Banks will run Private #XRP Ledgers, and will issue their own stablecoins on top of it. They will transact their day to day business privately as usual.
At a point (say daily/weekly/monthly) they will settle out to the PUBLIC ledger through liquidity hubs.

No bank in the world will publicly reveal their transactions / customer accounts to the public.
This is privacy 101, it’s the way it’s always been and will not change due to new technology.

Once a batch of private transactions are bundled, sent to Liquidity Hub, those bundles will not include ANY customer data, like a stash of blind data with a value.
The Liquidity Hub is a second layer of obscurity where this 3rd Party will trade bundles with other bundles.
