Detailed Narrative
AI-First Strategy and nuFormer Model
Nu Holdings is pursuing an "AI-first" vision, integrating foundation models into operations to create an AI-native banking interface. This strategy aims to enhance customer personalization, deliver contextual offers, and improve risk management by reducing credit and fraud losses. The company developed nuFormer, a proprietary model with 330 million parameters trained on 600 billion tokens, which has already led to a 3x improvement in credit performance compared to typical machine learning upgrades. This model enabled a major upgrade to credit card limit policies in Brazil, increasing limits for eligible customers while maintaining risk appetite.
Mexico's Rapid Scaling and Strategic Importance
Mexico has surpassed 13 million customers, reaching 14% of the adult population, and is now a key "S-curve" for Nu Holdings. ARPAC in Mexico has reached $12.50, nearing Brazil's levels, driven by strong credit card engagement and favorable unit economics. The cost to serve in Mexico is already below $1, outperforming Brazil at a similar stage. Management views Mexico as a market with significant long-term monetization potential, with a higher income per capita and a credit card market where 80% are revolvers.
Credit Portfolio Diversification and Risk Management
The credit portfolio reached $30.4 billion, up 42% YoY FX-neutral, with secured lending growing 133% and unsecured loans 63%. Secured and unsecured loans now represent 35% of total balances, up from 27% a year ago. This shift towards lower-risk segments, including public payroll loans, has strengthened overall portfolio quality. Despite a nominal NIM contraction, risk-adjusted net interest margins expanded to 9.9% due to lower credit loss allowance expenses, reflecting disciplined underwriting and improved recovery levels.
Deposit Franchise and Funding Cost Dynamics
Total deposits reached $38.8 billion, up 34% YoY FX-neutral. The overall cost of funding, expressed as a percentage of interbank rates, improved from 91% to 89%. However, dollar-wise interest expenses increased due to a deliberate strategy to offer more aggressive rates on segmented deposits (Money Boxes/Cajitas) in Brazil for primary banking relationship customers. This was partially offset by lower funding costs in Mexico and Colombia.
Efficiency and Profitability
The company achieved a record net income of $783 million and a 31% ROE, up 39% YoY FX-neutral. The efficiency ratio decreased to 27.7%, demonstrating continued progress in productivity and operating leverage. Management emphasizes strategic investments for long-term value creation, even if they create short-term cost pressures, with a clear trend of efficiency gains and margin expansion as the company scales.
