Real Falls 3.2% in Paraguay, Dollar Hits R$ 5.22: What It Means for Your Border Purchases

Between September 4 and October 5, 2026, the purchasing power of the real in Paraguay (measured in guaraní) fell 3.2% – meaning the real earns less when converted. During the same period, the real also fell 1.5% in Argentina.

The official dollar rate (PTAX) used as a reference was US$ 1 = R$ 5.22, which is among the highest values in our 141-day series, indicating a moment of real weakness. Additionally, R$ 1 = 1,121 guaraní and R$ 1 = 292 Argentine pesos. Guaraní is the currency of Paraguay and Argentine peso is that of Argentina; the rates show how many of these currencies you get for one real.

For those crossing the border to shop, the depreciation means that Brazilian money buys fewer goods in guaraní and pesos. If you previously exchanged R$ 100 for about 112,100 guaraní, you will now receive approximately 108,000 guaraní. The same applies to Argentina, where R$ 100 now yields about 29,200 pesos, less than before.

What this means for you:

• Bring a larger amount in reais or exchange before crossing, as the rate may become even less favorable.
• Check the daily exchange rate at currency exchanges or apps before buying, especially if you plan to purchase electronics or clothing that are usually priced in guaraní.
• Consider paying in dollars (US$) when possible, since the dollar is high in reais but may be more stable relative to the guaraní.
