What is the Monto Transaccional del Usuario (MTU)?

The Monto Transaccional del Usuario, or MTU, is a new regulation implemented by the Comisión Nacional Bancaria y de Valores (CNBV) on October 1st. This measure aims to enhance the security of your digital banking by adding an extra layer of protection to your money transfers.

Who is Affected by the MTU?

All individual users are required to set a transfer limit for their transactions through mobile banking apps or online banking platforms when sending money to third-party accounts, such as family, friends, and service providers.

Why is the MTU Important?

The MTU serves as a safeguard against unauthorized transactions and potential fraud. By setting a personalized transfer limit, users can control the maximum amount they are willing to send in a single transaction, thereby minimizing risks associated with digital banking.

How to Change Your MTU

If you haven’t already adjusted your MTU and your bank has set it for you, there’s still an opportunity to establish a limit that suits your needs. Here’s how:

  1. Log in to your mobile banking app or online banking platform.
  2. Navigate to the settings or profile section.
  3. Look for the MTU option and adjust the limit according to your preferences.
  4. Save your changes and confirm the new MTU.
