Basically the question is "how to understand the 0% fees, but wholesale rates at currency exchange?".
Hi! Thank you for the question and I apologize for the delay with answer.
Let me clarify this moment.
We state that Currencies are converted at a wholesale rate, provided by our bank. We don't charge anything on top of that, that is why Wirex FX Fee is 0% in our fees. And it is true.
However, our bank's rate is not equivalent the Visa exchange rate and the usual difference is about 3% that you can see in the numbers provided by you.
Hope it helps.
No problem, thanks for your time answering.
It does help and although I am still puzzled that the very small transactions get better exchange rate, I understand now that the difference may be at the bank's side too, not necessarily at your end.
Thanks again.
