(Adds close of U.S. markets)
By Herbert Lash
NEW YORK, March 13 (Reuters) - Gold shot past $1,000 for the first time and the dollar hit new lows on Thursday as stocks managed a gain in volatile trading amid mixed signs that the subprime housing crisis has reached its nadir.
Equity markets had moved sharply lower earlier amid concern over a looming default on $16.6 billion in debt by an affiliate of buyout firm Carlyle Group.
Later, U.S. stocks rebounded and European shares pared losses after Standard & Poor's said major banks have seen the worst of the housing finance charges and a bailout plan for homeowners gained momentum in Washington. U.S. Treasury prices fell on the news as flight-to-quality investors pulled back on the signs of an abating crisis,
The rebound in U.S. stock prices came as oil, gold and the dollar set new records, all driven outside by speculative buying by a sour outlook on the U.S. economy.
Oil rose to $111 a barrel, the seventh straight record in as many trading days as a weak dollar overshadowed an increase in U.S. crude inventories. U.S. crude <CLc1> settled up 41 cents at $110.33.
Gold futures surged above the historic $1,000 mark, while the dollar plunged below 100 yen for the first time in over a decade as it again hit a new low versus the euro.
"A lot of these markets seem to be linked lately. I'm seeing the dollar strengthen, crude weaken, equities are doing better and bonds are selling off," said Todd Clark, managing director of stock trading at Nollenberger Capital Partners in San Francisco.
Standard & Poor's said some of the subprime-related write-downs are larger than any reasonable estimate of actual losses. But it boosted its previous estimate of write-downs by $20 billion to $285 billion.
"We believe that the largest players, such as Merrill Lynch & Co Inc and Citigroup Inc, have rigorously and conservatively valued their exposures to subprime asset-backed securities such that most of the damage should be behind them," S&P said.
The subprime-related write-downs have taken a major toll on bank balance sheets, sparking a reluctance to extend credit and triggering margin calls and forced selling across markets.
Shares of Merrill Lnych <MER.N>, which had been down almost 3 percent, and Citigroup <C.N>, down as much as 5.5 percent, pared losses to a 1.7 percent decline.
Other financial shares also rose, including heavily battered home mortgage lenders Fannie Mae <FNM.N>, up more than 8 percent, and Freddie Mac <FRE.N>, up more than 5 percent.
The Dow Jones industrial average <
> added 35.09 points, or 0.29 percent, to 12,145.33. The Standard & Poor's 500 Index <.SPX> gained 5.12 points, or 0.39 percent, to 1,313.89. The Nasdaq Composite Index < > rose 13.55 points, or 0.60 percent, to 2,257.42.In the latest fallout, Carlyle Capital Corp <CARC.AS> said late on Wednesday lenders were likely to seize its remaining assets after it defaulted on about $16.6 billion of debt.
"We are in a vicious spiral of unwinding years of increasing leverage in the space of a few weeks," said Andrea Cicione, a credit strategist at BNP Paribas, one of Carlyle Capital's lenders. No one can say how much leverage must be wrung out before the unwinding comes to an end, Cicione said.
In Europe, the FTSEurofirst 300 <
> closed down 1.3 percent at 1,268.46 points, taking losses for the year to 15.8 percent.Banks trimmed intraday losses in excess of 4.5 percent after the S&P report on bank write-downs, but the DJ Stoxx bank index was the leading sectoral loser, falling 2.8 percent.
Earlier in Asia, Japan's Nikkei benchmark <
> sank to a new 2-1/2 year closing low, down 3.3 percent at 12,433.44.Based on the latest available data, the Dow Jones industrial average <
> rose 35.50 points, or 0.29 percent, to end unofficially at 12,145.74. The Standard & Poor's 500 Index <.SPX> was up 6.71 points, or 0.51 percent, at 1,315.48. The Nasdaq Composite Index < > was up 19.74 points, or 0.88 percent, to close unofficially at 2,263.61.The dollar plunged below 100 yen and hit a record low against the euro as worries deepened about a U.S. recession.
The dollar also approached parity with the Swiss franc for the first time ever.
"We are seeing tremendous pressure on the dollar, and if you look at the reasons why the dollar is so unpopular, it's very difficult to see any of those factors changing in the next few months," said Mike Moran, currency strategist at Standard Chartered in New York.
Oil prices extended a rally that has added nearly 30 percent to prices in just over a month, amid all-time weakness in the dollar.
The active U.S. gold contract for April delivery <GCJ8> in New York settled up $13.30, or 1.4 percent, at $993.80 an ounce. It had soared to a record high of $1,001.50.
"I think there is more upside for gold and generally the precious metal complex because the Fed is going to be delivering a very negative real interest rate environment and that is great for gold," said Michael Lewis, global head of commodities research at Deutsche Bank.
U.S. Treasury debt prices retreated rapidly as U.S. stocks recovered.
Stocks rebounded from early losses, pushing benchmark 10-year notes <US30YT=RR>down 30/32 for a yield of 3.55 percent, up 11 basis points. (Reporting by Herbert Lash. Editing by Richard Satran)
