Duffy has held a number of senior roles in the international banking industry including, most recently, the position of CEO at Standard Bank International. He was previously president and CEO, Americas, ING Barings.

From 1987 to 1997 Duffy was business manager of information technology at Goldman Sachs International.

AIB executive chairman David Hodgkinson said Duffy brings with him a wealth of international experience and a sound knowledge of the local market. He also has a proven track record in successfully managing banks through challenging times.

"He is ideally suited to the task of leading AIB’s extensive restructuring and delivering the business performance that will best serve its customers and return the bank to sustainable viability," added Hodgkinson.

Hodgkinson will remain on the board of AIB in the role of non-executive chairman.
