NEW YORK (CNNMoney) -- U.S. stocks were headed for a lower open Thursday as fears about a global economic slowdown resurfaced.
Investors are worried that European leaders won't be able to make good on their most recent pledge to get a permanent bailout fund in place. And Wednesday's Fed minutes, which showed the central bank was wary of announcing any new stimulus measures anytime soon, is adding to the pessimism.
"The central banks are running out of options," said Mark Helweg, president of financial software company MicroQuant. "Where will we go from here? Negative interest rates?"
The Dow Jones industrial average (), S&P 500 ( ) and Nasdaq ( ) futures were down about 0.7% early Thursday. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
Concerns about the eurozone bailout fund, the European Stability Mechanism, weighed on European stocks. Implementation of the fund won't be quick, and a German high court's decision about whether that country's involvement violates its laws may not happen for months.
The initial euphoria from the recent European summit has faded, according to Gerry Davies, a ForexLive currency analyst in London.
"All that excitement has effectively evaporated," Davies said.
The euro fell below $1.22 to a fresh two-year low against the dollar. And the selling spilled over to commodities, with oil prices sliding more than 1%.
U.S. stocks closed lower Wednesday for the fourth day in a row.
