This isnt a cryptographic problem really. The loan checker is already trusting your bank to give them the correct information, it's only a matter of anonymization (e.g., they could return merchant types instead of merchant names etc.,.) but theres no real incentive for this.

Correct.

People who need the privacy can set up isolated bank accounts and legal entities.

Less cryptography, your accountant will even understand.
