Recent military interventions by the United States, particularly under the aegis of Donald Trump’s administration, have catalysed a significant and complex shift in the international monetary landscape. The ongoing strikes against Iran, branded as Operation Epic Fury, have not only escalated tensions in the Middle East but also contributed to a growing perception of the US operating outside established global norms. This development is reshaping the dynamics surrounding the dollar’s dominance in global trade and finance.
The Decline of Dollar Dominance
The trade-weighted value of the US dollar has experienced a notable decline, dropping 7% over the past year, despite the country enjoying robust economic growth and buoyant stock markets. This depreciation is indicative of multiple factors, including inflationary pressures and rising interest rates, but it also reflects an increasing uncertainty regarding the reliability of US economic policies. As highlighted during a recent conference in London organised by the Centre for Inclusive Trade Policy, experts foresee a transition towards a more multipolar currency system rather than a singular replacement of the dollar akin to the post-World War II shift from the pound sterling.
Currently, the dollar remains the predominant currency for international trade transactions, yet the ascent of the Chinese renminbi is a noteworthy trend that Beijing is actively promoting. In the realm of foreign currency reserves, global central banks have gradually shifted their holdings away from the dollar, with its share plummeting from 71% in 2001 to just 57% by the end of last year.
Weaponised Interdependence and Economic Sanctions
The leverage that the US wields through its currency has been starkly illustrated during recent geopolitical events. The Federal Reserve’s actions in response to the 2007-08 financial crisis, which included establishing swap lines for select countries, exposed the global reliance on the dollar as the backbone of international finance. This reliance, however, has also fostered a growing wariness among other nations regarding the potential for economic sanctions and the ‘weaponisation’ of financial systems.

Mark Carney, former Governor of the Bank of England, articulated these concerns at the recent Davos summit, suggesting that large nations are increasingly utilising economic integration as a tool of coercion, exploiting tariffs and financial infrastructures to exert influence.
The Rise of Alternatives
The push towards de-dollarisation is gaining momentum, spurred by the advent of technological advancements that facilitate quicker and cheaper settlement systems. The European Central Bank’s recent decision to enhance its repurchase agreements is one facet of this growing trend, signalling a commitment to act as a lender of last resort to bolster the euro’s stability in times of crisis.
Alejandro Fiorito from The Conference Board notes that both China and Europe are proactively investing in digital currencies and financial mechanisms that allow them to reduce their dependence on the dollar. The BRICS nations—Brazil, Russia, India, China, and others—are also exploring frameworks to bypass US financial systems, discussing concepts such as a joint currency or interoperable central bank digital currencies.
Implications for the United States
For the US, the implications of reduced dollar dominance could be profound. Research from the Federal Reserve Bank of St. Louis indicates a “notable” decline in the convenience yield of US Treasuries, which historically has allowed the government to borrow at lower costs due to the dollar’s status as a safe asset. This trend, combined with soaring deficits and rising national debt projected to reach 130% of GDP within five years, poses significant risks to the US economy.

While US Treasuries continue to be seen as a safe haven during times of uncertainty—evidenced by falling yields amidst market volatility—the long-term trajectory suggests that the nation must adapt to a landscape where its financial supremacy is increasingly contested.
Why it Matters
The evolving relationship between global currencies and the diminishing role of the dollar is not merely an economic concern but a geopolitical one. As nations seek alternatives to US financial dominance, the implications for global trade dynamics, economic policies, and international relations could be transformative. The US, facing a future where its economic influence may wane, could experience heightened instability as it grapples with the consequences of a multipolar currency world. Understanding these shifts is essential for stakeholders across the globe as they navigate an increasingly complex financial landscape.
