Every Brazilian repeats the same line: "never exchange money at the airport." The line is almost right, but not an absolute rule. In May/26 we ran the real test: we simulated exchanging USD 500 (or the EUR equivalent) at airport, city center, and bank across five cities. We show the effective spread at each point, the difference in reais, and the one rule that matters: exchanging beforehand in Brazil is almost always the best deal — and when you can't, there's a correct order of preference at the destination.

There's a piece of mythology repeated for thirty years: "never exchange money at the airport." It's almost true. Almost. The problem is that the line became dogma and no one measured the real size of the difference, nor compared it with the alternative — the city center, the destination bank, or pre-exchanging in Brazil. In May/26 we ran the test in five cities: São Paulo, Rio de Janeiro, Lisbon, Madrid, and New York. We took USD 500 (or EUR 500, depending on the location) and simulated the real operation at three points in each city. We noted the spread, the fee, the effective rate, and the net amount delivered.
This article is the report. It shows city by city, point by point, in May/26. And it shows the only strategy that survives the test in all markets: exchange beforehand, in Brazil. When that's not possible, follow a clear hierarchy of lesser evils.
The premise no one tests
The Brazilian tourist arrives at the airport, sees the exchange booth with its blinking digital panel, reads "USD buy 5.68 sell 6.12" and hesitates. Looks at the clock, looks at the taxi line, looks at the cashier. Exchanges. Leaves with the feeling of having paid too much but no way to measure how much. And since the panel shows the number and the cashier hands over the cash, the brain closes the deal.
The problem is that the airport spread isn't "a little higher than the bank's." In May/26 it's, on average, three to seven times higher than a downtown commercial exchange house. In some cities, ten times higher. The panel is the visible part of the iceberg. The invisible part is the fixed fee, the 3% to 8% commission on the amount exchanged, and the aggressive rounding that grabs a few more reais per operation.
To measure this fairly, we simulated the same operation in five cities. We exchanged USD 500 at the airport, then USD 500 at a downtown exchange house, then USD 500 at a local bank. We noted how much we received. We compared with the interbank rate (PTAX in Brazil, ECB for the euro, midmarket Reuters for the dollar) on the day of the operation. The result is in the tables below.
São Paulo — Confidence Downtown vs GRU vs Banco do Brasil
Scenario: a Brazilian leaving the country wanting to buy USD 500 in cash for the trip. Interbank USD/BRL rate in May/26: R$ 5.40.
| Point | Displayed sell rate | Fixed fee | Embedded commission | Amount paid (USD 500) | Effective spread |
|---|---|---|---|---|---|
| Confidence Câmbio (downtown, Av. Paulista) | R$ 5.52 | R$ 0 | included | R$ 2,760 | 2.2% |
| Cotação Câmbio (downtown, R. Augusta) | R$ 5.54 | R$ 0 | included | R$ 2,770 | 2.6% |
| Banco do Brasil (downtown branch) | R$ 5.68 | R$ 25 | on the operation | R$ 2,865 | 6.1% |
| GRU Airport exchange (terminal 3) | R$ 5.98 | R$ 0 | included | R$ 2,990 | 10.7% |
Difference Confidence Downtown vs GRU on USD 500: R$ 230. And Banco do Brasil, which many people think is "the safe place," charges almost triple the spread of the downtown exchange house. In SP the rule is crystal clear: Confidence or Cotação downtown, always.
Rio de Janeiro — Cotação Downtown vs GIG
Scenario: same. Interbank rate May/26: R$ 5.40.
| Point | Displayed sell rate | Fixed fee | Amount paid (USD 500) | Effective spread |
|---|---|---|---|---|
| Cotação Câmbio (downtown RJ, Rio Branco) | R$ 5.53 | R$ 0 | R$ 2,765 | 2.4% |
| Daycoval Câmbio (Copacabana) | R$ 5.56 | R$ 0 | R$ 2,780 | 3.0% |
| Itaú (Copacabana branch) | R$ 5.70 | R$ 30 | R$ 2,880 | 6.5% |
| GIG Airport exchange (terminal 2) | R$ 5.92 | R$ 0 | R$ 2,960 | 9.6% |
GIG is less aggressive than GRU in May/26 (perhaps due to internal competition between booths), but still loses R$ 195 against downtown. The Rio Branco exchange house remains the best point in Rio for tourists leaving the country.
