This regulatory backing, combined with growing consumer demand for accessible digital financial services, underscores the strategic importance of BaaS in promoting financial inclusion across the region. By bridging gaps in traditional banking infrastructure, these platforms are empowering individuals, SMEs, and enterprises to access seamless, flexible, and integrated financial solutions, positioning South America as a rapidly evolving hub for fintech-led innovation.

Banking as a ServiceSegmentation

The platforms component is the largest in South America because it enables banks, fintechs, and businesses to deliver integrated and scalable financial services across diverse markets with minimal infrastructure investment.

The platforms component dominates the South American Banking as a Service market due to its ability to provide end-to-end financial solutions that can be customized and deployed quickly across the region’s highly diverse economic and regulatory environments. Platforms combine core banking functionality, API access, payment processing, compliance management, and analytics into a single modular system, allowing businesses to offer banking services without creating infrastructure from scratch. In countries such as Brazil, Argentina, and Chile, where financial inclusion remains a critical issue, these platforms allow fintechs and neobanks to reach underserved populations by embedding digital wallets, lending, and payment solutions directly into mobile apps and e-commerce platforms. Regulatory initiatives like Brazil’s open banking framework and instant payments system, Pix, have accelerated platform adoption by standardizing APIs, enabling interoperability, and encouraging collaboration between traditional banks and technology companies. Large banks leverage platforms to modernize legacy systems, streamline cross-border operations, and expand offerings without the risk of infrastructure disruption. Startups and smaller businesses use these platforms to quickly test and deploy financial products, access compliance modules, and integrate payment services for domestic and international transactions. The flexibility of platforms also allows for multi-tenant configurations, supporting multiple clients or business lines simultaneously while maintaining security and regulatory compliance. Furthermore, platforms provide advanced features such as real-time analytics, fraud monitoring, and customer behavior insights, which are increasingly important for businesses aiming to personalize financial services.

On-premises deployment is the fastest growing segment in South America because it allows organizations to maintain regulatory compliance, data control, and operational security in complex and evolving markets.

The rapid adoption of on-premises deployment in South America is closely linked to the need for financial institutions, fintechs, and enterprises to exercise full control over their infrastructure while complying with local regulations and protecting sensitive customer data. Many countries in the region have stringent data localization requirements and sector-specific regulations that require companies to store and manage financial information within national borders, making on-premises solutions preferable. These deployments allow institutions to directly monitor transaction flows, manage databases, and implement security protocols tailored to specific operational and regulatory requirements. On-premises systems are particularly valuable for large-scale operations, cross-border payments, and real-time transaction processing, where latency, control, and reliability are critical. Financial institutions that operate in regions with varying levels of internet infrastructure or cybersecurity maturity also find on-premises setups advantageous because they can maintain consistent service quality without relying on third-party cloud providers. The ability to integrate on-premises solutions with legacy banking systems is another key factor, as many South American banks and enterprises still rely on traditional core banking platforms that are not easily migrated to the cloud. On-premises deployment further allows organizations to customize disaster recovery, data encryption, and access controls to meet internal risk management standards. With the rise of digital banking, fintech solutions, and mobile-first financial services, institutions are increasingly choosing on-premises deployment to maintain control over operational performance, security, and regulatory compliance while supporting innovation. This data control, regulatory adherence, security, and compatibility with legacy systems explains why on-premises deployment is the fastest growing segment in South America’s Banking as a Service market.

Large enterprises are the largest segment in South America’s BaaS market because they require complex, scalable, and compliant financial solutions to manage extensive operations and customer bases across multiple countries.

Large enterprises dominate the South American Banking as a Service market due to the scale and complexity of their financial operations, which often include cross-border transactions, large transaction volumes, payroll management, and embedded financial services for customers and partners. These organizations rely on BaaS platforms to deliver secure, efficient, and compliant banking functionalities without maintaining full in-house infrastructure. Large banks, multinational corporations, and technology firms leverage BaaS to integrate payment processing, account management, lending, and compliance tools into their systems, enabling rapid innovation while adhering to local and regional regulatory frameworks, such as Brazil’s open banking initiative and data protection laws. The scalability of BaaS platforms allows these enterprises to expand offerings across multiple markets and support diverse business lines simultaneously. Large enterprises also benefit from advanced security, monitoring, and fraud prevention features, which are essential when handling high-value transactions and sensitive financial data. By using BaaS, these organizations can offer seamless digital experiences to consumers and business partners, automate financial workflows, and reduce operational complexity associated with legacy banking systems. The operational scale, regulatory demands, technological requirements, and the need for innovation-driven solutions has positioned large enterprises as the largest organization size segment in South America’s Banking as a Service market, enabling them to serve extensive customer bases, modernize infrastructure, and deliver complex financial services efficiently across the region.

Brazil leads the South American Banking as a Service Market because of its rapid digital banking adoption, progressive financial regulations, and a vibrant fintech community addressing underserved populations

Brazil has emerged as the leading country in South America’s Banking as a Service landscape largely because of the way it has combined regulatory innovation with strong consumer demand for digital solutions and a fintech ecosystem that thrives on solving real-world financial access challenges. The Brazilian central bank has played a pivotal role by introducing groundbreaking initiatives such as the instant payments system Pix and open banking regulations, both of which have dramatically reshaped how consumers and businesses interact with financial services. These frameworks have not only made digital transactions faster and more accessible but also encouraged collaboration between traditional banks and fintech companies that deliver services via modern API-driven models, directly fueling the expansion of BaaS. The population in Brazil has been highly receptive to digital banking, with millions of consumers embracing mobile-first neobanks like Nubank, which have demonstrated the power of embedding financial services into user-friendly platforms. This widespread adoption reflects both a young, tech-oriented demographic and the reality that many Brazilians were historically underbanked or underserved by traditional financial institutions, creating fertile ground for fintech-led innovation. Venture capital investment in the country has also surged, with global investors viewing Brazil as the gateway to Latin American fintech growth, which in turn has allowed BaaS providers to scale quickly. Traditional banks in Brazil, facing competitive pressure from agile fintechs, have increasingly sought to modernize their offerings by partnering with technology providers rather than relying solely on legacy systems, further strengthening the collaborative environment necessary for BaaS to thrive.
