Background of the Study
Open banking represents a paradigm shift in the financial services industry, enabling secure data sharing between banks and third-party providers to foster innovation and enhance customer choice. At Wema Bank in Abuja, open banking initiatives are being introduced to break down traditional silos and offer customers a more integrated and flexible banking experience. By allowing authorized access to customer data through application programming interfaces (APIs), open banking creates opportunities for personalized financial services, innovative payment solutions, and enhanced product offerings (Okoro, 2023). This model not only drives competition but also encourages collaboration between banks and fintech companies, potentially transforming the retail banking landscape. However, the implementation of open banking is fraught with challenges, including data privacy concerns, regulatory uncertainties, and the need for robust cybersecurity measures. The complexities of integrating legacy systems with new API-driven architectures further complicate the transition, potentially disrupting service delivery. This study evaluates the challenges encountered by Wema Bank in implementing open banking, assessing both the technical and operational hurdles that must be overcome to realize its full potential, and exploring strategies to address these issues while ensuring customer trust and regulatory compliance (Chinwe, 2024; Akinola, 2025).
Statement of the Problem
Wema Bank faces significant obstacles in its open banking initiatives. Key challenges include the integration of disparate legacy systems with modern API frameworks, which can result in technical incompatibilities and service disruptions. Additionally, concerns about data security and privacy persist, as customers and regulators scrutinize the risks associated with sharing sensitive financial information with third-party providers. Regulatory uncertainty further complicates the environment, as evolving guidelines require continuous adaptation by the bank. Moreover, insufficient customer awareness and digital literacy impede widespread adoption of open banking services, limiting the potential benefits of enhanced service personalization and innovation. These challenges create a disconnect between the theoretical benefits of open banking and its practical implementation, ultimately hindering the bank’s ability to fully leverage data-driven innovations for improved customer service and competitive advantage.
