NEW YORK (CNNMoney) -- U.S. stocks were set to decline at the open Friday as investors grew concerned about the latest obstacle in Greece's ongoing debt saga.
The Dow Jones industrial average (), S&P 500 ( ) and Nasdaq ( ) futures were down between 0.7% and 0.9%. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
The fresh bout of worries came after eurozone finance ministers said that the new Greek austerity deal does not go far enough. The finance ministers said they would need to see more spending cuts before signing off on a new €130 billion bailout, which is key to the debt-laden country making its payment on a €14.5 billion bond redemption next month and avoiding default.
"Despite the important progress achieved over the last days, we did not yet have all necessary elements on the table to take decisions today," said Jean-Claude Juncker, the prime minister of Luxembourg and head of the Eurogroup.
Specifically, Juncker said the reform package needs to be approved by the Greek parliament this weekend, and Greece's leaders need to pledge they'll continue to implement the measures after elections in April. He also said that Greece must cut an additional €325 million from its "structural expenditures" in 2012.
If Greece meets those conditions, a bailout package could be signed as early as next week, when eurozone finance ministers are due to meet again.
Meanwhile, Greece is also working to finalize a deal with its private-sector creditors to write down a portion of its debt.
