2 of the exchanges we recommend in Mexico take SPEI for funding bitcoin purchases. It is the rail local buyers lead with, so it is usually the cheapest and fastest way in.
What is SPEI?
SPEI, the Sistema de Pagos Electronicos Interbancarios, is Mexico's interbank electronic transfer system, administered and operated by Banco de Mexico. Banks, brokerages and other regulated institutions use it to move pesos between accounts held at different institutions, and it is the rail behind an ordinary peso transfer sent from a Mexican banking app. Mexican exchanges use it for peso deposits and withdrawals.
- Speed
- Banxico's SPEI rules require a receiving bank to credit a low value transfer within five seconds, at any hour on any day, with a thirty second limit for other participants during the 06:00 to 18:00 window on banking days.
- Cost
- Banco de Mexico charges participating institutions a fixed fee plus a per transaction fee, so what you pay is whatever your own bank sets in its published tariff.
- Limits
- SPEI carries both small and large value transfers, so the per transaction and daily caps you run into are set by your own bank rather than by the scheme.

Do you need a VPN?
A VPN hides which sites you visit from the network you are on and from your internet provider, which is worth having when you move money over a connection you do not control. It does not get you past an exchange's identity checks: every platform we list verifies who you are no matter where you connect from.
If you want one, the strongest records on our list belong to NordVPN (6 independent no-logs audits, the most of any service we review), Windscribe (its no-logs claim tested in the real world 3 times) and Proton VPN (the most audited service with a free tier).

Frequently asked questions
Which exchanges accept SPEI in Mexico?
Of the 5 exchanges we recommend in Mexico, Binance and Coinmama accept SPEI for funding purchases.
Is buying bitcoin with SPEI legal in Mexico?
Bitcoin is legal for individuals and businesses in Mexico, governed since 2018 by the Fintech Law, whose Article 30 states that virtual assets are not legal tender. Banco de Mexico's Circular 4/2019 bars banks and regulated fintech institutions from offering crypto services to their clients, so the market runs through dedicated crypto platforms rather than banks. The CNBV handles financial licensing and the tax authority expects gains to be declared.
How long does a SPEI deposit take?
Banxico's SPEI rules require a receiving bank to credit a low value transfer within five seconds, at any hour on any day, with a thirty second limit for other participants during the 06:00 to 18:00 window on banking days. That is the rail itself; an exchange may hold a first deposit for longer while it verifies your account.
What does it cost to buy bitcoin with SPEI?
Banco de Mexico charges participating institutions a fixed fee plus a per transaction fee, so what you pay is whatever your own bank sets in its published tariff. Any fee the exchange adds on top is separate, and is shown per exchange above.
