That latest round of bank stress tests to probe the financial position of the main banks here cost the Central Bank €17.6m, which will be recouped from the lenders themselves.
In a Dail reply to Fianna Fail's Michael McGrath, Minister for Finance Michael Noonan said the Central Bank used its own staff, where possible, to keep cost down.
The bill excludes banks's own costs.
The tests looked at the positions of AIB, Bank of Ireland, Ulster Bank, Permanent TSB and a unit of Merrill Lynch. Permanent TSB was ordered to raise €855m following the probe.
