Assuming your phone cannot be trivially unlocked by a thief, it likely is safer to bank on it than on a computer.
Because unless your desktop is dedicated to banking, there's always the chance that one of your other activities will install malware. If you don't use FDE (the majority of people) and you saved your banking password in the browser rather than a password manager (likely a scary amount of people), then theft is also an issue.
Neither of those things are really a problem on a mobile device.
The banking app _is_ the malware. It interferes with the normal use of your mobile device. For example, you can't use developer options to speed up the UI animation speed if you want to access your bank account. You can't install any app you want if you want to access your bank account. etc...
