The ECB deposit rate is EU-wide, so should Bunq's deposit rates be available for all customers in countries where Bunq operates. Otherwise Bunq is discriminating against many of its loyal customers.
Given Bunq's practice I am considering moving my business elsewhere to a competitor that doesn't follow such practice, even if the rate is the same or less than Bunq's.

Bunq should at least perform a review of their practice based on customer feedback & if possible give an explanation.
