Is using the blue dollar rate legal?

It operates in a legal gray area. While not technically legal, it's widely practiced and tolerated. Tourists regularly use it without issues, but exchange reasonable amounts and use common sense.

Why won't my $20 bills get a good rate?

Smaller denominations are harder for money changers to move and store. $100 bills are preferred and get the best rates. $50s get slightly worse rates, and anything smaller gets significantly worse rates.

What if I can't find money changers on Florida Street?

Try asking at your accommodation for trusted contacts, use Western Union locations, or head to other tourist areas like San Telmo or Palermo where hostels often have connections.

Should I use ATMs in Argentina?

Only for emergency small amounts. ATMs give you pesos at the terrible official rate and charge high fees. Your purchasing power is cut in half compared to blue dollar exchanges.

How to Exchange Money in Argentina Using the Blue Dollar Rate

Exchange USD cash at unofficial exchange houses (cuevas) or through trusted contacts to get the blue dollar rate, which is typically 50-100% higher than the official rate. Bring crisp $100 bills for the best rates and avoid banks or ATMs for currency exchange.

Bring USD cash in $100 bills. Pack crisp, new $100 bills without any tears, marks, or folds. Smaller denominations get worse rates. Old or damaged bills may be rejected entirely. Avoid $50s and smaller bills.
Check the current blue dollar rate. Use DolarBlue.net or DolarHoy.com to check the current blue dollar rate (dólar blue). The rate changes daily. Screenshot the rate on your phone to reference during exchanges.
Find exchange locations in Buenos Aires. Head to Florida Street (Calle Florida) near the intersection with Corrientes or Lavalle. Look for people quietly saying 'cambio' or 'dólares.' Alternatively, ask at hostels or hotels for trusted contacts.
Negotiate and verify the rate. Quote the blue rate you found online. They may offer slightly less (1-3% below blue rate). Count the pesos carefully before handing over dollars. Use a calculator to verify the math.
Complete the exchange safely. Exchange in busy, public areas during daylight. Never follow someone to a back room. Count your pesos twice and put them away immediately. Keep exchanges under $500 USD per transaction.
Use Western Union as backup. Western Union locations offer rates close to blue dollar (usually 5-10% less). Send money to yourself from the app. Safer but requires more paperwork and slightly worse rates.
