Opening a bank or fintech account in Mexico City

A plain-English rundown of how banking and payments work in Mexico City, Mexico — 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 Mexico City.

Regulator

Banco de México / CNBV

Financial technology institutions (ITFs) in Mexico must be registered with the CNBV under the Fintech Law. Check the CNBV registry before a provider holds your pesos.

Currency

Mexican peso (MXN)

Local accounts and everyday payments in Mexico City are denominated in Mexican peso (MXN). Providers may also let you hold other currencies, but domestic transfers settle in MXN.

Account format

How accounts are addressed

Mexican interbank transfers are addressed with an 18-character CLABE (bank code, branch, account, and a check digit); a SPEI payment can also target a phone number or alias registered to the account.

Payments & transfers

Moving money locally

SPEI is Mexico's instant interbank system, available 24/7 with per-transaction limits set by each bank; STP is a private rail some fintechs use instead. Timing follows your provider.
