Abstract: This article examines the emerging landscape of geoeconomic competition and its profound implications for organizational leadership. As geopolitical tensions reshape global markets through trade restrictions, investment controls, and technology decoupling, business leaders face unprecedented complexity in strategic decision-making. Drawing from international relations scholarship, strategic management literature, and documented organizational responses, this analysis provides a framework for understanding market fragmentation and its consequences for multinational enterprises. The article identifies evidence-based leadership approaches for navigating geoeconomic tensions, including strategic foresight capabilities, supply chain resilience measures, stakeholder management strategies, and regulatory navigation frameworks. By developing organizational capabilities in geopolitical intelligence, scenario planning, and adaptive governance, leaders can transform geoeconomic challenges into sustainable competitive advantages while mitigating risks in increasingly fractured global markets.
