is that because of a regulation?

coz where I live there is no such regulation, but banks still checks for root because of the support load concern

[NewJazz]

There's a difference between checking for root and checking for non default operating systems.

I suppose the regulation will not mention "rooted devices" but will talk about the bank's obligation for risks and mitigations

[Jensson]

Yeah, as long as banks are held liable for you getting hacked they will want to check the integrity of your system in their programs.

And you don't want a world where banks are not liable for such things, they have to be or they wouldn't spend any resources on their systems.
