Banks are keen to encourage us to use them for direct debits. Some require your to have direct debits with them to earn perks (like cashback). Monzo doesn’t do this but does have features to try to encourage you to use it for direct debits (such as bill pots).
Do banks directly earn any money from direct debits (something similar to interchange for card payments)?
Or is the desire to incentivise direct debit use entirely because it makes it more likely you will use that bank as your main bank and therefore easier to sell various financial products to you?
