One of the more odious US credit card practices is charging "exchange rate fees" or "currency conversion fees" on non-USD transactions. I hadn't been paying attention but just looked and saw Chase is charging me
Mind you, this is on top of all the other fees they charge both me and the merchant. And it's pure profit; their friction for a Euro denominated transaction is at most 0.1%. Why do they charge it? Because they can.
Surprisingly Wells Fargo is much better on ATM cash withdrawals. There's a flat $5 fee, so at $1000 an ATM visit I'm paying 0.5% for eurocash. I guess I'm gonna have to start carrying a fat roll.
Thanks to Walter for forwarding me this NYT article. Capital One apparently has a credit card without any stupid conversion fees.
