European shares turned positive and the euro pared losses on Wednesday after the head of the European Commission said it would soon present options for the introduction of euro area bonds.

Confidence in the euro zone was further dented on Tuesday when Italy, where lawmakers vote later on an austerity package at 1800 GMT, was forced to pay the highest interest rates since joining the euro in 1999 to sell 5-year bonds.
Italy is a particular concern because, while Europe's bailout fund can cope with rescuing smaller, peripheral nations, it lacks the financial firepower to save the euro zone's third largest economy.
Markets had been spooked in recent days by renewed talk among euro zone policymakers of an imminent default by Greece, prompted by the country's failure to meet the fiscal goals set out in its European Union/IMF bailout.
The euro was down 0.1 percent at $1.3658 against the dollar, jumping from around $1.3630 before the comments from Barroso.
