I wrote previously about charges made to the Chase United Airlines card are beginning to have much lower currency conversion rates than my other cards.
Today is another example of that change. Best street rate at TT Exchange was 35.85 Baht/USD.
Chase, in the above snap shot from my credit card statement, converted my charge to 35.76 baht/$, much lower than the street rate of 35.85 b/$. The charge was made on the 14th of September, and processed or posted on the 16th of September. Chase is a money loser for me today.
Schwab also performs the foreign currency conversion at the moment of transaction.
