The Future of the Dollar as Reserve Currency

The US dollar is the most extensively owned and utilized reserve currency in the world's financial system, with major implications for international commerce, investment, and monetary policy. Accounting for approximately 90% of all foreign exchange transactions, it is a pillar of economic stability for many countries that depend upon it to sustain their currencies and economies. The Bretton Woods Conference established the United States dollar as the world's reserve currency in 1944, in the aftermath of World War II, providing a stable framework for international trade and investments, thereby cementing the U.S. dollar's prominent role in the global economy, with significant quantities held by central banks and other major financial institutions to facilitate international trade and stabilize exchange.The dollar's ascendancy marked a transition from the British pound sterling, which served as the dominant reserve currency from the mid-19th century until World War II. This historical precedent demonstrates that reserve currency status can shift, though such transitions typically occur over decades rather than years. 

How did the Dollar become the leading currency? 

1. Liquidity of the financial market and Economical strength

One of the prominent reasons contributing to the dominance of the U.S. Dollar in the global trading market is its stable liquidity. As is well-established, the US treasury market proceeds to be the globe's largest and most liquid. Its rapid currency conversion into other monetary units renders it highly simple to use internationally. The more extensively the dollar is being utilized, the broader its network becomes, the more entrenched it expands, and the more costly it is for anyone to sustain themselves with it. Furthermore, the United States has a diverse economy and strong political institutions, which contribute to its stability in the currency’s value when facing sudden shifts in domestic currency due to financial disturbance or economic recession, which has further enhanced the demand for the U.S. dollar.

2. Petrodollar trading system

Petroleum is one of the most significant commodities in international trade, and it is predominantly sold and purchased in US dollars, with both oil producers and consumers relying on the petrodollar system for commodity transactions, despite BRICS nations' as well as China's efforts to diversify pricing mechanisms. The petrodollar system is a significant source of revenue for many Organization of Petroleum Exporting Countries (OPEC) members, whereas oil producers, including Saudi Arabia, the world's largest oil exporter, accept US dollars as payment due to their exchange rate stability and the size of the US economy. According to the Energy Information Administration (EIA), global crude oil production is expected to be approximately 76.51 million barrels per day (bpd) and is predicted to rise to 78.28 million bpd in 2025, with the major increase in oil production from the non-OPEC countries the United States, Guyana, Canada, and Brazil. It is predicted by the EIA to increase by 1.2 million bpd in 2025 and by 0.6 million bpd in 2026, with the assumed average price of $85 per barrel. 

3. Military power

Although the United States’s military power doesn’t directly support the dominance of its currency, through its effective efforts in exporting security through its military presence worldwide, the US’s allied nations benefit from the security provided by the US; these countries are therefore holding the U.S. Dollar as their reserve currency, which reinforces the Dollar’s global position as the top currency. In an article published in 2024 by Columbia Business School, Professor Pierre Yared stated, “If you want a global store of value, you want an asset that will preserve its value in a cataclysmic state of the world”; therefore, a powerful military force is required to safeguard the value of a nation's assets, emphasizing the importance of military might in upholding the U.S. dollar’s role in international financial exchanges.

The “exorbitant privilege” of the United States

As the authority in charge of the world's reserve currency, the United States may readily borrow at low interest rates while other nations trade in dollars, raising the global appetite for the U.S. dollar and reducing U.S. borrowing rates, thereby helping to maintain a stable economy. The US dollar is commonly employed in international transactions, enabling the United States’ significant financial strength while additionally impacting the monetary policy of other countries.

