Spoke to BNP Paribas Luxembourg , they deal only with customers that interested of saving(multiple currency) and mutual funds together. They push hard for emerging market and gold tracker mutual funds.
Soc Gen Paris return me an email earlier today about non resident saving account & documentation needed(eg. ESB bills, passport, P60, payslips, etc..) . Only problem for me is i don't speak French and you can call them Tel: + 33 1 53 30 87 10 since you speak good french. i am still waiting for them to come back to me details about the interest rates and fees/charges for multiple currency account.
