NEW YORK, Jan 24 (Reuters) - Global stock markets posted gains on Thursday, hoping that plans to rescue ailing bond insurers and provide tax breaks to consumers would prevent new credit losses and breathe fresh life into the U.S. economy.
Congress and the White House on Thursday agreed on the details of a $150 billion economic stimulus package. U.S. Speaker of the House of Representatives Nancy Pelosi said it will include tax rebates for up to 117 million U.S. families.
"I think investors are encouraged they came up with an agreement in principle, in quick fashion, and the speaker's remarks were encouraging in that she said it was bipartisan," said Angel Mata, managing director of listed equity trading, Stifel Nicolaus Capital Markets in Baltimore.
"When they started speaking, (the market) picked up momentum ... whether it's momentum or short-covering or value buyers, they're coming in," he said.
A surprise decline in the number of U.S. workers applying for jobless benefits also induced optimism, dulling demand for safe-haven government bonds, though claims of a massive trade fraud at a major bank added to financial worries.
Oil futures rose above $89 a barrel <CLc1>, in tandem with equities' rebound, while the dollar tumbled against the euro.
On Wall Street, the Dow Jones industrial average <
> was up 108.44 points, or 0.88 percent, at 12,378.61. The Standard & Poor's 500 Index <.SPX> was up 13.55 points, or 1.01 percent, at 1,352.15.The Nasdaq Composite Index <
> was up 33.32 points, or 1.44 percent, at 2,349.73, boosted by a 10.3 percent rise in Qualcomm Inc <QCOM.O> shares a day after the mobile phone clip maker posted a rise in quarterly profit.Also lifting market spirits was news that New York's insurance regulator had pressed major banks to put up billions of dollars in an effort to rescue wobbly bond insurers.
Bond insurers guarantee the interest and principal on an estimated $2.5 trillion of bonds. The debt they underwrite shares the investment-grade ratings many of these firms carry, so downgrades due to losses would drag debt ratings down as well.
Analysts worry that this could force investors to dump billions of dollars of municipal bonds, repackaged loans and the like on to markets, sending borrowing costs soaring and forcing more investor writedowns.
Talk of an insurance bailout lifted European shares on Thursday, with the FTSEurofirst 300 <
> up 5.4 percent. Japan's benchmark Nikkei < > closed 2.1 percent higher."If these (insurance) guys would fail, it would be much more catastrophic for banks' balance sheets and we would see another round of writedowns," said Edmund Shing, strategist at BNP Paribas in Paris.
Anxiety remained, however, with news of Societe Generale's <SOGN.PA> admission that an "exceptional fraud" by one of its traders would cost the group an estimated 4.9 billion euros ($7.1 billion). The alleged fraud would be one of the biggest in financial history. [
]SocGen also announced plans to raise 5.5 billion euros through a capital increase to shore up its balance sheet. SocGen shares were down 4.1 percent after an earlier trading suspension was lifted.
In foreign exchange trading, the dollar eased 1.0 percent against a basket of six major currencies to 75.635 from a previous session close of 76.401 <.DXY>.
The euro rose 0.8 percent and traded at $1.4753 <EUR=> -- on track for a third straight session of gains -- after European Cental Bank policy-maker Axel Weber said the ECB remains focused on inflation risks, suggesting it is unlikely to follow the Fed's lead and slash euro-zone rates. The euro also rose 1 percent to 157.72 yen <EURJPY=>.
The dollar was up 0.1 percent at 106.90 yen <JPY=>, after earlier slipping to 105.95 yen. Against the Swiss franc, the dollar fell 0.4 percent to 1.0863 <CHF=>.
"They are consistently saying that (euro-zone) growth is OK, there is going to be some effect from a U.S. slowdown, but in their view, they are saying the economy is going to be strong and (inflation) is going to be an issue," said Brian Taylor, head currency trader at M&T Bank in Buffalo, New York.
In the government bond market, U.S. Treasury debt prices were lower. The benchmark 10-year U.S. Treasury note <US10YT=RR> traded down 19/32 in price, with the yield at 3.6739 percent.
The 2-year U.S. Treasury note <US2YT=RR> was down 9/32, with the yield at 2.2847 percent. The 30-year U.S. Treasury bond <US30YT=RR> was down 32/32, with the yield at 4.3712 percent.
European government bonds also fell on Thursday as investors moved into stocks, though yields remained above comparable U.S. debt. The 10-year Bund yield stood at 4.01 percent <EU10YT=RR> while two-year yields were at 3.48 percent <EU2YT=RR>.
At 4 percent, benchmark interest rates in the euro zone are now half a percentage point above U.S. rates, making European debt more attractive to investors than U.S. paper.
