The world financial system is growing more volatile, and it is questionable whether the conventional reserve currencies will remain as strong as ever. This paper will look at whether the euro can meaningfully challenge the U.S. dollar’s dominance as increasing economic volatility and the appearance of new competitors like the Chinese Yuan raise this question. This paper uses a qualitative and descriptive-quantitative approach based on empirical data provided by the IMF and BIS alongside the contributions of the hegemonic stability theory, network effects, and institutional trust to study the dynamic nature of global reserve currencies. It determines the competitiveness, credibility, and limitations of key reserve currencies. The results indicate that the dollar has fallen from above 70 per cent of the world reserves to approximately 58 per cent as at mid-2024. The euro has retained a consistent portion of about 20 per cent of the world reserves, with strong legal systems and effective monetary policy, but its expansive impact is limited by the fractured fiscal system and political disintegration of the Eurozone member states. The Yuan holds approximately 4 per cent of the global reserves. Despite China’s financial influence is increasing globally, the international role of the Yuan remains limited because of China’s capital controls, managed exchange rates, and financial transparency issues. This paper concludes that there is no single currency that will take the lead in the future. Rather, the world is becoming multipolar in terms of reserve systems where the dollar, euro, Yuan, and selected digital currencies co-exist.
