Banks and corporations change computers every 3-5 years because accounting love to lease rather to buy
3-5 years is a pretty standard depreciation schedule for IT equipment like computers, peripheral accessories etc.
Computers and laptops (using Straight-line method): 31.67% with a useful life of 3 years.
Computers and laptops (using Written Down Value method): 63.16% with a useful life of 3 years
It really has nothing to do with leasing vs. buying.

Yes ok from an accounting point of view.
But from a functional point of view?
I see how my bank teller works: they connect to a terminal server
I see how my other bank works: a VM that runs AS/400 that is acting as a terminal to their mainframe
Why they’re changing computers so often? The first one can use any PC released in the past 15 years and the second one can use any released in the past 30 years

I can’t speak to your specific examples since I don’t work there.
The reasons beyond caper considerations are things like security, compliance, warranty coverage expiration, standardization across the org, general employee satisfaction, hardware falling out of vendor support.
I doubt the banks computers are single purpose or purchased specifically for each job role. Sure a 15 or 30 year old computer might technically work but there’s no way it’ll meet regulatory security compliance rules.
The home user/hobbyist approach really doesn’t scale to corporate IT.
