You mean PoS, which feature is literally that the more you have, the more you can stake, and the more you can earn in return? So basically the system that has built-in wealth concentration?
Yes, but if we are talking about a private permissioned blockchain, there’s no need to obtain returns from staking. It can be even a Proof of Authority tokenless network for what banking care.
Banks are already paying for servers to process and store information. A few validators or collators (quite cheap for a private network) provided by several banks would cost a fraction of what they pay now and they’ll keep owning the data, they could reverse transactions, be covered by several layers of public encryption, guard the user’s wallet/login, etc.
Don’t mix blockchain with the speculative world built on top of it. That’s only an unfortunate use of the technology.

How? They’d be doing extra compute work for no reason (validating already valid transactions), and storing extra data (lots of hashes) for no reason, so it can only make infra costs more expensive. Plus the added complexity meaning you have to hire an extra team just to understand it.

That speculative world as shitty as it is, is the only proven use case of the technology, if you take that away then blockchains are even less useful
