The European Central Bank (ECB) has "stepped up" its preparations for further asset purchases, central bank President Mario Draghi said at his his regular news conference on Thursday.
Draghi said ECB policymakers would review measures next year and that this could include changing the "size, pace and composition" of its asset-purchasing programs.
"We don't need unanimity for QE (quantitative easing)," Draghi told reporters, in response to questions after his prepared speech.
"QE has been shown to be effective in the U.S. and the U.K... There is enough evidence to say that it could be effective."
The value of the euro rose 0.58 percent against the U.S. dollar to $1.23 on the ECB chief's remarks.
The ECB has already launched a raft of measures to try and kick-start the euro zone economy—including ultra-low-rate loans to bank and asset backed securities. But the 18-country zone is still struggling economically and consumers and businesses are still not borrowing. The central bank is facing pressure to act further—including a program to buy sovereign bonds.
