A decade ago, Nubank was a credit card start-up operating out of São Paulo. Today, at $16.3 billion in retail banking revenue (2025), it has surpassed HSBC and Standard Chartered’s global retail banking businesses and is on track to overtake Itaú Unibanco in Brazil in 2026 and Citigroup by 2027. What is emerging is not just rapid growth, but the early stages of a long-term strategy to build a global retail banking franchise.

Digital banks serve customers far more cheaply than incumbents, but most generate less revenue for every dollar spent on servicing. Nubank and WeBank stand out, generating 4.1x and 3.8x their servicing cost in revenue respectively, outperforming leading incumbents. Most other digital banks fall short of incumbent benchmarks, showing that lower cost-to-serve alone does not guarantee stronger economics.
