Argentina is well-known for its currency volatility and restrictions, often referred to as cepos cambiarios. At the start of 2025, President Javier Milei’s government set a single official rate for the U.S. dollar, putting an end to more than 15 different exchange rates. Some of those rates are still used in specific sectors, but for everyday travelers and locals, what really matters is the unified rate.

Today, the dollar has a single value, which you can always check on the official website of the Central Bank of Argentina: bcra.gob.ar.

Of course, the exchange rate still fluctuates based on political and economic factors. While 2025 has brought more stability, the country continues to feel the effects of inflation and higher living costs.

Practical tips for travelers

If you’re visiting on vacation, here’s the good news: in Buenos Aires, you can pay for almost everything with a credit card, debit card, or even with contactless from your phone.

Still, it’s smart to bring some cash for small purchases, tips, or emergencies. Here are my best tips:

• Bring newer, higher denomination bills. If you plan to exchange at cuevas (informal exchange houses), $50 and $100 bills are preferred. Smaller bills like $10 or $20 usually get worse rates.
• The fun fact: the “arbolitos.” On Florida Street, you’ll hear people saying “cambio, cambio.” These are the arbolitos—nicknamed this way because, just like little trees, they’re always standing in the same spot. They guide you to informal exchange houses. These aren’t illegal, just not official like banks.
• Banks. If you’d rather keep things simple, you can always exchange at a bank. There, it doesn’t matter if your bills are old or small denominations. Just remember to bring your passport and check opening hours: banks in Buenos Aires are open Monday to Friday, from 10:00 am to 3:00 pm.

Things to keep in mind

• Even with a more stable exchange rate in 2025, Argentina still has inflation. Don’t exchange all your money on your first day unless your stay is under two weeks.
• Not every ATM dispenses U.S. dollars. To avoid issues, it’s better to bring some cash with you from home.
• Use your cards for most expenses. Even public transportation in Buenos Aires accepts them.

My final recommendations

1. Bring some cash, but don’t exchange it all at once if you’re staying long-term.
2. Rely mainly on your credit or debit cards.
3. Trust your intuition and exchange money where you feel most comfortable.

I hope this guide helps you understand how Argentina’s exchange system works in 2025.

See you next time!
