The risk that they're concerned with is if every bank is using AWS, then AWS goes down, the entire UK economy crashes until it's back up.
Even if AWS itself is more reliable than every bank's on-prem solution, that's no good if it goes down for everyone simultaneously and I can't just use a backup credit card.

As an example, there's no visibility or processes in place to ensure that all these banks aren't sharing the same availability zone. They're likely only looking for ways to mitigate these risks, not necessarily a complete return to self-hosting.
