NEW YORK, March 24 (Reuters) - U.S. stocks jumped sharply and bonds fell on Monday as JP Morgan moved to complete a sharply higher bid for troubled investment bank Bear Stearns, easing nervous investors' fears about a global credit crisis.
The dollar firmed and bond prices fell on the Bear bid and also on a sign that a U.S. housing recovery may finally be underway, with a report that existing sales moved higher in February.
Oil slipped amid a recovery in the U.S. dollar and lingering worries over slowing energy demand.
Trading volume was thin as financial markets in Europe and parts of Asia remained closed after the Easter weekend.
But a crisis that has gripped financial markets for months remained the center of attention. In a move to appease disgruntled shareholders JPMorgan Chase & Co <JPM.N> raised its all-stock offer for Bear Stearns Cos <BSC.N> to about $10 a share, compared with $2 last week.
In Europe, British Prime Minister Gordon Brown and French President Nicolas Sarkozy will urge banks this week to make "full and immediate disclosure" of write-offs due to the global credit crisis, British officials said on Monday.
Uncertainty over the scale of bad debts on banks' books, which some estimates put as high as $600 billion, has sapped investor confidence and pushed many stock indexes around the world into bear territory.
Bear Stearns, which had been ranked the No. 5 U.S. investment bank, collapsed amid large subprime mortgage losses and fading investor confidence prompted a run on the bank.
"Clearly, this increases the chance the deal goes through," said James Ellman, a portfolio manager with Seacliff Capital. "But there are still going to be employees and shareholders unhappy with $10 a share."
Major U.S. stock indexes rose, led by financial shares, which gained about 2.5 percent, according to the Standard & Poor's index of financial stocks <.GSPF>.
Bear Stearns shares surged 80 percent to $11.52 on the news, while JPMorgan shares gained 3.6 percent to $47.64.
Tthe Dow Jones industrial average <
> rose 234.70 points, or 1.90 percent, to 12,596.02. The Standard & Poor's 500 Index <.SPX> gained 26.49 points, or 1.99 percent, to 1,356.00 and the Nasdaq Composite Index < > rose 70.83 points, or 3.13 percentThe dollar rallied across the board and climbed to session highs versus the yen, boosted as U.S. Treasury prices yields climbed after the surprising U.S. existing home sales.
The euro fell 0.3 percent against the dollar to $1.5380 <EUR=>, from $1.5420 just before. Against the yen, the dollar jumped to the day's highs at 100.79 yen <JPY=>, well off a nearly 13-year low of 95.77 yen posted last week.
The dollar index, a measure of the greenback's value against six major currencies, was up 0.4 percent at 73.039<.DXY>. It earlier rose 73.194.
"The housing sector and mortgages are at the center of problems in the financial sector. Any good news in housing at the margin would be very helpful at this point for the dollar," said Ken Landon, global currency strategist at JPMorgan Chase in New York.
While the pace of existing homes was better than consensus estimates, a bottom in the beleaguered U.S. housing market is too early call, many analysts said.
Existing home sales rose to a 5.03 million-unit annual rate in February but median home prices fell 8.2 percent, the sharpest drop since the National Association of Realtors began keeping records in 1968.
"Selling more homes cheaper -- too early to call that a bottom," said Ian Lyngen, interest rate strategist at RBS Greenwich Capital in Greenwich, Connecticut.
It will be hard to work off the housing inventory with deteriorating labor markets and high consumer debt levels, said Josh Stiles, managing director and bond strategist at IDEAglobal in New York.
"We don't believe that the housing market has bottomed and we don't believe that the last bad news about financial stress is behind us either, but Treasuries were overdue for a correction," Stiles said.
U.S. Treasury debt prices fell as a stock market rally and positive developments on the housing and credit front weakened the bid for safe-haven U.S. government debt.
Two-year Treasury notes fell 12/32 in price, their yields <US2YT=RR> rising to 1.81 percent, from 1.61 percent on Thursday.
The benchmark 10-year Treasury note's price, which moves inversely to its yield, was down 1-12/32, its yield <US10YT=RR> rising to 3.51 percent from 3.34 percent on Thursday.
U.S. short-term interest rate futures also fell sharply.
The implied prospects for the Federal Reserve to cut a key lending rate by half a percentage point in April fell to 22 percent from 56 percent last week. A 25 basis point rate cut, to 2 percent, is still fully priced.
Oil prices fell moderately, extending last week's sharp declines. U.S. crude futures <CLc1> fell 22 cents to $101.62 a barrel after falling more than $1 earlier -- bringing them more than $10 below last Monday's $111.80 peak.
Brent crude <LCOc1> was up 30 cents to $100.68.
Asian shares rose in holiday-thinned trade on Monday, led by a 4 percent gain for Taiwan after an opposition win in the presidential election boosted expectations for better trade ties and less political tension with China.
Taiwan markets surged the first trading day after a victory by Ma Ying-jeou of the more China-friendly Nationalist Party, or Kuomintang (KMT), boosting hopes for a greater flow of tourists, trade and capital between Taiwan and China.
Taiwan's main TAIEX <
> jumped more than 6 percent at the open -- its biggest one-day percentage gain in more than seven years -- before easing back to a gain of 4 percent.The Taiwan dollar <TWD=TP> also jumped to a 10-year high of T$30.218 against the dollar.
Activity was subdued in Asia as markets in many parts of the region were closed for the Easter holiday.
MSCI's index of shares outside Japan <.MSCIAPJ> rose 1.3 percent, although it is still down 18 percent so far this year.
Tokyo's Nikkei index <
> traded in and out of the red to end the session flat. Investors were braced for the upcoming corporate results season. (Reporting by Herbert Lash. Editing by Richard Satran)
