The best place to exchange money in Buenos Aires

First, let me share some essential tips for exchanging money in Argentina. Since April 2025, the country returned to having one main exchange rate, and the unofficial “Dollar Blue” has mostly lost its relevance. That means searching for the best exchange rate is now much more straightforward. In this post, I’ll explain what options you have to exchange your money safely and easily.

Important note: Keep in mind that there’s still a restriction on converting Argentine pesos back into foreign currencies like USD or EUR. The maximum you can exchange in cash is 100 USD worth per person each month.

Exchange office – Casa de Cambio

If your local currency is US dollars (USD) or Euro (EUR), then you are lucky. Also, currencies such as the British Pound (GBP), Swiss Francs (CHF), New Zealand dollar (NZD), and others are possible to exchange into the Argentina currency the peso.

There are enough exchange offices available in Buenos Aires. Always take your passport with you when you’re going to the exchange bureau. It’s used that the exchange bureau will only accept banknotes higher than 20 USD or 20 Euro. Changing coins is not possible. Withdrawing money here is not available. Read the article for the best exchange office: “The best places to change your money in Argentinian peso, Dollar and Euro”

I listed all the best places to change your money. Read the extra article

Tips when you go to the exchange office (Casas de Cambio in Spanish)

  • Don’t change all your money immediately. Are you staying longer than 3 weeks? Then change it every 250 USD or EUR. In other Argentinian cities, you will find exchange offices.
  • Don’t accept any extra fee or commission at the exchange offices. This is illegal by Argentinian law.
  • A rate that is 10 ARS under the current rate is acceptable. For example, the actual interbank rate is 1335 ARS for 1 US dollar. If you can get 1325 ARS for 1 US dollar, that’s ok. Go to some different exchange offices and compare them. You get the best rate during bank office hours. Check the current interbank rates on xe.com. Here are the best places to change your money.

Below I give you exchange offices in Buenos Aires with a good exchange rate:

Calle Florida: The Dollar Blue

Not afraid of some negotiation? Then go to the pedestrian street “Calle Florida” near the president’s house (Casa Rosada or Pink House in English). When you walk down the street you will hear people saying “Cambio, cambio”. These people work for a bigger boss.

This is the place to exchange money in Buenos Aires. Be in a strong position to negotiate. Don’t take the first one, but play them against each other. Once you accept a rate after negotiation they will guide you to a small office somewhere located near the street Florida. You will get a better rate if you have banknotes of 100 USD or 50 EUR/GBP.

It’s possible, that once you arrive in the office, they start to negotiate again. Keep with the rate that they said outside. If not, just go outside again.

ESSENTIAL TIP: when you receive your Argentine pesos, stay in the office and count the amount! Check if it is correct. Don’t trust the counting machine.

Western Union in Buenos Aires 

Exchange money in Buenos Aires via Western Union is the safest and best exchange rate to get! Also, the perfect option if you want to travel cashless to Argentina? Then there is Western Union in Buenos Aires. You can send money to yourself in Argentina and pick it up on arrival at one of their offices in Buenos Aires. Western Union at the airports EZE or AEP? More below!

Western Union has several offices in the city. Western Union works together with PagoFacil or they have their own offices. You will have the option where you want to pick up your money. For Western Union, I suggest heading to the office in the street Montevideo 825 (not in Uruguay 😉 ).

The rate at Western Union in Buenos Aires is the best! Western Union almost offers better rates than the black market / dollar blue. The only thing that you need into account is the transaction fee. Both companies are around USD 25 per transaction per USD 500.

The waiting lines at the WU office can be long (up to 1 hour or more) but you make a profit by exchanging money in Buenos Aires with Western Union. That’s a free dinner for two! :-). Western Union HQ office is closed on weekends and holidays.

Take a copy of your passport with you and the Western Union code.

