This is partly due to a stupid law that forbids banks from letting the account holder know of anything if "financial crime" is suspected (of course, financial crime is totally fine when it's done by the ruling class).
I'm not sure if the law technically applies given that the account isn't even open but I would expect the same "financial crime" checks to be run upon initial account opening too.
The problem is that ultimately it's not just racism but a result of dumb legislation.
edit: And to answer your question, I just moved here, I got a tier 2 visa and a UK address
I would not throw the r word around every time a commercial/credit decision is not what you wished for.
