The Financial Regulator has hinted that he would not ask for a second term at the Central Bank when his contract expires in 2018.
In an interview with the Financial Times, Frenchman Cyril Roux said that the longer term repercussions of a possible Brexit could be for his successor to deal with.
While he did not rule out staying in Dublin for a second term, he said "As we rebuild the talent I think that it would be a legitimate expectation for the people around me to have a go at running the financial regulation at the Central Bank as well. I think there was a point where there was no one available in the Irish talent (pool)."
Mr Roux took up his position with the Central Bank in October 2013.
The Financial Regulator also told the Financial Times that he was concerned about the major impact Britain's exit from the EU could have on Ireland's banks. He said he had asked the banks to spell out how they would handle the risks and challenges that could emerge from the UK leaving the EU.
Insurance companies will also be asked to examine how they would be affected.
Mr Roux told the newspaper that Brexit could have a very large impact on Bank of Ireland because "all of a sudden half of its business is no longer conducted in the EU, but outside the EU".
He also pointed out that Ulster Bank - which is owned by Royal Bank of Scotland - would no longer be a subsidiary of a bank within the EU, it would be a subsidiary of a non-EU bank.
