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. It is the exchange rate Argentines mean when they say "the dollar went up", and the one a visitor to Argentina should know before changing money.
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: three ways to get pesos, and the winner changes. Cash dollars at a cueva get the blue buy rate; bring clean 100-dollar bills, small and worn notes get less. A foreign Visa or Mastercard settles near the MEP dollar, so paying by card is no longer the trap it once was. And you can send dollars to yourself through Western Union and pick up pesos in cash at an agent, at a rate that follows the CCL with a lag of up to two days. None of the three is always best: compare them on the day.
Frequently asked questions
What is the blue dollar rate today?
Today the blue dollar sells at ARS 1,565 and buys at ARS 1,545 (updated ).
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 1,545.54 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, +1.3% 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.
Cash, card or Western Union: which gives a tourist the most pesos?
It changes from day to day, so it is a game between three rates. Cash dollars changed at a cueva get the blue buy rate (ARS 1,545 today). A foreign card settles near the MEP (ARS 1,550.45). Sending dollars to yourself through Western Union and picking up pesos in cash at an agent pays near the CCL (ARS 1,632.25), with a lag of up to two days. Whichever is highest that day wins, and Western Union wins more often than people expect.
