The keyword is “private.” The redundant system all the banks maintain can be reduced to a private, permissioned blockchain, creating a network for the banking system to handle their own transactions in addition to a seamless inter-bank communication.
I doubt a network for just one bank can be that useful compared to the current situation.
Also, I’d say that every bank has (had?) a team researching the blockchain.
