The National Treasury Management Agency said it will seek to raise between €1 billion and €1.25 billion by selling nine and 28-year debt in its final bond auction of the year on Thursday.
The NTMA had originally planned to issue €9-13 billion in long-term debt this year.
But the agency has already this year raised €14.5 billion via benchmark sales and a further €610m in its first ever sale of inflation-linked bonds to facilitate the early repayment of some of its 2010 bailout loans.
The Department of Finance said in September it would seek early repayment of €5.5 billion of bailout loans consisting of its outstanding debt to the International Monetary Fund, Denmark and Sweden.
It said it hoped to save around €150m in the process.
