This study explores the intricate relationship between financial markets and sustainable economic development, aiming to elucidate the dynamics, challenges, and opportunities at the intersection of finance and sustainability. Employing a multidisciplinary approach, the research synthesizes insights from economics, finance, environmental studies, sociology, and political science to provide a comprehensive analysis. The purpose is to examine how financial market activities influence the pursuit of sustainable economic development and vice versa. Methodologically, the study employs a literature review to synthesize existing research and identify gaps in understanding. Findings reveal that while financial markets play a crucial role in capital allocation and resource mobilization, they also pose challenges such as environmental degradation, social inequality, and systemic risks. Regulatory frameworks and institutional arrangements are identified as critical factors shaping the impact of financial markets on sustainability outcomes. The discussion highlights the need for a holistic approach that integrates financial market reform, regulatory enforcement, and stakeholder engagement to address these challenges. Implications include the importance of aligning financial incentives with sustainability objectives, enhancing the resilience of financial systems, and fostering collaborative partnerships among stakeholders. Overall, the study contributes to both theoretical understanding and practical insights for policymakers, practitioners, and scholars navigating the complex terrain of finance and sustainability.
