* World stocks slip as Europe falls, emerging rise
* Wall Street set for small gains
* Portugal debt, Italian banks in focus
By Jeremy Gaunt, European Investment Correspondent
LONDON, March 29 (Reuters) - Concerns about Italian banks dragged European stocks lower on Tuesday, undermining global gains, while earlier euro strength dissipated.
Wall Street looked set to open slightly higher.
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.
World stocks as measured by MSCI <.MIWD00000PUS> were down 0.2 percent, mainly as a result of weakness in Europe. The global emerging market component <.MSCIEF> gained around 0.2 percent.
Italian lenders were down sharply after UBI Banca's <UBI.MI> surprise announcement of a 1 billion euros ($1.4 billion) capital hike.
Analysts said there were concerns that other banks might follow suit, while investors also stayed cautious ahead of the results of stress tests on Irish banks, due on Thursday.
The FTSEurofirst 300 <
> index of top European shares was down more than half a 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.
Some of this may reflect continuing uncertainty about how the Japan disaster, turmoil in the Arab world and global monetary policy will play out. But it could equally be a case of locking in Q1 profits.
Investors have generally focused on the improving world economy, but the crises and worries about inflation may be taking some toll.
German consumer sentiment fell for the first time in 10 months going into April as concern about global issues and inflation hit households.
The forward-looking GfK consumer sentiment indicator, based on a survey of 2,000 Germans, fell to 5.9 for April from 6.0 for March -- but this was still slightly above the 5.8 expected by 27 economists polled by Reuters.
EURO
The euro was slightly firmer against the dollar after earlier strengthening on comments by European Central Bank President Jean-Claude Trichet that reinforced expectations for a rate rise next month.
The common currency had dipped on Monday after hawkish U.S. policymaker comments lifted the dollar, but it failed to break below $1.40 before it moved back up as Trichet said inflation was "durably" above the ECB's target. [
]Investors continued to focus on the prospect of higher rates and to shrug off the euro zone debt crisis, despite concerns about Portugal's ability to finance itself as the country prepared for a snap election. [
]The euro <EUR=> was up less than 0.1 percent at $1.4087.
