NEW YORK, June 4 (Reuters) - A dour U.S. jobs report coupled with fears over European banks and talk of a "Greek-style" debt crisis in Hungary drove down global stocks and sent the euro to a four-year low on Friday.
Safe-haven investments such as gold and government debt rose while oil and other commodities extended losses after the U.S. Labor Department said nonfarm payrolls in May rose by 431,000, far below a consensus estimate for 513,000 new jobs.
Although payrolls last month grew at their fastest pace in 10 years, buoyed by temporary hiring for the decennial census, private hirings slowed sharply as businesses opted to increase hours rather than take on new workers.
"The market is bothered by the fact that you had a smaller headline gain in private payrolls, and very little of it was in the services sector," said Cary Leahey, senior managing director at Decision Economics in New York.
European stocks were already in negative territory before the jobs report as concerns about derivatives operations of French bank Societe Generale <SOGN.PA> weighed on banks and fears about Hungary's debt situation soured market sentiment.
MSCI's all-country world equity index <.MIWD00000PUS> fell 1.6 percent.
The Dow Jones industrial average <
> fell 164.60 points, or 1.61 percent, to 10,090.68, while the Standard & Poor's 500 Index <.SPX> lost 15.73 points, or 1.43 percent, to 1,087.10. The Nasdaq Composite Index < > was down 27.96 points, or 1.21 percent, at 2,275.07.In Europe, the FTSEurofirst 300 <
> index of top shares was down 1.5 percent, led lower by banking stocks. Shares of SocGen slumped more than 7 percent on the derivatives concerns. A bank spokesman said there was nothing to be said about the matter. [ ]Emerging market stocks were 0.9 percent lower according to a MSCI index <.MSCIEF>.
"There is fear coming back into the market," said Matthew Brown, sales trader at ETX Capital in London. "There are unsubstantiated rumors of a French bank having derivative losses and there are also comments coming out of Hungary."
Investors were spooked again by comments out of Hungary, perceived as the weak link in eastern Europe due to high debt ratios.
A spokesman for Hungary's prime minister said a leader of the newly-elected ruling party had not exaggerated when he had said on Thursday Hungary may face a Greek-style debt crisis.
The forint currency fell to a one-year low and pressured shares of European banks with exposure to Eastern Europe.
EURO FURTHER PRESSURED
The euro <EUR=> weakened 0.79 percent to $1.2061, also pressured by comments by French Prime Minister Fracois Fillon, who said he only saw "good news" in the parity between the European single currency and the dollar. [
]Fillon's remarks were later clarified by a source, who said his reference to "parity" was about the general evolution of the exchange rate between the euro and the dollar. [
]The euro traded as low as $1.2019, according to Reuters data.
The dollar also rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.64 percent. Against the Japanese yen, however, the dollar <JPY=> was down 0.65 percent at 92.05.
Investors rushed into assets considered safer after the jobs data, pushing 10-year Treasury notes <US10YT=RR> up 27/32 in price. Yields on the benchmark bond fell to 3.268 percent from 3.37 percent on Thursday.
Spot gold <XAU=> trimmed losses, still trading 0.31 percent lower at $1,203.80 an ounce, after touching a session low of $1,196.65 an ounce.
Assets seen as higher risk fell. Copper fell to near a five-month low, and U.S. crude oil futures fell 1.59 percent to $73.42 per barrel. (Editing by Leslie Adler)
