Context
With US$ 500 It is typical to make a monthly savings or separate silver for a trip: the difference between contributions is already seen in thousands of pesos. If you sell dollars to the bank you are paid the bid rate; If you buy, you pay the one to sell.
As a historical reference: a week ago (06/11) US$ 500 cost $ 785.000,00 (0,00%); a month ago, $ 767.500,00 (+2,28%); in the latter 30 days the range was of $ 765.000,00 a $ 785.000,00 (daily sales data from ArgentinaDatos.com).
Keep in mind: Buying at the official rate has been open to individuals since 2025, but each bank has its own price and some charge a fee.
The other way around? Passing pesos to official dollar.
