Navigating money, exchange rates, and payment methods in Argentina used to be one of the most confusing parts of planning a trip to Buenos Aires. Fortunately, recent financial regulations and the widespread implementation of the Foreign Tourist MEP Exchange Rate have made spending money in Buenos Aires simpler and significantly more transparent than ever before.
Quick Money Summary for Buenos Aires
- Currency: Argentine Peso (ARS - $).
- Best Payment Method: Foreign Visa / Mastercard credit and debit cards (automatic MEP rate with zero hassle).
- Cash Backup: Keep a moderate amount of physical Argentine Pesos for small kiosks, taxis, and tipping (propina).
- Western Union: Excellent for sending money to yourself with higher cash exchange rates and zero card foreign transaction fees.
1. How the Foreign Tourist MEP Rate Works on Credit Cards
In the past, paying with a foreign credit card meant receiving the unfavorable official bank rate. Today, the Argentine Central Bank allows international credit and debit cards (Visa, Mastercard, American Express) to automatically process transactions at the MEP (Mercado Electrónico de Pagos) rate, which is virtually identical to the parallel Blue Dollar cash rate.
| Card Type | How It Works | Recommendation |
|---|---|---|
| Visa (Credit / Debit) | The transaction is converted directly at the MEP rate at the exact moment of purchase. Instant and frictionless. | Top Pick: Simplest and most transparent billing. |
| Mastercard (Credit / Debit) | Charges initially at the official rate, and within 2 to 5 business days deposits a direct statement credit/refund for the MEP difference. | Great: Reliable, though refunds appear a few days later on your statement. |
| Wise / Revolut / Nomad Cards | Accepted across 99% of POS terminals in Buenos Aires at the favorable MEP rate. | Excellent: Low foreign transaction fees and real-time app notifications. |
2. Cash vs. Card: What Should You Carry?
While cards and contactless payments (Apple Pay / Google Wallet) are widely accepted across restaurants, supermarkets, cocktail bars, and hotels in Palermo, Recoleta, and Puerto Madero, cash remains king in specific situations:
- Street Kiosks and Small Bakeries: Many small family-owned businesses or neighborhood bakeries prefer cash for purchases under $5,000 ARS.
- Traditional Taxis: While Uber and Cabify charge directly to your credit card, street yellow-and-black taxis often prefer cash (unless ordered through BA Taxi app).
- Tips (Propinas): In Argentina, tips cannot always be added to the credit card payment terminal. Carrying crisp 500, 1,000, or 2,000 ARS banknotes for tipping waitstaff is customary.
3. Western Union: Maximum Value for Cash Withdrawals
If you prefer carrying cash or want to fund large cash-only purchases (such as leather markets or antique fairs in San Telmo), using Western Union is the safest and most profitable method:
- Set up a Western Union account on the app before traveling.
- Send money from your bank account or debit card to yourself with pickup in Argentina.
- Collect your cash in person at major flagship branches (such as the branch on Av. Córdoba 1595 or Av. Santa Fe 3433) to ensure they have sufficient banknote reserves.
- Tip: Arrive early in the morning on weekdays to avoid long queues. Bring your original physical passport.
4. The "Blue Dollar" (Dólar Blue) and Money Changing
The informal cash exchange market still operates openly along the pedestrian walkway of Calle Florida in Microcentro (where street vendors announce «¡Cambio, cambio!») and in established financial exchange houses (cuevas). If you decide to exchange physical US Dollars or Euros:
- Bring $100 USD "Blue Band" Bills: The newest $100 bills with the blue security 3D ribbon receive the highest exchange rate. Worn, torn, or older small-head bills are often rejected or discounted by 5% to 10%.
- Inspect Banknotes for Counterfeits: Always verify watermarks, embossed texture, and color-shifting ink on 10,000 and 20,000 ARS bills.
5. Tipping Etiquette in Buenos Aires
Standard Tipping Rules (Propina)
- Restaurants & Cafes: 10% of the total bill is the standard custom for good service. (The "Cubierto" charge listed on some menus is a table-setting service fee and does not go to the waiter as a tip).
- Bars & Bartenders: $1,000 to $2,000 ARS per round or 10% of the tab.
- Taxis: Round up the fare to the nearest $500 or $1,000 ARS banknote.
- Hotel Porters & Tour Guides: $1,500 to $3,000 ARS per bag or $5,000+ ARS for a full-day guided walking tour.
