We took USD 500 and simulated the same exchange at three points in each city — airport, downtown exchange house, and bank — in São Paulo, Rio, Lisbon, Madrid, and New York. The maximum difference exceeds R$ 280 in a single operation. And it isn't always the airport that's the villain.

Airport exchange counters charge an average spread of 8% to 14% over the interbank rate. Downtown exchange houses vary between 1.5% and 4%. Banks at the destination, between 3% and 6%.
On USD 500 exchanged, the difference between the worst point (airport) and the best point (city center) reaches R$ 280 in a single operation in May/26.
The optimal strategy is almost always: exchange **beforehand**, in Brazil, at a downtown commercial exchange house (Confidence, Cotação, Daycoval, Travelex). Observed spread: 1.2% to 2.5%.
When you can't exchange in Brazil, the rule is: **destination city center > destination bank > destination airport**. Never reverse it.
The airport is only worth it for the *minimum amount* (US$ 20 to US$ 50) covering transport to the hotel. The rest, exchange downtown.
