Latin America’s best retail bank 2026: Santander

Increasingly, Santander is leveraging global scale by focusing on and investing in global businesses – including those in retail banking. Latin America has been central to these efforts and it has seen the benefit.

It was a pivotal year for Gravity, the bank’s in-house core banking cloud technology enabling post-mainframe migration. Starting with Chile, the bank then integrated Gravity in Mexico in 2025, before moving onto Brazil in 2026. This has put Santander in a fundamentally better position as a retail bank in Latin America.

Mexico is a good example of how technological transformation and an early move to the cloud has helped it increase its deposit base ahead of the market, without additional costs.
