The exchange rate you see quoted is almost never the rate you get. Understanding the gap between them is worth more than watching the markets.
Because the quoted rate is the mid-market rate — the midpoint between what buyers and sellers are offering, with no margin. Nobody trades at it.
Banks and exchange services add a spread on top, and that spread is where most of the cost hides. A service advertising "no commission" is usually taking a wider spread instead, which can be more expensive than a stated fee.
No. That is dynamic currency conversion, and it is consistently one of the worst rates you will be offered. The terminal operator sets the rate and keeps the margin.
Always choose to pay in the local currency and let your own card issuer convert. It feels less certain and it is almost always cheaper.
Airport exchange counters, by a wide margin. They pay high rent for a captive audience with no alternatives, and the spread reflects that.
If you need cash on arrival, withdraw a small amount from a bank ATM instead — decline the machine's conversion offer for the same reason as above.
Not reliably, and be sceptical of anyone selling that certainty. Exchange rates respond to interest rates, inflation, trade flows and politics, and professional forecasters get direction wrong routinely.
For travel, the practical approach is splitting your exchange across a few dates rather than trying to time one perfect moment.
