Not sure if you actually follow Brexit but the situation now is completely different to the last 2 years. Michael Gove this week formerly advised businesses that the UK is going down the hard Brexit path i.e. leaving the customs union, single market and with full regulatory divergence from the EU. Under these circumstances it is impossible to run a business like N26 in the UK serving the EU.
> Under these circumstances it is impossible to run a business like N26 in the UK serving the EU. you have this the wrong way round: they are a bank based in the EU that was passporting their German (EU) license into the UK in the near future they will not be permitted to operate in the UK as the UK will no longer accept their EU banking license
The UK may end up being 'forced' to not recognise such licenses in retaliation if the EU refuses to recognise British licenses. This is quite likely to happen because the EU has a track record of revoking financial licensing as part of trade wars with European countries. For instance they revoked acceptance of Switzerland's financial licenses as part of trying to pressure the Swiss government to cede significant powers to Brussels.
