The battle for monetary hegemony: The end of the dollar or a new Multipolar order?

The dollar as a weapon and its challenge. The hegemony of the U.S. dollar, consolidated after the 1944 Bretton Woods Agreements, has been the cornerstone of the global financial order for nearly a century. However, its growing use as a tool of geopolitical pressure —materialized in economic sanctions that can isolate entire countries from the global financial system— has sown the seeds of its own decline. The recent threat by the United States to expel from the dollar system any country that trades with Iran, under the so-called "Operation Economic Outcast," is a clear example of how Washington uses its currency as a weapon, but also a catalyst that pushes other nations to seek alternatives.

The threat that reveals vulnerability. The warning by U.S. Treasury Secretary Scott Bessent that "no country is beyond reach" of being excluded from the dollar system if it maintains ties with Iran, including China, has had a paradoxical effect. Instead of deterring, it has accelerated the search for a parallel financial architecture. Countries like Russia, Iran, and the members of the BRICS bloc perceive that dependence on the dollar is an existential risk to their sovereignty and have begun building defense mechanisms, from alternative payment systems to reserves diversified in gold and other currencies.

The scenario of a U.S. isolation: Reality or fiction?. A total economic isolation of the United States by the rest of the world is an extreme scenario, but its mere speculation reveals the fragility of the system. If countries coordinated a boycott of the dollar, the consequences would be devastating for both sides: for the U.S., a massive depreciation of its currency, imported inflation, and a collapse in its debt financing; for the world, a fragmentation of global trade and financial chaos. However, current interdependence and the lack of liquid alternatives make this scenario unlikely in the short term, although its possibility is increasingly gaining ground in academic and geopolitical debate.

The BRICS as the engine of De-dollarization. The BRICS bloc, which represents more than 40% of the world's GDP in purchasing power parity and controls a significant share of the planet's energy and agricultural resources, has positioned itself as the main counterweight. Its most ambitious project is the development of a parallel financial infrastructure that includes BRICS Pay (an alternative to SWIFT), the digital currency bridge (BRICS Bridge) , and the BRICS Clear platform. Furthermore, the proposal for a digital trade currency backed 40% by gold and 60% by a basket of national currencies, called "The Unit," symbolizes an attempt to create a system that does not depend on the dollar or Western institutions.

Strategies to reduce U.S. influence and shield against sanctions. To protect themselves from sanctions, countries are implementing multiple strategies: they promote bilateral trade in local currencies, increase their gold reserves, diversify their holdings of U.S. debt, and strengthen alliances with other Global South nations. Domestically, some nations have enacted "anti-boycott" laws that prohibit their companies from complying with foreign sanctions they consider illegitimate, and have created their own clearinghouses to settle transactions without going through the U.S. system. These measures, although fragmented, seek to create an "immune system" that reduces collective vulnerability.

The Time factor: How long until the end of the dollar?. Projections about the end of the dollar's hegemony vary drastically. Some analysts, like Marc Faber, foresee a major shift within the next decade; others, like those at JP Morgan, estimate that its dominance could last four more decades. Most agree that the process will be "slow and uneven," and that the outcome will not be the collapse of the dollar, but a transition to a multipolar monetary system where the dollar, the euro, the yuan, and other regional currencies coexist. The speed of this change will depend on factors such as U.S. debt management, the success of alternative systems, and the cohesion of blocs like the BRICS.

Gold as a shield and its limits. Gold has reemerged as a key safe-haven asset in the de-dollarization strategy. Its physical nature makes it immune to seizures and freezes, which is why sanctioned countries like Russia and Iran actively use it to circumvent restrictions. However, a return to the classical gold standard is unfeasible; the available supply of gold is insufficient to back the global economy, and such a system would cause deflation and monetary rigidity. Therefore, the current approach is hybrid: gold acts as an anchor or reserve cushion, but not as the exclusive basis of the monetary system.

The euro: The "eternal second" That never quite takes off. The euro, with a stable 20% share of global reserves, remains the second most important currency, but it has failed to seriously challenge the dollar. Its structural weaknesses —lack of a common safe asset (Eurobonds), fragmented capital markets, and the absence of fiscal integration— prevent it from competing on equal footing. As ECB President Christine Lagarde noted, the euro will not gain influence "by default" but "will have to earn it." As long as Europe does not complete its capital markets union and issue joint debt, the dollar will maintain its advantage.

The Achilles' heel of the U.S.: Debt and treasury bonds. The greatest risk to the dollar's hegemony does not come from its rivals, but from its own fiscal fragility. U.S. debt exceeds $40 trillion, and annual interest payments already surpass $1 trillion. If major foreign holders of Treasury bonds (China, Japan, etc.) reduced their purchases or began to sell, bond yields would soar, making government financing more expensive and triggering a confidence crisis. Although the Federal Reserve can "print money" to buy bonds, this measure would fuel inflation and further erode the dollar's long-term credibility.

A multipolar world, not an end to the dollar. The dollar's hegemony will not come to an abrupt end, but its monopoly is eroding irreversibly. The world is moving toward a multipolar financial system where the dollar will be an important currency, but not the only one. U.S. sanctions, far from strengthening its position, are accelerating the search for alternatives, driving the creation of parallel financial infrastructures and the resurgence of gold as a reserve pillar. The key to this transition will not be collapse, but the coexistence of multiple systems, and its success will depend on the ability of global actors to build more inclusive, resilient institutions that are less dependent on the will of a single power.
