In a recent episode of AI Impact Talk, host Thembekile Mrototo engaged in an insightful conversation with Dr Mark Nasila, Chief Data and Analytics Officer of FNB Risk. The discussion explored how artificial intelligence is transforming the banking sector, particularly focusing on the emergence of generative AI and agentic AI technologies.
Nasila provided clarity on the evolution of AI technologies, explaining that while traditional AI enabled machines to execute forms of human intelligence, generative AI has advanced to creating content that resembles human output. The conversation highlighted the next frontier: agentic AI, which possesses autonomous characteristics allowing systems to perceive environments, learn from data, make decisions, and act on them—essentially mimicking human reasoning capabilities.
For large financial institutions like FNB, these technologies are transforming business operations in several ways. AI systems are automating numerous functions, enhancing digital customer experiences, and allowing the bank to be more proactive in meeting challenges in risk management. Nasila emphasized that AI tools are particularly valuable in navigating today’s complex reality marked by geopolitical complications, fluctuating interest rates, and emerging risks.
A significant portion of the discussion centred on how AI is reshaping risk management at FNB. Their systems now identify and rank incidents such as potential fraud or money laundering, allowing human staff to focus on making decisions rather than gathering insights. As Nasila noted, this technology processes over 200,000 investigations and generates reports for decision-making, freeing up employees to concentrate on higher-level analysis.
The conversation also touched on the geopolitical dimensions of AI development, particularly the concept of “sovereign AI”—a nation’s ability to control the AI development value chain. Nasila explained how countries are investing heavily in AI technologies, recognizing their impact on national security, social problem-solving, and future industrialization. He highlighted recent developments from Asia, particularly mentioning “Deepseek”; which has redefined the global AI race by demonstrating that powerful AI can be developed at a fraction of Western costs.
When discussing Africa’s position in the global AI landscape, Nasila pointed out that while there have been numerous startups and proof-of-concept initiatives across the continent, African nations generally lack clearly defined AI strategies compared to countries like China or regions like the European Union. He identified several challenges hindering Africa’s progress: the tendency to position itself as a consumer rather than creator of technologies, issues with infrastructure readiness, data access, and the need for upskilling society.
For the banking sector specifically, Nasila described how AI is helping FNB meet the dual challenges of increasing competition and rising customer expectations. The technology is enabling them to redefine banking context, moving beyond merely iterating products to proactively addressing customer needs. This includes developing chatbots for on-demand service, using algorithms to better understand customers, and employing AI to swiftly identify security incidents.
Throughout the conversation, Nasila emphasized that while AI offers tremendous opportunities for efficiency and personalization, the human element remains crucial—particularly for empathy in customer interactions. The technology, he suggested, isn’t replacing human intelligence but rather augmenting it, allowing staff to focus on uniquely human contributions while AI handles more routine tasks.
As AI continues to transform the financial sector, FNB’s approach illustrates how banks are leveraging these technologies not only to improve operations but also to create safer, more responsive banking environments that Nasila likened to a “neighbourhood that is safe, that looks after your interests.”
