* U.S. stocks in late rally on hopes of bailout approval

* Oil slips amid financial market turmoil
* Gold climbs 4 pct as jittery investors seek safe havens (Adds close of U.S. markets)

NEW YORK, Sept 26 (Reuters) - Hopes the U.S. Congress will approve plans to bail out the troubled financial sector lifted the Dow in a late rally on Friday and left other stocks little changed, but the lack of a deal spurred demand for safe-havens.
Gold jumped 4 percent at one point and the yen climbed broadly as investors piled into safer assets after news the bailout talks had stalled and the failure of Washington Mutual, the biggest bank closure in U.S. history, eroded confidence.
Investors flocked to cash and U.S. and euro-zone government debt but a late rally in the shares of the biggest U.S. banks reflected optimism lawmakers would hammer out a deal on the bailout over the weekend tempered the flight for safety. U.S. government debt pared gains, momentarily losing their safe-haven bid, in late trade after stocks rallied.
"Wall Street is banking on a definitive agreement in place before markets open on Monday," said Fred Dickson, director of retail research at D.A. Davidson & Co in Lake Oswego, Oregon.
The late stock rally, which sent the Dow up more than 100 points, was led by big banks amid the ongoing tectonic shifts in the financial landscape.
Shares of JPMorgan Chase & Co <JPM.N> jumped more than 10 percent after the bank capped its purchase of Washington Mutual by selling $10 billion of stock -- 20 percent more than it had said it wanted to raise.
And just before Wall Street trading closed came news that Wachovia Corp <WB.N>, the No. 6 U.S. bank, was in early talks with Citigroup, but no deal may emerge, The New York Times reported, citing people familiar with the matter.
Meanwhile, jitters over the bailout and the economy were not fully overcome. Interest rate futures showed investors were betting the Federal Reserve may slash key interest rates by as much as half a percentage point from the current 2 percent by year-end.
In another sign of risk aversion, investors sold high-yielding currencies such as the Australian dollar and dumped stocks elsewhere in the world.
Central banks injected fresh liquidity into the global banking system, helping lower soaring inter-bank borrowing rates, but money markets remained mostly paralyzed.
"There is risk aversion at the moment and there is a huge amount of uncertainty and that's why we're seeing gold rally and the yen being the strongest performer across the board," said Shaun Osborne, chief currency strategist at TD Securities in Toronto.
European equity markets again fell sharply while U.S. stocks were lower most of the session. Oil prices and the U.S. dollar slipped, another sign of widespread uncertainty.
Market jitters again hit Belgian-Dutch bank Fortis <FOR.AS><FOR.BR> even after it denied it was facing a liquidity crisis. Fortis said it has a funding base of 300 billion euros and solid solvency ratios, but its shares plunged 20 percent to a 15-year low.
"So severe is the crisis of confidence that any bank that has funding or leverage issues, quite apart from the quality of assets, is unnaturally vulnerable in the current environment," said NCB Stockbrokers strategist Bernard McAlinden in Dublin.
The collapse of Washington Mutual <WM.N>, the largest U.S. thrift, fueled concerns about the potential fallout of the credit crisis. Fresh data on second-quarter U.S. gross domestic product that revised downward the government's prior growth estimate also pointed to economic woes ahead.
But strong gains in the shares of JPMorgan, Bank of America, Citigroup and Wells Fargo led the late rally on Wall Street.
The Dow Jones industrial average <
> closed up 121.07 points, or 1.1 percent, at 11,143.13. The Standard & Poor's 500 Index <.SPX> rose 4.09 points, or 0.34 percent, at 1,213.27. The Nasdaq Composite Index < > fell 3.23 points, or 0.15 percent, at 2,183.34.Bank of America rose 6.8 percent, while Citigroup gained 3.8 percent, and Wells Fargo <WFC.N> rose 9.4 percent.
Wachovia was among financial shares taking a knock, falling 27 percent on worries about heavy mortgage losses. Another large U.S. bank, National City Corp <NCC.N>, shed 26 percent on same concerns.
Technology shares took a heavy blow after Research In Motion <RIM.TO><RIMM.O>, the BlackBerry maker and a tech bellwether, warned that quarterly profit will fall short of Wall Street's forecasts. Its shares slid 27.5 percent.
The U.S. economy grew less strongly than previously thought in the second quarter as consumers boosted spending less vigorously and businesses trimmed some investments, a sign of a dimmer outlook even before the financial crisis deepened.
The FTSEurofirst 300 index <
> of top European shares ended down 1.8 percent at 1,104.79 points, with banks taking the most points off the index. The pan-European index fell 4 percent for the week, and is off nearly 27 percent so far this year. Miners tracked metal prices sharply lower.Government debt prices fell.
Government debt prices rose after having fallen for most of the session. The price of two-year Treasury notes <US2YT=RR> rose 8/32 to yield 2.04 percent, and the benchmark 10-year U.S. Treasury note <US10YT=RR> gained 4/32 to yield 3.85 percent.
The dollar was mostly lower. Against the yen, the dollar <JPY=> fell 0.24 percent at 106.15, and the euro <EUR=> rose 0.08 percent at $1.461.
The yen has gained 1.6 percent against the dollar so far this week and about 3 percent this month amid heightened pressure in financial markets.
Oil also fell, pressured by concerns over the financial market crisis. Further pressure came as investors, who flocked into oil and other commodities earlier this year as a hedge against inflation and a weak dollar, shift into safer havens.
U.S. crude <CLc1> settled at $106.89 a barrel, down $1.13, trading between $104.25 and $108.11.
London Brent crude <LCOc1> settled at $103.54, down $1.06.
Spot gold prices <XAU=> rose $10.50 to $886.20 an ounce.
"The main driver right now is the dollar, but also risk aversion," said analyst Barbara Lambrecht at Commerzbank in Germany.
Asian stocks overnight fell. Japan's Nikkei share average <
> shed 0.9 percent, and the MSCI index of Asia-Pacific stocks outside Japan <.MIAPJ0000PUS> fell 1.7 percent.
