If you're heading to Argentina and tempted to exchange dollars at the unofficial “blue dollar” rate, you’re not alone. The official exchange rate is often much worse than the street rate, and many travelers and locals go to the black market to get more pesos for their dollars. But what are the real risks—legally and in terms of personal safety? I’ll break down the actual dangers, share real experiences, quote experts, compare how Argentina handles this versus other countries, and give you a practical, honest guide to making the safest decisions.
The core issue is obvious: Argentina’s official dollar-to-peso rate is heavily controlled by the government, leading to a giant gap between what banks offer and what you can get on the street. For example, Bloomberg reported in March 2024 that the blue dollar was nearly double the official rate. That’s a huge incentive to seek out unofficial exchanges. But, as someone who's actually tried both, the risks are real and not always obvious.
Let me walk you through what actually happens—and what could go wrong.
It's hard to miss: walk down Florida Street in downtown Buenos Aires, and you'll hear the word “cambio, cambio!” whispered by dozens of “arbolitos” (street money changers). It feels sketchy, sure, but it’s the daily reality for locals and tourists alike.
My first attempt was a mess. I brought $100 in crisp bills, got nervous, and almost walked away when the guy leading me into a side alley asked if I wanted to “see the rate.” That’s your first clue: there’s no visible board, no receipt, and definitely no regulation. Sometimes you pass your cash, they count it, and hand you a stack of pesos. Sometimes they disappear for a minute “to get change.” And, yes, I’ve heard stories of people losing their entire amount.
Here’s a quick breakdown of how it typically works—and the mistakes I (and others) have made:
Sounds simple, but the risks ramp up fast. Let’s dig into what those risks actually are—legally and in terms of safety.
Exchanging money outside of official channels is technically illegal in Argentina. According to Law 19.359 (Penal Law of Exchange Offenses), unauthorized currency trading is a criminal offense. Penalties can include fines and, for repeat or large-scale offenders, even jail time.
For tourists, the risk of arrest is low, but not zero. Most enforcement is targeted at large-scale operations, not casual users. However, there have been rare crackdowns. According to a 2021 La Nación report, police have raided dozens of “cuevas” (informal exchange shops) and sometimes questioned customers.
What does this mean for you? If you’re caught in a police raid, you could have your money confiscated, be detained for questioning, and—at minimum—deal with a very stressful situation. I’ve never personally been stopped, but met a Canadian traveler who was caught up in a sweep; he lost $200 and spent five hours at the station before being released.
Remember: using “cuevas” (backroom exchange houses) can carry a slightly higher risk than street exchanges, since authorities target them more aggressively.
Let’s be blunt: exchanging large sums of cash on the street, in a foreign country, with strangers, is inherently risky. Most exchanges go smoothly—but when things go wrong, they go very wrong.
Here’s what can happen, based on both personal experience and what’s reported in local forums like TripAdvisor and Reddit:
One time, I was approached by a well-dressed young man offering a great rate. He led me into a tiny electronics store—then his “friend” tried to switch the bills. Thankfully, I double-checked before leaving. In hindsight, I should have insisted on staying in public.
Locals recommend never exchanging more than $100 at a time, always checking notes under good light, and using a UV flashlight (seriously, people do this!). I started carrying one after a particularly bad experience.
In 2022, an Australian expat posted his story on Expat.com about losing $500 in a fake “cueva.” He went with a friend, handed over cash, and received a mix of real and counterfeit bills. By the time he realized, the “cave” was closed and the arbolito was nowhere to be found. Local police took a report but said there was little they could do.
These stories aren’t rare. And because the trade is illegal, you have no legal recourse if something goes wrong.
Here’s how Argentina’s approach to “verified trade” in currency contrasts with other major countries:
| Country | Legal Currency Exchange Standard | Law/Regulation | Enforcement Agency |
|---|---|---|---|
| Argentina | Official channels only; black market illegal | Law 19.359 | Central Bank, Police |
| United States | Currency exchange must be licensed; black market rare | FinCEN MSB Laws | FinCEN, State Regulators |
| UK | Currency exchange must be FCA-authorized | FCA Rules | Financial Conduct Authority |
| EU (France, Germany) | Regulated, only banks and licensed bureaux | OECD AML Guide | Central Banks, Police |
As you can see, most developed countries have strict, transparent regulations—making “black market” exchanges practically non-existent. Argentina’s black market exists mainly because of heavy government controls and currency instability.
As trade lawyer Dr. Ana Ferrero said in a BBC interview, “The gap between the official and unofficial rates invites risk, but also creates a parallel economy that’s impossible to regulate fully.” That’s the paradox: you get a better rate, but lose legal protection.
If you’re going to use the black market anyway (and many do), here’s what actually works, according to both locals and travelers:
I wish someone had told me to use Western Union for larger transfers. The rates are close to the blue dollar, and you can pick up cash at official locations, with security.
So, is using the black market for currency exchange in Argentina worth the risk? If you want the best rate, yes—but you’re giving up legal protection and risking personal safety. Most travelers do it anyway, but go in knowing the risks and always take basic precautions.
Personally, after a few close calls and one bad counterfeit experience, I switched to using Western Union for anything over $100. For small amounts, I still use arbolitos—but only in broad daylight, in public spaces, and after checking every bill.
Next steps: If you’re planning to travel, check the current blue dollar rate, talk to locals for recommendations, and always have a backup plan in case something goes wrong.

The street exchange scene in Argentina is wild, unpredictable, and, yes, a bit thrilling. But don’t let the thrill outweigh your common sense.
