Stablecoins: Towards Global Digital Dollarization by 2026?
In an Argentine economy where inflation exceeded 140% at the end of 2024, residents are no longer turning to local banks to protect their savings. Instead, they are choosing Tether, USDC, and other dollar-pegged tokens. This phenomenon, far from being anecdotal, reveals a profound transformation: stablecoins are creating a parallel digital dollarization infrastructure that extends far beyond the crypto sphere.
While stablecoin transaction volumes reached 27.6 trillion dollars in 2024 – surpassing Visa and Mastercard combined according to Yellow.com – the issuers of these assets are accumulating massive amounts of US Treasury bills. This dynamic raises a central question: are we witnessing a recomposition of the global monetary architecture, where the private digital dollar is establishing itself as a new benchmark?
Stablecoins, New Creditors of the US Treasury
The scale of this transformation is evident in balance sheets. Tether, the issuer of the USDT stablecoin, now holds over 120 billion dollars in US Treasury securities. This amount places it among the top five global holders of T-bills, ahead of several sovereign nations. As reported by Journal du Coin, stablecoins have become a pillar of US debt financing.
This accumulation is no accident. To guarantee the 1:1 peg between their tokens and the dollar, stablecoin issuers must maintain high-quality liquid reserves. Short-term Treasury bills are the preferred asset: safe, liquid, and yield-bearing. Standard Chartered predicts that the total stablecoin market capitalization could reach 2 trillion dollars by 2028, generating an additional demand of 800 to 1,000 billion dollars in T-bills.
This dynamic forces the US Treasury to revise its issuance schedule. Stablecoins thus become an indirect financing channel for US public debt, creating a loop where the global adoption of these tokens reinforces structural demand for US sovereign assets. An unprecedented convergence between decentralized finance and traditional finance.
Dollarization by Circumvention in Fragile Economies
Beyond macroeconomic volumes, stablecoins address a concrete need in many emerging economies. In Argentina, Nigeria, Turkey, or Lebanon, where local currencies are rapidly eroding, individuals and businesses use these tokens to preserve the value of their income and settle international transactions.
This massive adoption bypasses local banking systems and exchange control policies. Stablecoins allow funds to be transferred instantly, at lower cost, without a banking intermediary. In some regions, they are de facto becoming the daily transaction currency, gradually replacing national currencies for online purchases, family remittances, and even certain commercial transactions.
This phenomenon creates a form of digital dollarization that escapes traditional control mechanisms. Unlike classical dollarization – where physical US banknotes circulate – stablecoins operate via blockchain infrastructures accessible from a simple smartphone. The extent of this monetary migration remains difficult to quantify, but its impact on national monetary aggregates is already perceptible.
| Characteristic | Classical Dollarization | Digital Dollarization (Stablecoins) |
|---|---|---|
| Support | Physical banknotes | Digital tokens (Blockchain) |
| Access | Bank counters | Smartphone, internet |
| Intermediary | Banks | Direct, no intermediary |
| Transaction cost | Variable, often high | Low, fast |
| Exchange control | Under control | Bypassed |
The US Regulatory Framework Institutionalizes the Phenomenon
US legislation took a decisive step in 2025 with the adoption of the GENIUS Act, complemented by the preparatory work for the “Clarity Act” expected in 2026. These texts establish a clear regulatory framework for stablecoin issuers, imposing reserve, audit, and transparency requirements comparable to those of traditional financial institutions.
As analyzed by economist Eric Monnet in Le Monde, this institutionalization reveals a deliberate strategy: to strengthen the dollar's role as the reference currency for cross-border payments and liquidity reserves for non-bank actors. By legitimizing stablecoins while firmly anchoring them to the dollar, Washington extends its monetary influence through new technological channels.
Europe is responding with its MiCA (Markets in Crypto-Assets) regulation, but the asymmetry remains: dominant stablecoins (USDT, USDC) are massively pegged to the dollar, and attempts to issue euro-pegged stablecoins are struggling to reach comparable critical mass. This technological and regulatory dominance could accelerate digital dollarization on a global scale.
Challenges for Central Banks and Monetary Sovereignty
This transformation poses unprecedented challenges for central banks in emerging economies. When a significant portion of savings and transactions migrates to dollar-denominated stablecoins, the effectiveness of national monetary policy degrades. Traditional tools – policy rates, reserve requirements – lose their reach when economic agents hold and use monetary assets outside the scope of national M1 and M2 aggregates.
“With stablecoins, the United States seeks to assert its dominance over payments. If this strategy succeeds, it would constitute a major disruption, leading to the complete dollarization of emerging countries.”
— Eric Monnet, economist at EHESS
This phenomenon also creates a monetary transmission risk: monetary policy decisions by the US Federal Reserve directly impact economies that have no control over these trade-offs. A US rate hike can trigger a flight to stablecoins in countries where local monetary policy would otherwise require easing.
