Ireland will try to re-enter bond markets as planned at the end of next year but will borrow commercially again only if it wants to, a government minister said on Tuesday.

We intend still to be in a position to re-enter the markets at the end of 2013 should we want to do so, Education Minister Ruairi Quinn, who served as finance minister between 1994 and 1997, told Ireland's Newstalk radio station.

Comments from Citigroup chief economist Willem Buiter prompted a spokesman for EU Economic and Monetary Affairs Commissioner Olli Rehn to tell a news conference it was unhelpful to fuel speculation about Ireland possibly needing a second bailout from the EU and the IMF.

Buiter said on Monday that Ireland would need to restructure part of the country's bank bailout bill or else it may have to follow Greece in making investors take losses on its sovereign debt.
