BRICS vs Dollar: The Battle for Reserve Currency Dominance

For eight decades, the US dollar has functioned as the world's reserve currency — the default medium for oil contracts, sovereign debt, and international trade settlement. That dominance was never simply economic. It was enforced by alliance networks, military presence, and the absence of a credible alternative. BRICS, the expanding bloc of Brazil, Russia, India, China, and South Africa, now represents the most serious collective challenge to dollar primacy since Bretton Woods. This book examines the BRICS challenge not as an imminent dollar collapse, but as a structural shift decades in the making. It traces how US sanctions policy — particularly against Russia after 2022 — accelerated the search for dollar alternatives among nations that feared their own reserves could be frozen. It follows the quiet expansion of yuan-denominated oil contracts, bilateral currency swap agreements, and the technical groundwork being laid for a BRICS payment system that bypasses SWIFT entirely. Drawing on central bank data, trade agreement analysis, and geopolitical scholarship, this is a rigorous account of how monetary power is contested — and what a multipolar currency system would mean for global governance, commodity markets, and ordinary economies caught between competing financial blocs.
