There's a good summary of what may change here: http://www.ft.com/cms/s/0/a3a92744-3a52-11e6-9a05-82a9b15a8ee7.html http://www.ft.com/cms/s/0/a3a92744-3a52-11e6

It's very open at this point (since nothing has been decided really), but it's quite difficult to believe that there won't be any shift at all and that London will be able to retain all of its existing financial services marketshare in Europe. I won't comment on your claims about the quality of life in those cities vs London, but I think it's worth bearing in mind the fact that they already have a significant amount of financial businesses today, and that traders and asset managers may not like being paid in a rapidly depreciating currency. There are really some justified concerns about what's going to happen to the financial industry in the UK post-Brexit, it's not just all mindless fear mongering. Your comparison with Delaware and NY isn't applicable at all really. The US operates under a single currency, with a single set of financial regulators, with an even stronger version of passporting. There are local differences in laws and taxes applicable to corporations between states, but nothing like what you find when you cross an actual border.
