Abstract
This research looks at how the use of artificial intelligence (AI) technologies is changing the way people invest in Nepal's commercial banking industry. There is not much real-world evidence of how banks in developing countries like Nepal use and profit from AI-driven investment strategies, even though this is a growing trend throughout the world. This study uses a mixed-methods approach, which means it uses both structured questionnaires given to investment teams and semi-structured interviews with senior investment managers and technology officers from five major commercial banks: Nabil Bank Limited, Nepal Investment Mega Bank Limited, Global IME Bank Limited, NIC Asia Bank Limited, and Himalayan Bank Limited. The research is based on secondary data from yearly reports and regulatory papers. The results show that AI technologies are being used more and more in portfolio optimization, risk assessment, and market forecasting, which makes decisions more data-driven and efficient. However, widespread use is hindered by problems including unclear regulations, a lack of technological know-how, and the need to work with older systems. This study adds to the body of research by showing how AI is changing investment strategies in Nepalese banks and giving policymakers and industry executives who want to move the financial sector forward in terms of digital transformation useful information.

Introduction
Background: AI in Banking and Investment Globally
Artificial intelligence (AI) has completely changed the way people bank and invest throughout the world. Banks currently use machine learning, natural language processing, and big data analytics to automate complicated operations including optimizing portfolios, assessing credit risk, and predicting the market (Baker et al., 2019; Chen, Zhang, & Zhang, 2021). AI-powered systems let people make decisions more quickly and accurately, save operating expenses, and give tailored financial advice through robo-advisory platforms (Gomber et al., 2018). McKinsey & Company (2020) says that AI applications might bring up to $1 trillion in value to the global banking industry per year. AI technologies are already vital to current investing strategies in developed markets. They help institutions evaluate huge amounts of structured and unstructured data to find patterns, assess risk, and react to market changes in almost real time (Bussmann, 2017). This change is part of a larger trend away from making decisions based on gut feelings and toward financial methods that are based on facts and algorithms.
Why AI Adoption Matters in Nepalese Context
Over the past twenty years, Nepal's commercial banking industry has developed a lot. This is shown by an increase in assets, customers, and services (Nepal Rastra Bank, 2023). In the past, Nepalese banks made investment decisions based on manual analysis, limited historical data, and cautious asset allocation strategies (Shrestha & Joshi, 2018). But banks have tremendous reasons to upgrade their investment strategies using AI because of more competition, rising client expectations, and the growth of digital banking. The Nepal Rastra Bank (NRB) has pushed for digital innovation to improve efficiency and make sure everyone has access to financial services (NRB, 2022). AI implementation might help banks in Nepal better handle credit and market risk, make more money, and follow global best practices (Karki, 2020). Because South Asia is moving so quickly in terms of technology, it's important to understand how Nepalese banks are using AI to stay competitive and strong in a shifting financial environment. Research Gaps: There is a lot of worldwide research on AI in banking (for example, Frost et al., 2019; Huang et al., 2020), but there are not many empirical studies that look at how it is used in investment strategies in Nepal's banking system. Most of the local research that has been done so far has looked at how AI can be applied in customer care, payments, or digital banking channels (Adhikari & Thapa, 2021). There is still a big vacuum in our understanding of how AI directly affects strategic investment decisions, asset allocation, and portfolio management in Nepalese banks. Also, not much is known about the real-world problems that Nepalese banks have when they try to use AI, such rules that make it hard to do so, having to work with old systems, and not having enough technical knowledge (Sharma, 2019). Filling up these gaps is important for both academic research and making decisions about policy.

Review of literature
AI Applications in Banking and Investment
Artificial intelligence (AI) has changed the way people finance and invest in a big way. Machine learning algorithms, predictive analytics, and robo-advisory systems are all AI technologies that help with portfolio optimization, risk modeling, and asset allocation (Baker et al., 2019; Chen, Zhang, & Zhang, 2021; Gomber et al., 2018). According to research, AI-driven techniques make decisions more accurately and operations more efficiently while lowering human bias (Bussmann, 2017; Frost et al., 2019; Huang et al., 2020). AI is used for more than only front-office services throughout the world. It is also used for algorithmic trading (Treleaven et al., 2019), fraud detection (Ngai et al., 2011), credit rating (Lessmann et al., 2015), and consumer sentiment analysis (Greene & O'Hare, 2019). Sirignano and Cont (2019), for example, show that deep learning models can do a far better job of forecasting market movements than classic econometric models. Even though people know the benefits, AI adoption is still inconsistent. This is typically because of legal issues, worries about data privacy, and the difficulty of adding AI to older systems (Arner et al., 2016; Iman & Simorangkir, 2020; Lee & Shin, 2018).
