(Recasts with U.S. markets, adds byline; dateline previous LONDON)

NEW YORK, March 7 (Reuters) - Federal Reserve efforts to ease tight credit markets did little to calm frayed investor nerves on Friday, as stocks in Europe and the United States fell to six-week lows while oil climbed to new highs.
The markets got a fresh jolt of recession worries when the U.S. Labor Department reported the biggest drop in U.S. nonfarm payrolls in nearly five years. A Fed move to add liquidity through a $200 billion injection of cash to the banking system helped a recovery rally but the market sagged as the session wore on.
Gold, which neared $1,000 this week for the first time, steadied in late European trade after rising more than 1 percent after the dollar hit record lows early in the day and then recovered .
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 numbers today push us that much closer to a full-blown recession and perhaps inflation expectations as a result of that have come down a little bit," said Stephen Stanley, chief economist with RBS Greenwich Capital Markets in Greenwich, Connecticut.
"The steps that the Fed took this morning have provided a backstop liquidity-wise to the market," Stanley said.
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 Wall Street.
Energy companies also felt the pinch from economic concerns, even as oil set 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 <
> was down 113.97 points, or 0.95 percent, at 11,926.42. The S&P 500 <.SPX> was down 9.29 points, or 0.71 percent, at 1,295.05. The Nasdaq Composite Index < > was down 8.51 points, or 0.38 percent, at 2,211.99.Struggling bond insurers also were in the spotlight. Shares of Ambac Financial Group Inc <ABK.N> fell 5.9 percent to $6.98 after it sold $1.5 billion of shares and convertibles to protect the company's credit ratings. Investors who wanted the company to raise more were disappointed that a strategic buyer did not appear to bail out Ambac with a fund injection.
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.
Profit fell in half in the fourth quarter after a 1.5 billion euro ($2.3 billion) subprime write-down. But Fortis, without providing further details, said it was in talks on a deal that would boost its solvency.
Swiss wealth manager EFG International took a hit from the credit crisis and its shares fell sharply after it reported a fund of U.S. municipal bonds it was distributing had to be liquidated, causing losses for investors.
EFG shares fell 6.38 8 percent at 34.50 Swiss francs, after plunging 18 percent earlier in the day.
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 dollar rebounded from record lows it hit as dropped on the surprise contraction in U.S. payrolls.
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 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 73.055.
Gold steadied as platinum and palladium pared losses after falling sharply on expectations that South African power problems might improve in the coming weeks, analysts said.
Gold <XAU=> rose as high as $988 an ounce after the data but fell to $976.00/976.80 at 1523 GMT, against $976.20/976.95 late in New York on Thursday, when it hit a record high of $991.90.
"Compared with what it has done before, gold has slightly underperformed in the last week," said Stephen Briggs, economist at SG Corporate and Investment Banking.
"There is a huge uncertainty in the market after these massive gains we have seen this year. People are getting a bit nervous of the logic of such high prices in an environment of the U.S. remorselessly heading into a recession."
Oil rallied to new highs. Crude futures had earlier dropped sharply after a weak jobs report, suggesting demand may decline. But geopolitical tensions and supply concerns after U.S. inventories fell last week also supported crude.
April crude <CLJ8> in New York jumped to a new record of $106.54, up from $103.91 and eclipsing Thursday's $105.97 peak.
Bonds were little changed as the weak economy news vyed with the Fed's credit bolstering action for investor attention. The benchmark 10-year note <US10YT=RR> slipped 3/32 in price for a yield of 3.61 percent, up from 3.59 percent late Thursday. The 10-year yield fell to the lowest since late January immediately after the payrolls data, at about 3.49 percent.
