Nigerian Banking Sector Faces Escalating Cyber Risks, Auditors Warn

Stakeholders across Nigeria’s banking industry have raised concerns over rising cyber threats and evolving governance risks, calling for urgent adaptation as digital transformation accelerates across the sector.

The warning was issued at the 2026 Annual Retreat, Conference, and General Meeting of the Association of Chief Audit Executives of Banks in Nigeria, held in Lagos. The event brought together audit leaders, regulators, and industry experts under the theme “Navigating Future Technology and Governance Risks in the Nigerian Financial Sector.”

In her opening remarks, ACAEBIN Chairperson, Aina Amah, highlighted the growing centrality of technology in banking operations. She noted that innovations such as artificial intelligence, cloud computing, and fintech integrations are no longer peripheral but foundational to service delivery, risk management, and customer experience.

However, she cautioned that these advancements are introducing increasingly complex risk layers that demand a more proactive and strategic audit approach. She emphasised the need for stronger collaboration among regulators—including the Central Bank of Nigeria and Nigeria Deposit Insurance Corporation—as well as boards and audit professionals to safeguard system resilience and public trust.

Amah identified cybersecurity as the most immediate and pressing threat, warning that failure to address vulnerabilities could expose financial institutions to significant disruption and exploitation by malicious actors.

She also urged auditors to evolve beyond traditional oversight roles, positioning themselves as strategic advisors within their organisations—particularly by engaging early in technology deployment decisions to strengthen risk mitigation frameworks.

On the governance front, Ibukun Beecroft, Partner at Deloitte West Africa, stressed the growing importance of Environmental, Social, and Governance (ESG) considerations. She noted that global sustainability expectations and ethical standards are increasingly shaping financial sector performance and accountability.

“ESG is no longer optional. Sustainable practices and ethical partnerships are essential for long-term stability and profitability,” she said.

The conference featured multiple technical sessions examining key risk areas, including cybersecurity, digital fraud, macroeconomic pressures, and the integration of ESG principles into audit frameworks.

Panel discussions further highlighted the growing complexity of auditing in a digital-first environment. As banks deepen their reliance on digital platforms and third-party service providers, experts stressed the need for enhanced capabilities such as real-time monitoring, predictive risk analytics, and closer collaboration between audit and technology teams.

Overall, participants underscored that safeguarding Nigeria’s financial system will require a more aggressive and coordinated approach to cybersecurity, alongside continuous evolution in governance and audit practices to match the pace of technological change.