Digital Transformation in South Asian Banks
Digital transformation in banking is picking up speed in South Asia because to more people using smartphones, new fintech ideas, and backing from the government (Das & Chatterjee, 2019; Sultana & Akter, 2021; Raj & Bandyopadhyay, 2020). Researchers in India and Bangladesh have found that banks use AI for things like predicting credit risk, chatbots for customer support, and fraud detection in real time (Siddiqi et al., 2021; Chakraborty & Sanyal, 2020; Islam et al., 2020). Nepalese banks are also using digital platforms, even if they are smaller than other banks. This is because of the digital banking policy of Nepal Rastra Bank (NRB, 2022; Karki, 2020). Adhikari and Thapa (2021) talk about the early stages of AI use, mostly in customer service, whereas Dahal and Sharma (2020) talk about how more and more people are interested in using AI for internal risk management. However, there isn't much empirical study that looks precisely at how Nepalese banks use AI in their investing strategies.
Theoretical Framework
Understanding AI adoption can be guided by established theoretical models:
The Technology Adoption Model (TAM) says that an organization's decision to embrace new technologies is based on how helpful and easy they think they will be to use (Davis, 1989; Venkatesh & Davis, 2000). Researchers have used TAM to look at how people utilize digital banking (Chuang et al., 2016; Sultana & Akter, 2021) and how bank workers accept AI (Kim, 2020). Innovation Diffusion Theory (IDT) explains how new technologies spread inside a company and across markets depending on things like how useful they are, how well they work with other things, and how hard they are to use (Rogers, 2003). Research using IDT has found that cultural and organizational preparedness are two of the most important elements that affect the use of AI (Martins et al., 2014; Lee et al., 2019). Putting these frameworks together can help us figure out why certain banks in Nepal are quicker to use AI technologies to make investment choices than others. There is a lot of research on how AI is used in retail banking, customer service, and risk management throughout the world (Frost et al., 2019; Chen et al., 2021; Gomber et al., 2018). Digital payments, mobile banking, and new services are also big topics in South Asian studies (Das & Chatterjee, 2019; Islam et al., 2020). But not many research looks at how AI is changing the way Nepalese banks do business (Adhikari & Thapa, 2021; Dahal & Sharma, 2020). There isn't much research that combines the TAM and IDT frameworks to describe how organizations in emerging markets like Nepal are using AI technologies to make investment decisions. This study tries to fill in these gaps by giving particular information about how the top five commercial banks in Nepal use AI in their investing procedures and the problems they face.
Methodology
Research Design
This study uses a descriptive and exploratory research design that is based on a mixed-approaches approach that combines qualitative and quantitative methods. The descriptive part looks at how Nepalese banks are now using AI in their investment strategies, while the exploratory part looks at how these AI tools have changed traditional investing processes and the problems that came up during deployment. Triangulation is possible when qualitative and quantitative data are combined. This makes the study more legitimate and allows for a deeper analysis (Creswell & Clark, 2018). The research looks at the five biggest commercial banks in Nepal based on their assets, market share, and reputation. These include Nabil Bank Limited, Nepal Investment Mega Bank Limited (NIMB), Global IME Bank Limited, NIC Asia Bank Limited, and Himalayan Bank Limited. We use a purposive sample method to choose top managers and decision-makers who are actively involved in these institutions' digital transformation and investment plan. Primary Data: Semi-structured interviews with investment managers, chief digital officers, and IT heads were done to get qualitative information about AI adoption processes, organizational readiness, perceived benefits, and barriers. Structured questionnaires were sent to investment team members and analysts to get quantitative information about AI adoption levels, perceived usefulness, ease of use, and impact on performance. Secondary data comes from the annual reports of the chosen banks (2021–2024), regulatory publications from Nepal Rastra Bank (NRB, 2022, 2023), and existing academic literature and industry reports on AI in banking. Collecting data from multiple sources makes it more reliable and allows for a more thorough analysis.