ATM Withdrawal

Don’t use an ATM!!! I caution against ATM withdrawals in Buenos Aires because it’s the least recommended option. The withdrawal commission can get up to USD 15 per withdrawal and the worst exchange rate. So, there are better ways to get Argentinian pesos. Using the ATM is not the best way to exchange money in Buenos Aires! Don’t you have any other options? Go to the bank and take an ATM with the above sign “Cajero Automatico”. These ATMs are for everybody. An ATM with the above sign “Autoservicio” will not work for tourists.

Exchange money in Buenos Aires hotel

Exchanging currency at your Buenos Aires hotel is convenient, but it doesn’t always offer the most favorable rates. Additionally, not all hotels in Buenos Aires provide currency exchange services. Therefore, before approaching the receptionist, it’s advisable to verify the current exchange rate in Argentina and compare it with the hotel’s offer.

This option is particularly useful for securing a small amount of cash to kickstart your trip and for those intending to convert USD, EUR, or other currencies into Argentine Pesos later during their stay.

Exchange money at Buenos Aires airports

A convenient way to exchange money upon arriving in Argentina is at the airports: Ezeiza Ministro Pistarini (EZE) or Jorge Newbery Aeroparque (AEP). You can exchange your currency at the Banco de la Nación Argentina (BNA) office at the official exchange rate or at Sur Finanzas office in the arrivals terminal. While they don’t have the most favorable rate, it ensures you have some cash to start your trip.

Exchanging money at the BNA office Ezeiza International airport is available 24 hours per day. At Jorge Newberry from 06:00 till 23:59. Sur Finanzas at Ezeiza airport is open 24 hours per day, all year long.

Check my article here for the current exchange rates

There are no Western Union offices at either airport. You may come across Correo Argentino as an alternative, but I don’t recommend using it.

Credit card

Paying with a credit card (Mastercard and Visa) is widely accepted in the city and safe to use. Restaurants, bars, and supermarkets mostly accept your credit card for any amount. By April 1st, 2018 all stores have to accept card payment by the law, but often small kiosks, the bakery or newspaper stores around the corner don’t.

Before going to a restaurant always ask if they accept your credit card or check the window for any signs.

Since December 2022, you can pay with your credit card at the tourist exchange rate which is close to the Dollar Blue rate that you get on Calle Florida. However, take into account that touristic activities such as tango shows, bike tours, … will charge you in USD or Argentine peso at the MEP rate. Most of those companies have an international payment terminal to charge you in USD. Because of course, companies want to have USD and not ARS. And then you don’t make any profit with that new rule.

Supermarkets or other stores

A not very know way to change your Dollar or Euro to Argentinian peso is going to supermarkets or other brand store (Havanna, Gift stores, …). At the supermarkets go to the cashier lane and you will see a little announcement with the rate they will give you.

The system works as follows. You buy something small – for example, a little bottle of water. Thereafter, you go to the cashier and pay with your US Dollars or Euros. Use a note of 50 Euro/US Dollar or smaller notes. The cashier will give you Argentine peso for spare change. Coto supermarket often gives a higher rate than the actual rate.

Top-up credit card

There are debit Mastercard- or Visa cards available such as Revolut. It is a top-up debit card. Revolut, for example, uses the interbank rate that fluctuates during the day without any fee. A good way for travelers and residents without an Argentinian bank account. Check out more on their website.

Paying tours or other events

The difference between the official exchange rate and the black exchange rate is of course not unknown to tourist companies such as tours, shows, etc.

You can certainly pay in Argentine pesos at the cash register, but you will regularly be asked to pay this at the black exchange rate. For example, a ticket will cost you $50. Initially, you would think that you have to pay 5,000 ARS. So 25 USD if you exchanged your money on the black market. But they will then ask to pay 10,000 ARS at the black exchange rate.

So you don’t actually make a profit on this.

You will make a profit on restaurant visits, government museums and local shops. I have noticed that gift shops have increased the prices in Argentine pesos so that you actually continue to pay the same in USD.

Extra tip!

Have some cash with you. I mentioned that stores have to accept credit/debit card payments by law, however, not every store is happy with it. Also when a store accepts card payments, it’s common that they will make a difference between paying cash or with a card. They will put two prices on the price tag. One in cash (cheaper) and one for card payments.
