(Adds close of U.S. markets)
By Herbert Lash
NEW YORK, March 7 (Reuters) - Federal Reserve efforts to loosen up tight lending markets did little to calm frayed investor nerves on Friday, as global stocks stayed on a downward track amid fears credit problems are deepening.
Equities declined from the start of the New York session on recession fears sparked by a U.S. Labor Department report showing the biggest drop in U.S. non-farm payrolls in nearly five years. The Fed move to inject $200 billion of cash into the banking system sparked a short-lived stock rally.
Gold erased initial gains to finish lower amid talk that cash-squeezed funds sold bullion for liquidity, capping a volatile week which saw gold made several runs toward $1,000 an ounce.
Oil in New York and London rallied to record highs, lifted by technical buying as the weak dollar kept funds flowing into inflation hedges like crude futures.
While Fed efforts to ease credit markets may succeed, the second consecutive monthly decline in payrolls suggested the U.S. central bank will have to continue to aggressively cut its benchmark interest rate to bolster the economy.
The jobs data, higher oil and credit crisis roiling the financial system all cast a long shadow on markets.
"We have a long way to go until the economy is back up and running at full-tilt. You're looking for a silver lining and you just can't find it," said Edward Bretschger, director of equity sales and trading at Calyon Securities in New York.
Big industrial companies seen as economic bellwethers such as heavy-equipment maker Caterpillar <CAT.N> and conglomerate General Electric <GE.N> were among the biggest drags on stocks.
Energy companies also felt the pinch of slower growth concerns, even with oil setting a record high. Exxon Mobil <XOM.N> and Chevron <CVX.N> weighed on the benchmark Standard & Poor's 500 Index and the Dow Jones industrial average.
The Dow industrials <
> ended below 12,000, a technical break-point that has closed blow that level only once before in the past 16 months. The Standard & Poor's 500 <.SPX> closed below 1,300 for the first time since September 2006.Companies linked to the meltdown in mortgage-backed securities found a difficult time raising cash.
Bond insurer Ambac Financial Group Inc <ABK.N> sold $1.5 billion of shares and convertible debt at fire-sale prices to protect it from rating downgrades, but not satisfying some analysts who wanted the company to raise more capital.
Another mortgage concern under pressure, Thornburg Mortgage Inc <TMA.N> on said its survival is at stake after it was unable to meet $610 million of margin calls.
European shares hit their lowest close in more than six weeks after data showed the U.S. labor market was struggling, but a rebound in U.S. stocks helped pare losses.
The FTSEurofirst 300 <
> index of top European shares closed down 1.1 percent at 1,269.42 points, its lowest close since Jan. 23. Earlier, the index fell to 1,258.27.Dutch-Belgian concern Fortis became the latest among the world's biggest financial groups to post losses from exposure to subprime-related debt.
MSCI's main world stock index <.MIWD00000PUS>, a benchmark for many professional investors, lost 1.3 percent while its emerging market counterpart <.MSCIEF> sank 2.3 percent.
The euro surged to $1.5459 <EUR=>, according to Reuters data, as investors took fright at news that U.S. payrolls shrunk again in February.
The euro later traded around $1.5345, down 0.3 percent on the day as investors considered the outlook on U.S. interest rates.
The New York Board of Trade's dollar index, which tracks the dollar's performance against the basket of currencies, slumped to an all-time low of 72.462 <.DXY>. It later rebounded to around 73.039.
Gold eased as platinum and palladium pulled back sharply on U.S. recession fears in a broad-based commodities sell-off.
"Gold is having trouble here, as it bounced off the $990 area again. It was up sharply but ended lower at the end. To me, it's very negative sign," said Leonard Kaplan, president of Prospector Asset Management at Evanston, Illinois.
"It seems like people are getting out of everything because the hedge funds that are long gold are having troubles in other areas and they need to sell to raise cash," Kaplan said.
Gold <XAU=> rose as high as $988 an ounce in morning trade but was at $972.60/973.40 by New York's last quote at 2:15 p.m. EST (1915 GMT), against $976.20/976.95 late in New York on Thursday, when it hit a record high of $991.90.
Oil prices eased off a new record after buying by speculators hedging against the weaker dollar and inflation sent prices above $106 a barrel.
U.S. oil <CLc1> settled down 32 cents at $105.15 a barrel, trimming gains after hitting an all-time high of $106.54 earlier in the trading session. London Brent <LCOc1> crude settled 23 cents lower at $102.38 a barrel.
