Opening a bank or fintech account in Buenos Aires

A plain-English rundown of how banking and payments work in Buenos Aires, Argentina — the regulator to verify, the currency you'll transact in, how local accounts are addressed, and the rails that move your money. Treat these as the checks to make before you commit, not marketing.

The essentials

Four things worth confirming before you open or fund an account in Buenos Aires.

Regulator

Banco Central de la República Argentina (BCRA)

Banks and payment service providers in Argentina must be authorised by the BCRA, and fintech wallets operate under the BCRA's payment provider regime. Confirm authorisation before holding balances.

Currency

Argentine peso (ARS)

Local accounts and everyday payments in Buenos Aires are denominated in Argentine peso (ARS). Providers may also let you hold other currencies, but domestic transfers settle in ARS.

Account format

How accounts are addressed

Interbank transfers use the 22-digit CBU (Clave Bancaria Uniforme); digital wallets use the equivalent 22-digit CVU. Both identify the destination account for peso transfers.

Payments & transfers

Moving money locally

Transferencias 3.0 enables instant QR-based interbank and wallet transfers 24/7, while traditional transfers settle in batch windows. High inflation erodes peso balances quickly, so providers may offer USD-linked products.

Confirm the provider is licensed — check Banco Central de la República Argentina (BCRA) before you deposit money.
Expect to transact in Argentine peso (ARS) for anything domestic.
Have the correct account details to hand — the format above is what a local transfer needs.
