Because you don't want any phone in the world to be allowed to access any bank account in the world by just giving a name and password.
Fingerprinting is a form of 2 factor authentication, it's easy to perform and it's relatively efficient against fraud.

When the banking app request validation, you use your fingerprint to authenticate and the secure enclave sends the username and password to the app. The fingerprint scanner is connected directly to the secure enclave. When you sell your phone, you go through the process of erasing your phone, the encryption key is destroyed and your fingerprint is no longer valid.
