Why you were charged more than the exchange rate
Four usual suspects, and they stack.
Almost always one of four things: a foreign transaction fee of around 3% from your own bank, dynamic currency conversion because you were billed in Australian dollars, a merchant or ATM surcharge, or the settlement date moving the rate.
The figure you looked up was the mid-market rate - the midpoint between what buyers and sellers are offering. It is a real rate, but not one retail customers are given. What matters is how close you got to it once every fee is counted.
What makes a card charge more than the exchange rate?
They stack, so it can easily be more than one.
1. A foreign transaction fee
2. Dynamic currency conversion
3. A merchant or ATM surcharge
4. The settlement date
How to work out what you were charged
Take the local-currency amount on the receipt, divide the Australian dollar amount on your statement by it, and compare that rate against the mid-market rate for the day. The gap is your total cost, as a percentage:
- Under about 1%. A good result. A fee-free card at the network rate.
- Around 3%. A foreign transaction fee, and nothing else obviously wrong.
- 5% to 9%. Dynamic currency conversion, probably with a fee on top. Check whether the receipt shows an amount in Australian dollars - that is the tell.
- Well above that. Look for a separate surcharge or a cash advance, particularly if the transaction was an ATM withdrawal on a credit card.
Can you dispute a dynamic currency conversion charge?
Sometimes, if the choice was never actually put to you. Visa requires that merchants and ATMs let the cardholder accept or decline the conversion and must not choose on their behalf, and that they do not use devices like font size or colour to influence the decision. Mastercard requires the choice be offered before the cardholder enters a PIN. If a terminal converted without asking, or buried the local-currency option, contact your card issuer with the receipt and the transaction details and say the conversion was applied without your consent.
If you simply accepted a poor rate that was shown to you, there is realistically nothing to dispute - which is why declining at the terminal is the whole game.
The habit that saves the most: when a terminal or an ATM offers to charge you in Australian dollars, decline it and choose the local currency. Why that matters.
Frequently asked questions
What is the mid-market rate?
The midpoint between what buyers and sellers are offering for a currency at that moment. It is the rate search engines and financial sites display, and the right benchmark to compare against. Almost nobody in retail actually receives it - what separates a good provider from a bad one is how close it gets once every fee is counted.
Why did a pending transaction change amount before it settled?
Because a pending amount is an authorisation, not the final charge. It is converted at the rate on the day it is authorised, then the transaction settles a day or several later at the settlement rate. A movement of a fraction of a per cent is ordinary market movement. A jump of several per cent is a fee or a conversion, not the market.
Why is the amount on my statement different to the receipt?
Compare the currencies first. If the receipt shows an Australian dollar amount, the merchant converted for you and you are looking at dynamic currency conversion. If the receipt is in local currency and the statement is higher than the network rate, the gap is your bank's foreign transaction fee, a merchant surcharge, or both.
How long do I have to dispute a card transaction?
Raise it as soon as you notice. Card scheme chargeback rights are time-limited and measured from the transaction or the expected delivery date, so a statement you review months later may be outside the window. Contact your issuer with the receipt and the transaction details rather than waiting to see whether it resolves itself.