Recent Trends and Challenges

Depreciation of the Dollar

Geopolitical dynamics are capable of having a significant effect on the value of the US dollar, typically resulting in depreciation via a variety of interrelated causes. In 2025, the Dollar has depreciated by approximately 9% due to several factors:

Trade Policies: Tariffs and Tax-Cut Bills

On April 2nd (Liberation Day), US President Donald Trump announced a minimum of 10% of “reciprocal tariff” on all US import goods from all countries to achieve the purpose of encouraging US consumers to use local goods, which has stirred up conflicts, putting the United States' currency in jeopardy. Countries in the European Union, for which Trump initially proposed a tariff of 20% and then halved it to 10% for discussion, and the tariff is postponed to increase to 50% by July 9; while the US dollar continues to decline, the value of the sterling has soared to its highest peak over the last three years, putting the UK in a better position than the present dollar fluctuation.

or the sharp rise of tariffs to 40% on China, Canada, and Mexico, which are also targeted by Trump. This frequent use of tariffs has posed uncertainty in international trade relations as many countries begin to diversify away from the US economy, which reduces the foreign demand for US assets, weakening the Dollar’s position. The high tariff rate on China has also caused disruptions to the global supply chains, which dampened international trade, resulting in a decline in the US currency as the transactions are carried out using the Dollar. With a 25% tax on imports being introduced on most imports, Trump has strained the traditional alliances, such as Canada, forcing the country to explore alternatives to the Dollar for international trading.

Additionally, after the downgrade to Aa1 from Aaa of the US’ Moody’s sovereign credit rating established on May 16, which has raised concerns at the US Treasury, the US House of Representatives have released President Donald Trump’s tax-cut bills, which are estimated to be $3.8 trillion, adding up to the existing $36.2 trillion debt of the US government over the past years. This reduction in Moody’s credit rating has further highlighted that the debt-to-GDP ratio of the US has exceeded 134%. As a result, the value of the U.S. Dollar; a typical instance would be the drop of the Dollar by 0.3% to 142.35 yen.

Fiscal Deficits

The escalated expenses of imported products have exacerbated fiscal deficits by adding to the rising inflationary strain on American consumers. By 2024, the US government's deficit expenditure will surpass its receipts by around $1.83 trillion. Additionally, interest on US debt is expected to surpass $1 trillion by 2024, raising worries among key surrounding nations and causing the Dollar to fall by 8% versus major currencies this has led to the erosion of confidence in US fiscal stability, threatening the position of the USD in the global trading system. The monetary power of the dollar to enforce fiscal penalties has prompted several governments to look for alternatives to decrease their vulnerability

Reallocation of Investors

In recent years, major investors such as China or Japan are reallocating themselves away from the US Treasury yields, mitigating the geopolitical risks. The historic correlation has proved that if the yields rise, it will attract foreign capital, and vice versa, therefore increasing the value of the Dollar; this results in the sharp decline of the U.S. currency. 

Central Bank Gold Purchases

Central banks have significantly stepped up gold purchases to hedge against dollar exposure. Central banks in 2024 have bought in excess of 1,000 metric tons of gold for the third year in a row, led by China, Poland, and central banks of emerging market nations. It is twice the historical norm and points to institutional activity to diversify away from standard dollar-denominated assets.

De-dollarization?

According to the euobserver on the 27th of May, 2025, President Donald Trump's trade aggressiveness has already ripped away billions from stock markets in recent weeks, sending the dollar down versus practically every major currency. While BRICS advancement offers alternative means of financing for Southeast Asian countries at present, US tariff policies have prompted substitution of currencies beyond dollar-dominated trade systems, thus making de-dollarization momentum escalate. “ASEAN nations are among those most heavily affected by the U.S.-imposed tariffs,” said Malaysia’s Foreign Minister Mohamad Hasan; therefore, they are working on reducing the reliance on the U.S. Dollar in international trading. Many ASEAN countries have recently adopted a funding structure that would, for the first time, use local currency, including the Chinese yuan, rather than the U.S. Dollar, which further contributes to the rising momentum of de-dollarization. BRICS nations, such as Iran and Russia, have completely abandoned the use of dollars in bilateral trade, instead opting for rubles and rials, as President Donald Trump's trade and foreign policies have forced these countries to reduce their reliance on the United States currency. Many countries would like to see an alternative to the U.S. dollar, as there is an emergence of alternatives such as the Euro or the Chinese renminbi (RMB), although they currently lack the infrastructure and trust that the USD commands, which the United States challenges the globe to meet. The BRICS nations have established BRICS Pay, a decentralized system of payments designed to facilitate transactions and conduct trades in local currencies, eliminating reliance on the US dollar or financial institutions such as SWIFT. However, dedollarization efforts face significant structural challenges. The dollar's 'network effects' create self-reinforcing demand: international contracts are priced in dollars, creating natural hedging needs; global commodity markets predominantly use dollar pricing; and the depth of U.S. capital markets remains unmatched. Alternative payment systems like BRICS Pay currently handle minimal transaction volumes compared to the $7.5 trillion daily forex market where the dollar dominates.

