The conversion of one currency into another and the market where that happens.
The conversion of one currency into another, and the wider market where those rates are set. For anyone earning in one currency and spending in another, the rate and the hidden margin baked into it quietly shape how much you keep. It is the underlying exchange itself, not a foreign transaction fee, which is one specific charge your bank adds on top of a conversion.
Someone paid in dollars but living on euros converts money every month and never checks the rate they are handed. Over a year the margin skimmed on each conversion adds up to a meaningful slice of income, lost not to any single visible fee but to the spread on the exchange itself.
Poor exchange rates and hidden margins quietly erode income earned and spent across currencies.
The difference is the whole point, so here is each one in a line.
Foreign exchange is converting one currency to another, and the mid-market rate is the true midpoint before anyone adds a markup.
A foreign transaction fee is a charge your card or bank adds for spending in another currency, and dynamic currency conversion is the trap where a foreign shop or ATM offers to bill you in your home currency at a deliberately poor rate, which you should decline.
