(Adds close of U.S. markets)
By Herbert Lash
NEW YORK, March 10 (Reuters) - A new wave of credit fears swamped Wall Street on Monday, pushing stocks to 17-month lows and bond prices sharply higher, as skittish investors reacted to rumors and news of firms exposed to the mortgage crisis.
A sell-off in financial stocks accelerated around midday amid talk -- later strongly denied -- that Bear Stearns faced liquidity issues. The cost to insure debt of the brokerage icon surged, and its shares plunged more than 11 percent.
U.S. Treasury debt prices jumped and interest rate swap spreads gapped wider on the speculation, just one more sign of how markets have tightened amid a growing list of troubles that have jolted financial sector.
Oil shot to a record over $108 a barrel as investors bought crude contracts as a hedge against a depressed dollar, which tumbled against the yen amid fears of a U.S. recession.
Recession fears mounted on Friday's report of the biggest U.S. job losses in five years and strains in the credit market have sunk the dollar and raised expectations the Federal Reserve could soon cut interest rates again to prop up the economy.
News about the depth of the mortgage-sparked credit crisis remained bearish.
Private equity and real estate company Blackstone Group LP said challenging business conditions and a write-down of bond insurer FGIC led to a huge fourth-quarter slump in earnings.
Citigroup forecast U.S. investment banks would suffer about $9 billion of write-downs in the first quarter, driven by more leveraged loan and mortgage-related losses.
And the head of Japan's financial regulator said global financial losses from the crisis have totaled $215 billion, with a little more than half coming from the United States.
The blue-chip Dow Jones industrial average closed down to lows last seen in October 2006, and the benchmark Standard & Poor's 500 Index closed to August 2006 lows.
Based on the latest available data, the Dow Jones industrial average <
> fell 153.54 points, or 1.29 percent, to end unofficially at 11,740.15. The Standard & Poor's 500 Index <.SPX> was down 19.98 points, or 1.54 percent, to finish unofficially at 1,273.39. The Nasdaq Composite Index < > was down 43.15 points, or 1.95 percent, to close unofficially at 2,169.34.Bear Stearns Cos <BSC.N> and its former chief executive denied market speculation that the investment bank faced a cash crunch, helping pare losses after its shares had fallen to a five-year low, though the stock remained depressed, closing down 11 percent at $62.30.
Increased worries that a credit crisis would lead to more bank losses and cast a longer economic shadow also hit European shares, which fell to their lowest close since mid-2006.
The FTSEurofirst 300 <
> index of top European shares ended 1.15 percent lower at 1,254.76 points. Mining shares took the most points off the index, followed by banking shares.The top three negative weights on the index were mining stocks Rio Tinto <RIO.L>, BHP Billiton <BLT.L> and Anglo American <AAL.L>, which fell between 4 and 6 percent, driven by a fall in copper prices.
UBS <UBSN.VX> fell 4 percent, BNP Paribas <BNPP.PA> 2.4 percent and Credit Suisse <CSGN.VX> 3.2 percent.
"People are concerned at signs that the financial system is not repairing itself, and that earnings outside the financial sector are now going to get hurt," said John Haynes, strategist at Rensburg Sheppard Investment Management.
"Interest rate cuts are not enough -- this is beginning to go beyond the Fed," he said.
MSCI's main gauge of world shares <.MIWD00000PUS>, a benchmark for many professional investors, was down 0.3 percent for a more than 11 percent loss since the beginning of the year.
Earlier, Japan's Nikkei finished down 250.67 points or 2 percent at 12,532.13, its lowest since Sept. 1, 2005. The broader TOPIX <
> closed down 1.9 percent at 1,224.39.U.S. Treasury debt prices extended gains, pushing yields on the benchmark 10-year note down to about 3.45 percent, and Euro-zone government bond futures jumped to their highest level in 15 months on the rumors concerning Bear Stearns.
A government employment report on Friday that showed a second straight month of job losses led Goldman Sachs to change its view on monetary policy and say the Federal Reserve may cut interest rates ahead of a policy-setting meeting on March 18.
The Fed will cut the benchmark federal funds rate to 2 percent by late April from a current 3 percent, most likely in half-percentage point steps at the next two meetings, it said.
The February jobs report last week leaves little doubt that the U.S. economy is in recession, Goldman said.
Oil extended a rally led by investors seeking a hedge against the tumbling dollar and inflation.
U.S. crude <CLc1> settled up $2.75 at $107.90 a barrel, off a record $108.21 hit earlier in the session. London Brent crude <LCOc1> jumped $1.78 to settle at $104.16 a barrel.
Speculators have rushed into commodities to hedge against the weaker dollar as well as prospects that further Fed rate cuts could fuel inflation, helping to lift oil to average over $95 so far this year despite signs the faltering U.S. economy is crimping energy demand.
"It's the same thing that has been going on, it's a shark-like feeding frenzy on commodities. A lot of people feel the latest numbers on employment were bearish on the economy," said Peter Beutel, president of Cameron Hanover.
"The bottom line is people believe that as long as we see bearish numbers it will lead to another Fed cut."
The dollar tumbled against the yen on Monday as fears of a U.S. recession hit stock prices. [
]Gold turned initial losses to end higher, as record high oil prices and a weaker dollar prompted speculative buying a broad-based precious metals recovery.
Spot gold <XAU=> fell as low as $961.00 an ounce and was at $974.10/974.90 at 2:15 p.m. EDT (1815 GMT), against $972.60/973.40 late in New York on Friday.
Gold is generally seen as a hedge against oil-led inflation. (Reporting by Kristina Cooke Pedro Nicolaci da Costa, Steven C. Johnson and Atul Prakash in London. Editing by Richard Satran) (Writing by Herbert Lash)
