They do not 'need' anything. Apparently there's some utility for a cryptographically signed ledger, but I suspect that's a 'blockchain' in name only.

EDIT: I remember some banking 'crypto' projects announced by several institutions across the globe. Whether they are real projects or just a way to try to attract investments by pitching the latest fad, I do not know.

One is mentioned in the article, JPMorgan's Onyx. But as always, if your system is not open to the public and doesn't need to protect against hostile actors, the overhead of a blockchain is a waste. The technology that JPMorgan is looking for is called... a database.
