The causes of Ireland's banking crisis will be examined later today by the Banking Inquiry.
Klaus Regling, and Trinity College Dublin Professor Philip Lane are appearing before the inquiry, as the context phase of the inquiry continues.
The economic effect of the Eurozone on its policies will also be looked at in relation to Ireland and the banking sector.
Chairperson of the Banking Inquiry Ciaran Lynch, says economists and banking experts are an integral part of the inquiry's first stage.
He said: "To draw upon their expertise and their examinations that they have done to inform the inquiry when it moves into what is called the nexus phase, at which time we will be dealing with the personalities and individuals who were actually at the decision-making side of things during the crisis period.
"That is, both in the lead-up to the banking guarantee and the eventual bail-out which took place two years and two months later."
