You could set it up so whoever initiates a transfer could get a kind of receipt that proves they initiated a transfer of X dollars to whomever.

So if Alice transfers 5 dollars to Bob and Bob says "What 5 dollars? What are you talking about?", then Alice could say, well here's my receipt, that's signed by my private key and the private key of the FHE bank, that shows that I sent the money to Bob and the FHE bank executed the transfer.

You get this for free with FHE. In the event of a dispute, you can reveal the randomness and message that produce the public ciphertext given the user's public key.
