NEW YORK, Sept 25 (Reuters) - Risk appetite returned to financial markets on Thursday as growing hopes the U.S. Congress is close to approving a $700 billion bailout lifted global stocks and cut the appeal of safe-haven gold and government debt.
European and U.S. stocks rose more than 2 percent on hopes the bailout will avert a wider financial crisis and deep slide in world economic growth.
U.S. and euro zone government debt prices fell, as traders reversed a recent dash for safety on growing optimism the bailout of troubled banks is closer to passage, despite a fresh spate of gloomy U.S. economic data and news.
But in currency markets the U.S. dollar fell against the euro on lingering nervousness over the effectiveness of the bailout plan and the disappointing economic news.
The dollar's weakness and optimism over the bailout plan lifted oil prices more than $2 a barrel in New York.
In equity markets, banking shares jumped on both sides of the Atlantic as investors bet that the financial sector bailout could help thaw credit markets and revive lending.
"I certainly think that Congress will pass something and that will help for a little while. It gives us some time to unwind some of the positions and see where we stand when the smoke clears," said Warren Simpson, managing director at Stephens Capital Management in Little Rock, Arkansas.
Hopes for the bailout's approval gained momentum after U.S. President George W. Bush said in a national broadcast Wednesday evening that the United States was in a serious financial crisis.
U.S. Sen. Christopher Dodd, chairman of the Senate Banking Committee, on on Thursday said Democrats and Republicans had reached a "fundamental agreement" on the principles for a bailout bill.
Before 1 p.m., the Dow Jones industrial average <
> was up 246.75 points, or 2.28 percent, at 11,071.92. The Standard & Poor's 500 Index <.SPX> was up 29.18 points, or 2.46 percent, at 1,215.05. The Nasdaq Composite Index < > was up 44.83 points, or 2.08 percent, at 2,200.51.Shares of JPMorgan Chase <JPM.N> , the No. 3 U.S. bank, rose 7.4 percent, and Bank of American <BAC.N> advanced 5.35 percent.
Companies seen as economic bellwethers, such as IBM <IBM.N> and Caterpillar <CAT.N>, rallied on hopes the rescue package could spur a pick-up in consumer and business spending. IBM gained 2.5 percent and Caterpillar rose 1.3 percent.
European stocks ended sharply higher, rising for the first time in four sessions as renewed optimism over the U.S. rescue plan eclipsed weak economic data and a profit warning by General Electric <GE.N>.
The FTSEurofirst 300 <
> index of top European shares closed 2.16 percent higher at 1,125.43 points.Among banking stocks, Credit Agricole <CAGR.PA> gained 6.5 percent and Royal Bank of Scotland <RBS.L> added 5 percent.
But the safe-haven appeal of government debt did not fully disappear, given worries about the long-term effectiveness of the bailout program to thaw seized-up credit markets.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 15/32 to yield 3.88 percent. The 30-year U.S. Treasury bond <US30YT=RR> fell 15/32 to yield 4.44 percent.
"There continues to be uncertainty. That means flight-to-safety bids for Treasuries will remain," said Michael Pond, Treasury strategist at Barclays Capital in New York.
Low bond yields, a huge spike in stock market volatility and the premium for borrowing dollars over anticipated official policy rates, known as Overnight Index Swaps, remained high.
"That is all indicating a very high level of risk aversion," said Arthur van Slooten, strategist at Societe Generale.
The Libor/OIS spread blew out to 200 basis points, up from about 80 basis points at the start of September, while the cost of borrowing euros and sterling also jumped.
Other signs of stress among banks, such as the premium paid for three-month euro-dollar deposits over Treasury bill yields, known as the TED spread, were also near historic highs.
The wide spreads reflect the extent to which banks are hoarding cash and are loath to lend as they await a resolution of the U.S. proposal to take troubled assets off banks' books.
Currency trading was choppy as worries remained about when Congress would approve the plan and how successful the deal would be in tackling the crisis.
"It's been a real roller-coaster ride," Todd Elmer, a currency strategist at Citigroup in New York.
The euro <EUR=> rose 0.15 percent at $1.4633, and against the yen the dollar <JPY=> fell 0.34 percent at 106.62.
The dollar rose slightly against major currencies, with the U.S. Dollar Index <.DXY> up 0.01 percent 76.995.
U.S. light sweet crude oil <CLc1> rose $2.45 to $108.18 a barrel.
Spot gold prices <XAU=> fell $9.15 to $871.45 an ounce.
Stocks mostly fell overnight in Asia, pressured by doubts about the bailout and fears over the economic fallout still to come from the crisis.
The MSCI index of Asia-Pacific stocks outside of Japan <.MIAPJ0000PUS> fell 0.62 percent by 1500 GMT. Japanese shares also lost ground, with the Nikkei average <