Central banks face a dilemma. Prohibiting or severely restricting the use of stablecoins risks pushing activity towards even more opaque channels. Conversely, allowing it means accepting a gradual erosion of monetary sovereignty. Some central banks are exploring a third way: developing their own central bank digital currencies (CBDCs) to offer a public and controlled alternative.
A Geopolitical Reconfiguration of Financial Flows
Beyond technical issues, the rise of stablecoins is reshaping geopolitical power dynamics in global finance. By transforming stablecoins into vectors of influence, the United States is extending its monetary hegemony into the digital age. Forecasts indicating a capitalization of 2 trillion dollars by 2028 suggest that this parallel infrastructure could rival certain national monetary systems.
The implications are manifold:
- Debt financing: the structural demand for T-bills generated by stablecoins eases the financing constraints of the US Treasury.
- Sanctions circumvention: paradoxically, stablecoins can also facilitate the circumvention of international sanctions, creating a blind spot for US authorities. Research on blockchain and digital currencies explores this potential impact on global finance, as indicated by Global Trend Watcher.
- Technological dependence: countries massively using stablecoins become dependent on infrastructures controlled by private US entities.
As highlighted in the AEFR report, this convergence between public and private money raises the central question of European sovereignty. The European Union, despite its economic weight, is struggling to create a euro stablecoin ecosystem capable of competing with US giants.
Scenarios for 2026: Acceleration or Regulation?
The horizon of 2026 is accompanied by major uncertainties. If the current trajectory continues, several developments are possible. Widespread adoption in cross-border payments could integrate stablecoins into traditional payment infrastructures, via partnerships with Visa, Mastercard, or SEPA systems. Multinational companies could see them as a more efficient international treasury tool than traditional banking channels.
Nevertheless, several factors could slow down or divert this trajectory. Financial stability risks remain real: a crisis of confidence in a major issuer could trigger an unprecedented digital bank run. Increasing regulatory requirements could also limit the flexibility that currently makes stablecoins attractive.
Geopolitical tensions are another factor of uncertainty. A confrontation between major powers could fragment the stablecoin ecosystem along alliance lines, creating several competing digital monetary blocs rather than a unified system. China is already developing its digital yuan according to a closed sovereignty logic, incompatible with the open approach of Western stablecoins.
The question of interoperability with emerging decentralized systems and innovative value distribution mechanisms could also influence the evolution of this ecosystem. The ability of stablecoins to integrate into next-generation payment infrastructures will partly determine their longevity in the face of alternatives like CBDCs.
Towards a New Digital Bretton Woods?
The ongoing transformation, by its scale, recalls the major monetary reconfigurations of the 20th century. After Bretton Woods in 1944, then the end of gold-dollar convertibility in 1971, we may be witnessing a third pivotal moment: the emergence of a system where private monetary assets play a central role in the international circulation of value.
Unlike previous periods, this transformation does not result from intergovernmental agreements but from bottom-up adoption, driven by technology and the needs of economic agents. States are trying to catch up with this evolution through regulation, but the gap between technical innovation and the legal framework remains wide.
The challenge for the coming years will be to determine whether this cohabitation between public currencies and private stablecoins can be stable and sustainable. Historical precedents of private currencies – from banknotes issued by commercial banks in the 19th century to local exchange systems – show that such arrangements require a delicate balance between freedom of innovation and guarantees of stability.
Stablecoins could also fuel reflection on digital scarcity, a central concept in the crypto universe but one that takes on a different meaning when applied to assets backed by fiat currencies. Unlike Bitcoin, whose supply is programmed and limited, stablecoins can grow indefinitely as long as demand exists and reserves are constituted. This elasticity brings them closer to traditional fiat money than to native cryptocurrencies.
Preparing for the Post-Digital Dollar Era
Faced with this dynamic, there are multiple possible responses. European countries could accelerate the development of the digital euro and encourage the emergence of euro-denominated stablecoins, by creating an attractive regulatory environment while ensuring stability. Emerging economies could explore regional solutions, such as stablecoins backed by baskets of currencies rather than solely the dollar.
International institutions – IMF, Bank for International Settlements – are intensifying their work on cross-border regulatory coordination. The objective: to avoid fragmentation that would create regulatory arbitrage while preserving global financial stability. Discussions focus particularly on common standards for reserves, auditing, and risk management.
For economic actors, prudence remains essential. Companies integrating stablecoins into their treasury management must assess regulatory, technological, and counterparty risks. Individuals using them to protect their savings must understand that they generally do not benefit from the deposit guarantees applicable to traditional bank accounts.
Global digital dollarization by 2026 is neither inevitable nor impossible. It will depend on the balance between spontaneous adoption, public regulation, and credible alternatives. One thing is certain: stablecoins have already crossed the threshold of the crypto niche to become a macroeconomic phenomenon that policymakers can no longer ignore.
