LONDON, Sept 10 (Reuters) - World stocks fell on Wednesday while safe-haven government bonds and the yen rose after U.S. investment bank Lehman Brothers <LEH.N> disappointed investors with a bigger-than-expected quarterly loss.
Lehman, a casualty of the credit crunch, posted a preliminary quarterly loss of $5.92 a share, compared with Reuters Estimates of a loss of $3.43.
The bank also said it would spin off its commercial real estate assets into a new, separate public company, adding it is examining all strategic alternatives [
].Lehman's announcement offered the latest piece of negative news for risky assets. The market correction of the past 12 months has weighed on investor sentiment and threatened to kick major economies into recession.
"Overall, the deleveraging will continue, and if that's the case, more assets will have to be written down further and credits will remain tight. All that doesn't spell well for the stock market," said Lou Brien, market strategist at DRW Trading in Chicago.
The FTSEurofirst 300 index <
> fell 1.4 percent while the MSCI main world equity index <.MIWD00000PUS> lost 0.7 percent, approaching last week's two-year low.U.S. stock futures <SPc1> were down 0.4 percent, indicating a firmer open on Wall Street later.
Lehman shares erased early gains to trade lower in pre-market dealings, also coming under pressure after its talks to raise fresh capital from Korean Development Bank collapsed earlier.
"Lehman's meltdown won't probably be the last negative episode of this credit crisis," said Christian Jimenez, president of Imene Investment partners in Paris.
"The consequences of the troubles in the banking system will continue to drag the economy, and stocks will stay in the doldrums for a while before we see any durable rebound."
DOLLAR RISES
After dipping in and out of positive territory for most of the session, the dollar <.DXY> rose 0.2 percent against a basket of major currencies, having hit a one-year high earlier this week.
The dollar has been benefiting from expectations that growth outside the United States is deteriorating and interest rates will fall, especially in Europe.
The low-yielding yen rose 0.1 percent to 106.78 per dollar <JPY=>, while the December bund future turned positive to trade up 12 ticks <FGBLc1>.
Emerging sovereign spreads <11EMJ> widened 4 basis points while emerging stocks <.MSCIEF> fell 1.8 percent to a fresh 18-month low.
U.S. light crude <CLc1> rose 0.3 percent to $103.62 a barrel, rebounding from Tuesday's five-month low after OPEC agreed to an unexpected production cut.
Gold <XAU=> slipped to $771.45 an ounce.
