Don't all these new online banks (Wise, Revolut, etc) get UK bank license and then operate in the entire EU (although UK is no longer in the EU)?
For example, Revolut is a bank in the EU via a Lithuanian banking license, but only an "e-money institution" in the UK (though the application to become a British bank -- and for that matter, an American bank, and other jurisdictions -- is in progress).
Monzo is a UK bank, but opted to cancel their US banking application, and I don't believe is an EU bank either (someone please fact check me here!)
The closest service I have gotten to this was (also not exactly an EU company) American Express - but that was still two different legal entities.
