NEW YORK (CNNMoney) -- U.S. stocks were poised to follow global markets higher as central banks in Europe signaled they would provide more cash to help banks deal with the ongoing sovereign debt crisis.
The Dow Jones industrial average (), S&P 500 ( ) and Nasdaq ( ) futures were moderately higher Friday morning. Stock futures indicate the possible direction of the markets when they open at 9:30 a.m. ET.
After markets in Europe closed for trading on Thursday, Bank of England Governor Mervyn King said the central bank and the Chancellor of the Exchequer are working on new policies to provide funding to banks for "several years" at rates below current market rates.
And on Friday, European Central Bank President Mario Draghi said the bank would "continue to supply liquidity to solvent banks where needed." He said strengthening European economies is crucial, and that it's time to implement plans to spur long-term growth.
Still, trading could be volatile Friday, as investors brace for the crucial Greek elections this Sunday.
"In reality, very few are willing to take big positions ahead of the Greek elections and a big week ahead full of policy and leadership meetings," wrote Deutsche Bank analysts Jim Reid and Colin Tan, in a research note.
The concern is that anti-austerity political parties in Greece will win enough seats in parliament to derail the bailout program secured earlier this year. This, in turn, could lead to Greece exiting the euro.
Last week, Spain asked for €100 billion from the European Union to provide a buffer for its ailing banks. But the country was hit by a downgrade by rating agency Fitch last week and Moody's on Wednesday. Both agencies warned the country's debt is at risk for further downgrade into junk bond status.
The yields on Spanish 10-year bonds improved slightly Friday, falling to 6.83% from the high just above 7% early Thursday.
In the United States, reports are due Friday on manufacturing, industrial production and consumer sentiment.
The phenomenon known as quadruple witching is also occurring on Friday. That's when the contracts for stock futures and options, as well as stock options and single stock futures, all expire.
