Pulse Analysis

The informal economy is a structural pillar of Latin America, with micro, small and medium enterprises comprising virtually the entire merchant landscape. These businesses often operate outside formal credit channels, lack digital invoicing, and remain cash‑centric, creating a blind spot for regulators and banks. Yet this fragmentation presents a fertile ground for fintechs that can supply the missing infrastructure—digital wallets, real‑time settlements, and data‑driven credit scoring—turning a perceived weakness into a growth engine.

Real‑time payment rails, epitomized by Brazil’s Pix, are reshaping how merchants transact. Since launch, Pix has handled roughly 196 billion transactions and moved about $16 trillion, reaching 90% of the population. By integrating Pix into merchant‑facing solutions such as PayPal’s SMB suite and Mercado Pago’s checkout, fintechs are eliminating the cash‑to‑digital bottleneck. These integrations embed payment acceptance directly into inventory, invoicing, and working‑capital workflows, reducing friction for both consumers and sellers and unlocking new data streams for credit underwriting.

The competitive arena is heating up as regional giants double down on fintech. MercadoLibre’s 45% revenue surge was driven by its Mercado Pago platform, which offers merchants end‑to‑end financial services. Nubank’s 15% customer growth to 131 million users underscores the appetite for accessible banking. As these players expand into lending, cash‑flow analytics, and supplier payments, the informal sector will gradually migrate into the formal financial system, boosting tax bases, improving credit access, and cementing fintech’s role as a catalyst for inclusive economic development.
