As Latin America prepares for 2026, the resilience of its financial sector is increasingly dependent on the management of risks associated with generative AI (GenAI), regulatory inconsistencies across regions, and the expanding interconnectedness of fintech ecosystems. Experts warn that systemic vulnerabilities are not limited to isolated threats; instead, they arise from complex, cross-cutting risks that financial institutions must address.
According to Eric Mejía, CTO of Banco Sabadell, the competitive edge in this evolving landscape will not stem from simply avoiding attacks but rather from an organization’s ability to respond effectively. “The true competitive advantage will not be in avoiding all attacks, but in responding better than anyone else. Financial institutions must combine vision, data, and talent capable of anticipating the unexpected,” he noted. This perspective signals a transition from mere defense strategies to proactive operational resilience, focusing on adaptability amid unforeseen challenges.
The risk landscape for 2026 is notably shaped by advanced technologies that have transformed traditional security frameworks. The rapid advancement of GenAI has democratized sophisticated tools previously reserved for experts, facilitating highly targeted phishing campaigns and the creation of convincing deepfakes aimed at circumventing biometric authentication and social engineering defenses. As financial institutions become increasingly reliant on digital interactions, these threats are likely to escalate.
Compounding these technological challenges is the fragmented regulatory environment within Latin America. The disparity in cybersecurity maturity levels across countries creates arbitrage opportunities for cybercriminals, who exploit regulatory gaps to penetrate interconnected financial ecosystems. In an Open Finance context, the vulnerability of a single institution could jeopardize the integrity of the entire transactional network, particularly within instant payment systems where the speed of account-to-account transfers offers limited time for fraud detection.
In response to these emerging threats, financial institutions are revamping their defense architectures. This includes the adoption of quantitative risk methodologies and collaboration with managed security service providers that offer continuous monitoring. A significant portion of funding is being directed toward post-quantum cryptography (PQC) solutions. Although commercial-scale quantum computing is still on the horizon, preparing current data against potential future decryption threats is becoming a crucial compliance and security priority.
Moreover, the evolution of fraud prevention systems has shifted from static, rule-based models to dynamic machine learning frameworks that analyze user behavior in real time. This allows for the suspension of suspicious transactions without inconveniencing legitimate customers. Additionally, multifactor authentication and advanced biometric measures are emerging as fundamental regulatory requirements alongside greater transparency and incident reporting obligations.
Looking ahead, supervisory bodies in Latin America are expected to adopt a more facilitative role in fostering innovation while mitigating risks. Regulatory sandboxes are likely to become more commonplace, allowing financial institutions to experiment with technologies like blockchain and AI in controlled settings. This approach seeks to balance the need for security with the flexibility essential for promoting financial innovation.
As Latin America’s financial sector navigates this complex landscape, the ability to adapt to rapidly evolving threats and regulatory frameworks will be crucial. The ongoing integration of advanced technologies and the establishment of more cohesive regulatory environments will likely define the region’s financial stability and growth in the coming years.
