Currency exchange in Foz do Iguaçu is part of the routine of those visiting the triple border. In just a few steps, the tourist can leave Brazil, enter Paraguay and cross into Argentina. This intense movement between countries makes currency exchange an essential aspect of travel planning.
First-time visitors are often surprised by the variety of currencies in circulation. Brazilian reais, U.S. dollars, Argentine pesos and Paraguayan guaranis coexist in restaurants, stores and tourist attractions. It is natural for questions to arise about where, when and how to exchange money to make the most of the trip.
In each country, choosing the right currency directly impacts the budget. A meal in Puerto Iguazú may cost more if paid in reais, while shopping in Ciudad del Este is usually more advantageous in dollars. Knowing the best way to exchange money avoids waste and guarantees peace of mind for the traveler.

How to get the best rate?
Exchanging money in Foz do Iguaçu can be cheaper if you know how to take advantage of the right tools and timing. Check out the main tips to save on exchange in 2025:
- Use online comparators
Platforms like MelhorCâmbio and Câmbio Store show in real time the rates practiced at exchange houses throughout Brazil, including Foz do Iguaçu. This allows tourists to know if the rate offered in person is truly advantageous.
- Negotiate at physical houses
Many tourists don’t know, but it is possible to negotiate in exchange houses, especially when exchanging more than R$ 2,000. Ask directly if there is a discount for cash payments, since there is strong competition downtown.
- Avoid exchanges on weekends
Rates are usually worse on Saturdays and Sundays. In some cases, the difference from Saturday to Monday can reach 3%, which has a significant impact when exchanging larger amounts.
- Consider digital exchange
Services like Wise (formerly TransferWise) remain good alternatives in 2025. Digital conversion usually has more competitive rates than physical exchange, and in some scenarios has been up to 10% cheaper.
- Withdraw directly from ATM24h machines
A practical solution in Foz do Iguaçu is to use ATM24H, located in shopping malls, airports and hotels. They operate 24 hours a day and allow you to withdraw reais directly from your international account, with automatic conversion by the issuing bank. This is an ideal alternative for emergencies or for those who prefer not to carry large amounts of cash.
