USD hegemony, bitcoin, Central Bank Digital Currency and the geopolitics of money

Since World War II, the US dollar (USD) has substantially increased its prominence in international financial systems, culminating in its position as the predominant currency, facilitating approximately 90% of global foreign exchange transactions. The reliance of most nations on the USD for international trade - particularly for oil, commodities, and other goods - has cemented its critical role in global finance and geopolitics. Hence, the usage of the USD supported and forged an economic and geopolitical function for the emitting country, the United States of America. The geopolitical implications and risks related to the USD hegemonic power in trade and financial transactions have become increasingly more striking, especially in recent decades and years. The sanctions imposed on Venezuela, Iran and more recently on Russia via the US dollar-dominated SWIFT payment system highlighted the potential threat posed by the USD hegemonic power in the global monetary system. However, in the new millennium, alternative digital currencies have begun to exert influence and have implicitly and explicitly posed a threat to that hegemony. Bitcoin and other cryptocurrencies, for instance, have enabled international transactions without reliance on USD use. Additionally, the emergence of several multi-currency Central Bank Digital Currencies (CBDCs) would allow nations to conduct cross-border payments using various currencies without passing through the USD as an intermediary. Our paper explores the geopolitical implications of USD use on the international stage and examines the potential opportunities and threats posed by these new digital currencies for countries.
