How is the global banking technology transformation reshaping Brazil's digital financial competitiveness?

Structural Opportunities for Brazilian Fintech from Five Major Bank Tech News

In June 2026, a series of significant events occurred intensively in the global banking technology sector: Nigeria's Interswitch chose Temenos to expand into the African market, Greece's National Bank of Greece (NBG) completed the largest core banking transformation in its history, UAE's Mawarid Finance migrated its core from Oracle Flexcube to BML Istisharat, New Jersey's First Commerce Bank migrated to FIS Horizon to accelerate AI adoption, and Finastra sold its US middle-market banking business to Cora Group. On the surface, these events have little to do with Brazil, but upon deeper analysis, they collectively point to a trend: The global financial industry is accelerating its embrace of open, cloud-native, AI-driven core systems — which has structural implications for Brazil, the largest and most active fintech market in Latin America.

Key Observation 1: Core System Modernization Becomes a "Must-Answer Question" for Global Banking

From NBG's years-long migration of 120,000 customers and 12 million deposit accounts, to First Commerce replacing its core platform to embrace AI, to Mawarid abandoning Oracle Flexcube for a localized Islamic banking system, these cases all show: Regardless of bank size or geography, legacy core systems are becoming a bottleneck for digital transformation. The situation in Brazil is particularly unique: the country has some of the largest traditional banks in the world (such as Itaú, Bradesco, Santander Brasil), with systems mostly built in the 1980s and 1990s, facing increasingly urgent demands for real-time payments, open banking, and AI support. The success of PIX has already proven Brazil's capability in payment innovation, but can the core systems beneath the payment layer support the next wave of innovation? Referring to NBG's Cosmos project, a core migration of that scale requires strong technical execution and long-term investment. Are Brazil's banks prepared for a similar five-year plan?

Key Observation 2: The Combination of Cloud Migration and AI Is Creating New CompetitivenessOne of the core reasons First Commerce chose FIS Horizon is the "standardised data feeds and agentic commerce tools" — that is, standardized data flows and autonomous commerce tools. This reveals that the implementation of AI in banking increasingly relies on the standardization of underlying data. Brazilian fintech companies like Nubank and C6 Bank were born cloud-native, and their data architectures naturally support AI; traditional banks, however, face data silo issues. Furthermore, after selling its U.S. business, Finastra retained the Essence core platform, indicating that large technology vendors are refocusing — platforms like Temenos, FIS, and Infosys Finacle will pay more attention to software delivery capabilities. For small and medium-sized banks and credit unions in Brazil, this may mean more mature and cost-effective cloud core solutions are available, thereby narrowing the technology gap with major banks.### Which industries benefit?

The industries that benefit most directly are Brazilian fintech and IT services. First are consulting, implementation, and cloud service companies related to core system migration, such as Accenture, IBM (already playing a role in the NBG project), and enterprises with delivery centers in Brazil. Second are cloud infrastructure providers like Oracle Cloud Infrastructure (OCI used in the Mawarid case), AWS, and Azure; as more banks move to the cloud, cloud spending will increase. Additionally, AI-driven anti-fraud, credit decision, and customer interaction solutions will also benefit. Brazilian fintech companies that can provide AI solutions based on standardized data will have a huge market.

Which industries are under pressure?

The ones under pressure are traditional IT system integrators and outdated localized software vendors. As core systems migrate to cloud-native, microservices architectures, companies that rely on customized development and maintenance of legacy systems will gradually lose business. In addition, the internal IT departments of large banks also face challenges — if they cannot quickly keep up with modernization, they will see their market share eroded by more efficient digital banks and fintech companies. Furthermore, traditional bank software licensing models will also be impacted by the SaaS subscription model.

What does it mean for the Brazilian economy?

For the Brazilian economy, the deepening of digital finance will improve capital allocation efficiency. More efficient core systems mean lower operational costs, faster credit approval, and better risk management — these will ultimately be transmitted to the real economy. Especially in the MSME and consumer credit sectors, more advanced banking technology can lower the service threshold. At the same time, as one of the fastest-growing segments of Brazil's digital economy, fintech's technological progress will enhance Brazil's leadership in fintech in Latin America and even globally, attracting more foreign capital and talent.

What does it mean for the export market?

Export of fintech software and services is a potential area for Brazil. Currently, Brazilian fintech companies mainly serve the domestic market, but companies like Nubank have successfully entered Mexico and Colombia. If Brazilian domestic bank core system vendors (such as some startups) can build competitive products, they can follow the path of Temenos and Infosys and export to other emerging markets. In addition, Brazil's PIX technical architecture has been adopted by several countries, representing a possibility for software exports.

What does it mean for investors?Investors should closely monitor Brazilian banks' core system upgrade plans and fintech infrastructure companies. Companies with differentiated technologies, such as startups focused on core banking migration, payment engines, or AI-powered risk control, may become acquisition targets. Meanwhile, announcements of partnerships between global technology vendors (such as FIS, Temenos, Finastra) and Brazilian banks will send positive signals. Another investment opportunity lies in local tech companies providing cloud migration services for banks and Banking-as-a-Service (BaaS) platforms.

What does it mean for the next 5 years?

Over the next five years, Brazil's bank IT spending is expected to continue growing, with core system modernization becoming mainstream. This could lead to: 1. Deeper collaboration between traditional Brazilian banks and large tech companies, with some banks adopting outsourcing or SaaS models to replace in-house systems. 2. Increased fintech M&A, where startups with core technologies or customer relationships are acquired by banks or global vendors. 3. Brazilian financial regulators (such as BCB) may introduce new open banking and cloud migration guidelines, affecting the pace of implementation. 4. If Brazil can seize this round of technological iteration opportunities, its digital financial infrastructure will become more efficient, thereby supporting higher credit penetration and economic growth.

Conclusion

The five banking technology news items from June 2026 may seem remote, but they are a microcosm of the global financial infrastructure upgrade. As the largest economy in Latin America, Brazil's financial system modernization faces both significant execution challenges and investment opportunities that cannot be ignored. Whether drawing on Greece's NBG system engineering experience or learning from Africa's Interswitch SaaS transformation, Brazilian banks and technology companies need to accelerate their actions to remain competitive in the next five years.
