Colombia & Argentina: Emerging Markets for High-Risk Payment Processing

Introduction: Two Markets, Two Completely Different Challenges – One Major Opportunity

When fintech strategists and payment infrastructure providers map out LATAM expansion priorities, Brazil and Mexico dominate the conversation. And for good reason, they are the region’s largest economies by a significant margin. But in 2026, the most strategically interesting emerging markets for high-risk payment processing in Latin America are Colombia and Argentina.

These two countries could not be more different in their economic character. Colombia is a stable, growth-oriented market with a sophisticated fintech regulatory framework, a rapidly digitalising urban population, and a Superintendencia Financiera that has shown real willingness to engage constructively with payment innovation. Argentina, by contrast, is a market defined by macroeconomic turbulence, persistent inflation, strict currency controls, and a population that has turned to stablecoins and digital assets as a genuine hedge against peso devaluation.

Yet both markets share a defining characteristic that makes them urgent priorities for operators running high-risk merchant accounts: massive, underserved demand for digital financial services, in iGaming, forex trading, cryptocurrency, digital content, and cross-border e-commerce, paired with a payment infrastructure that is evolving fast enough to serve it.

This guide covers everything high-risk merchants, fintech operators, and payment service providers need to know about building a compliant, efficient payment operation in Colombia and Argentina in 2026.

Part One: Colombia – Stable Growth, Sophisticated Regulation, Real Opportunity

Why Colombia Is on Every High-Risk Merchant’s Radar

Colombia is the third-largest economy in Latin America, with a population of 52 million, a rapidly growing digital middle class, and a fintech ecosystem centred in Bogotá, Medellín, Cali, and Barranquilla that ranks among the most innovative in the region.

Digital commerce in Colombia has grown at a compound annual rate exceeding 20% over the past three years. Smartphone penetration is above 75%. And critically for high-risk operators, Colombian consumers are active participants in online gaming, sports betting, forex trading, and subscription digital services, often serviced by offshore platforms operating in a regulatory grey zone that is now beginning to formalise.

The Colombian government’s approach to digital commerce and fintech regulation has been notably progressive. The Superintendencia Financiera de Colombia (SFC) has implemented a regulatory sandbox framework that allows innovative payment and financial services businesses to test and scale within a supervised environment, a model that reduces the entry risk for well-structured operators.

The Colombian Payment Ecosystem: What High-Risk Merchants Must Support

PSE (Pagos Seguros en Línea) is the cornerstone of Colombian online payment infrastructure. Operated by ACH Colombia, PSE enables direct bank debit transfers from over 30 participating Colombian financial institutions, including Bancolombia, Davivienda, BBVA Colombia, and Banco de Bogotá. For any high-risk merchant building a payment gateway for Colombia, PSE integration is non-negotiable. It is used by millions of Colombian consumers for everything from utility bills to e-commerce purchases to online gaming deposits.

Efecty is Colombia’s largest cash payment network, with over 9,000 physical agent locations, in shopping centres, pharmacies, and neighbourhood stores, across every Colombian department. Like OXXO Pay in Mexico, Efecty serves as a cash-to-digital bridge for Colombia’s underbanked population. For high-risk merchants in iGaming, digital content, and subscription services targeting Colombian consumers in Tier 2 cities like Bucaramanga, Pereira, Cúcuta, and Ibagué, Efecty access meaningfully expands the addressable market.

Nequi and Daviplata are mobile wallets operated by Bancolombia and Davivienda respectively, each with millions of registered Colombian users. These platforms enable peer-to-peer transfers and merchant payments without requiring a traditional bank account, making them important channels for reaching younger, digitally-native consumers in Bogotá and Medellín. Nequi alone had over 17 million registered users as of 2025, making it one of the most significant digital financial platforms in the country.

Credit and Debit Cards remain relevant in Colombia, particularly among higher-income urban consumers. Visa and Mastercard debit cards are prevalent across banked Colombian consumers, though high-risk MCC classifications will affect issuer approval rates, a dynamic that makes PSE and Efecty alternatives strategically important for maintaining conversion rates.

Securing a High-Risk Merchant Account in Colombia

Obtaining a high-risk merchant account for Colombian operations requires navigating both the local regulatory landscape and the banking sector’s conservative approach to high-risk verticals.

The SFC oversees financial services providers, and while it does not directly licence merchant acquirers, it regulates the Colombian banks and PSPs that provide acquiring services. Offshore-licensed businesses, common in iGaming and forex, must demonstrate clear compliance with Colombian consumer protection laws, data privacy regulations (Ley 1581 de 2012), and AML obligations under SARLAFT (Sistema de Administración del Riesgo de Lavado de Activos y de la Financiación del Terrorismo).

