Since the WWII, the USD significance has grown substantially within the international transaction framework, finally establishing itself as the predominant currency worldwide. Most nations have relied on the US dollar for purchasing commodities and services on the international market, thereby reinforcing the USD currency's vital role in the global arena. Hence, the USD use supported an economic and geopolitical function for the emitting country, the USA. The geopolitical implications and risks related to the USD hegemonic power in trade and financial transactions have become more striking with the sanctions imposed on Venezuela, Iran and more recently on Russia and China. However, in the new millennium, alternative digital currencies have begun to exert influence and have implicitly and explicitly posed a threat to that hegemony. 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.
