Economic Hegemony is a rigorous examination of how global power is exercised in the modern world-not primarily through military force, but through rules, institutions, and economic systems that appear neutral while producing durable inequality. Drawing on history, law, finance, trade regimes, technology, and global governance, the book explains how dominant states and economic blocs shape the architecture of the global economy in ways that systematically advantage themselves and constrain the sovereignty of weaker nations. From colonial extraction to postwar financial institutions, from debt diplomacy and sanctions to technological standards and cultural influence, economic dominance is shown to be structural rather than accidental. Through detailed case studies involving the United States, China, the European Union, and the Global South, Economic Hegemony reveals how trade agreements, financial conditionality, regulatory power, and institutional design operate together to lock in asymmetry-often without overt coercion. The book also examines the human consequences of these systems, including underdevelopment, inequality, political instability, environmental degradation, and constrained policy autonomy. This is not a polemic, nor a theoretical abstraction. It is a systematic account of how power actually functions in the global economy-and why understanding that structure is essential for any serious discussion of sovereignty, development, and global justice in the twenty-first century.
