Economists and pro-remain campaigners warned ahead of the vote on June 23 that major European banks might swap London headquarters for Dublin, Frankfurt or Luxembourg if the U.K. quit the EU.
HSBC and Barclays, two of the U.K.'s biggest banks, have said they will remain in London, but ahead of the vote, the latter did say it might move up to 1,000 jobs to Paris, according to media reports.
Hunter said Dublin, Frankfurt and Amsterdam might appeal to companies looking to refocus operations in major cities in EU countries with well-educated, English-speaking workforces and attractive tax arrangements for both corporate entities and individuals.
"But they don't want to have to move again if there is an EU problem in these countries (which then look to leave the bloc) as well," he said.
To avoid this, companies might instead look to do cross-border mergers with other businesses in EU countries. "They might want to do that soon," Hunter said, but added that this option had not proved popular with companies in the past.
Alternatively, U.K.-registered companies might look to covert to mainland-European ones, he said.
"Those in markets benefiting from the (EU) single market, may look around (at various options)," Hunter said.
