The number of whistleblowers coming forward to the Central Bank has risen steadily since the introduction of new protections for people making protected disclosures in August 2013.
According to figures arising from a parliamentary question submitted by Fianna Fáil Finance Spokesperson Michael McGrath, the Bank is currently dealing with around 50 whistleblower allegations.
There were 42 such disclosures made to the Central Bank's dedicated whistleblower desk in 2014, with 49 in 2015, and 50 last year.
So far in 2017 there have been more than 40 disclosures made.
The Central Bank does not give a breakdown of the penalties imposed on foot of protected disclosures.
However, the regulator imposed fines totalling €12.05 million in 2016, the largest figure for fines imposed by the Bank in a single year to date.
Last November, a fine of €4.5m was imposed on Springboard Mortgages for wrongly moving homeowners from low interest tracker loans.
Since 2006, 108 settlement agreements have been reached for regulatory breaches, with fines of around €57m imposed.
