Frequently asked questions
What is the mid-market rate?
The midpoint between global buy and sell prices — the rate you see on Google or Reuters, with no markup added.
Is a zero-fee transfer really free?
Rarely. Providers advertising no fees usually widen the exchange rate margin instead, which costs more on large amounts.
