The city provides a low-tax English-speaking location and has similar laws and regulations to its UK neighbour. Barclays has also settled on Ireland's capital city for its new EU hub, and may move about 150 roles there, people familiar with their plans said in January.
Executives are debating whether to locate Bank of America's broker-dealer operations in Paris or Frankfurt, rather than Dublin, according to two people with knowledge of the firm's discussions.
The business could be spread across multiple locations, said the people, who declined to be identified because the details of the plan are private.
While Bank of America didn't publicly disclose which other cities it would move people to, one of the firm's top executives in Germany said in March that some jobs would probably relocate to Frankfurt, Madrid, Luxembourg and Amsterdam.
Frankfurt has emerged as the biggest winner in the fight for thousands of London-based jobs that may have to shift after Brexit. Morgan Stanley, Standard Chartered and Nomura Holdings are among lenders that have already picked the city for their new EU base. Like Bank of America, most banks are likely to opt for a model that spreads jobs across multiple countries.