When approaching a high-risk merchant account provider for Colombia, be prepared to provide:

  • Corporate documentation and UBO disclosures
  • Offshore regulatory licence (for iGaming, forex, or fintech verticals)
  • Colombian legal entity registration or established legal representative
  • AML and KYC policy documentation aligned with SARLAFT principles
  • Website, terms and conditions, and consumer-facing compliance materials in Spanish
  • Processing history with chargeback ratio data
  • Projected monthly COP and USD settlement volumes

PSP and acquiring relationships in Colombia are concentrated among a smaller number of players than in Brazil or Mexico, making the relationship with a specialist high-risk merchant account provider who already has established Colombian banking partnerships significantly more valuable.

Colombia Regulatory Update: 2026

Online gambling regulation is advancing. Colombia became the first country in Latin America to regulate online gambling when Coljuegos issued its first online gaming licences in 2016. The regulated market has matured significantly, and 2026 sees a more enforcement-focused Coljuegos posture against unlicensed offshore operators. Licensed operators benefit from cleaner banking access, but must comply with Coljuegos’ payment provider registration requirements.

Open Banking framework is under development. The SFC has been advancing an Open Finance framework for Colombia modelled in part on Brazil’s experience. When implemented, it will create new payment initiation infrastructure that could significantly benefit high-risk merchants by enabling direct bank debit flows beyond PSE’s existing model.

Crypto regulation is formalising. Colombia’s financial regulators have moved toward a clearer framework for digital asset services, following a period of informal prohibition. Crypto-related businesses seeking to operate with Colombian banking access should monitor SFC guidance closely through 2026.

Part Two: Argentina – High Complexity, High Reward

Understanding Argentina’s Unique Economic Reality

Argentina is unlike any other market in Latin America, or arguably anywhere in the world, for payment infrastructure operators. The country’s history of currency crises, recurring inflation, and strict capital controls has created a payment and financial environment of extraordinary complexity that simultaneously creates enormous opportunity for operators who understand it.

In 2026, Argentina’s economy continues to navigate a post-crisis stabilisation programme, with annual inflation rates that, while declining from their 2023–2024 peaks, remain among the highest in the world. The Argentine peso (ARS) continues to trade at a significant discount against informal USD exchange rates, and the BCRA (Banco Central de la República Argentina) maintains controls on foreign currency access that shape every aspect of merchant payment processing in the country.

For high-risk merchants, particularly those in iGaming, forex trading, crypto, and digital content, Argentina represents one of the most active consumer markets in LATAM for their products. Argentine consumers are sophisticated, digitally engaged, and highly motivated to access digital financial products that offer value or protection against inflation. The challenge is building payment infrastructure that actually works within Argentina’s regulatory constraints.

The Argentine Payment Ecosystem: Navigating Complexity

Mercado Pago is the dominant digital payment platform in Argentina, operated by MercadoLibre Latin America’s largest e-commerce and fintech company. Mercado Pago functions as a digital wallet, payment gateway, and financial account for millions of Argentine consumers, and its deep penetration across Buenos Aires, Córdoba, Rosario, Mendoza, and secondary cities makes it an essential integration for any merchant targeting the Argentine market. Critically, Mercado Pago supports ARS transactions and manages FX complexity internally, making it one of the most operationally accessible channels for foreign merchants.

Rapipago and Pago Fácil are Argentina’s primary cash payment networks, the equivalent of OXXO Pay in Mexico and Efecty in Colombia. With thousands of physical agent locations across Argentina, these networks serve the significant portion of Argentine consumers who prefer cash transactions or lack formal banking relationships. For iGaming operators, digital content platforms, and subscription services targeting a broad Argentine consumer base, Rapipago and Pago Fácil integration is essential for reaching beyond the banked population.

Transferencias bancarias (bank transfers) via CBU (Clave Bancaria Uniforme) remain a core payment method for Argentine consumers transacting online. The CBU system enables transfers between Argentine bank accounts, and many online merchants accept CBU transfers directly, though reconciliation and fraud management for manual bank transfer payments require robust operational processes.

Stablecoins – particularly USDT: have achieved remarkable penetration in Argentina as a practical hedge against peso devaluation. Argentine consumers use USDT for savings, cross-border payments, and increasingly for high-risk merchant transactions where USD-denominated pricing is preferred by both the consumer and the merchant. For forex, crypto, and iGaming operators in particular, offering USDT deposit and withdrawal options in Argentina can significantly improve conversion among more sophisticated user segments.

The Argentine FX Challenge: Managing Currency Controls

The defining operational challenge for high-risk merchants in Argentina is currency, specifically, how to price products in a way that Argentine consumers can afford, how to collect payments in a legally compliant manner, and how to repatriate revenue in a currency that retains value.

