Latin American neobanks expand operations
Nubank has overtaken traditional banks to become Brazil’s largest private financial provider by customer numbers after a decade of expansion. The neobank now holds accounts for nearly 60% of Brazilian adults, making it the country’s largest private financial institution by customer count, while half of all banked Brazilians use digital banks or fintech platforms as their primary financial service, according to the Central Bank of Brazil and research from Instituto Locomotiva.
This shift reflects a broader transformation in consumer behavior, where fintechs have transitioned from disruptors to central players in the banking ecosystem. Álvaro Machado Dias, associate director of Instituto Locomotiva, notes that “the fintech market has decidedly moved beyond access and into becoming the central piece of the Brazilian banking economy, also from the population’s perspective.” This development signals a major shift in Latin America, where fintechs are now seeking full banking licenses to transition from challengers to direct competitors of established institutions.
Digital banks have already transformed consumer behavior across the region. In Brazil, 61% of adults and 47% of Mexicans used mobile devices for their most recent retail transaction, per industry data. Argentina’s digital wallets now surpass cash usage, with 70% of consumers relying on them over the past six months compared to 52% for physical money, according to Mastercard. Mexico’s Nu Mexico reached 15% market penetration just seven years after launch, while Mercado Pago, the fintech arm of now-Montevideo-headquartered MercadoLibre, now serves 83 million monthly active users across eight countries—a 29% increase year-over-year. The rapid adoption shows how digital-first institutions have reshaped financial interactions, particularly in markets where traditional banking infrastructure remains underdeveloped.
Fintechs Push for Full Banking Licenses
The next critical step involves regulatory approval to convert these customer bases into full banking operations. Nubank finalized an agreement in July to acquire Banco Porto Real de Investimentos S/A, granting it a Brazilian banking license. Its Mexican unit began operating as a bank last month, becoming the first Mexican SOFIPO (popular financial society) authorized to convert.
Mercado Pago is also pursuing a Mexican banking license with an ambition to build the country’s largest digital bank, with its application reportedly first in line at Mexico’s banking regulator. Plata obtained its license in February, and Ualá Bank already holds full licenses in Argentina, Mexico, and a financing license in Colombia. These moves mark a deliberate strategy to align fintechs with the regulatory and economic frameworks of traditional banks, ensuring they can operate at scale.

Regulatory changes create clear financial advantages. Mexico’s SOFIPO framework caps deposit insurance at 25,000 UDIs, but full banking licenses eliminate this limit and provide sixteenfold greater protection. Banks with licenses gain access to payroll accounts, currently held by only about a third of Mexican adults and dominated by four legacy institutions. Most important, full licenses enable cheaper funding through deposits, a necessity as fintechs expand their loan portfolios. Nu Mexico already holds $5.9 billion in deposits, making scalable lending operations a priority. The ability to accumulate and deploy deposits efficiently will be critical as these institutions grow their credit offerings, reducing reliance on higher-cost alternative funding sources.
Capital and Tech Drive the New Era
Reginaldo Nogueira, national director of Brazil’s Ibmec business school, said that once a digital bank holds the same license, follows the same rules, and funds itself the same way, it stops being essentially different from a traditional bank. The difference shifts to technology, efficiency, and customer experience. The transition demands substantial investment, but Nubank founder David Vélez has pledged $4.2 billion for Mexico through 2030, part of a broader strategy to replicate Brazil’s success in other markets. This commitment reflects the scale of capital required to bridge the gap between fintech agility and the operational demands of full banking, while maintaining the innovation that drove their initial growth.
This evolution reflects a broader industry shift. Fintechs that once operated under lightweight licenses now face growing constraints as they scale. Limits on deposit insurance, restricted account types, and higher funding costs create obstacles precisely when they need capital to accelerate growth. The solution is clear: secure banking licenses, attract deposits, and compete on equal terms with traditional banks—while retaining the technological advantages that defined their initial success. This shift represents a reversal from a decade ago, when fintechs were outsiders challenging established banks for control of customers and balance sheets. Today, they have secured the customer base and now seek the regulatory privileges that underpin the banking business itself.
Consumer Experience Meets Banking Reality
For consumers, the immediate impact may be modest. Digital banks will continue emphasizing mobile apps and seamless experiences, but their infrastructure will now align with that of traditional institutions. The challenge will be whether fintechs can balance their customer-focused approach with the operational demands of full banking.
Nubank’s expansion into full banking operations in Brazil and Mexico demonstrates the scale of this transition. The company’s $4.2 billion commitment to Mexico shows its ambition to replicate its Brazilian model elsewhere. With digital adoption already high across Latin America, the stage is set for a permanent shift in how financial services are delivered. The region’s fintechs have already proven their ability to attract customers; the next challenge is to translate that success into the stability and scale of full banking operations.
