Marco Três newsroom · edited by Annie GrellmannUpdated on
In Paraguay yes, often at a good rate; in Brazil and Argentina, use local currency
The US dollar is widely accepted in Ciudad del Este, Paraguay, often at a good cash rate. In Brazil (Foz) and Argentina (Puerto Iguazú) the dollar has limited acceptance: use reais and pesos for daily expenses, exchanging what you need at currency offices.

Quick answer: Yes, you can use US dollars at the Triple Frontier, particularly in Paraguay where dollars circulate well and are commonly accepted, especially for large purchases like electronics which are often priced in USD. However, in Brazil shops operate in reais and in Argentina the peso is standard currency. It's recommended to bring cash dollars for major purchases in Paraguay and check current exchange rates.
Paraguay: dollars circulate well, especially for big purchases (electronics are often priced in USD). Brazil: shops work in reais. Argentina: the peso rules daily life. Bring some cash dollars for large purchases in Paraguay. Check the exchange rate.
