Airport exchange vs city center vs bank: who charges less (real test in 5 cities, May/26)
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.

Debit or credit abroad: when each one wins (the real math)
Credit pays 3.5% IOF (Brazilian foreign exchange tax), debit pays 1.1% — but that calculation alone decides nothing. Bank spread, foreign ATM fee, revolving credit interest, and hidden benefits (travel insurance, points, fraud dispute) change the result. This guide does the real math, compares a R$ 500 withdrawal against a R$ 500 credit purchase, and shows which scenario each wins. No magic formula. Just numbers.

The 3.5% IOF tax isn't your enemy: the hidden 6% spread your Brazilian bank charges on every overseas purchase
As of May 2026, the IOF on international card purchases in Brazil is 3.5%, not 6.38%. That outdated number became folklore. Meanwhile, banks charge you a 4-6% spread on top of the wholesale dollar rate — a piece that doesn't even appear by name on your bill. This guide shows the real formula, compares eight cards and global accounts with the final effective exchange rate, and explains why a "no-IOF card" sometimes costs more than a regular one.
