I’d agree with this, it would be confusing to say “for interest you earn it’s included” but “interest you pay on your overdraft it’s excluded” (presuming they didn’t align the two).
It goes back to the debate people had on the forum a number of months ago.
Personally I feel the current position on how it works is the simplest and thus the better way. If you’ve got an investec pot someone could mistake it for being included in their monzo balance and thus be confused at the annoying of interest they are receiving.
I hope this doesn’t start the debate again
