You might also consider :
1. Perception of inappropriate relationships between banking and the political system . (evidenced again in recent Newspaper reports).
2. Failure so far to prosecute or hold to account anyone in relation to possible banking irregularities.
3. Collapse in public support for Gov.t almost in tandem with collapse in bank confidence.
4. Continued deep and extremely damaging public scepticism (domestic & international) in the ABSENCE of remedial actions on 1,2 & 3 above.
5. Deep & endemic worries about L.T. future of euro given abject failure of EU political and monetary system to address the matter. (Again, evidenced here on AAM in the number of Irish people looking to switch out of euro and into non-euro denominated currencies and countries).
Personally I cannot see confidence returning to the banking system and the euro until all the above are addressed. And I believe that the two are indelibly linked in people's perceptions. You will note from AAM site a considerable debate/enquiries about switching money to countries like Germany anticipating a problem with the Euro itself. Including perhaps the return of local currencies, ie Punt, or alternatively a switch to a two-tier strong and weak Euro. This weighs as much in my opinion as debt problems and a general lack of confidence in Irish banks.
Another issue worthy of consideration is extent of debt held by foreign banks/insitutions in Irelandmaking us very susceptible to external negative perceptions. Japan has a very high level of debt, but most of it is held by the domestic population. Thus despite it's debt levels it has not experienced the systemic problems we have, and that precepitated our need for EU/IMF help.
There is a need for a complete overhaul of the political/banking/regulatory system and a resolution to the EU-wide political/fiscal issues before stability can be restored and confidence returns. Regulatory failure in IRL and the ECB, polticical inertia, weakness and incompetence have all massively contributed to banking crisis. As CiaranT says and Patrick Honohan has intimated, foreign ownership is the likely and best outcome for Irish banks. But the crisis is far from over yet.
