In today’s rapidly changing corporate environment, effective leadership is no longer optional but a requirement for organisational success. Focusing on the banking sector in Oman, this study examined how transactional, transformational and situational leadership, are influential in the effective realisation of organisational goals. As leadership becomes increasingly important for managing change and improving performance, it is important for practitioners and policymakers to understand these styles. An administered survey on samples collected from 56 employees from different banks in Oman is analysed. According to the findings, transformational leadership shows the most positive influence on employee motivation and long-term accomplishments, followed by transactional leadership, which enhances short-term performance and operational efficiency. The study also concludes that there is no single leadership style that will withstand the test of time, but a perfect balance and flexibility in that style will go a long way in determining the success of an organisation. The study highlights leadership development strategies, which are necessary in accordance with organisational goals and local cultural environments.
