People here seem to think this is some sort of Orwellian attempt to control them, but the reasons are more mundane and technical - many of them (mine included, from two countries) use security facilities on the phone to secure your accounts.
For example, my HSBC UK app has replaced the little calculator thing they used to ship, and uses iOS face recognition to secure the generation of log-on codes which you need in order to use the web interface, as well as for secure access to the banking app directly.
With a rooted phone they don't have the guarantees that these aren't being exfiltrated, or the app being subverted in novel ways, so they don't want to support it.
You may not consider this a good enough reason, and I have heard it said on HN that 'the banks shouldn't get to control what I do on my computing device!', and that attitude is absolutely fine, but then you'll most likely end up with either less secure banking (meaning more fraud, higher fees etc) or going back to having to have a dedicated security device.

American-like banking detected... who uses checks in 2025?! :)
My GrapheneOS phone fully supports such facilities. I trust your app works on it?
here's all you need to do, if not: https://grapheneos.org/articles/attestation-compatibility-gu...
That looks like an interesting and useful capability.
I don't believe this will satisfy the crowd who want complete control over their systems though, as AFAICT graphene is not rooted by default and will likely fail these attestation checks if you root it. This will also not please the "Passkeys and hardware attestation are evil/non-FOSS by nature" crowd.
Definitely provides more freedom wrt. third-party app stores though.
