A peso charge lets your card handle conversion

Visa and Mastercard work at most shops, restaurants and hotels. A second card from another bank protects you against a fraud hold or lost wallet. When the terminal offers dollars, choose pesos: the dollar option is dynamic currency conversion, at a rate set by the merchant's provider with a markup.

An Argentine-issued card opens up shop discounts and interest-free installments (cuotas). Small shops may instead display a QR code for a wallet such as Mercado Pago, which requires a DNI. Until you have one, cash pesos fill that gap.

Cash has a cost, but it still has a place

Banelco and Red Link ATMs charge foreign cards per withdrawal, and your US bank may charge again. Fewer, larger withdrawals reduce fixed fees; an account that refunds ATM fees worldwide, such as Charles Schwab Investor Checking, removes most of that expense.

Banks and licensed exchange houses (casas de cambio) change clean, undamaged US$100 bills on presentation of a passport. The street blue-dollar rate is now close to the official rate, without the protections of a licensed counter. The largest peso note is ARS 20,000, about US$13. If you carry more than US$10,000 in cash, declare it to US Customs on departure using FinCEN Form 105 and to Argentine customs on arrival.

The local account comes after the DNI

Argentine banks generally open accounts for foreign residents with a DNI and either a CUIL, the work and social security number from ANSES, or a CUIT, the tax number from ARCA (formerly AFIP). A passport and tourist entry usually will not suffice. After residence is granted, a first DNI costs ARS 20,000 at a RENAPER appointment and arrives by mail in 2 to 6 weeks.

Banco Nación, Galicia, Santander and BBVA are large banks; Brubank is digital, while Mercado Pago and Ualá are widely used wallets. A standard bank package includes peso and dollar savings accounts (cajas de ahorro). Since April 2025, bank-app dollar purchases have no old US$200 monthly cap. A bank account has a 22-digit CBU, a wallet a CVU, and each can have a word alias for instant, free transfers between personal accounts. Rapipago and Pago Fácil counters also take cash payments for utility bills.

Your US account still does important work

A US checking account remains useful for income, card payments and wires to Argentina. Its login codes also need to reach you, often through a US number kept on a low-cost plan or eSIM. Some banks restrict services for customers with a foreign address; a US mailing arrangement with family or a forwarding service can keep correspondence accessible, while you should give the bank accurate residential details. An Argentine bank receiving a wire to your dollar account may ask where the savings came from, so the US statements matter.

An Argentine balance brings US reporting questions

An FBAR (FinCEN Form 114) is required if your foreign accounts together exceed US$10,000 at any point in the calendar year. It goes through FinCEN's BSA E-Filing system, apart from your tax return. The April 15 deadline has an automatic extension to October 15.

Form 8938 is attached to Form 1040. For taxpayers living abroad, its thresholds are above US$200,000 at year end or US$300,000 at any time, doubled for joint filers; it does not replace the FBAR. US citizens are taxed on worldwide income, including Argentine bank interest, and there is no US–Argentina income tax treaty.

The local account becomes most useful when bills and QR purchases begin to recur. Until your DNI arrives, a no-fee US card and a modest peso reserve cover most of the same daily ground.

Common questions

Can Americans open a bank account in Argentina?

Yes, once they have residence, a DNI and a CUIL or CUIT. With only a passport on a tourist entry, most Argentine banks will not open an account.

Should I pay in pesos or dollars at a card terminal?

Pesos. The dollar option lets the merchant's provider set the exchange rate and add a markup, which costs more than your card network's conversion.

Is the blue dollar still better than paying by card?

Rarely. Since April 2025 the gap between the blue rate and the official rate is small, and US cards convert close to the official or MEP rate (the legal rate for dollars bought through bond trades).

Do I have to report an Argentine bank account to the US?

Yes, on an FBAR if all your foreign accounts together pass US$10,000 at any point in the year. Form 8938 applies separately at higher thresholds.
