The National Treasury Management Agency said it sold €750m of seven-year bonds - as planned today - at a yield of 0.81%.
The NTMA had sold €1 billion of 30-year debt at a record low yield of 1.3% at its last bond auction in March.
Since then interest rates on Irish debt have risen in line with other countries in a global retreat from fixed income assets.
The agency is already full funded for the remainder of the year and has raised over €10 billion from its guided range of €12-15 billion of debt to fund the state for 2016.
