wanes. (Additional reporting by Atul Prakash, Jessica Mortimer and Richard Leong; Editing by Leslie Adler)
