LONDON, Feb 10 (Reuters) - World stocks fell after five days of gains on Tuesday as investors fretted over U.S. plans to boost the economy and save its banks.
The euro also wobbled after Russia denied seeking to restructure as much as $400 billion in companies' foreign debts after a Japanese newspaper said a local banking lobby group had asked the government to help negotiate with creditors.
U.S. President Barack Obama has been taking his case directly to the public to push Congress to act in the coming week on an $838 billion economic stimulus package.
The U.S. Senate has moved closer to passing the bill, setting up a vote on it version of the package on Tuesday.
But delays in fashioning compromise legislation, a mix of government spending and tax breaks, could prevent Congress from delivering a final bill to Obama by his deadline this weekend.
Questions were also being asked about the future of a U.S. bailout plan for banks.
"It's starting to seem as if the economic stimulus plan will be approved one way or another, but the bank bailout is really important, and this uncertainty is growing," said Takashi Ushio, head of the investment strategy division at Marusan Securities.
One result has been to make investors cautious.
World stocks as measured by MSCI <.MIWD00000PUS> were down 0.8 percent on Tuesday, although they gained more than 5 percent over the previous five sessions.
The FTSEurofirst 30 <
> lost 1.4 percent, also stirred by mixed reaction to a roughly $7 billion net fourth quarter loss from UBS <UBSN.VX>.Earlier, Japan's Nikkei stock average <
> slipped 0.3 percent or 23.09 points to close at 7,945.94. The broader Topix < > fell 0.1 percent to end at 778.10.
RUSSIA WORRY
The euro fell against the dollar and yen but trimmed some losses after Russia denied a media report that Russian banks will ask Moscow to help them restructure its corporate debt owned to foreign creditors.
But investors were wary of taking large positions ahead of an eagerly awaited U.S. plan to shore up its banks. U.S. Treasury Secretary Timothy Geithner is expected to unveil the outline of the plan later on Tuesday.
The euro was down 0.8 percent at $1.2903, after falling to $1.2811 <EUR=>, according to Reuters data. Against the yen, the euro fell 0.6 percent to 118.27 yen <EURJPY=R> after hitting a low of 116.72 yen.
Euro zone government bonds rose as equities fell.
Two-year Schatz yields <EU2YT=RR> slipped 2.9 basis points on the day to 1.405 percent, while 10-year Bunds yielded <EU10YT=RR> 3.362 percent, down 4.4 basis points.
These moves saw the 2-10 year yield curve flatten slightly to 195 basis points, off Monday's high above 200 basis points -- the steepest since the introduction of the euro in 1999.
