OK, here is my opinion on moving cash offshore in general.
Cons:
- deposit guarantee may not be as high
- interest rates may be lower with banks that are in a better financial position
- financial stability of foreign country could change
- more difficult to walk into the bank if it finds itself in diffculty
- taxation of interest abroad is a bit different, I don't believe you pay DIRT but income tax, but get some advice on this
Pros:
- protection from Irish banks that are in dire situations
- protection from the dirty hands of increasingly desparate politicians, i.e. wealth confiscation
- protection from default of Irish state and banks
You could also look further afield, like Germany and Switzerland.
