Calculator
The blue dollar (dólar blue) is the US dollar traded on Argentina's informal market: unlicensed exchange houses known as cuevas and street dealers known as arbolitos, concentrated in downtown Buenos Aires. There is no quota, no registration and no bank in between, so the price is what people will actually pay for a cash dollar.
Buy and sell. The buy rate (compra) is what a dealer pays you for your dollars; the sell rate (venta) is what you pay to buy dollars. If you are changing dollars into pesos, look at the buy rate. The spread between the two, usually around twenty pesos, is the dealer's margin. This is the Buenos Aires rate; in Córdoba, Rosario, Mendoza or Salta the blue runs a few pesos higher, and small amounts get a worse price.
Weekends and public holidays bring no new quote: the last business day's close stands. The crypto dollar trades around the clock and is what people watch while the blue is closed.
Travellers and remittances. Foreign Visa and Mastercard purchases in Argentina settle close to the MEP dollar, which sits near the blue, so paying by card is no longer the trap it once was. Cash changed at the blue rate still gets slightly more pesos; bring clean 100-dollar bills, small and worn notes get less. Money sent through Western Union is paid out at a rate that follows the CCL dollar with a lag.
Frequently asked questions
What is the blue dollar rate today?
Today, 5 September, the blue dollar sells at ARS 1,540 and buys at ARS 1,520 (updated 22:02).
What is the difference between the buy and the sell rate?
The buy rate is what you receive per dollar you sell; the sell rate is what you pay per dollar you buy. The sell rate is always the higher of the two.
Why is the blue rate different from the official rate?
The official rate is the regulated price at which banks sell dollars (ARS 1,529.40 today); the blue rate is the free price of the informal market. When buying at the bank is restricted, the blue detaches upwards; when it is not, the two converge. The difference is the exchange-rate gap, +0.7% today.
Is the blue dollar legal?
Holding dollars is legal in Argentina. Buying or selling them outside the regulated market is not authorised: it is the informal transaction that falls outside the law, not the holding. This site reports the reference rate; it does not buy or sell currency, nor point to anyone who does.
Should I use cash or a card as a tourist?
Foreign cards are settled near the MEP rate, which sits close to the blue. Cash changed at the blue rate still yields a few more pesos per dollar, but you carry the risk and the hassle. Compare the two rates on this page on the day.
