The main objective of this research is to investigate the relationship between working capital managementand the profitability of banks in the Iranian capital market. To achieve this objective, financial data from thirteen banks have been used in a balanced panel format over the period from 2013 to 2021.

In this research, hypothesis testing has been carried out using fixed-effect regressions and Generalized Method of Moments (GMM) estimations. The results indicate that there is no significant relationship between the cash ratioand profitability, while there is a positive and significant relationship between the CCC and profitability

This study aims to investigate Saudi Arabia’s quest for regional hegemony, including its objectives, initiatives, and difficulties. In other words, the degree to which Saudi Arabia has been successful in establishing itself as the region’s dominant power. It is crucial to thoroughly explain Saudi Arabia’s psychological and practical justifications for pursuing regional hegemony in this context. To examine the political discourses, reality, narratives, ambitions, and perspectives of Saudi Arabia and compare these with other regional powers in this area, as well as to highlight a number of context-specific constraints on Saudi Arabia’s aspirations for regional hegemony, is the goal of the research. In addition, it intends to investigate how external powers such as the United States, China, Russia, the European Union, and Turkey influence Middle Eastern regional dynamics based on their own vested interests. This analysis demonstrates that Saudi Arabia’s drive for regional hegemony is mostly restrained by external causes. First, despite its preeminent economic power, the country lacks strong military capabilities to provide a security shield for its friends in this region. Second, the sectarian politics and undiversified economy of the region make it unlikely that secondary nations will receive full public goods. Third, low economic integration, the perception of a common regional threat, the absence of a broad free trade arrangement, the superiority of hard power over soft power, and a lack of mutual trust among regional countries are significantly diminishing the acceptance of Saudi Arabia’s hegemonic role in the region. However, Saudi Arabia is deliberately involving regional partners and coalitions in regional growth. The country takes on the main task for reshaping the Middle East’s economy and elevating this region to success. If Saudi Arabia is successful in fostering regional integration, offering a security shield, encouraging trust building, and collaborating with other states in this region to address shared regional threats, it will have a greater chance than the majority of other states in the region to become the regional hegemon.
