Does MercadoLibre's Expanding Credit Book Signal Mounting Risk Ahead?

Read MoreHide Full Article

Key Takeaways

  • MELI's rapid credit expansion is deepening user engagement but introducing new margin and risk pressures.
  • Credit cards are taking a larger share as funding costs climb and asset quality stays broadly stable.
  • Competition from SE and NU is intensifying, adding pressure on MELI's credit pricing and lending margins.

MercadoLibre’s (MELI - Free Report) lending arm has become a powerful driver of engagement inside Mercado Pago and its rapid expansion is shaping the company’s operating profile. The credit portfolio is scaling across its main markets as more users adopt the credit card and financing tools that tie payments, commerce and financial services together. This deeper integration is strengthening usage, but the speed of expansion brings its own set of margin and risk considerations.

In the third quarter of 2025, the total credit portfolio increased 83% year over year to $11 billion, with growth spread across consumer, merchant and asset-backed segments. Credit cards continue to account for a rising share of originations, shifting the mix toward longer-duration products. Net Interest Margin After Losses stood at 21%, easing sequentially as funding costs climbed sharply in Argentina, while asset quality remained broadly stable with 6.8% of loans between 15 and 90 days past due and 17.6% more than 90 days past due.

Fintech revenues continue to reflect this momentum. The Zacks Consensus Estimate for fourth-quarter 2025 fintech revenues is pegged at $3.63 billion, indicating a 45% year-over-year increase, suggesting that credit-driven revenue growth will remain robust even as the company absorbs higher provisioning and funding requirements associated with a larger book.

However, as the mix leans further into credit cards, new cohorts will take time to reach breakeven, keeping returns under pressure during issuance-heavy periods. The pace of loan expansion suggests that MELI’s growing credit book could introduce periods of margin strain even as engagement improves. The combination of longer-duration credit cards, rising funding costs and slower cohort maturity means lending may support revenue growth while still limiting profitability in the near term. Whether this expansion becomes a sustained advantage or a mounting risk will hinge on the company’s ability to keep spreads stable and asset quality intact.

MELI Faces Intense Competition

Competition is tightening for MELI as Sea Limited (SE - Free Report) and Nu Holdings (NU - Free Report) deepen their push into digital lending across Latin America. Sea Limited is scaling personal loans and payment products in Brazil and Mexico, competing directly in segments where MercadoLibre is growing its credit exposure. Nu Holdings is also accelerating credit card issuance and consumer lending, leveraging a large active user base and increasingly sophisticated underwriting models. As Sea Limited and Nu Holdings expand their fintech footprint and compete more aggressively for the same borrowers, MercadoLibre may face added pressure on credit pricing, acquisition costs and lending margins.
