It's all swings and roundabouts.

If the pound loses value in the medium-run, foreign investment in the UK will increase.

Brexit, if negotiations are acrimonious, will be worse for the EU than it will be for the UK, so I don't expect much of a long-term shift in the GBP-EUR exchange rate.

Outside the EU, the UK can make itself an even more attractive place to do business, no longer hampered by EU laws and regulations.

In any case, I think Brexit will be curtains for the current incarnation of the EU. It will either have to reinvent itself significantly, or collapse and be replaced by a new union.
