The agency that borrows money on behalf of the State has raised another €1.5bn through the sale of Government bonds on international markets.
The cost of borrowing the money was slightly lower than in last month's auction.
The National Treasury Management Agency sold €500m worth of bonds due to be repaid in 2014 and another €1bn of ten-year bonds to mature in 2020.
It said it was satisfied at the outcome, as it showed that appetite for Irish bonds remained strong despite market volatility.
The NTMA said it has now completed 99% of its borrowing programme for this year, which was aimed at raising €20bn.
The next bond auction is due on 21 September.
