A B S T R A C T The study aimed to identify the relationship between the investment actuary, geopolitical risks, and banking risks by applying to the Sudanese banking sector, through a survey study on selected sample of private Sudanese banks, and test whether the investment actuary mediates the relationship between geopolitical risks and banking risks. The study found the presence of the investment actuary in the banking sector supports improving performance, assists in predicting risks and creating a balance between returns and risks, it efficiently contributes to improving the management of investment portfolios in the face of uncertainty caused by geopolitical risks, also the study revealed there is strong statistically significant relationship that confirms the investment actuary's mediating role in the relationship between geopolitical risks and banking sector risk Keywords: Investment Actuary - Geopolitical Risk - Banking risk INTRODUCTION: In many countries the economic sector faces various risks and basic threats that hinder the work of development and openness to global markets, as these risks have become a basic feature of third world countries, these risks affect all sectors of the economy, and the most affected sector is the banking because of its significant contribution to economic activity, as it is the main channel for the flow of capital from financiers, clients and beneficiaries. Among these services, as well as employing and accumulating savings and directing them towards investment in various economic projects in a manner consistent with achieving mutual benefits. Therefore, evaluating the performance of the banking sector and verifying its efficiency has become a strategic issue in order to enhance the effectiveness and flexibility of the financial system as a whole, especially in the face of financial and economic shocks. This vital sector is fraught with increasing risks due to complex and ongoing geopolitical obstacles, especially in a country like Sudan that constantly suffers from geopolitical fluctuations that have created a turbulent economy that suffers from these fluctuations. These geopolitical risks contributes to creating severe economic fluctuations that paralyzed the Sudanese economy and prevented it from developing and continuing to grow. We find that many researchers have indicated that geopolitical risks are a way to study and understand the geographical and political variables that are consistent with foreign policy and predict international behavior and relations between countries, which may be represented by climate changes. Politics and frankness between Baddan and international crises, (Wade 2019), (Caldara and Iacoviello 2019), Khalid, W.E.O. (2020), Biswal (2016) Khalid, W.E., et al. (2023), Yang (2021). In light of these geopolitical risks and fluctuations, which become a basic nucleus of banking risks, we find that the banking sector essentially seeks to rely on strategies that help it deal with these risks and fluctuations, and the most prominent of these strategies is relying on actuarial science. Which is often considered to be a portion of the business field, which encompasses a wide range of fields that are interconnected such as mathematics, economics, statistics, accounting, finance, and probability. (Jugu, 2015). with another side we find an investment actuary according to Sharma (2019), he is defined as a financial expert who relies on actuarial and financial principles to manage or analyze investment portfolios and assets, taking into account the liabilities and financial risks or contingencies, he also enhances the predictive roles of risks and identifies the negative effects that they can have. (Reynolds, 2021), (Johnson, 2002), (Khalid, W.E.O. 2020), and (Khalid, W.E., et al. 2023). While another hand when we discuss on banking risk in the context of this study, we found there is no concept of banking risk has a single accepted definition, so we can define the Risks in banking as mentioned Sî rbulescu, C. (2016) a chance wherein an outcome or investment’s actual return differs from the expected returns. As a complex of events with adverse consequences for the bank, an outcome or investment’s actual return differs from the expected returns. This study attempts to shed light on the contributions made by actuarial science in enhancing dealing with banking risks, by identifying the role of the investment actuary in dispelling fears about risks and helping to predict them. Therefore, the study seeks to identify the roles that the investment actuary can provide in light of these risks, which are clearly represented by banking risks and geopolitical risks, and how to increase investor confidence
