The National Treasury Management Agency said it will auction €1 billion of 15-year debt on Thursday as it seeks to pre-fund the state in full for next year.
Ireland is already fully funded for the rest of this year.
The NTMA has raised €12 billion out of a guided range of €12-15 billion of debt to fund the state for 2016.
Thursday's bond auction will be the only bond sale scheduled for the final quarter of the year.
Last week, the NTMA said it will not hold any auctions of treasury bills for the second quarter in a row.
