European stocks look set to extend gains, with U.S. stock futures signalling a firm start on Wall Street. Financial spreadbetters called the main indexes in London, Paris and Frankfurt to open up as much as 0.4 percent.
Markets rose sharply after ECB President Mario Draghi said on Thursday the bank would do whatever was necessary to protect the euro zone from collapse, raising expectations it will move quickly to tackle skyrocketing borrowing costs in countries like Spain.
Analysts said Draghi's comments, coming ahead of the bank's policy-setting meeting next week, could signal a resumption of the ECB's sovereign bond-buying scheme known as the Securities Markets Programme which has not been used for months.
"This would prove a welcome relief for struggling economies and their borrowing costs," said Andrew Taylor, market strategist at GFT.
MSCI's broadest index of Asia-Pacific shares outside Japan climbed 1.8 percent, pulled higher by a 3.6 percent gain in the technology sector. At current levels, the index was on track for its biggest daily rise in a month, but still set for a small weekly drop.
Korean shares outperformed their Asian peers to jump more than 2 percent to a one-week high after Samsung Electronics Co, the world's top technology firm by revenue, posted a record profit for the June quarter, pushing its shares up nearly 5 percent.

The euro was further supported by expectations that the U.S. Federal Reserve could offer some additional stimulus at its policy meeting next week to ensure a delicate U.S. recovery remains on track.
