€213.7m in fines were collected by the Central Bank's enforcement division last year, the highest amount imposed in a single year to date.
The fines include €100m levied on Bank of Ireland and €83m on AIB arising from the conclusion of the tracker mortgage examination.
During the year the regulator also published 112 warning notices in respect of unauthorised firms, up 24% on the previous year.
Three individuals had their pre-approval for a senior executive position in a regulated firm refused on fitness and probity grounds.
While the bank also issued its first assessment decision related to market abuse legislation, imposing a fine and professional disqualification on Philip Lynch, a former non-executive director of drinks group C&C, for insider dealing in the company’s shares.
The bank received 245 protected disclosures during 2022, up from 231 a year earlier.
It also dealt with 94 applications for derogations from sanctions arising from the Russian war in Ukraine and completed the assessment of 68 of these, with 41 authorised.
The details are contained in the Central Bank’s annual report for 2022, which also outlines how it made a profit of €575m.
This is down €746.5m from a profit of €1.322bn recorded in 2021.
The decrease was due to an increase in provision for financial risks, a drop in net interest income caused by higher ECB rates and an increase in net payment due to the ECB compared to a year earlier.
The bank warns that it has assumed new and additional financial risks as part of its objective of maintain price stability and this has necessitated the expansion of its balance sheet.
"Going forward, however, these additional financial risks will likely have a material effect on the profitability of the Central Bank, and losses are anticipated over the coming years," it said.
"The challenge posed by balance sheet interest rate mismatch to profitability is not unique to the Central Bank."
"Other euro area national central banks are exposed to the same risks, with some signalling that losses are likely in the short term."
It added that in order to mitigate the increased financial risks facing the balance sheet in recent years, it has strengthened its overall financial buffers, increasing its general reserve from €1.3bn in 2008 to €5.9bn in 2022.
