Banking in Mexico for Foreigners 2026

Key Figures

Banking System Overview

Mexico's banking system is regulated by CNBV (Comisión Nacional Bancaria y de Valores) and Banco de México (Banxico). Deposits are insured by IPAB (Instituto para la Protección al Ahorro Bancario) up to 400,000 UDI (~USD 140,000) per depositor per bank.

The market breaks into three segments: large international banks (BBVA, Santander, HSBC, Citibanamex), large national banks (Banorte, BanBajío, Banregio), and digital banks / neobanks (Nu México, Hey Banco, Klar, Stori). All are licensed by CNBV and must comply with FATF requirements on anti-money-laundering (AML) and know-your-customer (KYC).

For expats, the standout fact is that several banks (Nu México, Hey Banco) allow fully remote account opening — just a passport and CURP, no income statements, no branch visit. Traditional banks generally require in-person visits and a broader document set.

Major Banks

BBVA México is the country's largest bank by customer count and assets. It offers a wide product range: current accounts (Cuenta Azul — free with a qualifying deposit, Cuenta Clásica — MXN 320/month), credit cards, mortgages, and investment products. The BBVA app is well regarded. Branch account opening for foreigners requires a CURP and proof of address.

Santander México is the second largest, with a strong network in Mexico City and major cities. It offers individual packages (Cuenta Online — free under balance conditions). It is known as relatively open to clients with foreign documents, provided they have a CURP.

Banorte is the largest bank of Mexican (domestic) origin. It is particularly strong in regions outside CDMX, and offers current accounts, credit cards, and mortgages. Requirements for foreigners are similar to other major banks.

Citibanamex (historically Banamex, Mexico's second-oldest bank) is in restructuring — Citigroup is selling the retail business. Access for new retail customers may be limited during the transition in 2026.

HSBC México is an international bank with good global transfer integration, useful for expats. The Advance package targets higher-income clients.

Digital Banks (Neobanks)

Nu México is the Mexican subsidiary of Brazilian Nubank, Latin America's largest digital bank. It offers a free current account (Cuenta Nu) with a competitive interest rate on the balance (~10–12% p.a. on small amounts via a CETES-linked product), a credit card, and small personal loans. Opening is entirely through the app; you need a passport and CURP. No monthly fees and no minimum balance.

Hey Banco (a BBVA subsidiary) is a digital bank focused on savings products, offering rates above traditional banks. Online opening with CURP.

Klar is a Mexican neobank targeting young people and those building a credit history. It offers a credit card with no monthly fee. Requires a CURP.

Stori is another neobank focused on credit cards for people with limited credit history — useful for foreigners starting to build a Mexican credit score from zero.

Opening an Account as a Foreigner

The required documents vary by bank, but the standard list for a foreigner includes: a valid passport, CURP (free, obtainable online via RENAPO), proof of address in Mexico (comprobante de domicilio — a utility bill for electricity, water, or gas, or a lease agreement less than 3 months old), and sometimes an RFC and/or immigration document (tarjeta de residencia).

The optimal strategy for a newly arrived expat: first open a Nu México account through the app (only passport + CURP required), giving you a Mexican account and debit card within a few days. Simultaneously, obtain CURP via the RENAPO website and — if needed — an RFC through SAT. Once those are in hand, open an account at a traditional bank if required.

Most traditional banks require in-person branch visits. Booking online or through the bank app usually reduces waiting time. Staff in branches in major cities (CDMX, Guadalajara, Monterrey) often speak English.

CURP and RFC: Key Identifiers

CURP (Clave Única de Registro de Población) is an 18-character unique code assigned to every person registered in Mexico's RENAPO database. Foreigners can obtain a CURP if they entered Mexico officially: via the form at gob.mx/curp or at a RENAPO office (and some INM offices). For tourists, a CURP is automatically generated from the FMM immigration card data at the border — check it on the website. CURP is free and does not require residency.

RFC (Registro Federal de Contribuyentes) is the tax identifier assigned by SAT (Servicio de Administración Tributaria), equivalent to a tax ID number. For foreigners, an RFC is required for formal employment, self-employment, tax filing, issuing CFDI invoices, and certain banking products (mortgage, some accounts). Without residency, obtaining an RFC is harder — it generally requires a personal visit to an SAT office with immigration documents.

Practical sequence: (1) get CURP online immediately on arrival; (2) use CURP to open Nu México or Hey Banco; (3) obtain RFC after securing residency and registering with SAT; (4) update your bank details once the RFC is ready.

Fees & Charges

Traditional banks charge a monthly maintenance fee unless conditions are met (minimum balance, card spend, etc.). Digital banks are generally entirely free. Interbank transfers within Mexico use the SPEI system (Sistema de Pagos Electrónicos Interbancarios): SPEI transfers are free for individuals at most banks.

International incoming transfers attract a receiving fee and, in some cases, a conversion spread. For large inflows from abroad, confirm the bank's SWIFT/BIC codes and terms for receiving foreign transfers — not all banks process them equally fast.

International Transfers to Mexico

Mexico is one of the world's largest recipients of remittances: in 2024, the total exceeded $63 billion, according to Banxico. Most transfers arrive from the US via Western Union, MoneyGram, and fintech payment services.

For expats, the most convenient options are: Wise (TransferWise) — low fees, transparent exchange rate, transfers in MXN to a Mexican account; Remitly — popular for transfers from the US/Canada to Mexico; PayPal — available but the exchange rate is less competitive; direct SWIFT bank transfer — works but takes 1–3 business days and may include a hidden spread.

Receiving large transfers (equivalent to $10,000 or more) will trigger the bank's AML checks under Mexico's anti-money-laundering law (Ley Anti-Lavado). Have supporting documents ready: bank statements, property sale agreement, or other proof of source.
