Why money in Argentina is complicated
Argentina is one of the few countries where a traveler can't just grab a bank card and forget about cash. The official currency is the Argentine peso (ARS), but due to decades of inflation, the US dollar has become a de facto parallel currency. Hotels and excursions often price in dollars, while supermarket shelves show pesos. Without understanding the local financial system, you can lose 20–30% of your budget on unfavorable exchanges.
All prices and exchange rates in this article are approximate for 2026. Argentina lives under high inflation, so specific numbers change every month. The principles and strategies remain current.
Official rate and blue dollar
Historically, Argentina has had two dollar exchange rates: the official rate (tipo de cambio oficial) and the parallel rate, known as the "blue dollar" (dólar blue). The official rate is set by the Central Bank, while the blue dollar is the free-market rate at which Argentines buy and sell dollars unofficially.
The gap between rates has at times exceeded 100%. In 2025–2026, the government took steps to unify the currency market, and the difference has narrowed substantially. Nevertheless, checking the current rate before your trip is mandatory.
Where to check rates: sites like dolarito.ar or dolarhoy.com show both rates in real time.
Comparing currency exchange methods
| Method | Rate | Fee | Limit | Convenience | Overall value |
|---|---|---|---|---|---|
| Casa de cambio (exchange house) | Market / close to blue | 0–1% | None | High | Best |
| Western Union | Market | 0% on transfer | Depends on transfer | Medium | Good |
| ATM | Official | 10–15% per withdrawal | $200–300 per transaction | High | Poor |
| Bank card (payment) | Official | 3–5% bank conversion | None | Very high | Poor |
| Airport exchange | Worst | 3–5% | None | Very high | Worst |
Best strategy: cash dollars
The optimal approach for a traveler is to bring US dollars in cash and exchange small amounts at casas de cambio as needed.
Why this works:
- You get the market rate, not the deflated official rate
- No ATM fees (which run 10–15% per withdrawal)
- You control how much to exchange, and you won't end up with a pile of depreciating pesos before departure
Practical tips:
- Bring bills of $50 and up—smaller denominations may get a worse rate
- Bills must be in good condition, without marks or damage. Argentine exchange houses are picky about dollar quality
- Old bills (small head) are accepted, but sometimes at a slightly less favorable rate
- Don't exchange everything at once—inflation works fast, pesos lose value every week
Where to exchange dollars for pesos in Ushuaia?
Exchange houses are concentrated on the main pedestrian street, San Martín: look for signs reading Casa de Cambio or Cambio. They're open from 9:00 a.m. to 5:00 p.m. on weekdays and until 1:00 p.m. on Saturdays; most are closed on Sundays. Don't exchange at the airport—the rate is substantially worse. Arrived in the evening? Exchange the minimum for a taxi, then handle the rest in town the next day.
There's an exchange booth at Ushuaia airport, but the rate is substantially worse. If you arrive in the evening or on a weekend, exchange a minimal amount at the airport for a taxi, and do the bulk in town the next day.
Bank cards
Visa and Mastercard are accepted at most restaurants, hotels, and major stores. But there are quirks:
- Conversion happens at the official rate, which is less favorable
- Your bank may add a fee for international transactions (1–3%)
- Small shops, kiosks, and taxis work with cash only
- Entry to Tierra del Fuego National Park is paid exclusively in cash pesos
It's worth having a card as a backup, but cover main expenses with cash.
ATMs (cajeros automáticos)
In Argentina, there are two ATM networks: Banelco and Link. Both work with international cards, but the conditions are inconvenient:
- Withdrawal limit per transaction—equivalent of $200–300 (in pesos)
- ATM fee—10–15% of the withdrawal amount
- Plus your bank's fee for international withdrawal
- Conversion at the official rate
In total, you lose 15–25% compared to exchanging cash at a casa de cambio. ATMs are an option only as a last resort.
Tipping and small expenses
Tipping is customary in Argentina:
- Restaurants: 10% of the bill. Leave tips in cash, even if paying by card
- Taxis: round up to the nearest convenient amount
- Guides: at your discretion, usually the equivalent of $5–10 per person for a day tour
- Hotels: $1–2 for help with luggage
National park entry
Tierra del Fuego National Park is a mandatory stop in Ushuaia. Entry is paid only in cash Argentine pesos. Cards are not accepted. The fee for foreigners is higher than for Argentines, and it's revised every season.
VAT refund (IVA)
Argentina's VAT (IVA) is 21%. Foreign travelers can get a partial tax refund on purchases at stores participating in the Tax Free program. Conditions:
- Purchase must exceed the minimum amount (check the current threshold)
- Store must participate in the program and issue a special receipt
- Refund is processed at the airport before departure, at a Global Blue or similar operator desk
- You must present the goods at customs
In practice, the program mostly works in Buenos Aires. In Ushuaia, there are fewer participating stores.
Mercado Pago and digital payments
Mercado Pago is Argentina's equivalent of Apple Pay and Google Pay combined. It's used everywhere: from cafés to street vendors. However, registration requires an Argentine DNI (ID document) and a local bank account, so this method is unavailable to travelers.
Frequently asked questions
Can you pay directly in dollars?
In tourist spots—often yes: hotels, tour companies, and some restaurants accept dollars. But they'll give change in pesos, and the conversion rate may be unfavorable. Better to exchange dollars at a casa de cambio and pay in pesos.
How much cash should I bring?
Depends on trip length and travel style. For a week-long trip to Ushuaia for two, figure on $800–1,500 in cash on top of prepaid lodging and excursions. That'll cover food, transport, entry fees, and purchases.
Euros or dollars—which is better?
Dollars. Euros are accepted at exchange houses, but the rate is less favorable, and stores and restaurants won't take euros. If you only have euros—exchange them for dollars before the trip.
Is it safe to carry cash?
Ushuaia is one of Argentina's safest cities. Standard precautions: don't flash large sums, use the hotel safe, carry money in different places. In Buenos Aires, be more careful—use a money belt and don't pull out your wallet in view.
Do I need to declare currency on entry?
When bringing in amounts over $10,000 per person, you must fill out a customs declaration. Amounts below that threshold don't require declaration, but it's recommended to have proof of funds on hand in case of questions.
Does the exchange rate vary by city?
Yes, slightly. In Buenos Aires, the rate is usually a bit better than in Ushuaia, due to greater competition among exchange houses. The difference is typically 1–3%.
