Just looked at the latest ranking of largest banks in Brazil and honestly, the shift is pretty interesting. Nubank is sitting at the top with 391 billion, which is wild considering where they started. Itaú's still massive at 314 billion, followed by Bradesco and BB in the 130-140 billion range. Santander holding strong at 96 billion, then you've got BTG pushing 131 billion.

What caught my eye though is how the mid-tier banks are structured. Inter at 15 billion, Banco Pan at 9.6 billion, and Amazônia rounding out the list at 5.2 billion. The gap between the top players and everyone else is pretty significant. If you're tracking the financial sector in Brazil, these largest banks in Brazil basically control the market landscape right now. Interesting times for fintech disruption vs traditional banking.
