Argentina's inflation history has impacted the financial behaviour of its population in a way seen in few other countries. Consumers and businesses alike have learned to move money quickly and hold assets in alternative forms where possible; they have also come to distrust institutions that are slow or opaque. 

These conditions have created one of the most active digital wallet and embedded credit markets anywhere in the world. Argentina's experience provides a direct case study in what happens when lending meets mobile financial infrastructure at scale, and issuers that want to break into this market should be paying close attention.

The scale of the digital credit shift

Argentina's payments market is projected to grow from $113.19 billion in 2025 to $569.87 billion by 2031, a CAGR of 30.92%, according to Mordor Intelligence. Banking and digital payment accounts grew approximately 21% between April and August 2024, reaching 228.5 million, according to Chambers and Partners' Fintech 2025 report. Mobile transactions climbed 248% in H1 2024, confirming that the smartphone has become the primary financial interface for a large share of the population.

Within the broader digital adoption narrative in the country, lending merits special attention. Non-bank lending, much of it embedded in digital wallets and fintech apps, reached a stock of AR$ 13.15 trillion (approximately US$9.4 billion) in December 2025, according to consultancy firm EcoGo, and has been growing faster than formal bank credit over recent months. Argentina's BNPL market climbed to $1.62 billion in 2024 and is projected to grow 32.9% in 2025, reaching $2.15 billion. From 2021 to 2024, the sector achieved a CAGR of 53.5%, driven largely by platforms like Mercado Pago and Ualá.

Why digital credit has taken hold

Argentina's economic environment has created conditions where digital credit fills genuine gaps. Inflation reduces the real value of debt over time, which changes how consumers calculate borrowing decisions. Traditional banks have historically been unable or unwilling to extend credit to informal workers, younger consumers and those without established credit histories. Digital platforms, with access to transactional data through their wallets and payment records, can build alternative credit assessments that banks cannot replicate through conventional means.

Mercado Pago expanded its BNPL offering through partnerships with major retailers in early 2024, using AI-based risk assessment to manage credit exposure in a high-inflation environment. Ualá launched an updated BNPL product targeting younger, digitally active consumers at around the same time. These are products built around data, designed for an economy where speed and adaptability are more important than branch networks and paper documentation.

The Buenos Aires Herald reported in early 2026 that non-bank lending has expanded faster than bank credit in recent months, and that debt is filling a gap left by wages that have not kept pace with economic growth. The digital wallets providing that access are reaching segments that banks miss entirely, which is both a commercial opportunity and a social one.

The opportunity for issuing banks and fintechs

For issuing banks and fintechs operating in Argentina, the lesson is clear: the institutions winning in credit are those using transaction data to make faster, more accurate lending decisions, and embedding credit products within the same experience where consumers already manage their money. 

Paymentology's credit card issuing capability allows financial institutions to launch consumer and business credit products at speed, without building their own processing infrastructure. The Decision Engine enables institutions to set and adjust real-time transaction rules, which is particularly relevant in volatile economic environments where risk parameters need to respond quickly to changing conditions. Paymentology's Data Intelligence tools give issuers visibility into spending patterns at the account level, supporting better credit risk decisions and more relevant product offers to individual customers.

Paymentology's hybrid card capability is also worth considering in this context. A card that functions as debit or credit depending on account balance and rules can serve consumers whose financial lives don't fit neatly into fixed credit categories. That describes a significant portion of Argentina's working population, and it is a product type that can serve both established and underserved consumers within a single issuing programme.

Argentina's fintech sector counted 432 companies in 2024, more than doubling since 2019. The institutions that combine smart credit product design with solid issuing infrastructure will be the ones that build durable customer relationships in this market rather than chasing short-term user acquisition.
