Why is my Brex spend higher for purchases in another currency?
The Brex help pages give 3 common reasons. The first to rule out: Purchases in a currency other than your billing currency can include an exchange rate markup, so the converted amount can be a little higher than the merchant's price at the market rate.
Is it broken, or just quiet?
A number can fall because fewer people came, or because something stopped counting them. Below are the causes the Brex help pages give, and how to check each one yourself.

How does Brex work with Feder?
- Connect Brex to Feder and it joins your Money apps.
- When you connect Brex, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.
Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.
See whether you can trust the numbers in Brex, one of your Money apps. Feder only reads. It never changes anything in Brex.