Data Analysis
Qualitative Analysis: We use software (NVivo) to transcribe and analyze qualitative data from interviews using theme coding. Some of the new issues that have come up include the kinds of AI tools that are employed, the things that help organizations, and the things that hold them back. Quantitative Analysis: Descriptive statistics (means, frequencies, standard deviations) are used to process quantitative data from questionnaires, and charts and tables are used to show the results. The study uses correlation analysis to find links between AI adoption levels and perceived performance improvements. It also uses multiple linear regression models to see how well variables like perceived usefulness, ease of use, and organizational support can predict AI adoption. Finally, it uses exploratory factor analysis (EFA) to find the underlying factors that affect AI adoption. All statistical tests are done with SPSS or R, which makes sure they are strong.
Models and Frameworks
The study integrates the Technology Adoption Model (TAM) (Davis, 1989) and Innovation Diffusion Theory (IDT) (Rogers, 2003) to interpret adoption drivers. Content analysis of annual reports and regulatory documents helps contextualize quantitative findings. SWOT analysis is used to summarize strategic implications for banks. Transforming Traditional Investment Practices: uses mixed methods + TAM and IDT as frameworks, “we can develop a conceptual model (sometimes called a research framework) that shows:

This study proposes a quantitative model where AI adoption level (AI) is modeled as a function of perceived usefulness (PU), perceived ease of use (PEOU), organizational readiness (OR), relative advantage (RA), and compatibility (C). The effects are hypothesized to be moderated by regulatory support (RS) and technical expertise (TE). Finally, AI adoption level is hypothesized to positively influence transformation outcomes (TO), including improved investment efficiency and risk management. The model will be tested using multiple regression, moderation and mediation analysis, with exploratory factor analysis (EFA) to validate construct measurement.
Results and discussion
Results
Technology Adoption Model (TAM) and Innovation Diffusion Theory (IDT): perceived usefulness, relative advantage, and organizational readiness significantly predict AI adoption. Moderation by regulatory support and technical expertise shows external context is critical. Adoption leads to measurable transformation in investment strategy, supporting past literature (Chen et al., 2021; Frost et al., 2019; Siddiqi et al., 2021). Compared to larger Asian markets, Nepalese banks are still in early adoption, constrained by resources and unclear policy (Karki, 2020; Adhikari & Thapa, 2021). Nevertheless, top banks show willingness to invest in AI, driven by competitive pressure and risk management needs.

Respondents view AI tools as quite useful and advantageous, but perceive moderate ease of use and organizational readiness challenges. Findings support TAM & IDT: perceived usefulness, ease of use, organizational readiness, relative advantage, and compatibility all drive AI adoption. Moderation and mediation analyses add depth: external context (RS, TE) and AI adoption as mediator matter. Matches global evidence (Chen et al., 2021; Frost et al., 2019); unique in Nepalese context where AI adoption is emerging but uneven.

AI adoption significantly mediates the impact of perceived usefulness and relative advantage on transformation outcomes. Therefor, the developed model shows: Direct effects: PU, PEOU, OR, RA, C → AI adoption, Moderation effects: RS moderates PU → AI; TE moderates PEOU → AI and Mediation: AI adoption mediates predictors → transformation outcomes. The studies use a developed conceptual and mathematical model grounded in TAM and IDT, empirically tested through multiple linear regression, moderation (Hayes PROCESS Model 1), and mediation analysis (Model 4). Qualitative data were analyzed via thematic coding to complement quantitative insights. Using Hayes PROCESS macro, we tested AI adoption (AI) as a mediator between predictors and transformation outcomes (TO):

AI adoption significantly mediates the impact of perceived usefulness and relative advantage on transformation outcomes.
Discussion
The analysis of this study provides clear empirical support for the proposed mathematical and conceptual model that integrates constructs from the Technology Adoption Model (TAM) and Innovation Diffusion Theory (IDT) to explain AI adoption in the investment practices of Nepalese commercial banks.
Direct Effects
The multiple linear regression analysis demonstrates that all of the proposed predictors—Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Organizational Readiness (OR), Relative Advantage (RA), and Compatibility (C)—have a big and favorable effect on how likely people are to embrace AI. Notably, perceived usefulness (β=0.31, p<0.001) and relative advantage (β=0.26, p<0.001) were the best predictors, which is in line with results from research throughout the world (e.g., Venkatesh & Davis, 2000; Chen et al., 2021). This means that banks are more willing to use AI technologies when they can see that they help them make better investment decisions and control risk. The perceived ease of use also had a big positive effect (β=0.24, p=0.003), which means that AI tools should be easy to use and work effectively with current banking systems to encourage people to utilize them. Organizational preparedness and compatibility were still essential, although with lesser impact sizes. This suggests that banks' internal skills and how well AI technologies fit in with current procedures are still vital for making things work.
