AIB has raised another €500 million as part of its plans to start repaying the bailout it received from the State.
The bank issued €500 million of five-year debt at an interest rate of just below 7.5%.
Demand for the debt was nine times the amount on offer.
The bonds attracted offers amounting to €4.75 billion from a wide range of international investors.
Last week, AIB raised €750 million in a bond issue as part of its plan to start repaying €1.7 billion to the State.
The Government has pumped €21 billion into AIB since the financial crisis.
