Thank you for contacting Visa Europe.
Visa sets it daily exchange rates within the previous day's market wholesale high and low rate range or by reference to government-mandated rates where these apply.
Visa goes to great lengths to check its sources for market wholesale rates and that its information is accurate and correct.
Our main provider for exchange rates is Reuters, which is a wholesale market collector of information from a large number of contributors. However, Visa uses various sources and can change sources at any time.
Visa's ability to purchase currency in large volumes allows its members - the banks and other financial service providers - to offer their cardholders the benefit of a competitive currency conversion transaction rate.
You can check out Visa's exchange rate via the link below. However, please bear in mind that, in addition to this, payment card providers often charge their cardholders currency conversion fees, They can charge different rates, so consumers should shop around for the card offering that best suits their needs.
Currency conversion is an example of competition within the Visa payment system and the benefit that competition brings to consumers.
