The people who benefited most from the extension of the deposit guarantee were the depositors in the guaranteed banks.
So charge all those depositors on the night of the guarantee 10% of their deposit in excess of €20,000.
Charge those in Anglo and Irish Nationwide an additional 40% as they would have lost everything.
It wouldn't apply to deposits in Credit Unions, although Credit Union deposits in Irish banks would be subject to the same deduction.
I fear alot of people reading this post will begin a mass withdrawal of their savings from Irish banks before the upcoming draconian budget.
