If they wanted access to your banking app, they'd make you enter your password anyway.If you enable the fingerprint unlock on the app you have immediate access to your entire banking profile and considering that you also receive 2 factor authentication on the same device in theory somebody can literally hold you up and empty your accounts in a matter of minutes
If this is your concern, you shouldn't have a banking app on your phone in the first place...
