NEW YORK/LONDON, June 4 (Reuters) - A dour U.S. jobs report added to fresh fears on Friday over European banks and talk of a "Greek-style" debt crisis in Hungary, pushing global stocks lower and the euro to a new four-year trough to the dollar.
Safe-haven investments like gold and government debt rose while commodities and European shares extended losses after the U.S. Labor Department said non-farm payrolls in May rose by 431,000, far less than a consensus estimate of 513,000.
While 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 sign on new workers.
German bund futures <FGBLc1> hit a new session high, rising to as high as 129.48 compared with 128.99 before the jobs data. The yield on the two-year Schatz fell to 0.468 percent from 0.488 percent. For details see: [
]Benchmark 10-year Treasury notes <US10YT=RR> traded up 28/32 in price at 101-30/33, compared with being 10/32 higher shortly before the employment data.
MSCI's all-country world equity index <.MIWD00000PUS> fell 0.8 percent.
The pan-European FTSEurofirst 300 <
> index of top shares was down 1.5 percent at 1,001.31 points, led by banking stocks."The initial take is this is a pretty bad number; well below expectations," T.J. Marta, founder and market strategist with Marta on the Markets in Scotch Plains, New Jersey:
"The key disappointment was in the private payrolls. While we did get the census hiring, the private economy is not hiring the way we would have liked."
Spot gold <XAU=> turned higher, reaching $1,208.75 an ounce, after the payrolls data missed expectations.
Assets seen as higher risk fell. Copper fell to near a 5-month low and U.S. crude oil futures fell almost $2 to below $73 a barrel.
U.S. stock index futures also extended losses. S&P 500 futures <SPc1> fell 26.4 points and were below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.
Dow Jones industrial average futures <DJc1> slumped 191 points, and Nasdaq 100 futures <NDc1> lost 45 points.
The dollar fell versus the Japanese yen, while the euro extended losses, down more than 1 percent at a session low of $1.2019 <EUR=>, according to Reuters data.
The euro hit a record low versus Swiss franc.
European stocks were hurt by concern over the derivatives division of French Societe Generale.
Societe Generale, which declined to comment on speculation about losses in its derivatives division, fell 6.3 percent.
Investors earlier had been spooked again by comments out of Hungary, perceived as the weak link in eastern Europe due to high debt ratios.
A spokesman for the 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.
That pushed the forint currency to a one-year low and hit shares in European banks exposed to eastern Europe.
"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." (Reporting by Herbert Lash)
