This review article examines the strategic evolution of global power dynamics, arguing that financial instruments have supplanted nuclear arsenals as the primary levers of geopolitical influence. By analyzing the soft power initiatives of the United States (USAID), China (Belt and Road Initiative), and the European Union (Global Gateway), this article traces the convergence of these distinct economic models toward militarized tools of governance. While traditional narratives contrast Western “liberal conditionality” with Chinese “non-interference,” recent evidence suggests a functional convergence where all three actors use financial triggers, grants, loans, and investment frameworks, to shape governance and human rights standards in recipient nations. This study synthesizes recent literature to demonstrate how the shift from nuclear deterrence to financial coercion is redefining sovereignty in the Global South, ultimately questioning whether these competing financial architectures truly promote human rights or simply impose new forms of hegemonic conformity.
