Twice in the last century, the global financial system was forced to reinvent itself because the machinery underpinning money could no longer bear the weight placed upon it. The collapse of the gold standard during the Great Depression and the end of Bretton Woods in the early 1970s were not merely technical adjustments; they were systemic ruptures driven by shifts in power, trade, and capital flows. Today, the world stands at the edge of another such transformation. This time, however, the challenge is not centered on exchange-rate regimes or gold convertibility, but on digital infrastructure: the rails on which money itself now moves.

At the heart of this transformation lies a deceptively simple question: will the dominance of the US dollar survive the rise of digital money? Stablecoins, tokenized deposits, and central bank digital currencies (CBDCs) are rapidly reshaping how value is issued, transferred, and settled. Unlike previous transitions, this shift is not being negotiated through grand diplomatic conferences or formal treaties. It is unfolding from the bottom up, driven by technology, private innovation, and geopolitical competition over standards and systems.

To understand what is at stake, it is necessary to revisit how the dollar came to dominate global finance in the first place. In 1944, as World War II neared its end, Allied nations gathered in Bretton Woods to design a postwar monetary order. The agreement reflected the realities of power at the time: the United States emerged as the world’s leading industrial economy, held the bulk of global gold reserves, and possessed unmatched productive capacity. In exchange for stable exchange rates and access to dollar liquidity, other countries accepted constraints on their monetary sovereignty. The US dollar, convertible into gold, became the system’s anchor.

This arrangement worked for a time, but it contained the seeds of its own collapse. As global trade expanded and capital markets deepened, the supply of dollars needed to sustain growth far outstripped the US gold stock. Persistent US deficits, combined with rising foreign claims on dollars, eroded confidence in convertibility. In 1971, President Richard Nixon ended the dollar’s link to gold, ushering in the era of floating exchange rates. While many predicted that this would undermine the dollar’s global role, the opposite largely occurred.

The post-1971 system proved flexible enough to accommodate globalization and financial innovation. The dollar retained its dominance not because it was backed by gold, but because it was embedded in a vast ecosystem: deep and liquid US Treasury markets, a powerful banking system, credible institutions, and the rule of law. Over time, network effects reinforced this position. The more the dollar was used for trade invoicing, debt issuance, and reserves, the more attractive it became as a safe and convenient medium for global transactions.

Yet the global economy that sustained this arrangement has changed dramatically. China has become the world’s largest trading nation. The eurozone is a major exporter of capital. India, ASEAN economies, and other emerging markets are now central to global supply chains and energy demand. Economic power has become increasingly multipolar, but the monetary system remains stubbornly unipolar. The dollar still accounts for around 60 percent of global foreign-exchange reserves, roughly half of cross-border lending, and more than half of global trade invoicing. Even in the digital realm, the vast majority of stablecoins are pegged to the US dollar.

This mismatch between a multipolar economy and a dollar-centric monetary system has produced persistent vulnerabilities. Countries across the world remain exposed to US monetary policy, regardless of their domestic conditions. When the Federal Reserve tightens policy, global liquidity contracts. Dollar funding becomes scarce, capital flows reverse, and emerging economies in particular face severe stress. These dynamics were painfully evident during the 2008 global financial crisis, the COVID-19 shock of 2020, and the inflation-driven tightening cycle that began in 2022. Each time, emergency measures and ad hoc interventions prevented collapse, but the underlying structural imbalances remained unresolved.

Digital money now promises to alter this landscape in fundamental ways. Crucially, the most transformative element is not the creation of new currencies, but the redesign of settlement infrastructure. Tokenized assets, programmable payments, and real-time settlement systems allow value to move with unprecedented speed and precision. They reduce reliance on correspondent banking networks, lower transaction costs, and enable new forms of financial interaction. In principle, these technologies could support a more resilient, inclusive, and efficient global financial system.

However, technology is never neutral. The same digital rails that can foster openness can also be used to fragment the system along geopolitical lines. There is a growing risk that the world could drift toward a bifurcated or even fragmented monetary order, with competing digital ecosystems built around incompatible standards. In such a scenario, payments, settlements, and liquidity would increasingly flow within blocs rather than across them.

This risk helps explain why digital currency initiatives have become instruments of strategic competition. China’s development of a digital yuan and its cross-border CBDC experiments are not solely about efficiency or financial inclusion; they are also about shaping governance norms and reducing dependence on dollar-based systems. Europe’s emphasis on “digital sovereignty” reflects concerns about overreliance on US technology and financial infrastructure. Meanwhile, many emerging economies are exploring regional payment systems and alternative clearing arrangements to insulate themselves from dollar volatility and sanctions risk.

Private actors are also reshaping the terrain. Dollar-denominated stablecoins have grown rapidly, effectively exporting the dollar into decentralized digital environments. While this reinforces dollar usage in the short term, it also raises uncomfortable questions for policymakers. When private issuers create instruments that function like money, they perform quasi-central-bank roles without necessarily being subject to equivalent oversight, safeguards, or accountability.

In this context, the threat to dollar dominance does not primarily come from a rival currency such as the euro or the renminbi. Instead, it comes from the possibility that the underlying infrastructure of global finance will evolve in ways that erode the advantages that have long supported the dollar’s central role. If settlement systems fragment, if interoperability is lost, or if trust shifts toward alternative digital networks, the network effects underpinning dollar dominance could weaken.

The United States still holds powerful advantages. Its institutions remain among the most trusted in the world. Its capital markets are unmatched in depth and liquidity. US Treasury securities continue to serve as the global benchmark for safety and collateral. But in the digital era, assets alone are not enough. Architecture matters. Whoever designs, governs, and maintains the rails of digital finance will shape how liquidity circulates and where trust resides.

To preserve its central role, the US must actively engage in building the digital infrastructure of global finance. This means modernizing domestic payment systems and ensuring that cross-border platforms are interoperable rather than siloed. It requires providing clear and coherent regulation for dollar-based stablecoins and tokenized bank deposits, integrating private innovation into a robust supervisory framework. And it demands leadership in multilateral efforts to establish shared standards for digital identity, compliance, and data governance.

Such an approach would not merely serve US interests. An open, interoperable, and standards-based digital monetary order would benefit all participants. Europe and China would gain greater monetary autonomy without the inefficiencies of fragmentation. Emerging economies would reduce their exposure to external shocks and dollar shortages. Global trade and investment would become more efficient, transparent, and resilient.

Ultimately, the question of whether dollar dominance will survive digital money is inseparable from a broader choice about the future of global finance. A fragmented system, divided by rival infrastructures and incompatible standards, would be less stable and more prone to conflict. An open system, grounded in interoperability and trust, could finally deliver what previous regimes could not achieve simultaneously: liquidity, stability, and sovereignty. The digital era offers a rare opportunity to rebuild the foundations of global money. Whether the dollar remains at the center will depend not on nostalgia for past dominance, but on the willingness to lead in designing the future.
