The euro gained against the dollar while German bond prices held steady on Wednesday ahead of Italy's first debt sale since its credit rating was cut due to political uncertainty.
Yields are expected to climb at the sale of up to 7.25 billion euros ($9.4 billion) of new Italian bonds although demand for high yielding assets and the European Central Bank's promise to underpin the euro should limit the rise.
However, the German Bundesbank warned on Tuesday that the euro zone crisis was far from over and some investors remain cautious about the outlook.
"Our view is that these bond yields are going higher at some point. There will be an issue within Europe, within Italy, there will be something that pushes these yields higher," said Patrick Armstrong, managing partner at Armstrong Investment Managers.
Germany also sells new 2-year bonds later in an auction which will reveal whether the Bundesbank comments have added to the appeal of safe haven assets.
Markets are also waiting for January industrial production figures from across the euro area, after poor German, UK and French data pointed to renewed weakness in the region at the start of the year.

Ahead of the data and the debt auctions, the euro had edged up 0.2 percent against the dollar to $1.3060 though was well within the $1.2955-$1.3135 range seen so far this month.
