Adding a current snapshot for anyone reading this later (Nov 2026). Rates on 7 Nov, 9:00 (dolarapi), pesos per USD: official 1,520 buy / 1,570 sell, blue 1,535 / 1,555, MEP 1,560 / 1,588. With blue and official this close, there is little reason to hunt for special cash deals: a foreign card for daily spending, some clean USD notes for a casa de cambio, and a Western Union transfer to yourself as a backup cover most situations. If you move money in crypto, USDT to pesos is quoted by exchangers at roughly 1,530 to 1,600 right now, so get two or three quotes and confirm the final amount before handing anything over. Disclosure: I work on ArgHub, a directory of exchanger quotes.
