The Finance Minister is to write to all bailed-out banks tomorrow and order the preservation of any taped phone calls in the run-up to the bank guarantee in 2008.
The Taoiseach has confirmed to the Dáil that recordings similar to the leaked so-called 'Anglo Tapes' do exist in other financial institutions.
Earlier the Finance Minister said the Oireachtas inquiry into the banking crisis could demand all electronic recordings of calls in the possession of banks.
Michael Noonan says if the banks were not already on alert that such material would be wanted, then they should be from today.
"I assume that there are recordings of calls in and out of Treasury in the other main banks as well and the banks should be on alert if they weren't before that this electronic data may be required by the Oireachtas inquiry" he told the Dáil.
Michael Noonan has also confirmed that the 'Anglo Tapes' were given to the Financial Regulator in 2009 but that an inquiry was suspended pending possible criminal prosecutions.
He has also confirmed that an investigation by the special liquidator of the Irish Bank Resolution Corporation (IBRC) is underway to see if the leak of the tapes to the Irish Independent came from there.
