For Bank of America, one of the top four banks in the United States, the cost of Brexit, including moving some of its operations to Dublin, has been a hefty $400m (€354m) while for Britain's Barclays the cost has been perhaps as much as $200m.
But for both banks, there is no moving back to London for the operations that have been moved to Dublin, Paris and Frankfurt, a sign that the damage to the British economy from Brexit in terms of losing high-paying finance jobs and expertise will be permanent.
"Hundreds of millions; maybe $400m," Anne Finucane, vice-chairman at Bank of America, one of the top four banks in the United States, told a financial conference here as she explained the impact of Brexit.
"Multiply that by the number of financial institutions that are doing the same thing and it adds up," Ms Finucane told the European Financial Forum in Dublin of the impact that Brexit will have on the UK banking sector.
Bank of America's European banking headquarters is now in Dublin. It has shifted $50bn in assets here and will employ close on 800 people.
"Even if there were no Brexit, that has happened, there isn't a return there. The bridge has been pulled up on that," she said.
That was a message echoed by Gerry Grimstone, chairman of Barclays Bank, which will become the largest bank in Ireland in terms of assets post-Brexit.
"I have to say that the process over the last two years has been as smooth as we could possibly have wanted it to," he said of Barclays dealings with Irish and European regulators over setting up its headquarters here.
On the costs of Brexit to Barclays, Mr Grimstone said the bank had spent less than Bank of America and probably in the order of "200, 150, 200 million".
So far for Ireland, Brexit has been an unalloyed bonus with companies like Barclays and Bank of America relocating, and the process has so far created 4,500 new jobs here.
However, with the March 29 exit date from the European Union now just six weeks away, the costs could soon start to mount.
The Central Bank of Ireland says a hard Brexit would lop four percentage points off economic growth here, meaning 2019 could come in at just 1.5pc, although he stressed a strong budget position would allow the State to run a fiscal deficit through the operation of the automatic stabilisers on tax revenues and transfer payments.
Governor Philip Lane said he believed that financial risk from Brexit had largely been eliminated, a comment echoed by Claire Woodman, head of Europe, Middle and Africa at Morgan Stanley & Co.
"Central banks and regulators have really tried to ensure that financial stability risks have been taken off the table."
