I don’t think it is comparable to Wise’s fast and easy transfer. Wise’s fast and easy transfer allows the user to use a debit or credit card, in return for a higher fee. This is not the case for Monzo. Alternatively, Wise’s low cost transfer involves transferring money from your bank account into Wise, which is essentially what you are doing when you transfer money using Monzo directly.
The old Monzo platform charged the low cost fee, so essentially it seems that Monzo has upgraded the experience and also it’s pricing. Monzo should charge the low cost fee.
