INTRODUCTION
1.1 Background to the Study
The global banking industry has, over the last decade, undergone a far-reaching transformation driven by advances in artificial intelligence (AI). Banks now deploy chatbots, virtual assistants, robotic process automation, and predictive analytics to interact with customers, process transactions, and personalise service offerings. This shift is a response to increasingly demanding customers who expect fast, round-the-clock, and error-free service regardless of channel or time of day. As digital transformation deepens across the financial sector, AI has moved from being an experimental tool to a core component of service delivery strategy in many deposit money banks.
In Nigeria, the adoption of AI in banking has intensified as institutions compete for an increasingly tech-savvy customer base and seek to reduce operational costs while improving turnaround time. Empirical evidence from the Nigerian banking sector suggests that AI-powered applications have improved customer satisfaction by streamlining service processes and lowering operating costs (Olayinka & Adewuyi, 2021). Similarly, studies focused specifically on Nigerian banks have examined how AI-driven technology affects customer satisfaction, reinforcing the growing relevance of the subject within the local industry context.
Beyond satisfaction outcomes, AI technologies such as chatbots and customer analytics are reported to reshape how service is delivered in Nigerian deposit money banks, easing operational bottlenecks and complementing human effort in routine transaction processing. Research within Lagos State banks, for instance, indicates that AI complements existing work processes and that machine-aided tasks ease day-to-day banking operations. Other Nigerian-focused studies have found that AI adoption reduces employee-related costs while simultaneously raising operating expenditure associated with technology infrastructure, reflecting the dual-edged financial implication of AI adoption for banks. Chatbot-specific research has also linked AI usage to improved customer retention, with recommendations that banks become more proactive in creating awareness of AI-enabled services among customers.
United Bank for Africa (UBA) Plc, one of Nigeria’s leading and most internationally diversified financial institutions with operations spanning over twenty African countries alongside the United Kingdom, the United States, and France, has been at the forefront of digital and AI-driven banking innovation in Nigeria. Through initiatives such as its AI-powered virtual assistant “Leo,” UBA has sought to extend banking services beyond the traditional banking hall into conversational and self-service channels accessible via social media and mobile platforms. Given the scale of UBA’s customer base and its pan-African footprint, understanding how AI adoption has influenced the bank’s customer service delivery offers valuable insight not only for UBA’s management but for the broader Nigerian banking industry navigating similar digital transitions.
Despite growing anecdotal and corporate enthusiasm for AI-enabled banking, there remains a need for a focused, evidence-based assessment of how such adoption translates into measurable improvements or otherwise in customer service delivery within a specific Nigerian bank. It is against this backdrop that this study examines the impact of artificial intelligence adoption on customer service delivery using UBA as a case study.
1.2 Statement of the Problem
Nigerian banks have invested substantially in AI-driven platforms with the expectation that these technologies will reduce service delays, cut operational costs, and enhance customer satisfaction. However, customer complaints about failed transactions, unresponsive chatbots, delayed dispute resolution, and impersonal automated interactions remain common across Nigerian banking channels, raising questions about whether AI adoption is delivering the service improvements it promises. Several Nigerian-focused studies have noted that AI adoption in the banking sector still faces implementation barriers, including infrastructural deficits, low digital literacy among some customer segments, and inconsistent AI performance, all of which limit the extent to which its benefits are fully realised.
Furthermore, much of the existing literature on AI and banking service delivery in Nigeria has tended to focus broadly on the banking sector or on multiple banks simultaneously, with limited attention paid to how a specific, large-scale institution such as UBA with its unique pan-African operational structure has been affected by AI adoption in its customer-facing operations. This creates a gap in institution-specific evidence that bank management, regulators, and researchers can draw upon to assess whether AI investments at UBA are translating into tangible service delivery outcomes. It is this gap that the present study seeks to address by specifically examining the impact of AI adoption on customer service delivery at UBA.
1.3 Objectives of the Study
1.3.1 General Objective
The general objective of this study is to examine the impact of artificial intelligence adoption on customer service delivery at United Bank for Africa (UBA).
1.3.2 Specific Objectives
The specific objectives of the study are to:
- examine the effect of AI-driven chatbots on customer service delivery at UBA;
-
assess the influence of AI-powered customer analytics on customer service delivery at UBA;
-
determine the effect of AI-enabled self-service banking channels on customer satisfaction at UBA;
-
identify the challenges affecting the effective adoption of AI for customer service delivery at UBA.
1.4 Research Questions
- What is the effect of AI-driven chatbots on customer service delivery at UBA?
-
What is the influence of AI-powered customer analytics on customer service delivery at UBA?
-
What is the effect of AI-enabled self-service banking channels on customer satisfaction at UBA?
-
What challenges affect the effective adoption of AI for customer service delivery at UBA?
1.5 Research Hypotheses
The following null hypotheses were formulated to guide the study:
• H₀1: AI-driven chatbots have no significant effect on customer service delivery at UBA.
• H₀2: AI-powered customer analytics has no significant influence on customer service delivery at UBA.
• H₀3: AI-enabled self-service banking channels have no significant effect on customer satisfaction at UBA.
1.6 Significance of the Study
This study is significant to several stakeholders. To the management of UBA, the findings will provide empirical evidence on the actual effect of AI investments on customer service outcomes, thereby informing future technology investment decisions. To the broader Nigerian banking industry, the study offers a reference point for benchmarking AI adoption strategies against measurable service delivery indicators. To policymakers and regulators, such as the Central Bank of Nigeria, the findings may support the development of guidelines that encourage responsible and effective AI deployment in the financial sector. To customers, the study draws attention to the strengths and limitations of AI-enabled banking services, which may inform expectations and usage patterns. Finally, to researchers and students, the study contributes to the growing body of literature on AI adoption in emerging-market banking contexts and provides a basis for further research.
1.7 Scope of the Study
The study is focused on examining the impact of artificial intelligence adoption on customer service delivery, using United Bank for Africa (UBA) as a case study. The content scope covers AI-driven chatbots, customer analytics, and self-service banking channels as they relate to customer service delivery. The geographical scope is restricted to selected UBA branches and digital service touchpoints within Nigeria, while the study population comprises UBA staff and customers who interact with the bank’s AI-enabled platforms. The study covers recent developments in AI-driven banking services over the past few years.