Can the Euro replace the Dollar?

Although the U.S. dollar has remained the leading currency worldwide, the present efforts to minimize dependency on the Dollar are gaining traction. As the world’s second-largest currency, there is an undeniable potential for the Euro to take the Dollar’s place. There has been an ongoing argument centering on whether the Euro can dethrone the U.S. Dollar to become the world’s top reserve currency. On the 26th of May, 2025, European Central Bank President Christine Lagarde indicated that there is a potential for the U.S. dollar to lose its dominant status, with the euro emerging as a viable alternative provided the European Union strengthens its financial systems and security framework. But the euro has institutional limitations that reduce its reserve currency status. The European monetary union has no single fiscal policy, and there is no single European sovereign bond market comparable to that of U.S. Treasuries. The euro area has a fragmented banking system and no real 'Eurobond,' offering structural disadvantages relative to the integrated U.S. financial system.

The Future of The Dollar

In accordance with the IMF's Currency Composition of Official Foreign Exchange Reserves (COFER) survey, the share of dollar holdings in allocated global reserves increased slightly from 57.30% to 57.80% in the third quarter of 2024 as other major reserve currencies depreciated against the US dollar. Despite this short-term increase in Q4 2024, the long-term trend remains concerning: the dollar's share of global reserves has fallen significantly from around 70% by an estimated 17% over the last two decades.

Multiple scenarios could unfold: Gradual Decline (15-20 year timeline) where the dollar's share slowly erodes to 45-50% while no single alternative emerges; Bipolar System where dollar and yuan/euro divide major regions; or Continued Dominance if the U.S. addresses fiscal challenges and maintains technological/military leadership. Most economists view rapid displacement as unlikely given the massive coordination required to replace incumbent systems, even as gradual diversification continues.

Market Reality Check

Despite dedollarization hype, market facts show the dollar's ongoing centrality. Cross-border yuan payments are under 3% of global figures; the majority of 'non-dollar' transactions are still converted into dollars somewhere along the way; and in 2025's market upheaval, investors ran to dollar assets, again affirming its enduring safe-haven status. The disparity between political posturing to alternatives and hard infrastructure in markets remains large.

Conclusion

Despite many countries’ discomfort with the dominance of the Dollar, as well as the decline of the Dollar in reserve currency allocation compared to a decade ago, the currency is still holding a significantly higher percentage compared to the 20% share of the Euro in the fourth quarter of 2024 due to the United States’ stable liquidity, its economic strength, and the gradual rate at which the allocation of monetary authority shifts will secure the dollar as the world’s dominant reserve currency in the foreseeable future. The U.S. dollar also has legitimate long-run challenges from fiscal imbalances, geopolitical tensions, and conscious diversification. Yet, replacing a reserve currency does not simply take political will, but enormous infrastructure development, institutional trust establishment, and coordination across multiple rival economies. While the share of the dollar can continue to fall gradually, replacement could occur over decades instead of years with far-reaching consequences to the stability of global finance in any transition. The end result depends on alternatives gaining the depth, liquidity, and institutional frameworks that today make the dollar irreplaceable to global commerce.
