This ranking is for LATAM-incorporated businesses opening a first or replacement operating account: Brazilian MEIs and Simples Nacional businesses (the largest LATAM SMB segment by count, ~21M MEIs registered as of 2026) needing free PIX-native accounts with FGC-protected deposit insurance; LTDA / SLU limited companies in Brazil serving the broader SME tier; marketplace sellers on Mercado Livre / Mercado Libre across BR / AR / MX / CO / CL where the platform-receivables integration is structural; physical retail businesses needing card-acceptance terminals (Point, Stone) for in-person sales; and cross-LATAM operators with active presence in 2+ LATAM markets needing local-currency rails per country.
The structural decision in BR specifically is the same in every case: full BACEN financial institution vs payment institution. Nubank PJ (via Nu Financeira S.A.), Inter Empresas, C6 Bank, and Banco PAN all hold BACEN financial-institution licences — customer deposits in interest-bearing products carry FGC cover up to BRL 250,000 per institution per holder. Mercado Pago Empresas (Mercado Pago Pagamentos S.A.) and Cora / BHub operate as BACEN payment institutions — funds segregated under payment-institution rules but NOT FGC-protected. The trade-off matters above BRL 50K. Outside BR, the same structural pattern applies across AR / MX / CO / CL with different national-level regulators (BCRA, CNBV, SFC, CMF).
