Banking in Argentina for Expats: Pesos and Dollars (2026)
Key Facts
—Residency helps a lot. Banking in Argentina for expats is far easier with a DNI and CUIL; without them, options are limited to some fintech apps or a CDI.
—Pesos and dollars. Residents can hold a peso account (caja de ahorro en pesos) and a separate dollar account, useful amid high inflation.
—Exchange controls. The ‘cepo’ currency controls shape how you buy and move dollars; the regime shifts, so check current rules.
—Fintech is big. Apps like Mercado Pago, Ualá and Brubank are widely used and quick to open.
—Documents. Banks typically want your DNI, CUIL or CUIT and proof of address.
Banking in Argentina for Expats: What You Need
For banking in Argentina for expats, residency is the dividing line. With a DNI and CUIL you can open standard bank accounts; without them, your realistic options are fintech wallets or limited arrangements using a CDI number.
Banks typically ask for your DNI, CUIL or CUIT and a proof of address.
Pesos, Dollars and Inflation
Because inflation has been high, locals manage money across currencies. Residents can hold a peso savings account and a separate dollar account, and many keep savings in dollars while spending in pesos.
Understand the difference between your everyday peso balance and dollar holdings before you start moving money.
Traditional Banks vs Fintech Apps
| Traditional banks | Fintech apps | |

| Best for | Salary, dollar accounts, full services | Everyday spending, transfers, QR |

Opening the Account
Resident accounts are opened in branch with your DNI, CUIL/CUIT and proof of address; you leave with a debit card and app access. Fintech apps onboard in minutes and are how many Argentines pay day to day.
Activate online banking and set transfer limits the same day.
Exchange Controls and Moving Money
The ‘cepo’ exchange-control regime governs how individuals buy and transfer dollars, and it changes with policy. For money from abroad, many expats use Western Union or services like Wise, comparing the effective rate against the official one.
Always check the current rules before large transfers, as limits and taxes shift.
Fees, Limits and Safety
Compare account maintenance fees and minimum balances, and remember peso balances lose value to inflation — which is why many residents keep savings in a dollar account or stable instruments.
Exchange-control limits on buying dollars change with policy; check the current monthly cap and any taxes before planning a large purchase or transfer.
Keep US-dollar cash for flexibility, use ATMs in secure locations, and treat Western Union as a reliable channel for money from abroad when the rate is favourable.
Tips and Limits
Keep some US-dollar cash for flexibility, watch account fees and minimums, and confirm a branch’s exact document requirements before you go, since they vary. Treat exchange-control rules as a moving target and verify before acting.
