AIB is planning to sell its first senior unsecured transaction since the country's banking system collapsed in 2008 in a further sign of recovery for Ireland.
The bank has mandated Deutsche Bank, Goldman Sachs, JP Morgan, Morgan Stanley and Nomura to arrange an investor update for this afternoon ahead of the potential deal.
While AIB has sold public bond market transactions, this is the first time that investors will be able to buy the credit on an unsecured basis.
Bank of Ireland is the only other Irish bank to have raised senior debt in the public market. It sold a €500m three-year bond in May.