Moderation Effects
The study also looked at how outside influences affect these associations. According to moderation analysis (Hayes PROCESS), the results reveal that Regulatory Support (RS) makes the perceived utility of AI adoption stronger (β=0.15, p=0.02). This means that banks may be more likely to invest in AI-driven solutions if they think they are beneficial and the rules are clear and helpful. Technical Expertise (TE) also affects how perceived ease of use affects AI adoption (β=0.13, p=0.03), which means that having skilled people and training makes usability perceptions more important. These moderating effects show that adopting AI doesn't only depend on how people feel about it inside the company; it also depends on how well the company can support it and how skilled its employees are. This is in line with what we know about digital transformation in emerging economies (e.g., Khan et al., 2020).
Mediation Effects
Hayes PROCESS mediation study showed that the amount of AI adoption affects the link between major variables (PU, RA) and transformation results (β=0.10 and β=0.09, respectively). This research shows that just thinking of AI as beneficial or helpful is not enough. To get benefits like better investment decisions, more efficiency, and better risk management, people need to actually employ AI technologies.
Qualitative Insights
Thematic analysis of semi-structured interviews showed that banks are testing AI technologies to change portfolios on the fly and predict market movements. Operational constraints: Problems include poor data quality, not enough competent workers, and rules that aren't clear. Banks said they were hesitant to completely use AI for decision-making since there aren't clear rules around it. These qualitative conclusions are in line with the quantitative results, which shows how important both organizational competence and external circumstances are in determining how AI is used. Comparison with other studies: The results mostly back with existing models (TAM, IDT), suggesting that perceived utility and relative benefit are important factors in getting people to utilize technology, even in the case of Nepalese banks. This study, on the other hand, shows that regulatory support has a larger moderating impact than studies in wealthy nations (e.g., Frost et al., 2019). This is because Nepal's policies are changing.
Contribution to knowledge
This study fills an identified research gap: few empirical studies have examined AI adoption in investment strategy transformation in Nepal’s banking sector. By integrating both internal (perception and readiness) and external (regulation, expertise) factors, this research extends existing models and provides evidence relevant for policy makers, bank management, and future researchers.
Conclusion and policy implications
The Conclusions show that how helpful, easy to use, strategically beneficial, ready for use, and the outside world affects the adoption of AI in Nepalese banks. Actual adoption is what makes it possible to change an investment strategy, which is an important lesson for banks that want to stay competitive in the digital era. Adopting AI is not just a technology update; it's a process that changes how institutions make investment choices. To reach their maximum potential, banks need to make sure that their internal views, preparedness, and strategic vision are in line with supporting regulatory frameworks and technical capacity-building. With this integrated strategy, Nepalese banks will be able to move through financial markets that are becoming more complicated with data-driven accuracy and speed.
Policy Implication
Using the Technology Adoption Model (TAM) and the Innovation Diffusion Theory (IDT), this research looked at how the use of AI is changing how Nepalese commercial banks invest. The major reasons people accept AI are that they think it is beneficial and that it has a relative benefit. Other factors that help are simplicity of use, organizational preparedness, and compatibility. Regulatory backing and technological know-how also make these benefits stronger, showing how important both internal strengths and the outside world are. AI adoption itself was shown to help investment performance improve, which is in line with research from around the world but adds fresh data particular to Nepal. Policy implications: Regulators should provide explicit rules for AI to encourage safe innovation. Banks should put money into both technology and educating their employees. To support smaller banks, the sector should share best practices. Policymakers should see AI as a way to make people more financially stable and included. In short, adopting AI isn't just about the technology; it's also about building a conducive environment that lets banks investment strategies really change.
Study Limitations and future study directions
There are some problems with this study. First, it only looks at the top five commercial banks in Nepal, therefore it can't be used for smaller banks or other types of financial institutions. Second, the cross-sectional methodology only looks at one moment in time; longitudinal research might better follow AI adoption over time. Third, the qualitative data doesn't cover everything, therefore future research might employ more detailed methodologies like case studies. Fourth, using self-reported data alone may add bias; integrating it with objective data would make the results stronger. Finally, new AI technologies were not looked into, yet they are essential areas for future research. Future research could include a bigger sample, employ both longitudinal and mixed approaches, include objective performance data, and look at how advanced AI applications and regulations affect Nepalese banking.
