I've got no doubt that this suggestion has been made 100 times before, but being a new adopter of the Mobile Client, I can't see how this isn't a major oversight for the Jagex team.
I completely respect that there must be limitations with the client, but being unable to move your bank window, or the chat box are just quality of life features you'd expect from a game in 2020.
If this has already been addressed, feel free to direct me to that post, but having asked the Twitter support I was directed to make a post on here.
Do get in touch!