Several operational models are used by international merchants in Argentina:

USD-denominated pricing with ARS conversion at checkout: the merchant prices in USD, and the checkout converts to ARS at the official or semi-official exchange rate. This is the most straightforward approach but may result in consumer resistance if the ARS price feels expensive relative to informal USD rates.

Local ARS acquiring with offshore USD settlement: a specialist high-risk merchant account provider collects in ARS locally and converts to USD for merchant settlement. The FX spread and conversion mechanism used here are critical commercial variables, providers vary significantly in the rates and terms they offer.

Stablecoin settlement: for merchants comfortable operating in the crypto rails, accepting USDT deposits and settling in USDT bypasses ARS/USD conversion challenges entirely. This model requires a provider with regulated or compliant crypto payment processing capabilities.

Securing a High-Risk Merchant Account in Argentina

Argentina’s banking sector has historically been among the most restrictive in LATAM for high-risk merchant onboarding. The BCRA’s oversight of foreign currency flows means that merchants settling in USD face additional scrutiny, and banking relationships are often mediated through fintech intermediaries rather than direct bank accounts.

Specialist high-risk merchant account providers operating in Argentina typically structure merchant accounts through either licensed Argentine payment service providers or through cross-border acquiring arrangements that allow ARS collection with offshore settlement. When evaluating providers for Argentina:

  • Confirm their regulatory standing under BCRA and CNV (Comisión Nacional de Valores) frameworks
  • Understand their FX settlement mechanism and the spread applied to ARS/USD conversion
  • Assess their chargeback management capability — Argentine chargeback rates in high-risk verticals are elevated
  • Evaluate their stablecoin payment support if your consumer base skews toward USDT usage
  • Confirm their experience with Argentine-specific consumer protection regulations under Ley de Defensa del Consumidor

Argentina Regulatory Update: 2026

BCRA capital controls are gradually easing. Argentina’s government has been progressively relaxing some foreign currency restrictions as part of its IMF-aligned economic stabilisation programme. While significant controls remain, 2026 represents a more navigable environment than 2023–2024 for merchants seeking to repatriate USD revenues from Argentine operations.

Crypto regulation is actively developing. Argentina’s CNV and BCRA have issued guidance on virtual asset service providers (VASPs), and the regulatory framework for crypto businesses is becoming clearer. For iGaming, forex, and fintech operators who accept crypto payments from Argentine consumers, compliance with VASP registration requirements is increasingly relevant.

Online gambling remains largely unregulated at the national level. Unlike Colombia, Argentina does not have a national online gambling licensing framework, gambling regulation in Argentina is managed province by province. Buenos Aires province and the City of Buenos Aires have the most developed provincial licensing structures, while other provinces remain effectively unregulated. This creates both opportunity and complexity for iGaming operators entering the market.

Building Payment Infrastructure Across Both Markets: Key Principles

For high-risk merchants targeting both Colombia and Argentina, or building a broader LATAM payment stack, several operational principles apply across both markets:

Never rely on card processing alone. PSE, Efecty, Nequi, Mercado Pago, Rapipago, and Pago Fácil collectively serve far more consumers in these markets than card rails can reach. A payment gateway without deep LPM integration will consistently underperform.

Choose a provider with genuine local expertise, not just regional coverage. There is a significant difference between a high-risk merchant account provider who claims LATAM coverage and one who has actual banking relationships, PSP partnerships, and compliance infrastructure specifically in Colombia and Argentina. The difference shows up immediately in approval rates, settlement reliability, and chargeback ratios.

Build compliance in from the start. SARLAFT in Colombia and BCRA regulations in Argentina are not optional frameworks to address post-launch. Merchants who enter these markets without proper AML, KYC, and consumer protection compliance face banking relationship termination and potential regulatory action.

Plan for FX complexity in Argentina from day one. USD revenue repatriation from Argentina requires a structured approach, providers, legal entities, and pricing models should all be designed with currency management as a core consideration, not an afterthought.

Conclusion: Colombia and Argentina Reward the Prepared Operator

Colombia and Argentina represent genuinely exciting frontiers for high-risk payment processing in Latin America in 2026. Colombia offers regulatory stability, a growing digital consumer base, and a clear path to compliant operations for well-prepared merchants. Argentina offers access to one of the most commercially sophisticated and digitally engaged consumer populations in the region, if you can navigate its uniquely complex macroeconomic and currency environment.

In both markets, the foundation is the same: the right payment gateway with deep local payment method support, a specialist high-risk merchant account structure built on genuine local banking relationships, and a high-risk merchant account provider with real country-specific expertise.

The operators who invest in that foundation now are the ones who will capture Colombia and Argentina’s digital commerce growth as both markets continue to mature in the years ahead.
